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.
