DFB-1310-10LR-LC
The DFB-1310-10LR-LC is specifically designed for applications based on
several optical communications standards, including IEEE 10GBASE-LR, STM64,
STM64 FEC, 10GFC, 10G GbE, 10G GbE FEC, & 10GFC FEC. Excellent optical
performance is achieved by matching the electrical characteristics of the TOSA
and laser to the external circuitry. Separate, differential laser bias and
modulation pins significantly reduce the amount of electrical power required at
the module level, and help to reduce the overall electro-magnetic emissions.
The TOSA is designed to be paired with the 10G LR ROSA PIN-1310-10LR-x
available at http://www.finisar.com/aoc.php.

NOTICE: Stresses greater than those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation
of the device at these or any other conditions above those
indicated in the operations section for extended periods of
time may affect reliability.
NOTICE: The inherent design of this component causes it
to be sensitive to electrostatic discharge (ESD). To prevent
ESD-induced damage and/or degradation to equipment, take
normal ESD precautions when handling this product

Notes:
1. Operating current is the average bias current required to meet the ER, rise/fall, and bandwidth specifications. The target
operating condition is 35 mA over threshold at high temperature, 30mA over threshold at RT.
2. Output power specification is defined into single-mode fiber(SMF 28).
3. TOSA would be capable of meeting other specifications when modulated over this ER range.
4. Maximum change in power as fiber is rotated by 360º.

5. SMSR is measured at Current => Ith + 8mA at -5C, 25C is Ith + 10mA and 85C Ith + 13mA
6. Measured with an optical receiver with a 10.7 Gb/s filter (4th order Bessel-Thomson filter with 3 dB bandwidth =
0.75*bitrate).
7. Includes the impedance matching network and the DFB intrinsic impedance
8. Tracking error is defined as the coupled power difference at Tmax or Tmin (relative to 25°C) where the back monitor current,
Imon, is held constant at the value found at 25°C at I=Iop.
