SFP Transceivers Options for Brocade 5100 Switch

Nowadays, many small and medium business and organizations such as local government, campus and some agencies etc., require fast and frequent access to database the files. A storage Area Network (SAN) with Fibre Channel (FC) switching technology (Figure 1) offers the speed and reliability for them. Brocade 5100 switch is an ideal Fibre Channel switch used for those organizations and can meet a variety of SAN environments.


Brief Introduction to Brocade 5100
The Brocade 5100 is a 1U Enterprise class Fibre Channel switch which combines 1, 2, 4, and 8 Gbps Fibre Channel technology in configurations of 24, 32 or up to 40 ports, getting an overall bandwidth of 320 Gbps. It is very flexible to users since it enables organizations to use 4Gbps SFPs today and upgrade to 8Gbps SFPs when required. By utilizing the sixth-generation ASIC (Application Specific Integrated Circuit) technology featuring five 8-port groups, it can reduce congestion and increase bandwidth. Because an ISL (Inter-Switch Link) trunk can supply up to 64 Gbps of balanced data throughput within these groups. In addition, enhanced Brocade ISL Trunking also utilizes ISLs more efficiently to preserve the number of usable switch ports. As shown in Figure 2, the port side of the Brocade 5100 includes the system status and power LED, console port, Ethernet port and LEDs, USB port, and FC ports and the corresponding port status LEDs. And the FC ports are numbered from left to right, in eight-port groups from 0 to 39, as illustrated in Figure 3.


Brocade 5100 ISL Trunking
As mentioned above, the Brocade 5100 can benefit from the trunking features which optimizes the use of bandwidth by allowing a group of ISL to merge into a single logical link. As we know, when ISL configured, there are certain issues like congestion. The congestion of Fibre channel links will eventually lead to performance issue and severe production impact. In this case, ISL trunking is an ideal solution to solve this issue.
As Figure 4 shown, when two switches get connected, there is a ISL link and the network traffic starts to flow through this link to the other switch. Without trunking, the congestion caused in the ISL which resulted in frames loss and bandwidth waste.
Using ISL trunking configurations, shown as Figure 5 (a), at 2Gbps speeds, the trunking delivers ISL throughput of up to 8 Gbps, avoiding the ISL congestion at the same time. In the same way, using 4 Gbps with 8 trunks can reach up to 32 Gbps, as Figure 5 (b) displayed.


Transceiver Options for Brocade 5100
Cable runs require transceivers at each end in SAN. In the SAN with Brocade Fibre Channel switches, Fibre Channel transceivers are used. Since the Brocade 5100 can support 1/2/4/8Gbps Fibre Channel, the transceiver options for Brocade 5100 are available in 1G, 2G, 4G and 8G Fibre Channel transceiver modules. Among these options, the transceivers with the data rate of 2, 4 and 8 Gbps are most commonly used in today’s Fibre Channel deployment. In addition, you can select either single-mode or multimode implementations by using the corresponding optics.
The following table shows the 2/4/8G transceiver modules that are available in infiberone.com. With strict coding technology and test assurance, these transceiver modules are highly compatible with Brocade and can achieve high performance in your Brocade 5100 switch in a cost-saving manner.

How To Clean The Recommendation for MPO MTP Connectors

MPO/MTP connectors are common throughout the high-density network today, giving us the power to add, drop, move and change the network. Thus, inspection and cleaning are very important for them since that issues with connector cleanliness and contamination are the greatest cause of network failure. However, you may find that you cannot get the expected result even though you have already cleaned the MPO/MTP connector before connection. Why? Keep reading this post, you may find out what the trouble is and how to solve it.


Understanding MPO/MTP Connector
MPO/MTP connector is the most common multi-fiber connector type used in today’s high-density networks, e.g. 40/100 Gigabit Ethernet. It usually contains one or two rows of fibers (12-fiber MPO/MTP or 24-fiber MPO/MTP) in a single connector. Compared to the single-fiber connectors, a MPO or MTP connector has a larger contact area (Figure 1), and alignment of the fibers is achieved by the connection of male connector (pinned connector) which has outer pins and female connector (unpinned connector) which has alignment holes (Figure 2).

When cleaning a MPO/MTP connector, all fibers on the connector must be clean for it to function properly. Because contamination of one fiber can cause signal degradation on other fibers. Additionally, due to the presence of the alignment pins, the cleaning of the extreme sides of the MPO/MTP connector end-face is often overlooked by users (Figure 3). This is also why we cannot get the expected result in spite of repetitive cleaning. For these reasons, we should choose the right cleaning method and tools for proper cleaning.


Cleaning Method—Dry or Wet?
Inspection should be done first before cleaning as it can decide if you need to clean. Once cleaning is required, dry cleaning which is an efficient method to remove dusts and finger grease is usually the preferred method to use due to the possibilities of residue when using alcohol based products.

