Indoor Cabling Standards drive requirements for truly Bend Insensitive Optical Fiber

Inhalt:
In general, telecom regulatory bodies are keen to foster competitive broadband access markets. Hence, there is a trend emerging in Europe as well as globally, of regulation being drafted to enable open access indoor architecture, configured so that all operators can provide a service regardless of system design (e.g. GPON, EPON, P2P, CATV-RF-Overlay, etc.). By closely defining the specification boundaries of the passive components of the optical infrastructure in a building, such regulation can ensure that the infrastructure can be used by a myriad of network operators regardless of differences in their respective transmission system technologies. A standardized indoor cabling infrastructure for joint utilization will enable competitive service offerings, faster fibre to the home (FTTH) deployment, operational cost savings, and consumer driven format and content innovation. Access network transmission systems have stringent power budgets, failure to meet the power budget results in service outage; leading to revenue disruption and customer dissatisfaction. The performance of the cable infrastructure greatly determines the power budget performance. This document describes how bend insensitive single-mode optical fibre according to the ITU-T G.657 A3/B3 (A3 being the proposed G.657 sub-category fully compatible with the ITU-T G.⁶⁵²D standard and offering ultra low bend loss capability) can enable virtually zero bend loss in FTTH indoor cabling and the best link power budget protection in the Open Access architecture environment.
