Why coaxial cable

Harbor Energy Solutions primary focus is high performance, high efficiency, and cost reduction. Our recommended manufacturers provide unsurpassed cutting edge technology and reliability. These qualities coupled with our industry knowledge, analysis and customized solutions are how we exceed our customers expectations. Cable Bus is a power distribution system using multiple parallel conductors secured in a rigid enclosure.

Superior Bus is a custom-engineered cable bus power distribution system, but with increased performance characteristics. Each conductor fully insulated and continuous from source to load in superior casing.

What is coaxial cable? Center conductor - copper-clad steel. Center conductor bond - clean stripping polymer is utilized to block moisture migration. Dielectric - polyethylene providing mechanically stable, closed cell foam with high VP. First outer conductor - shield with an aluminum-polymeraluminum tape securely bonded to the dielectric core.

Second outer conductor - an additional aluminum-polymer-aluminum tape is used in tri-shield and quad-shield constructions to further enhance HF shield isolation before and after flexure. Third outer conductor - an additional aluminum-polymer-aluminum tape is used in tri-shield and quad-shield constructions to further enhance HF shield isolation before and after flexure. Fourth outer conductor - an additional 34 or 36 AWG aluminum braid is used in quad-shield constructions to further improve LF shield isolation in extreme RF noise environments.

Corrosion resistant protectant Indoor and aerial - a non-drip material designed to eliminate moisture migration into the cable construction. Underground - a flowing compound able to seal small jacket ruptures. Jacket - a UV stable outer jacket of either polyethylene PE or flame retardant polyvinyl chloride PVC is available to protect the core during installation and for the installed life of the cable. Integral messenger - a galvanized, carbon steel wire support member attached to the cable by a separable web.

Which is better: coaxial cable or fiber optic cable? Broadband coaxIal cable supports the frequency range above 4kHz and are used for analog signals. So it must be used with a modem. The digital signal inserted on these cables is encoded using Manchester or Differentia,l Manchester coding. The digital signal consumes the entire frequency spectrum of the cable. So it is not possible to transmit multiple channel using FDM. The transmission of digital signal on the cable is bi-directional.

For 1Km cables the bandwidth is Gbps. Longer cables can be used with low data rates or periodic amplifiers. Broadband coaxial cables are 75 ohm cables used for analog transmission. The baseband co-axial cable was originally used for the Ethernet system that operates at 10 Mbps. They use standard cable television technology. To transmit digital signals on an analog network, each interface must have converters i. The maximum length of baseband co-axial cable between two repeaters is dependent on the data rates.

Since broadband is used for large area, it requires amplifiers which are unidirectional. In dual band systems two identical cables run together, one used for outgoing data, one for incoming data. Different bandwidths are given for inbound and outbound cables. Features: It provides better immunity than twisted pair. This cable is able to transmit data at higher rates.

Limitations: High installation cost. The center of a coaxial cable has a thin wire conductor. Surrounding the copper wire is a layer of plastic for insulation. Op top is a wire mesh layer for more insulation and the last later is another rubber later. Each end of the cable has a thin layer of copper that can be screwed into the receiving electronics i.

In addition to the common shielding and jacketing in most designs, industrial coaxial cables often feature jackets that are UV, chemical, halogen and flame resistant.
