Description
16E1+4Ethernet fiber optical multiplexer is point-to-point optical transmission equipment developed based on ultra large scale integrated circuit. Have perfect alarm function, data office telephone optional, full data electro circuit, 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.
Features
Provide 1 Ethernet interface (support VLAN, flow control, and self- negotiation; full/semi duplex, 10M/100M optional)
Can provide at most 16 E1 channels transmission transparently, and 1 100M Ethernet data channel.
Provide function of E1 remote loop, order Ethernet remote loop, fiber local loop, and 1 interface of phone (optional).
Jitter tolerance much better than GB.
Power supply option: AC220V, DC-48V. The positive and negative terminal can be exchanged for DC-48V, easy for installation and maintenance.
Network manager interface use SNMP
