SONET/SDH TRANSMITTER & RECIEVER
DESCRIPTION
This product is designed to provide high optical
performance for SDH STM-16/SONET OC-48.
Transmitter uses uncooled laser module with drivered
by specific integrated circuit.
Receiver uses PD or APD preamp-module and
integrated circuits for reshaping, retiming and
regenerating optical signal.
FEATURES
Full SONET/SDH line up
Low cost
Compact, low power
-5.2 V,+5V power supply, DC/DC converter built in
for Rx
Case Temp. Range: Class 1; -5 to +75°C / Class
2; -40 to +85°C
Clock recovery
Multi source
APPLICATION
Short haul and long haul telecommunication systems
for SDH STM-16 / SONET OC-48.
2.5Gb/s ATM LAN and ATM switching systems.
ABSOLUTE MAXIMUM RATINGS
Stress below listed absolute maximum rating may cause permanent damage to the module.
Th is is a stress o nly and functional operation of the module at these or any other conditions in excess of those
given in the operational sections of this data sheet .
Exposure to Absolute Maximum Rating for extended periods may affect module reliability.

*: The falling edge of Cki clock input signal is at the Di data eye pattern crossing point.
**: When open (or low) the module is in the operating mode. When high the module operates in non
clocked mode.
***: When high the module in the shut down mode (no optical output power).
When open (or low) the module is in the operating mode.
****: Vcc-Vee; with Vcc at +5V Vee must be at 0V; with Vee at -5.5V Vcc must be at 0V
*****: When provided a digital alarm indicates that the laser is degraded.
The active level is a low level.
This pin must be teidto Vcc through a 100k ohm resistor when the digital alarm is not proved

*: This pin is Not Internally Connected(NIC) in case of the high voltage generator is inside the module.
**: Package is at same potential as GND .
***: LPA output is a logic level that indicates the presence or absence of a sufficient optical input level.
A logical high level indicates an input optical level too low.
#: This pen is not internally connected if the amplitude decision threshold is not made adjustable.
##: This pen is not internally connected if the Optical Input Light Voltage functionality is not provided.
