2606B Return-Path Photodiode Receiver Module
Description
The 2606B CATV return-path photodiode module is a
critical component for the delivery of high-perfor-
mance interactive services for today's two-way fiber-
optic networks. These modules utilize PIN InGaAs
photodiodes in robust 14-pin DIL packages that
exhibit excellent sensitivity, low noise, and excep-
tional linearity in return-path optical links. The mod-
ule incorporates a patented impedance-matching
circuit, which optimizes very low noise gain in optical
broadband receivers.
