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...

According to the working temperature range, optical modules can be divided into commercial (0℃ - 70℃), expansion (- 20℃ - 85℃), industrial (- 40℃ - 85℃). Generally, only commercial optical module is needed for indoor optical module, but industrial optical module is needed if the optical module is used in outdoor environment with uncertain and fluctuating temperature (such as remote mountain area, ...
