Video surveillance CATV Wireless/personal communications networks and systems A2300-Type Laser 2000 Analog DFB Laser Module Description The Laser 2000, A2300-Type Analog DFB Laser Module contains a high-performance, Indium Gallium Arsenide Phosphide, multiquantum-well, distributedfeedback laser chip designed for 1310 nm, single-mode fiber-optic applications. The module is an industrystandard, 14-pin butterfly-type, hermetic, metal/ceramic package and houses the laser chip as well as an integral thermoelectric cooling/heating device, a thermistor, an integral optical isolator, and a laser backfacet optical monitor. The module is equipped with a 900 m Hytrel* jacketed, 8.8 m core, single-mode fiber; several standard fiber-optic connector options are also available. The integral thermoelectric cooler (TEC) provides stable thermal characteristics for the laser chip, as well as the optical isolator and back-facet monitor photodiode. The TEC allows for heating and cooling of these internal optical components and can maintain their temperature at a constant 25 C over the entire ambient operating temperature range of -20 C to +65 C. The thermistor monitors the internal module temperature and provides feedback control for the TEC. This gives the A2300-type laser 2000 superior, stable optical characteristics. When used in a fiber-optic system, reflected light entering the laser module is attenuated a minimum of 40 dB by the optical isolator. The internal PIN photodiode monitors the optical power emitted from the rear facet of the laser diode, and when used in conjunction with exterior module circuitry, it can monitor and control the optical output power launched into the fiber. Data Sheet August 2000 RF transformer internal to the package. This allows the RF drive level into the laser to be typically 4 dB less than if resistive matching were used. The second pinout type has a resistive input impedance of 25 and matches the pinout of the optoelectronic industry's standard 2.5 Gbits/s package. Lucent Technologies analog laser modules feature the ability to have enhanced performance and value through the addition of the Optoelectronics unit's exclusive predistortion board. The separate predistortion board provides both CSO and CTB correction enhancements to the laser module performance, for 110 NTSC as well as 42 CENELEC channels. While maintaining extremely low electrical power dissipation and low insertion loss, the predistortion board allows 1000 MHz of RF bandwidth. Every A2300-type laser 2000 module is tested to meet the customer's analog performance specifications, over the specified fiber link budget loss and test channel plan. This measurement method ensures proper system performance of the product. Lucent Technologies Optoelectronics unit components and products are qualified to the rigorous requirements of Telcordia Technologies Standards, ensuring that the optoelectronic performance will meet the needs of the application over the lifetime of the product. * Hytrel is a registered trademark of E.I.

Lucent Technologies Inc. A2300-Type Laser 2000 Analog DFB Laser Module Data Sheet August 2000 Handling Precautions Power Sequencing Mounting Instructions for Laser Module Adopt the following sequence for turn-on as a matter of good practice to avoid the possibility of damage to the laser module from power supply switching transients. The minimum fiber bend radius is 1.25 in. 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 in. (0.8 m), and the surface flatness must be better than 0.001 in. (25.4 m). The use of 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) (see Figure 4) at the four screw-hole locations (see Outline Diagram, page 7). The Fillister head diameter must not exceed 0.140 in. (3.55 mm). Do not apply more than 1 in.-lb. of torque to the screws. 0.118 (3.00) 0.062 (1.58) 0.140 (3.56) 0.129 (3.28) R 0.041 (1.04) 2. Most negative supply. 3. Most positive supply. 4. All remaining connections. Reverse the above 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). Lucent employs a human-body model (HBM) for ESDsusceptibility 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 k, 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: 0.086 (2.18) 0.031 (0.79) 1.
