ITU-T G.9802.2 PDF

This Recommendation, as part of the multiple-wavelength passive optical network (MW-PON) ITU-T G.9802 series Recommendation, specifies a PON system utilizing a wavelength multiplexer in the optical distribution network (ODN).

The specifications of both the physical media dependent (PMD) and transmission convergence (TC) layers of WR-ODN based WDM PON are captured in this recommendation.

The PMD layer specification includes aspects such as the reference logical architecture, wavelength plan, optical path loss, transmitter and receiver specifications, compatible ODN, etc.

The TC layer specification includes the details of the forward error correction (FEC) code, implementation methods of the management channel, management functions, a set of processes and messages, etc. to provide similar operation experience as legacy PON systems, e.g., silent start and capability to map a local physical layer operation, administration and maintenance (PLOAM) channel.
