Multi-Service Fiber Mux

8ch video+1GE+2FE(Physical isolation)+8ch voice+serial+dry contact multiplexer

Overview
This series of products is a point-to-point multi-service optical transmission equipment developed on the basis of the special VLSI developed by the company. This product provides 4 channels of video 1-8 channels of telephone interfaces; 1-16 channels of switch interface/1-8 channels of RS232-422-485 interface; 2 channels of 100M Ethernet interface 1 channel of Gigabit Ethernet interface; Each Ethernet electrical port of 2 channels of 100M Ethernet has its own independent 100M bandwidth; each channel of 1 Gigabit Ethernet has independent Gigabit bandwidth and the total bandwidth of all 3 channels of Ethernet is 1200M. Optical fiber transmission is completely independent physically isolated and transmitted through a single optical fiber; 2 optical interfaces (1+1 optical backup) etc.; the internal circuit part of the device adopts all-digital circuits the whole machine is reliable and stable low power consumption and integrated High small size easy to install and maintain.
Features
