Abstract
A high dynamic range integrated (HDRI) receiver includes a variable optical attenuator (VOA) for attenuating an incoming optical signal before the optical signal is directed to a photo-detector for conversion into an electrical signal. An optical block receives the optical signal from an optical fiber and includes optics for directing the optical signal to the VOA, and for directing the optical signal from the VOA to the photo-detector.
Claims18
A receiver optical subassembly (ROSA) comprising:
- an input port for receiving an end of an optical waveguide, which launches an optical beam having a light intensity and including an optical signal;
- a variable optical attenuator (VOA) mechanism for attenuating the light intensity of the optical beam;
- a photo-detector for converting the optical signal into an electrical signal;
- and
- optical coupling means comprising an optical block for receiving the optical beam from the optical waveguide through a first input surface, wherein the optical block includes optics for directing the optical beam to the VOA mechanism, for receiving the optical beam from the VOA mechanism through a second input surface, and for directing the optical beam to the photo-detector.
