Fiber Optic Modem 1.E1 digital interface(75/120ohm) 2.V.35 interface 3.RS232 asynchromous data interface 4.E1 and V.35

Multi-service SPC-155M Fiber modem

Introduction

The SPC-155M Multiservice Fiber Optic Modem is manufactured based on Spacecoms proprietary purpose-built integrated circuits. It integrates the traditional 2M E1, 10/100Base-Tx (max bandwidth: 100M), and N×64K V.35 services in one equipment so that it can operate both high-speed digital service and traditional TDM service in one pair of Fiber. It can also provide centralized rack structure for easy maintenance as well as plug and play, and at the same time, provide complete network management functions.
