10/155 Mb/s Single-Mode
OSC Laser, 1625 nm
Specifically designed for use as a low speed out of band
optical service channel for optical amplifiers. The laser is
available in a low-inductance 14-pin butterfly package with
single-mode connectorized fiber-optic pigtail and has a
rated peak output power of 2mW. At 1625 nm, the LC162-20
does not interfere with WDM traffic in either the C or L band.
The high reliability buried hetro-structure DFB laser chip
ensures the reliability of the LC162-20 over the entire range
of recommended operating conditions.

Ordering Information
Please quote the Product Code from the table below when ordering
as this is the identification that appears on the part when shipped.
Instructions for Use
Pin 1 and Pin 2 Thermistor
The thermistor is used in a control loop
in conjunction with the thermo-electric
cooler to maintain the laser submount
temperature at the required value.
Operating current should be less than
100 A to prevent self-heating errors.
Pin 3 Laser modulation (-) and bias
The data input (modulation) and bias
are both applied via this pin which has
a nominal 25 Ohm load impedance.
Pin 4 Monitor anode, Pin 5 Monitor
cathode
The back facet monitor diode provides
a mean power reference for the laser
and is normally operated with a 5 V
reverse bias.
Pin 6 TEC (+), Pin 7 TEC (-)
Applying a positive voltage on pin 6
with respect to pin 7 will cause the
internal submount to be cooled relative
to the case temperature.
Reversing the polarity will raise
the submount temperature relative
to the case. Care should be taken
to avoid overheating the submount
when driving the TEC in this manner.
The TEC supply should be capable
of delivering up to 0.8 A and 2 V.
Pin 8, 9, 11, 13 Case ground.
These pins must be grounded
in all applications.
Pin 10, 14 N/C
These pins are not connected.
They should be grounded if possible.
Pin 12 Laser (+)
This pin provides the return path for
the laser modulation and bias circuits.
