  • Patent number: 10560305
    Abstract: Approaches for compensating for RF imperfections in a system that comprises two or more independent modules. The two or more independent modules may be comprised within a remote PHY node (RPN). RF calibration data is stored in one or more non-volatile mediums for two or more independent modules. Each of the two or more independent modules are electronically coupled in a sequence via a transmission medium. A first independent module digital compensates a RF signal for a set of two or more modules that are coupled together in sequence via the transmission medium. The first independent module may correspond to a remote PHY device (RPD).

  • Patent number: 10505499
    Abstract: Configurable adjustment of a power amplifier bias for a power amplifier. The power amplifier may be comprised within a variety of different apparatuses, such as without limitation a remote PHY node, a remote MACPHY node, and a wireless communication device. A processing unit, disposed within an apparatus, instructs an electrical circuit, also disposed within said apparatus, to change an RF signal output power carrying capability of the power amplifier based on a configuration. The configuration may, but need not, be maintained within the apparatus. The change in the RF signal output power carrying capability of the power amplifier causes an adjustment in a power consumption of the power amplifier.

  • Patent number: 10419066
    Abstract: Approaches for supporting a RF automatic gain control (AGC) loop. A first module and a second module are coupled together via a single RF transmission cable. The first module might be a Remote PHY Device (RPD). The second module may comprise a power amplifier. Both the first and second module operate on a single automatic gain control (AGC) loop. The first module sends a first signal to the second module over the single RF transmission cable at a first frequency or frequency range. The first module may adjust a gain of the AGC loop based on a second signal sent from the second module to the first module over the single RF transmission cable. The second, counterpropagating signal has a different frequency or frequency range than the first frequency of the first signal, e.g., the second frequency or frequency range may be lower than that of the first frequency.

  • Patent number: 10404585
    Abstract: Segregating a node port experiencing ingress. A node that provides a service to a plurality of cable modems may have a plurality of node ports. The node may be a Remote PHY Node or a Remote MACPHY node. In response to detecting that a particular node port of the node is experiencing ingress, the assignment of node ports to upstream device ports are adjusted so that the particular node port experiencing ingress is not be assigned to the same upstream device port as any other node port. In further response to detecting ingress at the particular node port, all node ports assigned to the same upstream device port are caused to be assigned to the same downstream device port. By segregating the node port experiencing the ingress in this manner, the impact of that ingress can be mitigated or eliminated with respect to the other node ports of that node.

  • Patent number: 7342884
    Abstract: Optical transceivers used in data communications equipment are typically bidirectional and require two-way communications in order to maintain their operability. However, in some applications such as cable television, the traffic is highly unbalanced with very high bandwidth requirements in one direction and minimal bandwidth requirements in the opposite direction. Hence for such efficient and cost effective one-way communication applications, unidirectional fiber optic transceivers are useful. There is provided here a unidirectional transceiver provided internally with a keep-alive signal generator to enable unidirectional transmissions. The keep alive signal is, for instance, idle characters for a Gigabit Ethernet communication system, or any other suitable handshake signal which provides the desired operability.

  • Publication number: 20060203862
    Abstract: An optical transmitter for coarse wavelength division multiplexed (CWDM) optical communication systems uses a conventional laser (e.g. laser diode) and in addition a heater element is provided thermally coupled to the laser. A thermal sensor and associated control circuit drive the heater so as to control the power consumed by the heater to assure that the laser's temperature is not lower than a predetermined minimum working temperature. When the sensed laser temperature is above this predetermined minimum temperature, the control circuit turns off the heater. The total operating range of the transmitter in terms of ambient temperature is thus extended beyond its inherent operating range by the maximum laser temperature rise created by the heater. This allows a CWDM optical transmitter with the heater and control circuitry to be used in outdoor applications where a wide ambient temperature range is required.
