What is fiber optics?

We're used to the idea of information traveling in different ways. When we speak into a landline telephone, a wire cable carries the sounds from our voice into a socket in the wall, where another cable takes it to the local telephone exchange. Cellphones work a different way: they send and receive information using invisible radio waves—a technology called wireless because it uses no cables. Fiber optics works a third way. It sends information coded in a beam of light down a glass or plastic pipe. It was originally developed for endoscopes in the 1950s to help doctors see inside the human body without having to cut it open first. In the 1960s, engineers found a way of using the same technology to transmit telephone calls at the speed of light (normally that's 186,000 miles or 300,000 km per second in a vacuum, but slows to about two thirds this speed in a fiber-optic cable).

What types of material to choose for the tension of fiber cables?

There are some types of material which is for the function of enhancing the tension for fiber cables:1. Metallic elements: Steel wire, either can be phosphatized steel wire,which is with better price and same ability for enhancing the cable's tensile strength;  or ganvalized steel wire, which is with excellent anti-corrosion property.2. Non-metallic emements, which is also called dielectirc parts.:A. Aramid yarn: using inside the jacket usually, brings the excellent tensile strength in light weight; it is most popular to be used for indoor cable and ADSS cable. B.

How many types of fiber optical cables we produce?

An optical fiber cable is a type of cable that has a number of optical fibers bundled together, which are normally covered in their individual protective plastic covers. Optical cables are used to transfer digital data signals in the form of light up to distances of hundreds of miles with higher throughput rates than those achievable via electrical communication cables. All optical fibers use a core of hair-like transparent silicon covered with less refractive indexed cladding to avoid light leakage to the surroundings. Due to the extreme sensitivity of the optical fiber, it is normally covered with a high-strength, lightweight protective material like Kevlar. Optical fiber cable is widely used in fiber optic communications.And Rux Fiber can produce these types cable is below:Simplex Fiber Optical CableDuplex Fiber Optical CableDistribution Fiber Optical CableBreakout Fiber Optic CableLoose Tube Fiber Optic CableRibbon Fiber optical Cable

What is single mode fiber and multi mode fiber

Fiber optic cable functions as a "light guide," guiding the light introduced at one end of the cable through to the other end. The light source can either be a light-emitting diode (LED)) or a laser.The light source is pulsed on and off, and a light-sensitive receiver on the other end of the cable converts the pulses back into the digital ones and zeros of the original signal.Even laser light shining through a fiber optic cable is subject to loss of strength, primarily through dispersion and scattering of the light, within the cable itself. The faster the laser fluctuates, the greater the risk of dispersion. Light strengtheners, called repeaters, may be necessary to refresh the signal in certain applications.While fiber optic cable itself has become cheaper over time - a equivalent length of copper cable cost less per foot but not in capacity. Fiber optic cable connectors and the equipment needed to install them are still more expensive than their copper counterparts.Single Mode cable is a single stand (most applications use 2 fibers) of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission.  Single Mode Fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310 or 1550nm. Carries higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width. Synonyms mono-mode optical fiber, single-mode fiber, single-mode optical waveguide, uni-mode fiber.Single Modem fiber is used in many applications where data is sent at multi-frequency (WDM Wave-Division-Multiplexing) so only one cable is needed - (single-mode on one single fiber)Single-mode fiber gives you a higher transmission rate and up to 50 times more distance than multimode, but it also costs more. Single-mode fiber has a much smaller core than multimode. The small core and single light-wave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.   Single-mode optical fiber is an optical fiber in which only the lowest order bound mode can propagate at the wavelength of interest typically 1300 to 1320nm.Multi-Mode cable has a little bit bigger diameter, with a common diameters in the 50-to-100 micron range for the light carry component (in the US the most common size is 62.5um). Most applications in which Multi-mode fiber is used, 2 fibers are used (WDM is not normally used on multi-mode fiber).  POF is a newer plastic-based cable which promises performance similar to glass cable on very short runs, but at a lower cost.Multimode fiber gives you high bandwidth at high speeds (10 to 100MBS - Gigabit to 275m to 2km) over medium distances. Light waves are dispersed into numerous paths, or modes, as they travel through the cable's core typically 850 or 1300nm. Typical multimode fiber core diameters are 50, 62.5, and 100 micrometers. However, in long cable runs (greater than 3000 feet [914.4 meters), multiple paths of light can cause signal distortion at the receiving end, resulting in an unclear and incomplete data transmission so designers now call for single mode fiber in new applications using Gigabit and beyond.

What is The Common Structure of Fiber Optic Cable?

For indoor applications, the jacketed fiberis generally enclosed, with a bundle of flexible fibrous polymer strengthmembers like Kevlar aramid, in a lightweight plastic cover to form a simplecable. Each end of the cable may be terminated with a specialized optical fiberconnector to allow it to be easily connected and disconnected from transmittingand receiving equipment. For use in more strenuous environments, amuch more robust cable construction is required. In loose-tube construction thefiber is laid helically into semi-rigid tubes, allowing the cable to stretchwithout stretching the fiber itself. This protects the fiber from tensionduring laying and due to temperature changes. Loose-tube fiber may be gel-filled.a loose tube, the fiber may be embedded in a heavy polymer jacket, commonlycalled "tight buffer" construction. Tight buffer cables are offeredfor a variety of applications, but the two most common are "Breakout"and "Distribution". Breakout cables normally contain a ripcord, twonon-conductive dielectric strengthening members (normally a glass rod epoxy),an aramid yarn, and 3 mm buffer tubing with an additional layer of Kevlarsurrounding each fiber. The ripcord is a parallel cord of strong yarn that issituated under the jacket of the cable for jacket removal. Distribution cableshave an overall Kevlar wrapping, a ripcord, and a 900 micrometer buffer coatingsurrounding each fiber. These fiber units are commonly bundled with additionalsteel strength members, again with a helical twist to allow for stretching. A critical concern in outdoor cabling is toprotect the fiber from contamination by water. This is accomplished by use ofsolid barriers such as copper tubes, and water-repellent jelly orwater-absorbing powder surrounding the fiber. Finally, the cable may be armored toprotect it from environmental hazards, such as construction work or gnawinganimals. Undersea cables are more heavily armored in their near-shore portionsto protect them from boat anchors, fishing gear, and even sharks, which may beattracted to the electrical power that is carried to power amplifiers orrepeaters in the cable. Modern cables come in a wide variety ofsheathings and armor, designed for applications such as direct burial intrenches, dual use as power lines, installation in conduit, lashing to aerialtelephone poles, submarine installation, and insertion in paved streets.

What is Fiber Optic?

Optical fiber consists of a core and acladding layer, selected for total internal reflection due to the difference inthe refractive index between the two. In practical fibers, the cladding isusually coated with a layer of acrylate polymer or polyimide. This coatingprotects the fiber from damage but does not contribute to its optical waveguideproperties. Individual coated fibers (or fibers formed into ribbons or bundles)then have a tough resin buffer layer or core tube(s) extruded around them toform the cable core. Several layers of protective sheathing, depending on theapplication, are added to form the cable. Rigid fiber assemblies sometimes putlight-absorbing ("dark") glass between the fibers, to prevent lightthat leaks out of one fiber from entering another. This reduces cross-talkbetween the fibers, or reduces flare in fiber bundle imaging applications.
