Data Sheet August 2000 2606B Return-Path Photodiode Receiver Module Description The 2606B CATV return-path photodiode module is a critical component for the delivery of high-performance interactive services for today's two-way fiberoptic networks. These modules utilize PIN InGaAs photodiodes in robust 14-pin DIL packages that exhibit excellent sensitivity, low noise, and exceptional linearity in return-path optical links. The module incorporates a patented impedance-matching circuit, which optimizes very low noise gain in optical broadband receivers. Pin Information Features ■ 5 MHz—200 MHz frequency range ■ Flat response to ± 0.5 dB ■ High optical responsivity ■ Ultra low optical return loss ■ 75 Ω impedance-matched Applications ■ Return-path CATV receivers Table 1.
