4E1+ETH PDH Fiber optical multiplexer

Product Overview

4E1 fiber optical MUX is a point-to-point optical transmission equipment developed based on ultra large scale integrated circuit. Have perfect alarm function, data office telephone optional, full data electrocircuit, high reliability and stabilization, low power consumption, high integration, small bulk, easy installation and maintenance. The device is popularly with telecommunication operator.It is suitable in business for communication operator, government and kinds of entities.

(1) Provide 1 Ethernet interface (support VLAN, flow control, and self- negotiation; full/semi duplex, 10M/100M optional)
(2) Can provide at most 4 E1 channels transmission transparently, and 1 100M Ethernet data channel. 
(3) Provide function of E1 remote loop, order Ethernet remote loop, fiber local loop, and 1 interface of phone(optional).
