In today's Internet era, both enterprise network deployment and data center construction are inseparable from optical transceivers and switches. Optical transceivers are mainly used to convert electrical and optical signals, while switches are used to forward photoelectric signals. Among many optical transceivers, the SFP+ optical transceiver is one of the most widely used optical transceivers. Wh...

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 ...

As an important part of the optical network transmission, the optical fiber module functions as a photoelectric conversion, so that the signal can be transmitted in the optical fiber. So, do you know how to distinguish whether an optical fiber module is single-mode or multi-mode? Next, ETU-LINK will teach you a few ways to distinguish between multi-mode fiber modules and single-mode fiber modules....
