Infiberone Starts Batch Production of 40G QSFP GEN2 Optical Transceiver


Infiberone announced last Friday it’s gone into the batch production of their newly released 40G QSFP GEN2 optical transceiver. The main difference between 40G QSFP GEN2 and existing 40G QSFP on the market lies in the multichannel real-time DDM function, which is easy to realize for transceivers with data rate lower than 10Gbps, but very complicated for those more than 10Gbps, as the latter is mostly based on COB not TO packaging technique. As for parallel high-speed optical transceiver with higher rate, it requires excellent design and precise layout to realize optic circuit detection on 4-channel or 12-channel array light chip in an extremely limited space, which has been met by Infiberone patented optical engine technology. Starting optical engine technology development since 2011, now by its own endeavor and cooperation with quality suppliers, Infiberone has gained rich experience and unique technology about array LENS development and integrated optical devices coupling capsulation. It is a critical mission for Infiberone R&D long-term works that realizing multichannel optical power DDM real-time monitoring of high-speed parallel optical module. Lack of optical power real-time monitoring does not influence optical modules regular operation; however Infiberone‘s been striving to create product higher than industry standard and holds firm pursuit of optical module complete functions, and finally they reach this goal.

It says that Infiberone new launched GEN2 optical module will not largely increase clients’ purchasing cost. The bulk price of GEN1 and GEN2 almost reach equilibrium, even GEN2 module is a truly flawless product compliant with related standards. Infiberone launched this new product at CIOE in September 2015, and now plans to completely switch the generation products in the first half of 2016.

By the way, Infiberone is going to attend OFC exhibition in USA this month, let's meet there to communicate about new products.

How to 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

The main technical trends of optical communication


In the field of optical communication, different companies hold different opinions about the trends of this industry. But we would like to talk about our ideas today to share with you all.
The main trends of current optical products including:
A miniaturization and integration;
B miniaturization and lower cost;
C higher speed and larger capacity;
D lower power consumption;
E closed proprietary to open and flexible.

Smaller, more integrated, lower cost, lower power consumption, greater capacity, in fact, is the development trend of optical communication products. And the last one(E) to open and flexible,  is the new trend of SDN technology, but also the most important trend.

Miniaturization, integration, low cost, high speed, large capacity and low power consumption, all these have been the requirements of optical communication products in different times. But they present different details in different times even they always combine each together. In 2016, the ultra small PD of German Karlsruhe Institute, TE micro QSFP, QSFP DD and other MSA are on behalf of the development of this miniaturization technology. In the aspect of the integration technology, silicon photonic is very hot this year, but not the only option. In fact, integration is not only the integration of the chip level, the current integration of active devices and passive devices is also a kind of integration. There are very few individual passive or active devices.

Optical communications manufacturers have been committed to reducing costs and power consumption. The emergence of the ACO CFP module is a cost reduction effort. COBO alliance’s goal is to reduce cost, but also to reduce power consumption. The emergence of the technology is directly related to the needs of the system vendors. Ignoring the impact of these trends, today's dominant manufacturers may fall behind. These technological changes are more important for China's optical communications companies, because these technologies may be more likely to change the package. After all, to make progress like Ranovus in the quantum dot chip is not easy for Chinese manufacturers.

High speed and large capacity is always the goal of optical communication companies. Current hot spots in this area are related to modulation techniques and optical fibers in the 400Gbps and more high speed systems. Compared to the pursuit on the 400Gbps and the experiment, China's optical communication companies should pay more attention to the 25Gbps system. Regardless of Ethernet, PON or 5G mobile communications, 25Gbps will become an important rate in the near future.

From the closed proprietary OEM network equipment to steering flexible reconfigurable open platform is the most important trend in optical communication technology this year since OFC. TIP of Facebook shows ADVA and other equipment companies will support open source optical network equipment plan. From closed to open is the trend of the Internet era, and optical communication will not be forever excluded. How to make our products more flexible and how to support open source, these should be the important issues in the next two years of us all.

High Density MPO/MTP Cabling System


Typical Application Scenario—Data Center SAN
In today’s fast-moving cyber world, with the advent and popularity of cloud computing and big data, the demand for high-speed transmission and data capacity is becoming much greater than ever before. There exist millions of servers in some cloud-computing data centers of big IT giant companies like Google, Facebook, Tencent, thus, how to balance high capacity & high transmission data rate and low power consumption is a major challenge facing today’s data center. In the mean time, the prevalence of smart phone, i-pad and other intelligent equipments leads to the data explosion than expected, which all has a more demanding request for higher network capacity.

As the data throughput increases, 40Gb/s and 100Gb/s are more commonplace and now become a trend and hotspot for data-center cabling system, plus the fact that MPO/MTP connector is the up-and-coming standard optical interface for 40G and 100G Ethernet network, so it is predicted that MPO/MTP will eventually replace the standards for fiber optics as known. Even now many big IT companies are tearing out their existing infrastructure and placing MPO/MTP cassettes in their patch panels to route data for thousands of network electronics, they find MPO/MTP cassettes, patch-cords, connectors and adapters an essential backbone to their infrastructure. If you run one 12-fiber MPO/MTP cable from a cassette on one side of the building to one cassette on the other, you can supply data for 12 connections just like that. The high fiber count in one connector creates endless possibilities. Imagining a 1U rack mount patch panel that can supply data to run an entire 288-port switch, it will happen soon with today's increasing demand for higher through-put, so the needs for. FC, LC, SC, ST, MT-RJ, etc., will all be a thing of the past.

Infiberone, as a cabling solution provider, is now going to be ahead of the game with MPO/MTP cables that are designed for the reliable and quick operations in Data Centers.
