100G optical modules, core solution to high-speed network system
Posted on Jul 05, 2017 by cozlink.com
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..

With the widespread use of 40G Ethernet, in order to further achieve higher bandwidth and throughput requirements, 100G has become the trend of data transmission. The 100G QSFP28 series of products’ attention is creasing in the 2016 years of the United States optical fiber communication exhibition and seminar (OFC), while the subsequent 100G QSFP28 standard announcement also means that 10G / 40G to 100G network migration has added a new s solution. This article will provide several common 100G QSFP28 high-speed cable solutions and several popular products for your choice.Solution 1: 100G QSFP28 to QSFP28 high-speed cable100G QSFP28 high-speed cable, direct use of a cable to a QSFP28 interface and another QSFP28 interface connection for short-distance QSFP28 devices between the stack and set, has a great cost advantage. 100G QSFP28 to QSFP28 high-speed cable has four transmission channels, because the transmission is 100G signal, so this high-speed cable will be 100G electrical signal 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 ..
Is the QSFP28 optical module a better solution for the 100G network?
Posted on May 24, 2017 by cozlink.com
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..
