FRM5N142DS

APPLICATIONS

This 80GHz gain bandwidth product APD detector with HBT preamp

is intended to function as an optical receiver in 1,310nm and 1,550nm SONET, SDH

or the other optical fiber systems operating at 10Gb/s. The nominal 10k鈩?integral

thermistor allows accurate monitoring of the APD temperature and facilitates the design

of the APD bias control circuit. The typical transimpedance (Zt) value if 1000鈩?optimizes

the gain bandwidth for 10Gb/s application. The detector preamplifier is DC coupled

and has an electrical differential output.

DESCRIPTION

The FRM5N142DS incorporates a high bandwidth InGaAs APD photo diode, a GaAs

HBT IC amplifier in a hermetically sealed butterfly 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. It has differential output with DC coupling.
