2040RDA-FR/16FR — Instruction Manual 47
Functional Description
Optical Input and Output Processing
The optical inputs to and outputs from the module are accessed through
the optional SFP (Small-form Factor Pluggable) submodule. The single
mode fiber optic submodule is available in two configurations: dual
receiver (2 inputs) or transceiver (1 input/1 output). Optical/electrical con-
version is done on the submodule. Inputs and outputs must be defined or
enabled by the user with the local jumper settings or using the web page
interface.
Microprocessor and Input Selector
The primary purpose of the microprocessor is to provide remote control
and monitoring capability for the 2040RDA-FR or 2040RDA-16FR. It
receives signal present, signal lock, and speed detection signals from the
equalizer and reclocker circuits. Using this information, local jumper set-
tings, and remote control commands, the microprocessor selects the
internal signal path and gives feedback through the LEDs and remote
control bus.
