Robust Small Package with Single-Mode

Fiber Pigtail and Connector Options

The 7830W CATV optical receiver is a single-mode fiber pigtailed module

featuring a low-noise, impedance-matched broadband photodiode and RF

amplification.

The device receives optical analog and/or digital signals for a range of video

broadcast options, and delivers the corresponding RF electrical output. The wide

bandwidth supports the delivery of signals up to 3GHz.

The 7830W exhibits good distortion performance with values well above

standards over the entire bandwidth with case temperature range from -40°C to

+85°C.

Moreover, the proprietary impedance-match circuitry between the photodetector

and RF amplification stages resolves a number of OEM design obstacles with

very low noise performance value.

The 7830W CATV optical receiver can be used in both 1310 nm and 1550 nm

applications being useful at different points of a given network.

The 7830W is compliant with all criteria of the Restriction of the Use of Hazardous

Substances in Electrical and Electronic Equipment (RoHS) guidelines

2002/95/EC.
