An optical connector for use with a light separator, the optical connector including a first portion and a second portion, the first portion being optically couplable by first optical transmitter to a first input of the light separator and by second optical transmitter to a second input of the light separator. The first and second portions are detachably couplable to couple the first and second optical transmitter to third and fourth optical transmitters, respectively, provided in or coupled to the second portion.
