Product Description
1 Overview
Ethernet Optical Fiber Modem is used for accomplishing the converting between the Ethernet port and the E1 port (Physical Connector is optical interface). It provides a 2M bandwidth data transmission channel for Ethernet through optical fiber. It is suitable for many situations, such as increasing the range of LAN, founding a special Ethernet network, and so on.
