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 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 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.

Precautions for Use

ESD protection is imperative. 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.
