Preliminary DATA SHEET FEATURES: 10Gbps 1310nm DML RWG DFB laser Very low power dissipation 50 Ohm impedance matching inside the laser package Differential electrical interface DFB LASER DIODE LC TOSA 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.

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 DFB-1310-10LR-LC ELECTRICAL-OPTICAL CHARACTERISTICS Unless otherwise stated, all parameters are at TCASE = 25C, TRANGE, CASE = -5 to 85C, 10.3125 Gbps, PRBS 231-1 Parameter Threshold Current Test Conditions Symbol T = 25C ITH Min.
