Optical modules can be classified into single-fiber and dual-fiber according to the number of interfaces. Dual-fiber optical modules have two optical fiber interfaces, and single-fiber optical modules have only one optical fiber interface. In addition to the difference in optical fiber interfaces, the use of the two is also different. Therefore, ETU-LINK will introduce the precautions for the use ...

In this article, ETU-LINK will introduce to you, what is the difference between active optical cable(AOC) and direct attach cable(DAC)? First, the AOC is composed of integrated optoelectronic devices. The signal transmission process is that the A terminal module converts the electrical signal into an optical signal, the optical signal is transmitted to the B terminal module by an optical fiber pat...

The previous storage technology only uses the storage device as an auxiliary device of the server. The large-capacity data exchange between servers can only rely on traditional networks, and cannot adapt to the development of IT technology in terms of speed, security, cross-platform sharing, and unlimited expansion. Under such circumstances, SAN technology came into being. Fibre Channel SCSI techn...

In the establishment of a 10G network, we will face a choice, that is, whether we choose optical fiber cabling or copper cabling. Optical fiber cabling systems are divided into multi-mode（MM) optical fiber cabling systems and single-mode(SM) optical fiber cabling systems, among which 10G MM optical fiber cabling systems need to use 10G SFP+ MM optical modules, 10G AOC active optical...
