FRM5W232BS

Features:

• 2.5Gb/s APD Receiver module in an industry standard mini-DIL package
• High Sensitivity: -34 dBm (typ.)
• High Differential Electrical Output
• Power Overload: -4dBm (typ.)
• Integral Thermistor and GaAs IC Preamp
• Wide operating temperature range (-40 to +85°C)


Application

This APD detector preamp is intended to function as an optical receiver in long haul SONET, SDH, and DWDM systems operating up to 2.7Gb/s. The device operates in both the 1,310 and 1,550nm wavelength windows. The nominal 10K integral thermistor allows accurate monitoring of the APD temperature and facilitates the design of the APD bias control circuits.

The detector preamplifier is DC coupled and has a differential electrical output.

Description

The FRM5W232BS incorporates a 30 micron InGaAs Avalanche Photodiode (APD) detector, a GaAs IC transimpedance preamplifier, and a thermistor in a mini-DIL type package. The APD is processed with modern MOVPE techniques resulting in reliable performance over a wide range of operating conditions. The lens of FRM5W232BS coupling system and the single mode fiber are assembled using Nd: YAG welding techniques. The BS package is designed for a surface mount PC board assembly.
