Armored Cable vs. Flexible Cable: Key Differences

by www.fiber-mart.com When transmitting data or conducting power in harsh environments, protecting your cables is crucial to safe and reliable operation. This is where armored cables come into play. They are used primarily in industrial applications, often in cable trays and raceways. They often not used in flexing applications. While they could operate there, the connector cable would create a weak link. To combat this, you should use either a high-flex cable on the inside or discreet wires. Jacketing materials—such as a silicone tube-covered, thermoplastic elastomer or PVC—further protect the cables from harsh chemicals, oils and sunlight, but also prevent physical failure by repetitive impacts, abrasion with loaded components, and weld slag. In addition, most armored cable jacketing materials are flame resistant. Armored cables  feature some type of metal sheath that is the first layer of armor. It is usually made of interlocking or continuous aluminum or stainless steel, or it

Primary Features of Underground Armored Cable

by www.fiber-mart.com What is the structure of the underground power cable?   Plenty of cables and wires are available for all types of electrical and cable applications. Choosing the correct one can be easy enough if you know, as a professional electrician, what application the product is for. Much of the tine armoured cables are used in mains supplies and underground sewer systems or railways.   There are a variety of armoured cables available including those that are made of 2 to 7 core wires.  Underground armoured cable  has distinct features. They are noted for the different number of conductors within them which are covered with insulation and a layer of protective PVC or other durable material. They also have bedding and a sheath. They are comprised often of Huadong steel wire armoured cable and often called SWA wires.   What are the advantages of underground armoured cable? Electrical power can go through the cables underground, although there are some types th

Use Armored Cables for all your cabling needs

by www.fiber-mart.com Wires enclosed in a metal covering are called  armored cables . Inside the flexible metal covering, are an insulated hot and neutral wires and a bare bonding wire. Armored fiber-optic cables are often placed in a network for an added automated protection. The armoring is of two types: corrugated (Steel Wire Armor) and interlocking (Aluminium Wire Armor). Corrugated armor is a coated steel tape folded around the cable longitudinally found in outdoor cables.   It offers an extra automated and rodent protection. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers virility and a strong crush resistance. A single core armored cable will always have a layer of aluminium wire armor (AWA) instead of steel wire armor (SWA) as the steel in SWA has a much lower conductivity and thus a higher resistance than aluminium.   If it were used in a single core cable, the magnetic field

PLC Splitter Applications in FTTH Network

by www.fiber-mart.com TTH mainly uses PON network technology, which requires a large number of low-cost optical splitters and other optical passive. Optical splitter device is an integral part of FTTH and with the promotion of FTTH, there would be a great market demand. The traditional preparation of optical splitter technology is fiber fused biconical taper (FBT) technology. Its characteristics are mature and simple technology. The disadvantage is that the assigned ones too large, and the device size is too large, which caused the decrease in yield and the rising cost of single channel, shunt reactive stars uniformity will deteriorate. FBT technology based fiber optic splitter preparation techniques have been unable to adapt to the market demand.     PLC splitter  or planar lightwave circuit splitter is a passive component that has the special waveguide made of planar silica, quartz or other materials. It is employed to split a strand of optical signal into two or more strand

Loose-Tube and Tight-Buffer Cable Application of FTTH

by www.fiber-mart.com FTTH makes use of Fiber Optic technology to enhance communication for households. FTTH stands for Fiber to the Home, and many experts believe that  FTTH cable  will soon replace the traditional copper cables. There are various other elements of FTTH. FTTH Flat Drop Cable is generally also known as indoor cable. Other elements of the technology include instrumentation cables and cable glands. Next let us make a brief introduction of cable construction and the difference of Loose-Tube and Tight-Buffer Cable.   Optical-Cable Construction   The core is the highly refractive central region of an optical fiber through which light is transmitted. The standard telecommunications core diameter in use with SMF is between 8  m and 10m, whereas the standard core diameter in use with MMF is between 50m and 62.5m. The diameter of the cladding surrounding each of these cores is125m. Core sizes of 85m and 100 m were used in early applications, but are not typically use

How to Reduce the Cost of FTTH Architecture

by www.fiber-mart.com In our digital world, people increasingly require higher bandwidth to facilitate daily life, whether for leisure, work, education or keeping in contact with friends and family.
