High Density Transmitter Description
Prisma II High Density Transmitters are plug-in modules for the Prisma II and
Prisma II XD platforms. These modules are part of the Prisma II optical network, an
advanced transmission system designed to optimize network architectures and
increase reliability, scalability, and cost effectiveness.
The transmitter installs into a Prisma II XD Chassis directly, or into a standard
The transmitter installs into a Prisma II XD Chassis directly, or into a standard
Prisma II Chassis by means of a host module that accepts up to two Prisma II High
Density application modules.
Inside the transmitter, multiple optical wavelengths carrying differing content are
Inside the transmitter, multiple optical wavelengths carrying differing content are
multiplexed for transport on a common fiber. The transmitter output is then
demultiplexed to feed segmented service areas.
The transmitter is designed to operate over a wide range of optical output powers
The transmitter is designed to operate over a wide range of optical output powers
and loss budgets, delivering both analog and digital signals. Microprocessor control
allows for ease of installation and flexibility of application.
High Density Transmitter Features
The high density transmitter has the following features.
Front panel green light emitting diode (LED) to indicate operating status
Front panel red LED to indicate alarm status
-20 dB front panel test point
Optical input connectors
Plug-and-play capability
Compatible with Intelligent Communications Interface Module (ICIM), Local
Craft Interface (LCI) software, and Transmission Network Control System
(TNCS) software
Blind-mate radio frequency (RF) connections
High Density Transmitter Operation
The Prisma II High Density Transmitter receives an RF signal through a connector
on the back of the module. The RF input signal is amplified before being converted
to an optical signal using a high-performance, isolated distributed feedback (DFB)
laser.
The incoming RF signal is also routed through a coupler to an RF detector circuit.
The incoming RF signal is also routed through a coupler to an RF detector circuit.
The RF detector produces a DC voltage proportional to incident RF power that is
used to monitor the input power level. The transmitter generates an alarm condition
if input power rises above or falls below a specified level.
