Features Multisource compliant Data rates to 2.5 Gb/s SONET and ITU-T compliant at OC-48 and STM-16 Uncooled, field-proven InGaAsP MQW laser 1300 nm and 1500 nm versions Clocked or nonclocked operation with single-ended or differential inputs 50 ac-coupled ECL or PECL compatible data and clock inputs Operation from single +5 V or -5 V power supply Low-profile, 24-pin nonconductive package Automatic power control Wide operating case temperature range: -- T481, T483, -40 C to +85 C -- T485, -25 C to +70 C Laser back-facet monitor output Laser degrade alarm Transmitter-disable input FC, SC, LC, or MU connectors The T48-Type 2.5 Gb/s Laser Transmitters are designed for use in transmission systems and highspeed data communication applications. The transmitter operates at the SONET OC-48 rate, as well as the ITU-T SDH rate of STM-16. The transmitters meet all present Telcordia Technologies TM GR-253CORE requirements and the ITU-T G.957 and G.958 recommendations. They are also ideally suited for extended-distance data and networking applications. Manufactured in a 24-pin, plastic-encased DIP, the transmitter incorporates an InGaAs PIN photodiode back-facet monitor, a GaAs laser driver IC, and a choice of lasers, including: 1300 nm hermetic Fabry-Perot laser (T481 versions) 1300 nm hermetic MQW isolated DFB laser (T483 versions) 1550 nm hermetic MQW isolated DFB laser (T485 versions) The transmitter requires a single power supply (+5 V or -5 V). A clock input can be enabled for those applications where jitter is critical. Pin information is listed in Table 1. T48-Type 1300 nm and 1500 nm Uncooled 2.5 Gb/s Laser Transmitters Transmitter Processing Data Sheet, Rev. 1 February 2003 Table 1. Pin Descriptions The transmitter can withstand normal wave soldering processes. The complete transmitter module is not hermetically sealed; therefore, it should not be immersed in or sprayed with any cleaning solution or solvents. The process cap and fiber-pigtail jacket can deform at temperatures greater than 85 C. The transmitter pins can be wave-soldered at maximum temperature of 250 C for 10 seconds.

The optical connector should be kept free from dust, and the process cap should be kept in place as a dust cover when the device is not connected to a cable. If contamination is present on the optical connector, the use of canned air with an extension tube should remove any debris. Other cleaning procedures are identified in the Cleaning Fiber-Optic Assemblies Technical Note (TN95-010LWP). Connector Options The standard fiber-optic pigtail is an 8 m core singlemode fiber in a 0.036 in. (914 m) diameter, tight-buffered outer jacket. The standard length is 39 in. 4 in. (1 m 10 cm) and can be terminated with either an FC, SC, LC, or MU optical connector. Other connector options may be available on special order. * Laser back-facet and bias monitor functions are customer-use options that are not required for normal operations of the transmitter. They are normally used during manufacture and for diagnostics. Pins designated no user connection (NUC) cannot be tied to ground or any other circuit potential. Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

With VEE connected to -5 V, VCC must be at 0 V; with VCC connected to +5 V, VEE must be at 0 V. 2. Inputs are ac-coupled into an equivalent input impedance of 50 3/4. 3. Single-ended or differential operation may be used. If the inputs are driven single-ended, the unused inputs must be ac-coupled (0.1 F) to ground. 4. Clocked operation is optional. For clocked operation, pin 5 must be tied to VEE. With clocked operation, the optical output changes state with the rising edge of the input clock signal. If left unconnected, the pin will be pulled low, enabling the clock mode. 5.The transmitter is normally enabled and only requires an external voltage to disable. 6.This voltage is measured from pin 3 to VEE and is converted to laser bias current with the ratio of 20 mV/mA.

Optoelectronics modules are qualified to TriQuint's internal standards using MIL-STD-883 test methods and procedures and using sampling techniques consistent with Telcordia Technologies requirements. This qualification program fully meets the intent of Telcordia Technologies reliability practices TR-NWT-000468 and TA-TSY-000983. In addition, the TriQuint optoelectronics design, development, and manufacturing facility has been certified to be in full compliance with the latest ISO (R) 9001 Quality System Standards. 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). TriQuint Semiconductor 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 k, capacitance = 100 pF) is widely used and can be used for comparison purposes. Laser Safety Information Class I Laser Product FDA/CDRH Class I laser product.
