AOC active optical cable has the characteristics of low power consumption, small size, light weight and strong heat dissipation. Compared with copper cable, it has a longer transmission distance and better transmission performance. Compared with the optical module, the active optical cable does not have the problem of interface pollution, which greatly improves the stability and reliability of the...

Network generic cabling is becoming more and more popular. As a high bandwidth and high security data transmission medium, optical fiber cable is widely used in various large and medium-sized networks. However, due to the high cost of optical fiber cable solutions, in some cases, copper core high-speed cable still plays an important role. For example, 10G SFP+ DAC direct attach cable is the high p...

DWDM (dense wavelength division multiplexing) is the preferred technology in today's optical fiber applications, but the price is relatively expensive. In comparison, CWDM (sparse wavelength division multiplexing) is a low-cost WDM transmission technology for the access layer of man. Now ETU-Link will introduce 10g SFP+ CWDM / DWDM optical module. 10G SFP+ CWDM optical module: 10G SFP+ CWDM optica...

In 40G/100G data center cabling, many engineers ask: How to connect MPO optical module to LC optical module? How to connect 40G QSFP+ (MPO) to 10G SFP+ (LC)? What cables and panels are needed? At present, there are usually two types of optical modules in the market: MPO and LC. For two optical modules with the same interface, MPO patch cord or LC patch cord can basically realize the connection bet...
