Cisco Prisma II Multi-Wavelength High Density Transmitter

Increasing customer demands for advanced services and 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 Prisma II Multi-Wavelength High Density Transmitters (HDTx-M) and complementary O-band 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). The transmitters are offered in a range of output powers from 4 dBm to 12 dBm to increase network design flexibility.

The HDTx-M transmitters may be used in either the new Prisma XD high density chassis or in the standard Prisma II chassis.

• When used in the 6 RU standard Prisma II chassis, a Host Module is used to interface between the chassis and the high density transmitter (or receiver) modules. 2 high density modules occupy each single-wide host module. The Prisma II standard chassis can accommodate up to 26 high density modules. High density modules can be mixed with other full-height PII modules in the chassis.
• When used in the 3 RU Prisma XD chassis, the high density modules plug directly into the chassis without host module. The Prisma XD chassis can accommodate up to 16 high density modules.