However, dry cleaning method is not always sufficient to completely remove all contaminants. Thus, if the second inspection reveals that the MPO/MTP connector is still contaminated after the first dry cleaning, wet+dry cleaning method (Figure 4) is recommended to use for second cleaning. If the connector is still contaminated after second cleaning using wet+dry method, you could try to redo it once more. But in this case, permanent damage of the connector must be excluded. Once permanent damage is detected, the connector has to be replaced.

The one-click MPO/MTP cleaner (Figure 6) is an easy-to-use cleaning tool for MPO/MTP accessible connector and adapter cleaning. If connector and adapter are both required to clean in your system, it is a good choice for you. Just with a simple “one-click”, the cleaning is done. A one-click MPO/MTP cleaner can be used up to 600 cleans.


In addition to the cleaner, other cleaning accessories such as lint-free wipe, optical grade dust remover, lint-free swab, etc. are necessary to achieve dry or wet+dry cleaning.

Conclusion
Fiber optic cleaning is a key part in whole fiber optic systems. MPO/MTP connector is more susceptible to contamination due to its larger contact area and multiple fiber design. Thus, choosing a right cleaning method and cleaning tool is very important for MPO/MTP cleaning. This post recommended cleaning methods and tools for MPO/MTP cleaning.

Fiber Patch Panels Used in Data Center Interconnection Structured Cabling solution

To facilitate Data Center Interconnection structured cabling, intermediate link connections are usually made at patch panels to accommodate reconfigurations. In a structured cabling, all switches, servers and storage throughout the data center are represented by individual ports on the front of the patch panels in a centralized patching location often called the main distribution area (MDA). Connecting two ports is accomplished by a simple patch cord on the front side of the patch panels at the MDA, allowing for instant device to device connectivity.


Common Fiber Patch Panels Used in Data Center Interconnection
Structured cabling is the key to cable plant that is easy to document, manage, and grow with the current and future demands of data center connections. Three most common fiber patch panels used in structured cabling are LC adapter panels, MTP to LC cassettes, Cloud Optical Transceivers, Active Optical Cables, Direct Attach Cables and MTP adapter panels.

LC Adapter Panel – This type of patch panel module is also known as an LC-LC module and requires trunk cables with LC termination. The LC adapter panel offers the lowest connector loss of any of the patch panel modules.

MTP-LC Module – This patch panel module is also called an MTP to LC cassette and converts MTP trunk cables to LC connections. This module type has LC connectors in front and MTP connectors in back.


MTP Adapter Panel – This patch panel module supports MTP trunk cables and each MTP connection supports 8-12 fibers. The MTP adapter panel can easily support 12 MTP connections and 144 fibers or more.
Fiber Patch Panels Connections in Data Center Interconnection
In the 1 rack unit (1RU) patch panel drawn in figure below, LC adapter panel, MTP-LC module and MTP adapter panel are supported. These three types of patch panels support trunk cables terminated with MPO or LC connections. The trunk cables plug in the back of the patch panels and LC or MPO patch cords connect to the front of the patch panel. This modular patch panel architecture enables easy installation and scales well. With standard LC interfaces, this modular patch panel architecture supports 36 LC connections in a 1U patch panel. A 42RU rack full of these patch panel modules can support over one thousand fiber optic ports (42X36 = 1,512 LC ports).

Fiber Patch Panels Applications in Data Center Interconnection
Data centers often use four patch panel links that have two trunk cables radiate out from the patch panels in the MDA (shown in the figure below). In this case, each end of a trunk cable terminates in a patch panel, so four patch panels are associated with a link that has two trunk cables in it. Two of the patch panels are located in the MDA to connect any port to any port. One patch cord is needed in the MDA to connect the two trunk cables and another patch cord is needed on each end of the link to connect to the optical modules. This four fiber patch panel link has two trunk cables, three patch cords and four patch panels in all.


Conclusion
Fiber optic links are used to connect thousands of ports in massive data centers. Most data center links use MMF and support links with 2 trunk cables and four patch panels. In large deployments, more connections in more patch panels are also needed in a link and the insertion loss and link length must be managed. As the most three common patch panels used in data centers, LC adapter panels, MTP to LC cassettes and MTP adapter panels play a crucial role in structured cabling deployment. All these three patch panels are provided in INFIBERONE.COM with high quality and low price. For more details, welcome to visit www.infiberone.com or contact us over sales@infiberone.com.

The Method of Install or Remove SFP Transceiver Modules on Cisco Device

The SFP (small form-factor pluggables) transceiver modules are hot-pluggable I/O devices that plug into module sockets. The transceiver connects the electrical circuitry of the module with the optical or copper network. SFP transceiver modules are the key components in today's transmission network. Thus, it is necessary to master the skill of installing or removing a transceiver modules to avoid unnecessary loss. This tutorial are going to guide you how to install or remove SFP transceiver module in a right way.


Things Should Be Know Before Installing or Removing SFP

Before removing or installing a Transceiver Module you must disconnect all cables, because of leaving these attached will damage the cables, connectors, and the optical interfaces. At the same time please be aware that do not often remove and install an SFP transceiver and it can shorten its useful life. For this reason transceivers should not be removed or inserted more often than is required. Furthermore, transceiver modules are sensitive to static, so always ensure that you use an ESD wrist strap or comparable grounding device during both installation and removal.

