A fiber storage unit, including a base, a ring adapted to rotate relative to the base and a fiber fixedly attached at a first point to the base and at a second point to the ring. The fiber is attached in a manner that the fiber portion between the first and second points is arranged as a spiral which changes its number of rounds when the ring is rotated relative to the base, but the fiber portion beyond the first point is not substantially twisted by rotation of the ring. The fiber preserves a bending radius above a critical bending radius of the fiber.

Handling excess optical fiber

Communication apparatus, comprising: a network of power lines; and first, second and third transceivers, coupled to the network, the first transceiver being adapted to transmit a first signal over the network to the second transceiver within a selected frequency band at a transmission power level sufficiently strong that the first signal can be decoded by the second transceiver, but is attenuated sufficiently when it reaches the third transceiver so that the third transceiver can receive a second signal over the network in the selected frequency band substantially without interference by the first signal.

Power line communication system

A method of connecting a power line modem to an external network. The method includes receiving, by the power line modem, a plurality of packets directly transmitted from a plurality of neighboring devices connected to the power lines, determining for each of the plurality of neighboring devices, a cost of a route to an access unit, through the neighboring device, responsive to the received packets, and selecting an access unit to service the power line modem, responsive to the determination of the costs.

Dynamic power line access connection

A method for communication over a network of power lines (), including establishing a communication link within a selected frequency band over the network between a first transceiver (B) coupled to the network and a second transceiver (C) coupled to the network. The method further includes transmitting a first signal over the link from the first transceiver to the second transceiver at a transmission power level that is sufficiently strong that the signal can be decoded by the second transceiver, but is attenuated sufficiently when it reaches a third transceiver (E) coupled to the network so that the third transceiver can receive a second signal over the network in the selected frequency band substantially without interference by the first signal.

A method of transmitting data over lines of power line network comprising: inductively generating opposite polarity currents representing the data on first and second lines of a pair of lines of the network at a first location along the lines that propagate along the lines; and sensing the propagated currents at a second location along the lines.
