HD-SDI Fiber optical transmission System

Introduction: 

1.Overview

The KW3010-HD/SDI allows you to transmit 3G, HD or SD-SDI as per SMPTE 424M-2006, 292 and 259, with or without embedded audio and data, as well as DVB-ASI over one single mode or multimode fiber. Signals are equalized and re-clocked prior to fiber optic transmission. The transmitter features a re-clocked and equalized SDI loop through and the receiver features two re-clocked and equalized SDI outputs.

2. Features