Required Tools

You will need these tools to install the SFP transceiver module:
1.Wrist strap or other personal grounding device to prevent ESD occurrences.
2.Antistatic mat or antistatic foam to set the transceiver on.
3.Fiber-optic end-face cleaning tools and inspection equipment
Installing SFP Transceiver Modules


SFP transceiver modules can have three types of latching devices to secure an SFP transceiver in a port socket:

1.SFP transceiver with a Mylar tab latch.
2.SFP transceiver with an actuator button latch.
3.SFP transceiver that has a bale-clasp latch.

Types of SFP Latching

Determine which type of latch your SFP transceiver uses before following the installation and removal procedures.


To install an SFP transceiver, follow these steps:
Step 1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.
Step 2. Remove the SFP Transceiver Module from its protective packaging.
Note: Do not remove the optical bore dust plugs until directed to do so later in the procedure.
Step 3. Check the label on the SFP transceiver body to verify that you have the correct model for your network.
Step 4. Find the send (TX) and receive (RX) markings that identify the top side of the SFP transceiver.
Note: On some SFP transceivers, the TX and RX marking might be replaced by arrowheads that point from the SFP transceiver connector (transmit direction or TX) and toward the connector (receive direction or RX).
Step 5. Position the SFP transceiver in front of the socket opening.
Note: Different Cisco devices have different SFP module socket configurations. Your Cisco device could have either a latch-up or a latch-down orientation. Ensure that you are installing the SFP transceiver in the correct orientation for your Cisco device. Refer to the hardware installation instructions that came with your Cisco device for more details.
Step 6. Insert the SFP transceiver into the socket until you feel the SFP Transceiver Module connector snap into place in the socket connector.
Note: For optical SFP transceivers, before you remove the dust plugs and make any optical connections, observe these guidelines:
a. Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the transceiver optical bores until you are ready to make a connection.
b. Always inspect and clean the LC connector end-faces just before you make any connections. See the Required Tools section of this document for more information.
c. Always grasp the LC connector housing to plug or unplug a fiber-optic cable.

Step 7. Remove the dust plugs from the network interface cable LC connectors. Save the dust plugs for future use.
Step 8. Inspect and clean the LC connector’s fiber-optic end-faces.
Step 9. Remove the dust plugs from the SFP transceiver optical bores.
Step 10. Immediately attach the network interface cable LC connector to the SFP transceiver.
Step 11. Connect the 1000BASE-T SFP transceivers to a copper network.

Caution: In order to comply with GR-1089 intrabuilding lightning immunity requirements, you must use grounded, shielded, twisted-pair Category 5 cabling.

Complete these steps in order to connect the transceivers to a copper network:
a.Insert the Category 5 network cable RJ-45 connector into the SFP transceiver RJ-45 connector.
Note: When you connect to a 1000BASE-T-compatible server, workstation, or router, use four twisted-pair, straight-through Category 5 cabling for the SFP transceiver port. When you connect to a 1000BASE-T-compatible switch or repeater, use four twisted-pair, crossover Category 5 cabling.
b.Insert the other end of the network cable into an RJ-45 connector on a 1000BASE-T-compatible target device.
c. Reconfigure and reboot the target device if necessary.

Step 12. Observe the port status LED:
a. The LED turns green when the SFP transceiver and the target device have an established link.
b. The LED turns amber while STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the LED turns green.
c. If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the target device. Refer to the Troubleshooting section of your switch hardware guide for solutions to cabling problems.


Removing SFP Transceiver Modules
Step 1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.
Step 2. Disconnect the network fiber-optic cable or network copper cable from the SFP Transceiver Module connector. For optical SFP transceivers, immediately reinstall the dust plugs in the SFP transceiver optical bores and the fiber-optic cable LC connectors.
Tips: For reattachment of fiber-optic cables, note which connector plug is send (TX) and which is receive (RX).
Step 3. Release and remove the SFP Transceiver Module from the socket connector.
a. If the SFP transceiver has a Mylar tab latch, pull the tab gently in a slightly downward direction until the transceiver disengages from the socket connector, and then pull the SFP transceiver straight out. Do not twist or pull the Mylar tab because you could detach it from the SFP transceiver.

b. If the SFP transceiver has an Actuator button latch, gently press the actuator button on the front of the SFP transceiver until it clicks and the latch mechanism releases the SFP transceiver from the socket connector. Grasp the actuator button between your thumb and index finger, and carefully pull the SFP transceiver straight from the module slot.

c. If the SFP transceiver has a Bale-clasp latch, pull the bale out and down to eject the SFP transceiver from the socket connector. If the bale-clasp latch is obstructed and you cannot use your index finger to open it, use a small flat-blade screwdriver or another long narrow instrument to open the bale-clasp latch. Grasp the SFP transceiver between your thumb and index finger, and carefully remove it from the socket.
