Prisma and Laser Link DWDM Passives for LGX-Compatible Systems

Transcription

1 Optical Passive Components Prisma and Laser Lk DWDM Passives for LGX-Compatible Systems Description Competitive pressures and rapidly acceleratg user demand for teractive services are forcg cable operators to upgrade their network architectures. These changes are pushg optical fiber deeper to the network. But simply replacg existg transmission les with fiber is no longer the most cost-effective means to handle creasg bandwidth requirements. Operators are now takg advantage of advancements optical filterg that have made it possible to significantly crease the number of signals (or wavelengths) that can be carried on a sgle fiber - a process known as Dense Wavelength Division Multiplexg (DWDM). Prisma and Laser Lk Multiplexer (MUX) and Demultiplexer (DMUX) components are essential elements for implementg DWDM to crease network efficiency by significantly reducg fiber counts. These units are now available the dustry recognized, LGXcompatible form factor to allow easy, snap- mountg a variety of enclosures and cabets. The LGX modules can be used the same chassis as coupler/splitters and patchg modules to achieve highdensity rack configurations. The Prisma and LaserLk MUX and DMUX components are also optimized to achieve low sertion loss at all wavelengths. Features Prisma and LaserLk MUX and DMUX modules available 4, 8, 12, 16 and 20 channel configurations Sgle channel Optical Add-Drop Mux (OADM) available for greater design flexibility Channels spaced at 100 GHz or 200 GHz, followg the standard ITU wavelength grid Wavelength mappg options allow combation of broadcast and narrowcast services on a sgle fiber Prisma and LaserLk MUX and DMUX modules support analog and digital forward path transmission applications, and reverse path transmission applications such as baseband digital reverse (bdr ) to significantly crease bi-directional throughput Prisma MUX and DMUX pairs optimized for the lowest combed sertion loss across all wavelengths Laser Lk universal module for both Mux and Demux applications LGX-compatible modules easily snap to a wide variety of enclosures and cabets Industry-standard SC/APC adapters ensure connector compatibility; mimize back reflection and sertion losses; simplify moves, adds & changes; and reduce connector matenance requirements
