In this article, ETU-Link will explain to you what causes the high temperature of the optical module and how to solve it. Generally speaking, a brand-new optical module will not have any major problems during short-term use.     The optical module is a relatively sensitive optical device. When the operating temperature of the optical module is too high, it will cause problems s...

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 ...

DWDM is a dense wavelength division technology. This technology multiplexes the tight spectral spacing of a single optical fiber carrier in a designated optical fiber in order to utilize the achievable transmission performance. This technical solution is used to increase the bandwidth of the existing laser technology on the optical fiber backbone network. The following ETU-LINK will introduce 10G ...
