Overview of Optical Switch:
fiber optic switch is a high-speed network transmission relay device. Compared with ordinary switches, it uses fiber optic cables as the transmission medium. The advantages of optical fiber transmission are fast speed and strong anti-interference ability. Fibre Channel Switch (FC Switch, also called ”Fibre Channel Switch”).
Fiber optic switch is a new type of equipment, and there are too many differences from the usual Ethernet switches that are used (mainly reflected in the support of the agreement). Huawei fiber optic Ethernet switches are a high-performance management Type two layer fiber optic Ethernet access switch. The user can choose the all-optical port configuration or the optical-electrical port hybrid configuration, and the optical fiber media can be single-mode fiber or multi-mode fiber. The switch can support network remote management and local management at the same time to realize the monitoring of port working status and switch settings.
The optical fiber port is particularly suitable for situations where the access distance of the information point exceeds the access distance of the Category 5 line, the need for anti-electromagnetic interference and the need for communication confidentiality, etc. The applicable fields include: residential quarters FTTH broadband access network; enterprise high-speed optical fiber LAN; high-reliability industrial distribution Control system (DCS); optical fiber digital video surveillance network; hospital high-speed optical fiber local area network; campus network.
