OTT 1842-1

2-Channel 3G-SDI to Fiber Transmitter (CWDM)

The OTT 1842-1 is a compact CWDM 2-Channel 3G-SDI to fiber transmitter designed to combat the restrictions involved with the distribution of uncompressed broadcast quality video signals over long distances. When combined with a 2-Channel fiber to 3G-SDI receiver module (ORR 1802-2), and the OCM 1891/1892 CWDM multiplexers it becomes a cost effective CWDM fiber system for up to 18 signals on a single fiber link.

The OTT 1842-1 has two completely independent channels. Each will auto-detect and re-clock any 3G/1.5G/SD-SDI source prior to optical transmission. The module is fully compatible with 3G Level A and Level B formats.
