MF-156DF-T12-20x/29x/23x
MF-156DS-R13-17x
SONET/SDH TRANSMITTER & RECIEVER
DESCRIPTION
This product is designed to provide high optical
performance for SDH STM-1/SONET OC-3.
Transmitter uses uncooled laser in a hermetic pigtail
coaxial module with drivered by specific integrated
circuit.
Receiver uses PIN preamp in a hermetic pigtail
coaxial module and integrated circuits for reshaping,
retiming and regenerating optical signal.
FEATURES
SONET,SDH system from intra-office to long-
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.

Data & Data
I
This data input pin modulates the laser diode. When the Dat a input is
asserted,the laser diode is turned on.
Signal level of these pin are PECL level and internal Vbb bias. Refer t o
electrical interface in NOTE1.
