Description
Overview
 GAOTek VLSI-Based Fiber Optic Multiplexer, 1.5 Gbps, 64 x E1 Interfaces is the point-to-point optical transmission device developed based on VLSI. The device provides 1 to 64 x E1 interface, 1 to 4 x 10 or 100 or 1000 M Ethernet interface (Wire Speed 1000 M) and 2 expansion interfaces. 4x Ethernet interface is switch interface, can support VLAN. 1 expansion interface can be used as the transmission channel of RS232 or RS485 or RS422 asynchronous data, dry contact signal, 1-Channel digital business phone can be optional. It is very flexible. It has alarm function. The work is reliable, stable, and low power consumption, high integration, and small size.Â
