Preliminary

DATA

SHEET

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.
