Today, we will learn about optical fiber channel module, Ethernet optical module, and what is the difference between them? First of all, let's understand what fibre channel optical module is. It follows the fibre channel standard and is mainly used in the data center fibre channel storage network link. Its transmission rate can support 1-128Gbps at present. Common packages include SFP, SFP+, ...

The Fibre Channel protocol was formulated by the X3T11 team of ANSI in 1988. It has the characteristics of high bandwidth, multi-media, and long-distance transmission. It can realize the transmission of large data files between storage, server and client nodes. In this article, ETU-LINK will focus on introducing the 16G FC DWDM SFP+ series optical modules for 16G Fibre Channel networks. ...

As we all know, DAC active cable is mainly used for interconnection between cabinets. Due to the limitation of passive copper cable DAC transmission distance due to material, high frequency loss of connector and other factors, the maximum length of passive copper cable DAC with transmission rate of 10G/25G can only reach 7m, and the maximum length of passive copper cable DAC with transmission rate...

With the rapid development of the communication industry and data centers at home and abroad, the demand for optical modules has increased sharply. The production capacity of brand original optical modules is limited and the number is small, so the price is relatively expensive and the user's use cost is high. In view of this market phenomenon, many manufacturers of dual capacity optical modules h...
