Abstract
A system may include a first module at a far end, and an optical fiber coupled to the first module. The system may also include a second module at a near end that is configured to generate and transmit instructions to the first module to control operation of the first module.
Claims21
A system comprising:
- a first module at a far end;
- an optical fiber coupled to the first module at a first end of the optical fiber;
- a second module at a near end and coupled to a second end of the optical fiber, the second module configured to generate and transmit instructions to the first module to control operation of the first module.
A method, comprising:
- transmitting first instructions to a primary far end module to send diagnostic monitor data;
- receiving diagnostic monitor data from the primary far end module;
- determining whether the diagnostic monitor data is beyond a threshold;
- sending, based on the diagnostic monitor data being beyond the threshold, second instructions to the primary far end module to turn off a transmitter of the primary far end module;
- and
- sending, based on the diagnostic monitor data being beyond the threshold, third instructions to a secondary far end module to turn on a transmitter of the secondary far end module.

A method, comprising:
- establishing a receive chain using a forward error correction (FEC) chip;
- transmitting first instructions to a far end module to enable optical loop back of data received at the far end module;
- making a determination as to whether a bit error ratio (BER) based on the looped back data is within a threshold;
- sending second instructions to the far end module to adjust a receive decision threshold until the BER is within the threshold;
- and
- communicating, based on the BER being within the threshold, third instructions to the far end module to disable the optical loop back.
