A shielded wire includes an electrical wire including a conductor portion and a covering portion, a shield braid in which electrically conductive wire members are braided, and which covers an outer circumference of the electrical wire, a tubular sheath disposed on an outer circumference of the shield braid and made of an insulating resin.

An Power over Ethernet (POE) which satisfies a Power-over-Ethernet plus (PoE+) power transmission characteristics and a data transmission rate of 1 Gigabits per second (Gbps) without an amplification device, such as an additional hub, at a distance of up to 200 meters, and to which an existing commercial connector is applicable.

Communication cables incorporating a plurality of twisted pair components formed around a central member are described. A central member may extend lengthwise along a longitudinal length of a cable, and the central member may include a channel extending lengthwise that defines a longitudinal cavity through the central member. A plurality of unjacketed twisted pair components may be formed around the central member, and each component may include a plurality of twisted pairs of individually insulated electrical conductors Further, a jacket may be formed around the central member and the plurality of twisted pair components.

A cable may include a plurality of twisted pairs of individually insulated conductors and a separator positioned between the twisted pairs. The separator may include a longitudinally extending spine positioned between the plurality of twisted pairs, and a plurality of bristles may radially extend from the spine. A first portion of the bristles may extend between one or more sets of adjacent twisted pairs, and a second portion of the bristles may be compressed towards the spine by one or more of the plurality of twisted pairs. Additionally, a jacket may be formed around the twisted pairs and the separator.

A method for determining a connection order of nodes on a powered audio bus by having the nodes draw power from the powered audio bus, measure the power consumed downstream, determine who is the last node on the bus, and transmit an identifier of the last node to the bus driver.

Disclosed are a wiring harness and a head-mounted device with the same. The wiring harness includes: a signal line including a plurality of signal conductors, a grounding wire including a plurality of grounding conductors, and a power cable including a plurality of power conductors, the signal line, the grounding wire and the power cable being disposed in the same outer sheath, and being sequentially arranged in a first direction.

Cables, including electrical cables. The cables are provided with a series of elements designed to interlock with each other when a first length of cable is pressed against a second length of cable, the element including protrusions and spaces between the protrusions. A user folds a length of cable on itself or on another cable, snugly pressing the protrusions into the spaces, to store the cable, or to restrict the movement of the cable during use. In this manner, movement of the cable is restricted into the configuration set by the user, and preventing the cable from becoming tangled, knotted, or so forth.
