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.

HDTx-M
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*.
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.

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.
