Patent ID: 7401984

Claim:
An optical connector for use with a light separator, said optical connector comprising: a first portion and a second portion, said first portion being optically couplable by first optical transmitter to a first input of said light separator and by second optical transmitter to a second input of said light separator; wherein said first and second portions are detachably couplable to couple said first and second optical transmitters to respectively third and fourth optical transmitters provided in or coupled to said second portion, and wherein said first, second, third and fourth optical transmitters comprise first, second, third and fourth optical fibers respectively, said fourth optical fiber being multimode and having a greater diameter and many more guided modes than said second optical fiber; whereby said first and second inputs of said light separator can be optically coupled to a first optical instrument coupled to said third optical transmitter and a second optical instrument coupled to said fourth optical transmitter, and alignment of said second and said fourth optical fibers can be readily effected while achieving low loss.
