Novel tools and techniques are provided for implementing visual impairment detection for free-space optical communication ('FSOC') systems. In various embodiments, a computing system might receive, either from a camera or from a database, images (and/or videos) of an optical field of view ('FOV') of the camera, the optical FOV comprising an optical beam(s) of a first FSOC system; might autonomously analyze the captured images (and/or videos) to determine whether an object(s) is moving within proximity to an optical beam(s) of the first FSOC system, to perform at least one of reactive learning or proactive learning regarding potential interruption of the optical beam(s) of the first FSOC system, and/or to determine one or more preventative measures to prevent interruption of the optical beam(s) of the first FSOC system; and might autonomously initiate one or more first tasks and/or the one or more preventative measures, based on the analysis.

Visual impairment detector for free-space optical communication systems

Methods of operating an optical communication system in coherent optical transmissions for metro applications. Relative to conventional solutions, the optical communication system can be implemented with reduced cost and can operate with reduced power consumption, while maintaining high data rate performance (e.g., 100G). Furthermore, a programmable transceiver enables compatibility with a range of different types of optical networks having varying performance and power tradeoffs. In one embodiment, the optical communication system uses 100 Gb/s dual-polarization 16-point quadrature amplitude modulation (DP-16QAM) with non-linear pre-compensation of Indium Phosphide (InP) optics for low power consumption.

Coherent optical transceiver with programmable application modes

A timing recovery system generates a sampling clock to synchronize sampling of a receiver to a symbol rate of an incoming signal. The input signal is received over an optical communication channel. The receiver generates a timing matrix representing coefficients of a timing tone detected in the input signal. The timing tone representing frequency and phase of a symbol clock of the input signal and has a non-zero timing tone energy. The receiver computes a rotation control signal based on the timing matrix that represents an amount of accumulated phase shift in the input signal relative to the sampling clock. A numerically controlled oscillator is controlled to adjust at least one of the phase and frequency of the sampling clock based on the rotation control signal.

Timing recovery for optical coherent receivers in the presence of polarization mode dispersion

A coherent receiver comprises an ingress signal path having an ingress line-side interface, and an ingress host-side interface. The ingress signal path is configured to receive an analog signal vector at the ingress line-side interface, to demodulate the analog signal vector, and to output a digital data signal Fat the ingress host-side interface. The coherent receiver also comprises clock and timing circuitry configured to receive a single reference clock signal and to provide a plurality of modified ingress path clock signals to different components of the ingress signal path, the plurality of modified ingress path clock signals derived from the single reference clock signal and the plurality of modified ingress path clock signals having different clock rates. The receiver, transmitter, or transceiver can operate in a plurality of programmable operating modes to accommodate different modulation/de-modulation schemes, error correction code schemes, framing/mapping protocols, or other programmable features.

A transceiver for fiber optic communications. The transceiver can include a transmitter module having a transmitter host interface configured to receive an input host signal; a transmitter framer configured to frame the input host signal and to generate a framed host signal; and a transmitter coder configured to encode the framed host signal to generate an encoded host signal for transmission over a communication channel. The transceiver can also include a receiver module having a bulk chromatic dispersion, fiber length estimation, and coarse carrier recovery circuit configured to equalize a digital input ingress signal to generate an equalized ingress signal; a receiver framer configured to frame the equalized ingress signal to generate a framed ingress signal; and a receiver host interface configured to output the framed ingress signal. The receiver host interface is compatible with a framing protocol of the receiver framer.
