OTT 1812-1

2-Channel 3G-SDI to Fiber Transmitter

Datasheet

Quick Reference

The OTT 1812-1 is a compact 2-Channel 3G-SDI to fiber transmitter designed to address the restrictions involved with the distribution of uncompressed broadcast quality video signals over long distances.

When paired with the 2-Channel fiber to 3G-SDI receiver (e.g. yellobrik ORR 1802-2) it becomes a cost effective dual channel optical transmission / receiver system for 3G-SDI signals up to 1080p60.

The OTT 1812-1 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. It can be pre-assembled with a Single-mode 1310 nm SFP. CWDM SFPs support significantly longer optical distances and must be ordered separately with the required operating wavelength.

Like all yellobrik modules, it is compatible with the RFR 1200 rack frame, which provides power redundancy.
