Description / Abstract:

This standard defines the transport of Multi-Link (ML) or Multi-Channel (MC) SDI data streams over a single fiber using Coarse Wavelength Division Multiplexing (CWDM).

Specifically, this standard specifies a CWDM optical interface for Multi-Link 12G-SDI, Multi-Link 6G-SDI, Multi-Link 3G-SDI and Multi-Link 1.5G-SDI, as well as Multi-Channel 12G-SDI, 6G-SDI, 3G-SDI and/or 1.5G-SDI.

To conform to this standard, It is not necessary for implementations to include support for both Multi-Link and Multi-Channel modes, nor is it necessary to support all interface data rates defined in Table 1. Implementers should indicate supported interface rates and operating modes in commercial publications.
