The second coherent optics transceiver is configured to (i) receive the downstream optical signal, and (ii) simultaneously transmit the upstream optical signal. The first wavelength has a first center frequency separated from a second center frequency of the second wavelength.

Systems and methods for achieving full duplex bidirectional transmission across coaxial cable in a hybrid fiber-coaxial cable TV network. Some preferred systems and method will attenuate reflections propagated within the coaxial cable. Other preferred systems may echo-cancel reflections propagated within the coaxial cable.

An optical line terminal (OLT) for an optical network configured to communicate with optical network units (ONUs) in a PON-type optical network, the OLT including: a processing circuitry, for each ONUs, to manage a transmission delay time in transmission to the ONU to manage an acceptable waiting time of uplink data of the ONU; to obtain an uplink transmission start time and data amount of the optical network unit, based on uplink assignment information; and to generate uplink transmission grant information, which is made up of a time point and time length of uplink transmission to the ONU, wherein the processing circuitry determines the uplink transmission grant information on transmission to the ONU, based on a transmission delay time of the ONU, on the uplink transmission start time and data amount of the ONU, and on the acceptable waiting time of uplink data of the ONU.

Estimating a lifespan of a power supply. An internal computerized component periodically obtains a set of measurements read from one or more sensors affixed to a power supply. Such measurements may measure ambient temperature, temperature of an electrolytic capacitor of a power supply, voltage across a power supply, and/or current from the power supply. The internal computerized component analyzes the set of measurements using, at least in part, a weighted set of factors, to obtain an estimate of a lifespan of a power supply. The estimated lifespan may be sent over an optical link or wireless network to an entity monitoring the lifespan of the power supply.

A broadband access system, comprising a broadband access hub device (hub device) and broadband access premise devices (premise devices) wirelessly coupled the hub device to provide broadband services to multiple user equipment (UEs), is described. The hub device may access broadband services on a fiber optic broadband network and wirelessly provide access to the broadband services to the premise devices. The premise device may wirelessly communicate with the hub device and communicate with user equipment (UEs) for providing access to the broadband services through the hub device.
