COMMUNICATIONS COMPONENTS

Key Features

• Electro-optical

- Low intermodulation distortion

- High responsivity

- Low back reflection

• Packaging

- Single mode 900 µm fiber with or without a connector

- Single mode 250 µm fiber without a connector

The EPM 7xx series are high quality analog photodetectors designed for forward

path (EPM 745) and return path (EPM 705) AM CATV applications. These

coaxial modules are optically aligned to optimize performance and balance the

parameters of responsivity, distortion and back reflection.

The photodetector die is fabricated with a proprietary InGaAs process in our

wafer fab and assembled into a hermetically-sealed package with an antireflective-

coated lens. A stainless steel bushing is used to actively couple the fiber to the package.

The fiber is reinforced with a rubber boot which relieves fiber bending stresses.

The EPM 7xx series can be produced without a connector or with a variety of

industry standard connectors. They are also available with a mounting bracket

which allows both vertical panel mounting and horizontal flush-to-board mounting.

Applications
