1. An optical or optoelectronic transceiver, comprising:
a connector configured to receive an optical fiber array;
a filter that is (i) configured to reflect first optical signals having a first wavelength and (ii) transparent to second optical signals having a second wavelength, wherein each of the first and second optical signals independently has an optical path to or from the optical fiber array;
a mirror in the optical path of the second optical signals, configured to reflect the second optical signals;
a plurality of photodiodes configured to receive a subset of the first and/or second optical signals and generate a corresponding plurality of received electrical signals therefrom; and
a plurality of laser diodes configured to transmit a remainder of the first and/or second optical signals from a corresponding plurality of transmitted electrical signals, wherein:
(i) a subset of the plurality of photodiodes is configured to receive a corresponding subset of the first optical signals, and a remainder of the plurality of photodiodes are configured to receive a corresponding subset of the second optical signals, and
(ii) a subset of the plurality of laser diodes is configured to transmit a remainder of the first optical signals, and a remainder of the plurality of laser diodes are configured to transmit a remainder of the second optical signals.
