/ ARY IN
This device consists of a PIN photodiode and a transimpedance amplifier assembled in a TO-46 package. It is designed for short-distance ATM up to 155 Mbps. The preamplifier's linearity and absence of automatic gain control makes it ideal also for analog applications and applications with bursty signals. Its double-lens optical system is designed for single-mode fiber as well as for multimode fiber with core diameter up to 62.5µm.

PRODUCT INFORMATION ST 2A Package
Emitter or Detector in ST ® Package
Mitel emitters and detectors can be p r o v i d e d in this low-profile ST ® package. The device is electrically isolated from the ST ® receptacle to facilitate electrical connection. And o p t i m u m fiber-coupled power or r e s p o n s i v i t y is ensured by active alignment against the fiber.
