Patent ID: 8000607

Claim:
A an optical transceiver module that automatically adjusts to maintain an integrity of a data link, the optical transceiver comprising: a ‘transmit’ optical subassembly (“TOSA”) having: a primary transmitter module for transmitting a first data signal through a first optical fiber; a secondary receiver module included with the primary transmitter module for receiving a second data signal through the first optical fiber; and a first diagnostic module communicatively coupled with the primary transmitter module and the secondary receiver module, the first diagnostic module using at least a portion of the second data signal to adjust at least one of a power, a modulation and a wavelength of the first data signal; and a ‘receive’ optical subassembly (“ROSA”) having: a primary receiver module for receiving a third data signal through a second optical fiber; a secondary transmitter module included with the primary receiver module for transmitting a fourth data signal through the second optical fiber; and a second diagnostic module communicatively coupled with the primary receiver module and the secondary transmitter module, the second diagnostic module using at least a portion of the third data signal to generate at least a portion of the fourth data signal, the at least a portion of the fourth data signal containing diagnostic data about the first data signal.
