Digital video AdLib OCR Evaluation 1 .3 pm D2300-Type Digital Isolated DF13 Laser Module Description The D2300-Type Digital Isolated DFB Laser Module contains an internally cooled, InGaAsP, distributedfeedback (DFB) laser designed for 1 .3 pm applications . The laser is designed to be used in OC-12/STM-4 (622 Mbits/s) and OC-48/STM-16 (2.488 Gbits/s) for long-reach and extended-reach applications . The device is available with an average output power of 0 dBm (3 dBm peak), which meets the SONET/SDH standard. Controlled Feedback The module contains an internal optical isolator that suppresses optical feedback in laser-based, fiber-optic systems . Light reflected back to the laser is attenuated a minimum of 30 dB. Controlled Temperature An integral thermoelectric cooler (TEC) provides stable thermal characteristics. The TEC allows for heating and cooling of the laser chip to maintain a temperature of 25 C for case temperatures from -40 C to +75 C. The laser temperature is monitored by the internal thermistor, which can be used with external circuitry to control the laser chip temperature . Controlled Power An internal, InGaAs, PIN photodiode functions as the back-facet monitor. The photodiode monitors emission from the rear facet of the laser and, when used in conjunction with control circuitry, can control optical power launched into the fiber. Normally, this configuration is used in a feedback arrangement to maintain the average laser output power. Data Sheet, Rev. 1 December 2001 Optoelectronic components produced by Agere Systems Inc. are qualified to rigorous internal standards that are consistent with Telcordia Technologies TRNWT-000468 .

Handling Precautions Mounting Instructions Power Sequencing The minimum fiber bend radius is 1 .23 in. (31 .25 mm) . To avoid the possibility of damage to the laser module from power supply switching transients, follow this turnon sequence: 1 . All ground connections 2. Most negative supply 3. Most positive supply 4. All remaining connections Reverse the order for the proper turn-off sequence. Electrostatic Discharge CAUTION : This device is susceptible to damage as a result of electrostatic discharge . Take proper precautions during both handling and testing . Follow guidelines such as JEDEC Publication No. 108-A (Dec. 1988). Agere Systems employs a human-body model (HBM) for ESD-susceptibility testing and protection-design evaluation. ESD voltage thresholds are dependent on the critical parameters used to define the model . A standard HBM (resistance = 1 .5 ktl, capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes . The HBM ESD threshold presented here was obtained using these circuit parameters: Parameter Value Unit Human-body Model >400 V Agere Systems Inc. To avoid degradation in performance, mount the module on the board as follows : 1 .Place the bottom flange of the module on a flat heat sink at least 0.5 in. x 1 .180 in. (12 .7 mm x 30 mm) in size. The surface finish of the heat sink should be better than 32 pin. (0.8 pm), and the surface flatness must be better than 0.001 in. (25 .4 pm) . Using thermal conductive grease is optional ; however, thermal performance can be improved by up to 5% if conductive grease is applied between the bottom flange and the heat sink. 2.Mount four #2-56 screws with Fillister heads (M2-3 mm) at the four screw-hole locations (see Outline Diagram) . The Fillister head diameter must not exceed 0.140 in. (3.55 mm) . Do not apply more than 1 in.-Ib. of torque to the screws . r 0.118 (3 .00) 0.062 (1 .58) 0.086 (2 .18) 0.031 (0 .79) 0.140 (3 .56) i ~ I ~~ I ~0 .129(3 .28)R 0.041 (1 .04) 1-532 Note: Dimensions are in inches and (millimeters) .
