A data transceiver employing optical radiation comprises transmitter assembly with an optical emitter operable in a first band and an optical emitter in a second band and a receiver assembly with a wide band optical detector which can receive signals transmitted via both the first and second band. In a second embodiment, the receiver includes both a wide band optical detector and a second optical detector which is operable in only one of the first and second bands, the receiver subtracting signals received at the second optical detector from those received at the wide band detector to separate signals received via the first and second bands. In a preferred aspect, the optical radiation employed is infrared radiation and the first and second bands are near and medium infrared bands.
An infrared data transceiver comprising:
An infrared data transceiver according to claim I further including a second IR detector, said second IR detector having a nominal spectral response of between about 850 nm to about 950 nm and wherein said receiver assembly is responsive to at least one of a first signal received by said first IR detector and a second signal obtained by subtracting any signal received by said second IR detector from a signal received by said first IR detector.
An optical data transceiver comprising:
A data transceiver employing optical radiation to transmit and receive data, comprising:
