1A277A

High-Performance LED

FM and Baseband Video

The low harmonic distortion and low thermal droop makes this device ideal for subcarrier FM and baseband video applications. Video transmission can be accomplished with minimum 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.
