Abstract
An optical transceiver device including a modulating assembly. In contrast with conventional transceivers, the optical transceiver device uses a modulating assembly rather than a laser. The modulating assembly is located within the transceiver itself and includes first and second collimating lenses, first and second mirrors, and a p-i-n diode. An optical signal that has not yet been modulated is introduced into the modulating assembly via the first collimating lens, and is redirected toward the p-i-n diode via the first mirror. Depending on the voltage state of the diode, the light signal is either transmitted through the diode or prevented from passing, which results in modulation of the signal for data transmission. The modulated signal passes through the modulating assembly and is reflected by the second mirror toward the second collimating lens, through which it passes before exiting the transceiver.
