Abstract:
1. A bidirectional ‘transmit’ optical subassembly (“TOSA”) in an optical transceiver that automatically adjusts to maintain an integrity of a data link, the bidirectional TOSA comprising: a transmitter module for transmitting a first data signal at a first wavelength of light through an optical fiber connected with the TOSA; a receiver module included with the transmitter module for receiving a second data signal through the optical fiber, the second data signal including diagnostic data and being transmitted at a second wavelength of light; a diagnostic module communicatively coupled with the transmitter module and the receiving module, the diagnostic module using at least the diagnostic data in the second data signal to adjust at least one of a power, a wavelength, and a modulation of the first data signal; an echo cancellation device; and a beam splitter communicatively coupled to the transmitter module, the receiver module, and the optical fiber, the beam splitter being configured to be reflective with respect to the first wavelength and transmissive with respect to the second wavelength or being configured to be reflective with respect to the second wavelength and transmissive with respect to the first wavelength, the reflectivity and transmittance of the beam splitter being configured to separate the first wavelength from the second wavelength such that the first data signal is transmitted from the transmitter module to the optical fiber and the second data signal received from the optical fiber is directed to the receiver module.
