optical Communications Return Path Analog CATV Detector Modules EPM 705 Series Key Features * Electro-optical - Low intermodulation distortion - High responsivity - Low back reflection * Packaging - Single mode 900 m fiber with or without a connector - Single mode 250 m fiber without a connector Applications * AM fiber optic CATV receivers to 550 MHz (EPM 705) * Multi-channel fiber optic transmission The EPM 705 series are high quality analog photodetectors designed for return path 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 705 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. north america : 800 498-JDSU (5378) worldwide : +800 5378-JDSU website : www.jdsu.com Return Path Analog CATV Detector Modules 2 Dimensions Diagram EPM 705 with Dual Mount Bracket (Specifications in mm unless otherwise noted.)

Use of grounding straps, anti-static mats, and other standard ESD protective equipment is recommended when handling or testing an InGaAs PIN or any other junction photodiode. Soldering temperature of the leads should not exceed 260 C for more than 10 seconds. Fiber pigtails should be handled with less than 10 N pull and with a bending radius greater than 1 inch. north america : 800 498-JDSU (5378) worldwide : +800 5378-JDSU website : www.jdsu.com Product specifications and descriptions in this document subject to change without notice.
