Abstract: Embodiments herein describe an intelligent optical cable that includes an optical assembly disposed between two pluggable connectors. In one embodiment, the optical assembly in the intelligent optical cable are coupled to the pluggable connectors via respective ribbons, where first ends of the ribbons are connected to the optical assembly while second ends of the ribbons are connected to respective pluggable connectors. In one embodiment, the optical assembly includes a photonic chip which performs an optical function on the optical signals propagating in the optical cable.

Abstract: The present disclosure provides signal management with unequal eye spacing by: determining a dispersion slope of a channel between a transmitter and a receiver based on a temperature of the transmitter and a wavelength used by the transmitter to transmit signals over the channel; determining maximum and minimum powers for transmission over the channel; assigning a plurality of rails to a corresponding plurality of power levels, wherein amplitude differences between adjacent rails of the plurality of rails are based on the dispersion slope and produce a first eye pattern with a first Ratio of Level Mismatch (RLM) less than one; encoding, by the transmitter, data onto a conditioned signal according to the plurality of rails; and transmitting the conditioned signal over the channel, so that the conditioned signal demonstrates a second eye pattern with a second RLM greater than the first RLM when received at the receiver.

Abstract: Hot pluggable or swappable devices that are easily removed and replaced by a network operator may be monitored for faults and utilized in post-deployment use. Device specific local monitoring and storing of operational parameters during a deployment of a device in a network is described. Additionally, utilizing the recorded operational parameters of device to generate baseline conditions for the device and individualized recommendations for the device is also described.

Abstract: Techniques for tuning an optical communication system are disclosed. The system includes a first signal path for transmitting data, including an optical source, a first one or more variable optical attenuators (VOAs), a modulator, and a transmission fiber. The system further includes a second signal path for receiving data, including a receiver fiber and a second one more VOAs. The first one or more VOAs are tuned using the optical source in the first signal path for transmitting data, based on comparing a plurality of optical signal power values in the first path while a first tuning mode is enabled. The second one or more VOAs are tuned, using the optical source in the first signal path for transmitting data, based on comparing a plurality of optical signal power values in the second path while a second tuning mode is enabled.
