PRODUCT INFORMATION
870nm
1A184A
High-Performance LED
FM Video
The low harmonic distortion makes this device ideal for subcarrier FM video applications. Video transmission can be accomplished with minim u m distortion. The double-lens optical system provides for optimum coupling of power into the fiber.

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.
