O-Band Optical Passives
Increasing customer demands for advanced services and escalating
competitive pressures are causing HFC network operators to consider
strategic options. One popular alternative involves segmentation of the
network to reduce service group size and increase effective per-home
bandwidth.
Cisco’s advanced O-band multi-wavelength optical transmitters and
complementary optical passives provide innovative and economical forward
path segmentation solutions in areas with fiber count limitations. Multiple
optical wavelengths carrying differing content are multiplexed for transport
on a common fiber and demultiplexed to feed the segmented service areas.
Optimal performance is achieved by making use of up to six carefully
selected O-band optical wavelengths (channels).

LGX Filter
The Prisma O-band optical passives are designed to be used in
conjunction with Prisma II Multi-wavelength High Density Transmitters.
The passive optical multiplexers and demultiplexers (mux/demux) have
filtering that match the transmitter wavelengths channel for channel, and
are optimized for low insertion loss across the band. The indoor
mux/demux units are available in industry recognized LGX form factor to
allow easy, snap-in mounting in a variety of enclosures and cabinets. The
demux is additionally packaged in cassette form for field deployment in
extreme environmental conditions. A single channel Optical Add-Drop Mux
(OADM) is also available in a raw filter package for field deployment.
