Functional Description
nonconductive plastic housing and are not connected to the transceiver internal circuit, nor is there a guaranteed connection
Receiver Signal Ground
Directly connect this pin to receiver signal ground plane. (For AFBR-53B3, V
Receiver Data Out
RD+ is an open emitter output circuit. Termination is done externally to the module.
Receiver Data Out Bar
RD- is an open emitter output circuit. Termination is done externally to the module.
Normal optical input levels to the receiver result in a logic "1" output ,V
Low input optical levels to the receiver result in a fault condition indicated by a logic "0" output, V
Receiver Power Supply
Provide +5 V dc via the recommended receiver power supply filter circuit.
Locate the power supply filter circuit as close as possible to the V

Directly connect this pin to the transmitter signal ground plane.
The mounting pins are provided for transceiver mechanical attachment to the circuit board. They are embedded in the
to the housing. They should be soldered into plated-through holes on the printed circuit board.
Signal Detect
Signal Detect is a single-ended PECL output. SD can be terminated with standard PECL techniques via 50W to
compromise to signal integrity. If Signal Detect is not used, leave it open circuited.
This Signal Detect output can be used to drive a PECL input on an upstream circuit, such as, Signal Detect input
or Loss of Signal-bar.
