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.

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.
