part of the Prisma II optical network, an advanced transmission system
designed to optimize network architectures and increase reliability,
scalability, and cost effectiveness.
The transmitters install 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.
The transmitters are designed to operate over a wide range of loss budgets
and digital signal loads. Microprocessor control allows ease of installation
and flexibility of application.
The transmitter design includes an array of capabilities, such as low RF input
level, broadcast, and elective Automatic Gain Control (AGC).
Features
The high density transmitter has the following features:
Operation
¾ Front panel green light emitting diode (LED) to indicate operating status
¾ Front panel red LED to indicate alarm status
¾ -20 dB test point
¾ Optical output connector
¾ Plug-and-play capability
¾ Compatible with Intelligent Communications Interface Module (ICIM) and Local
Craft Interface (LCI) software
¾ Blind-mate radio frequency (RF) connections
The transmitter receives an RF signal through a connector on the rear of the
module. The RF input signal is amplified and converted to an optical signal.
This module employs an Indium Phosphide-based hybrid laser/modulator
structure to both generate the optical carrier and modulate this optical carrier
with the input RF signal.
The incoming RF signal is amplified and then routed through a coupler to an
RF detector circuit. The detector circuit produces a DC voltage proportional

to the incident RF power. A controller monitors this voltage level to evaluate

system is active. Even if the unit is off, there may still be hazardous optical
levels present.
the input power level. The transmitter generates an alarm condition if the
input power is over or under a specified level.
The amplified RF signal is also routed to a variable attenuator, which is used
to reduce RF power in an overdrive condition or compensate for gain
variations in the transmitter. The signal is equalized, impedance-matched,
and then sent to the laser. The optical output connector is located on the front
panel of the module.
Transmitter gain is controlled through the selection of Manual or Automatic
Gain Control (AGC) mode operation.
¾ In Manual mode, an attenuator can be used to reduce RF power in an overdrive
condition or to compensate for variations in transmitter gain. Any manual
attenuator adjustments are reflected in the indicated RF drive level. It may be
desirable to make such adjustments to compensate for power differences if the
channel load differs from the specified value.
¾ In AGC mode, the microprocessor monitors the actual input composite power
and adjusts the attenuator to maintain constant RF drive level into the laser
diode.
After the RF amplification and control stage, the signal is equalized and
impedance-matched, and then is sent to the hybrid laser/modulator. The
optical output connector is located on the front panel of the module.
The user can turn the laser on or off, adjust the drive level to the laser, and set
alarm levels. The module can be controlled either locally using LCI, the ICIM
front-panel interface, or remotely using CLI commands or the ICIM Web
Interface.
Optical Output
The optical output connectors are SC/APC.
