  • 3Gbit Level A and Level B support (all formats)
  • Auto reclocking 270Mbit / 1.5Gbit / 2.97Gbit
  • Error free optical transmission
  • 18 Wavelength selections (ITU-T G.694.2)
  • Up to 40km (24.8 miles) @ 3Gbit/s
  • Duplex LC/PC single mode optical connections
  • Supports hot swapping and hot plugging


The OTT 1842 is a compact CWDM dual channel SDI to fiber optic transmitter designed to combat the restrictions involved with the distribution of uncompressed broadcast quality video signals over long distances. 18 wavelength choices are provided.

When combined with the dual channel fiber optic to SDI receiver module ORR 1802, and the OCM 1891/1892 CWDM multiplexers you have a very cost effective CWDM fiber system for up to 18 signals in a single fiber link.

The OTT 1842 has two completely independent channels and each will auto-detect and re-clock any 270Mbit / 1.48Gbit and 2.97Gbit SDI source prior to optical transmission. The module is fully compatible with 3Gbit Level A and Level B formats.

Note. The module does not include a fiber SFP sub module, one must be specified from the options list
