Abstract:
1. A multiplexing device for multiplexing a plurality of channels, wherein each channel contains light within a range of wavelengths, the multiplexing device comprising: a housing; a printed circuit board; an electrical connector electrically coupled to the printed circuit board; a plurality of transmitters within the housing, each transmitter associated with one of the channels, wherein each transmitter provides a beam containing the associated channel; each of the transmitters having electrical leads mounted to the printed circuit board; a plurality of filters, each filter associated with one of the channels, wherein each filter is transverse to the beam containing the associated channel and is configured to select a range of wavelengths which includes the associated channel; the housing having a front surface substantially perpendicular to the printed circuit board; an output collimator configured to receive the channels after the channels are selected by the associated filters and to provide an optical path for outputting the multiplexed channels through the front surface of the housing.
