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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Characteristics
1. Current gain of internal transformer.
2. Measured into 75
load.
3. Two laser test. Each laser has 40% modulation index. Total received optical power is 0 dBm.
