Preliminary DATA SHEET FEATURES: Uncooled DFB laser diode 10km or 30km applications Pigtailed package with SC or FC connectors Packaged with monitor photodiode DFB LASER DIODE PIGTAILED PACKAGE DFB-1310-4X-50SMF-XXX The DFB-1310-4x-50SMF-XX are designed to meet the challenges of high speed data and telecommunications applications over distances up to 30km over single mode optical fiber. In addition, these lasers are ideal for analog applications such as CATV and other video networks. The lasers are mounted inside a metal coaxial package which is then pigtailed with a 50cm singlemode fiber and terminated with a fiber connector. The pigtail comes with a choice of either FC or SC connectors with an APC or UPC polish. The TOSA package includes a single stage optical isolator to minimize sensitivity to optical back reflections. Includes optical isolator Modulation speeds up to 4Gbps APPLICATION Source for high-speed data-communication and telecommunication links ♦ CATV, Satellite, and other analog fiber optic networks Part Number DFB-1310-4I-50SMF-FCUPC DFB-1310-4I-50SMF-FCAPC DFB-1310-4I-50SMF-SCUPC DFB-1310-4I-50SMF-SCAPC DFB-1310-4L-50SMF-FCUPC DFB-1310-4L-50SMF-FCAPC DFB-1310-4L-50SMF-SCUPC DFB-1310-4L-50SMF-SCAPC Description 10km 1310 nm DFB Laser Diode, 50cm singlemode pigtailed package, FC UPC connector. 10km 1310 nm DFB Laser Diode, 50cm singlemode pigtailed package, FC APC connector. 10km 1310 nm DFB Laser Diode, 50cm singlemode pigtailed package, SC UPC connector. 10km 1310 nm DFB Laser Diode, 50cm singlemode pigtailed package, SC APC connector. 30km 1310 nm DFB Laser Diode, 50cm singlemode pigtailed package, FC UPC connector. 30km 1310 nm DFB Laser Diode, 50cm singlemode pigtailed package, FC APC connector. 30km 1310 nm DFB Laser Diode, 50cm singlemode pigtailed package, SC UPC connector. 30km 1310 nm DFB Laser Diode, 50cm singlemode pigtailed package, SC APC connector.

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-1310-4X-50SMF-XXX ELECTRICAL-OPTICAL CHARACTERISTICS Unless otherwise stated, all parameters are at TCASE = 25°C, TRANGE, CASE = -40 to 85°C, 2.488 Gbps, PRBS 231-1 Parameter Threshold Current Test Conditions Symbol T = 25°C 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. Other output power range is possible per customer request. 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. Measured with an optical receiver with a 3.125 Gb/s filter 6. Rise and fall times are measured 20-80% 7. Resistance is measured between ITH + 10mA and ITH + 20mA 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.
