Overview of Optical Switches:
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. Optical fiber switch (FC Switch, also known as “Fibre Channel switch”).
Fiber optic switch is a new type of equipment, and there are too many differences from commonly seen and used Ethernet switches (mainly reflected in the support of protocols). fiber optic Ethernet switch is a high-performance management Type 2 optical fiber Ethernet access switch. Users can choose all-optical port configuration or optical port hybrid configuration, and the access fiber media can choose 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 especially suitable for the information point access distance beyond the five-category line access distance, the need for anti-electromagnetic interference and the need for communication confidentiality, etc. The applicable fields include: residential 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.
