Patent ID: 7039320

Claim:
A portable transceiver of one or more signals, comprising an input for receiving the one or more signals; a frequency modulator coupled with the input and modulating the one or more signals; a splitter coupled with the frequency modulator to divide the modulated signal into laser data signals; a plurality of lasers coupled with the splitter to receive the laser data signals, the lasers being displaced from one another and facing in parallel directions; the plurality of lasers including a laser driver coupled with the splitter and conditioning the laser data signals and laser diodes driven by the conditioned laser data signals, respectively; the laser driver including a modulation signal amplifier coupled with the splitter and a DC bias circuit coupled between the modulation signal amplifier and one of the laser diodes; and the laser driver further including a photodiode, a fiber optic element sampling the laser diode output and extending to the photodiode, the modulation signal amplifier being coupled with the photodiode and responsive to the output of the photodiode.
