The optical module is an important component of the optical fiber communication system, which is used to realize the transmission and reception of optical signals. The speed of the optical module used in the data center ranges from 1G before 2010 to the commonly used 10G and 40G now. Since most of the equipment distance in medium and large data centers is within 500 meters, the interconnection bet...

This blog ETU-LINK takes everyone to understand the difference between optical fiber, copper cable and twisted pair. First of all, let’s understand the twisted pair. The twisted pair is made up of multiple groups of insulated copper wires intertwined. The internal medium of the twisted-pair cable is also copper wire, and the internal transmission is an electrical signal. According to the principle...

The Fibre Channel switch originated from the Fibre Channel protocol. On the fourth layer of the Fibre Channel protocol, the Fibre Channel-based SCSI protocol for storage, the IP protocol for the network, and the virtual interface (VI) protocol for clusters mapped to the network architecture are established. Fibre Channel switches provide Fibre Channel switching for high-bandwidth and low-latency d...

SAN refers to the regional storage network, which needs to be connected by optical fiber, and the operation mode of the SAN mainly depends on the hardware. The structure of the SAN allows any server to connect to any storage array so that the server can directly access the data it needs no matter where it is located. Due to the optical fiber interface, the SAN also has a higher bandwidth. The SAN ...
