• Description: 155 Mb/s Single Mode Laser Transceiver For Atm, Sonet OC-3/SDH STM-1 (L1.1)
• Manufacturer: Agilent Technologies, Inc.

Connection Diagram
Pin Descriptions:
Pin 1 Receiver Signal Ground V
Directly connect this pin to the
receiver ground plane.
Pin 2 Receiver Data Out RD:
See recommended circuit
schematic, Figure 4.
Pin 3 Receiver Data Out Bar RD:
See recommended circuit
schematic, Figure 4.
Pin 4 Signal Detect SD:
Normal optical input levels to the
receiver result in a logic “1”
output.
Low optical input levels to the
receiver result in a fault condition
indicated by a logic “0” output.
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.

Mounting Studs
The mounting studs are provided
for mechanical attachment to the
circuit board. They are embedded
in the nonconductive plastic
housing and are not tied to the
transceiver internal circuit and
should be soldered into
plated-through holes on the
printed circuit board.
