50 Ohm impedance matching
Differential electrical interface Anti-wiggle receptacle APPLICATION Designed for SONET and Gigabit Ethernet ♦ Compatible with all 10Gb MSAs (XFP , X2, XPAK, XENPAK) DFB LASER DIODE LC TOSA DFB-1310-10LR-LC 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. Part Number Description DFB-1310-10LR-LC 10Gb DFB laser in LC TOSA
DFB-1310-10LR-LC DFB LC LASER DIODE 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 ABSOLUTE MAXIMUM RATINGS Parameter Rating Storage Temperature -40°C to +85°C Case Operating Temperature -5°C to +85°C Lead Solder Temperature 260°C, 10 seconds Continuous Optical Power 20mW Liode Diode Reverse Voltage 2V Laser Diode Continuous Forward Current 130mA Monitor Photodiode Reverse Current 2mA Monitor Photodiode Reverse Voltage 10V

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. Continued....
