| Preliminary DATA SHEET DFB LASER DIODE LC TOSA DFB-1310-10LR-LC FEATURES: 10Gbps 1310nm DML RWG DFB laser Very low power dissipation 50 Ohm impedance matching inside the laser package Differential electrical interface Anti-wiggle receptacle 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. APPLICATION Designed for SONET and Gigabit Ethernet Compatible with all 10Gb MSAs (XFP, X2, XPAK, XENPAK) Part Number DFB-1310-10LR-LC Description 10Gb DFB laser in LC TOSA DFB-1310-10LR-LC DFB LC LASER DIODE ABSOLUTE MAXIMUM RATINGS Parameter Storage Temperature Case Operating Temperature Lead Solder Temperature Continuous Optical Power Liode Diode Reverse Voltage Laser Diode Continuous Forward Current Monitor Photodiode Reverse Current Monitor Photodiode Reverse Voltage Rating -40C to +85C -5C to +85C 260C, 10 seconds 20mW 2V 130mA 2mA 10V 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 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 Operating Current Modulation Current Output Power Slope Efficiency Extinction Ratio LA (wiggle) Wavelength Spectral Width (-20dB) Wavelength temperature coefficient Side Mode Suppression Transmitter Reflectance Mask Margin Rise / Fall Time Forward Voltage TOSA Input Resistance Monitor Current Power Tracking Error Monitor Dark Current Monitor Diode Capacitance Optical Return Loss Tolerance Differential Return Loss Case to Signal Isolation Test Conditions T = 25C T = TRANGE T = 25C T = TRANGE T = 25C T = TRANGE IF = IOP T = 25C, SMF T = TRANGE Symbol ITH IOP IMOD LOP Min.

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 360. Continued....
