Abstract: A system configured to maintain a consistent local-oscillator-power-to-primary-signal-power ratio (LO/SIG ratio). The system may be configured to: receive the voltages for a plurality of optical signal components split from a combined SIG and LO signal; determine individual factors for the plurality of optical signal components; average the individual factors; determine whether the averaged output is less than an existing minimum reference value for a variable optical attenuator; determine whether the averaged output is greater than an existing maximum reference value for the variable optical attenuator; change the existing minimum reference value to a new value associated with the averaged output, due to determining that the averaged output is less than the existing minimum reference value; change the existing maximum reference value to a new value associated with the averaged output, due to determining that the averaged output is greater than the existing maximum reference value; and change a new value associated with the averaged output to be transmitted to the variable optical attenuator.

Abstract: One or more operational parameters associated with pluggable optical transceivers are estimated to mitigate impairments to an optical signal caused by imperfections in the optical transceivers. A monitoring algorithm within a receiver signal processor may further use the estimated operational parameters associated with the pluggable optical transceivers to determine whether the transceivers are performing correctly. If the monitoring algorithm determines that either the transmitting or receiving optical transceiver is not functioning correctly, it may generate an alarm signal to notify a system administrator about the damaged device.

Abstract: A method for encoding bits according to a convolutional code. Bits to be encoded with the convolutional code are obtained for transmission over a communication channel. The bits are encoded according to the convolutional code with an encoder having an M-bit memory and a plurality of logic gates so as to separate trellis segments of the convolutional code into trellis sub-segments having a reduced number of branches per state than that of the trellis segments.
