DVI-7345

Quick Start Guide

Introduction

High Performance – The DVI-7345 is an ultra-compact, high performance ber optic extender

that supports SDI, HD-SDI and 3G-SDI extension over a single strand of Single-Mode optical ber at
distances up to 1.2 miles (~ 2000 meters). The extender set consists of an optical transmitter module
that converts the SDI signals into light pulses for transmission over a single strand of Single-Mode
optical ber cable. An optical receiver module converts the light pulses back to an SDI signal for
downstream processing or display on a monitor.

Superior Design – The transmitter includes an SDI signal EQ, a Laser driver and a laser diode

module that uses a single optical wavelength of 1310nm. The receiver includes an SDI copper cable
driver, a photo diode, a TIA, as well as a limited amplier. Both Tx and Rx use low-prole, metal
cases equipped with rugged locking 75ohm BNC SDI connectors. The locking ST ber connectors are
supplied with twist-locking metal covers to prevent dust buildup inside the ber optic connectors.
These features make the DVI-7345 the perfect solution for extension of SDI, HD-SDI, and 3G-SDI
signals over extreme distances in even the most demanding broadcast, studio, and live environments.
