E1 & V.35 Fiber Modem

Detailed Product Description

E1 & V.35 Fiber Modem

Overview

 

FBOM1000 series Fiber Modem can modulate G.703 E1 signal or V.35 signal to single-mode or multimode fiber which extend the transmitting distance of E1 signal greatly. E1 signal support framed and unframed mode. When in framed mode, continuous or discontinuous time-slot can be selected. E1 fiber modem and V.35 fiber modem can be used together. Both of them are widely used in extending user interface in ATM or DDN.

Features
