1. 1. 1. 1. Introduction

Introduction

MODEL7304 is a high-performance V.35 optic fiber modem developed by using a dedicated

integrated circuit. It is to modulate a N×64K V.35 data signal directly over single- or

multi-mode optic fiber for a transmission via optic cable line. At another end of the optic

cable, optical signal is demodulated into a V.35 data signal. V.35 interface may be directly

connected with the V.35 interfaces of image and data terminals or the WAN ports of MUX,

exchanger and router for a dedicated network setup or a LAN connection.
