ITU-T G.983.1 PDF

This Recommendation is intended to describe flexible access networks using optical fibre technology. The focus is primarily on a network to support services with a bandwidth requirement greater than ISDN basic rate; it would include video and distributive services.

This Recommendation describes characteristics of an Optical Access Network (OAN) with the capability of transporting various services between the user-network interface and the Service node interface.

The OAN described in this Recommendation should enable the network operator to provide a flexible upgrade to meet future customer requirements, in particular in the area of the Optical Distribution Network (ODN). The ODN considered is based on point-to-multipoint tree and branch option.

This Recommendation concentrates on the fibre issues; the copper issues of hybrid systems are described elsewhere, e.g., xDSL standardization.

This Recommendation covers issues between the Service node interface and the User network.

Although this Recommendation concentrates on issues relating to ATM over a passive optical network, other solutions are not precluded.

This Recommendation proposes the physical layer requirements and specifications for the physical media dependent layer, the TC layer and the ranging protocol of an ATM-based Broadband Passive Optical Network (B-PON).

This Recommendation is part of the G.983.x series. The other major components of this series include:

• G.983.2 (2002), ONT management and control interface specification for B-PON.

• G.983.3 (2001), A broadband optical access system with increased service capability by wavelength allocation.

• G.983.4 (2001), A broadband optical access system with increased service capability using dynamic bandwidth assignment.

• G.983.5 (2001), A broadband optical access system with enhanced survivability.
