Description
Overview
GAOTek ethernet Fiber Converter has carrier-class, high compact platform and aimed for metro and SDH networks access. It can work as Add-Drop Multiplexer (ADM), Termination Multiplexer (TM), and as a Gigabit Ethernet to SDH converter. With extremely strong cross-connection ability, it supports 64K up to low or high order of SDH cross-connection. Not only can the STM-1 or STM-4 optical port work as the network uplink, but it can also configure the n x E1 ports as the network uplink simultaneously.
