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.

The HDTx-M transmitters have 1 GHz passband which greatly increases bandwidth for high

definition TV and other advanced services. Microprocessor control allows ease of installation and

flexibility of application.
