Deployment status and common technical specifications for a B-PON system

Abstract

Broadband passive optical networks (B-PONS) have entered the commercial deployment phase in North America, Japan, and Europe. Nippon Telegraph and Telephone, BellSouth, France Telecom, British Telecommunications plc, and SBC have developed a set of common technical specifications for a B-PON system based on ITU-T Recommendations G.983.1, G.983.2 and G.983.3. They have deployed or plan to deploy B-PON systems based on t h i s CTS. This article describes B-PON interface features, the outline of CTS, and the deployment status of the B-PON systems around the world.

Optical Networks for the Broadband Future

“…From an operator's perspective, cost reduction is the key motivator for standards [10]. Interoperability and second sourcing are also important for derisking investment.…”

“…The Common Technical Specifications (CTS) Task Group brings together a (minimum) set of common requirements and standards into a single document to be used by operators when purchasing optical access systems. It is used as part of the documentation needed in a tendering exercise [10]. The third group is the Next Generation Access Task Group and is investigating future generations of optical access to give improvements such as increased capacity, reach and lower cost.…”

Recent developments in PON systems standards in ITU-T

“…From an operator's perspective, cost reduction is the key motivator for standards [4]. Inoperability and second sourcing are also important for a de-risking the investment.…”

Standardization Activities on Broadband Access Systems

“…FSAN also contributes to BPON deployment by establishing interoperability of B-PON equipments and CTS (Common Technical Specifications) for B-PON [15]. The interoperability aims to guarantee multi-vendor interoperability, and CTS is the basis of multi-carrier common specifications.…”
