Abstract
A receptacle-collimator assembly and a multi-wavelength optical receiver module. The receptacle-collimator assembly includes a receptacle configured to receive a wavelength-multiplexed optical signal; and a collimator integrated with the receptacle and configured to generate a collimated beam signal from a multi-wavelength optical signal received from the receptacle and output the beam signal.
Claims3
A receptacle-collimator assembly comprising:
- a receptacle configured to receive a wavelength-multiplexed optical signal;
- and
- a collimator integrated with the receptacle and configured to generate a collimated beam signal from a multi-wavelength optical signal received from the receptacle and output the beam signal,
- wherein the collimator comprises:
- a sleeve;
- and a collimating lens with the same external diameter as a fiber stub of the receptacle, the collimating lens being inserted into the sleeve and comprising a projection protruding outward from a front edge thereof to come in contact with the fiber stub, and a remaining portion other than the projection being spaced apart from the fiber stub.
