SCTE commences development of RF-over-glass standards
March 31, 2008
EXTON, Pa. -- In an effort to cost-effectively improve the customer experience and help the industry prosper, the Society of Cable Telecommunications Engineers (SCTE) recently launched development of a landmark suite of technical industry standards to support wider use of optical fiber in the cable plant.
Focused on a technology called RF over Glass, the standards will enable cable systems to reap the benefits of an expanded use of optical fiber while continuing to deliver the complete array of current cable services and technologies, including DOCSIS®.
The American National Standards Institute (ANSI)-accredited SCTE Standards Program is directed by the SCTE Engineering Committee, which approved the RF over Glass work program last fall and assigned the program’s projects to the SCTE Interface Practices Subcommittee (IPS) for development as industry standards. The IPS Subcommittee then met in mid-March near SCTE headquarters in Exton (suburban Philadelphia), Pa., to begin crafting the standards.
Once developed and approved as standards, RF over Glass will greatly broaden the SCTE Standards Program’s footprint concerning optical fiber. SCTE currently has two approved standards in this area: ANSI/SCTE 122 2006, SCTE Recommended Optical Fiber Cable Types for Outside Plant Drop Applications and ANSI/SCTE 86 2005, SCTE Recommended Optical Fiber Cable Types for Outside Plant Trunk and Distribution Applications.
Part of IPS’s RF over Glass focus in the early going has been on a document titled IPS SP 910, RF over Glass System Overview. This working document addresses DOCSIS® and cable television’s Hybrid Fiber/Coax (HFC) systems, an environment where data and video share the same RF spectrum.
