With the growing demands for bandwidth that makes 100G network developed rapidly. 100G optical module is to be an important part of 100G network, and now many standards and form factors has been emerged on the market. Here we will introduce the related knowledge about 100G optical module in detail.The types of 100G optical moduleAccording to different form factor, 100G optical module can mainly be divided into CFP／CFP2／CFP4、CXP and QSFP28. Among them, CFP／CFP2／CFP4 and CXP is the early form factor of 100G optical module, but QSFP28 is the new-generation form factor of 100G optical module, which is become the mainstream form factor of 100G optical module now. The principle of 100G QSFP28 optical module is similar to 40G QSFP+’s which adopts the way of 4 x 25 Gbps to transmit 100G optical signal.CXP optical moduleThe transmission rate of CXP optical module can reach 12 x 10Gbps, supports hot-pluggable, is the supplement of CFP optical module in the Ethernet data center. The size of CXP i..
For most data centers and network service providers, if you want to be competitive, you must continually improve your network speed to meet people's growing network needs. Over the past few years, 40G networks is very popular, and now according to authoritative statistics, by 2018, the world will have 38% of service providers to deploy 100G network, which means 100G era has arrived. 100G optical module is an important part of the 100G network, and 100G QSFP28 optical modules is the industry's most respected 100G optical module, this tutorial will be introduced in detail.About 100G QSFP28 optical modulesThe encapsulation of 100G QSFP28 optical module and 40G QSFP + optical module is the same , and both are using four Fiber Channel to transmit data, the difference is that the transmission rate of 100G QSFP28 optical module fiber channel can be up to 28Gbps, mainly for 100G transmission applications Compared to 100G CFP optical modules, the 100G QSFP28 optical module is better suited for ..

100G network development direction is 10G → 40G → 100G, 100GBASE QSFP28 optical module appears, there are already some data centers have begun to use this method before the emergence of 100Gase QSFP28 optical module (one can support the 100G transmission of optical modules) to achieve the 10G upgrade to 100G. So, the question came, why would there be the 100GBASE QSFP28 light module? Does the QSFP28 optical module completely replace other 100G optical modules? How will the QSFP28 optical module change the data center? After reading this article, I think you will find the answer.Advantages of QSFP28 optical modulesThe cost and power consumption of the data center is one of the important factors that its builders need to consider, which is also an important driving force for the development of optical communication market. Looking back on the development of the 100G optical module, the development and improvement of its packaging style (CFP, CFP2, CFP4) and standards are mainly focused o..

With the rapid development of optical communication in recent years, users have increasing demands for the network. In this condition, 100G optical module has become the hot focus that users care. What is a 100G optical module? This post will give a complete introduction and guide about 100G optical modules.1. Introduction of 100G optical modules100G optical module was created to adapt to the trend that network market is developing to 40G and 100G, with a transmission rate of 100G, this module plays a significant role in 100G network system deployment.2. Technology development of 100G optical modulesCompared with the 2.5G, 10G or 40G wavelength division transmission systems, the 100G optical transmission uses the digital coherent receiver to map all the optical attributes of the optical signal to the electric domain through the phase diversity and the polarization state diversity. Using the mature digital signal processing technology achieve in the electric domain polarization demultip..
