Abstract
An optical transmitter (1) comprises a semiconductor laser optical source (14) housed in an optical fibre connector component. An optical baffle (8) such as a short section of optical fibre ensures that only minimal power is emitted to the environment when the transmission fibre (6) is withdrawn from the connector.
Claims15
An optical device comprising:
- a housing;
- an optical source positioned within the housing;
- a first ferrule for receiving an end of an optical transmission waveguide;
- a second ferrule having an optical baffle disposed therein;
- a third ferrule inserted in the housing for receiving at least a portion of the second ferrule and at least a portion of the first ferrule, whereby the second ferrule is disposed between the optical source and the first ferrule whereby the source, the optical baffle, and the optical transmission waveguide are optically aligned within the housing, the first ferrule and the second ferrule having substantially the same external diameters.
