• 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)
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 10KΩ 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.
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 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.
