| PGR 203 12 APD Receiver Module up to 3 Gb/s Key Features * Hermetic, 14 pin butterfly package with multisourced footprint * FC/PC, SC or ST connector * InGaAs APD with low noise GaAs MMIC preamplifier * AC-coupled, differential data output * Operates between 1250 nm and 1620 nm * 2.0 GHz minimum bandwidth * -34 dBm typical sensitivity * -3 dBm typical overload Applications * WDM * SDH STM-16 LH * SONET OC-48 LR * Digital recievers to 3 Gb/s * Analog receivers to 2.0 GHz Description Fiber optic receiver front-end module for STM-16 and OC-48 WDM applications. The module includes an InGaAs Avalanche Photo Diode (APD), with a low noise GaAs MMIC preamplifier in a 14 pin butterfly package.The module is equipped with an internal thermistor. The single-mode fiber pigtail is terminated with a customer specified connector. The module operates between 1250 and 1620 nm. The electrical outputs are AC-coupled and differential. 1 PGR 203 12 FIBER DATA APD PREAMP DATA_NOT Figure 1. Block diagram Pin connection 1. 2. 3. 4. 5. 6. 7. 8.

This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. 3 PGR 203 12 Handling Precautions This device may be damaged as a result of electrostatic discharge (ESD). Take proper precautions during both handling and testing. This typically includes grounded wrist wraps, workbenches and floor mats in ESD controlled areas. Semiconductor devices may be damaged by current surges, use appropriate transient protection. Quality Assurance Ericsson Microelectronics commitment to quality has been proven through a decade of semiconductor device production and has been confirmed to ISO 9001. Opto product qualification is made according to the intention of applicable Telcordia standards.
