COMMUNICATIONS COMPONENTS Forward and Return Path Analog CATV Detector Modules EPM 7xx Series 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 Applications • AM fiber optic CATV receivers to 550 MHz (EPM 705) and 860 MHz (EPM 745) • Multi-channel fiber optic transmission 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 antireflectivecoated 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.
