coaxial module and integrated circuits for reshaping,
retiming and regenerating optical signal.
FEATURES

leach application fully line up
Low cost and Low power consumption
Multisourced 20-Pin DIP with pigtail fiber
Single +5V power supply and P-ECL compatible
input and output
Operating case temperature range -40 to 85
°
C
With clock recovery and digital alarm function
APPLICATION
Short haul and long haul telecommunication systems
for SDH STM-1 / SONET OC-3.
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.

Pin description
These pin are the module’s ground connections.
They should be connected to a low inpedance ground plane(0V).
This is the power supply pin for the module.
It should be connected to +5.0V.
Recommended power supply decoupling.
This data input pin modulates the laser diode. When the Data input is
asserted,the laser diode is turned on.
Signal level of these pin are PECL level and internal Vbb bias. Refer to
electrical interface in NOTE1.
The transmitter is nomally enabled and only requires an external voltage
to disable.
Refer to electrical interface in NOTE2.
The laser bias current is calculated as a ratio of the voltage to an internal
10 ohm sensing resistor.
Ib[mA]={Lbs(+)-Lbs(-)}[mV]/10
Refer to electrical interface in NOTE3.
The laser backface monitor is calculated as a ratio of the voltage to an
internal 200 ohm sensing resistor.
Ibf[mA]={Lbf(+)-Lbf(-)}[mV]/200
Refer to electrical interface in NOTE3.
These pin are No user connection and should be left open.
