Understanding of the 100G QSFP28 optical module

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?

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..

Optical modules and fiber jumper selection of storage area network

Optical modules and fiber jumpers are the most important infrastructure for network connectivity. In the storage area network (SAN), a switch is used between the server and the storage device, that is, interconnections between the server and the switch, the storage device, and the switch as well as between the switches are achieved by optical modules and fiber jumpers. Of course, depending on the specific application, we have to choose the most appropriate optical modules and fiber jumpers in order to achieve the best performance. In addition to considering the performance, we also need to take the future expansion of the network and other issues into account. Therefore, it is necessary to develop a cost-effective optical module and fiber jumper solution.Key factors that affect the selection of optical module and fiberAs we mentioned above, the SAN is mainly composed of servers, storage devices, and switches, then we have to take into account the specific circumstances of the server, s..

Guide of Installing/Removing the SFP RJ-45 Optical Module

The optical module integrates precise optical elements and circuit elements. In the daily use, operation by specification should be noticed; otherwise, the optical module is easily broken. Do you know that there is SFP electrical port module in SFP optical module? How to install and remove SFP electrical port module? The article will give a detailed introduction to the specification of SFP electrical port module's installation and removal.1. Introduction to SFP Electrical Port ModuleOne terminal of SFP RJ-45 module is SFP gold finger connected with the main engine, and the other terminal is common LC interface connected with the optical patch. But sometimes live environment requires using RJ45 interface to connect with a copper network cable. But Internet interface of the device is not enough. Then SFP interface must be transited toRJ45 interface. The former is such an application that one terminal is SPF gold finger and the other terminal is an RJ45 interface with the general speed ra..
