Twinaxial cabling , or Twinax , is a type of cable similar to coax , but with two inner conductors instead of one. Due to cost efficiency it is becoming common in modern As of? very short range high speed differential signaling applications. Legacy applications IBM Historically, twinax was the cable specified for the IBM 5250 terminals and printers, used with IBM s midrange hosts, iSeries, currently Power systems hardware running IBM s i operating system i5 OS , and also with its predecessors, such as the S 32, S 34, S 36 , S 38 and AS 400 Application System 400 minicomputers. The data transmission is half duplex, balanced transmission, at 1 Mbit s, on a single shielded, 110 twisted pair ref name one cite news url http www.decisiondata.com html tb whattwinax.htm publisher NLynx title NLynx Technologies what is Twinax? date 2006 ref . With Twinax seven devices can be addressed, from workstation address 0 to 6. The devices do not have to be sequential. Straight Twinax cables can go up to convert 5000 ft m . Twinax is a bus topology that requires termination to function properly. Most Twinax T connectors have an automatic termination feature. For use in buildings wired with Category 3 or higher twisted pair there are Balun s that convert twinax to twisted pair and hubs that convert from a bus topology to a star topology. Twinax was designed by IBM as a replacement for RS 232 dumb terminals. Its main advantages were high speed 1 Mbit s versus 9600 bit s and multiple addressable devices per connection. The main disadvantage was the requirement for proprietary Twinax cabling with bulky ... offers 15 to 25 times lower transceiver latency than current 10GBASE T CAT6 CAT6a CAT7 cabling ... T.

Refimprove date April 2012 In the oil and gas industry, the term wireline usually refers to a cabling technology used by operators of Oil well oil and gas wells to lower equipment or measurement devices into the well for the purposes of well intervention and reservoir evaluation. Braided line can contain an inner core of insulated wires which provide power to equipment located at the end of the cable, normally referred to as electric line, and provides a pathway for electrical telemetry for communication between the surface and equipment at the end of the cable. Wireline tools A wireline tool string can be dozens of feet long with multiple separate tools installed to perform multiple operations at once. Natural gamma ray tools are designed to measure naturally occurring gamma radiation in the earth caused by the disintegration due to Potassium, Uranium, and Thorium. Unlike nuclear tools, these natural gamma ray tools do not emit any radiation. Natural gamma ray tools employ a radioactive sensor, which is usually a scintillation crystal that emits a light pulse proportional to the strength of the gamma ray pulse incident on it. This light pulse is then converted to a current pulse by means of a photo multiplier tube PMT. From the photo multiplier tube, the current pulse goes to the tool s electronics for further processing and ultimately to the surface system for recording. The strength of the received gamma rays is dependent on the source emitting gamma rays, the density of the formation, and the distance between the source and the tool detector. The log recorded by this tool is used to identify lithology , estimate shale content, and depth correlation of future logs. Nuclear Tools Nuclear tools measure formation properties through the interaction of reservoir molecules with radiation emitted from the logging tool.

Rollover cable also known as Cisco console cable or a Yost cable is a type of null modem cable that is often used to connect a computer terminal to a router s System console console port. This cable is typically flat and has a light blue color to help distinguish it from other types of network cabling. It gets the name rollover because the pinouts on one end are reversed from the other, as if the wire had been rolled over and you were viewing it from the other side. This cabling system was invented to eliminate sex differences in RS 232 wiring systems. Any two RS 232 systems can be directly connected by a standard rollover cable and a standard connector. For legacy equipment, an adapter is permanently attached to the legacy port. A standard RS 232 rollover cable conforms to the Yost Serial Device Wiring Standard . It s a standard because it has been widely published, both on the Internet, and in the Unix Administrator s Guide.

The term is often used interchangeably to refer to products used for the purpose of managing cables or to the workmanship carried out to cables whilst being installed. Cable management is important in many fields, such as IT, communications, power distribution, facility wiring, local area network s, etc. The purpose of cable management is twofold to support the cables whilst being routed through the building from Point A to B often called containment , and to make subsequent management of the cables through the lifetime of the installation easier. Typically, products such as cable tray s, cable ladders, and cable baskets are used to support a cable through cabling routes. The IT industry has special needs because, unlike heavy power cables, data cables often need to be added, moved, or removed many times during the life of the installation.
