Fiber Optic Access Network Will Be The Main Force Of Internet Information Highway In The Future

As with the rapid development of social information, fiber optic technology and devices which are dedicated to provide transfer of a new business for WAN and fiber optic access network. Developments of MSTP and PON are the most representative. They are also the best solution to provide various new business in the MAN and fiber optic access network which are based on fiber optic transmission technology. As water to the fish, the developments of fiber optic access technology can not without the support and development of fiber optic access devices.

Due to the constantly updated fiber optic access technology and more and more manufacturers’ accession, nowadays the fiber optic access devices categories are more and more obvious, mainly divided into three categories:

  • Fiber optic connection elements, it is applied into telecommunications and computer network terminal connections, related product: Fiber optic patch cable, fiber optic connector and so on.
  • Fiber optic transceiver, it is utilized for computer network data transmission, related products: Fiber optic splitter, fiber patch panels and so on.
  • Fiber optic engineer devices and fiber optic testers, it is specially for large-scale project, related products: Fiber optic fusion splicer, fiber optic testers.

Next we will introduce these three fiber optic access devices with a representative products respectively, they are fiber patch cables, fiber optic splitter, fiber optic fusion splicer.

Fiber optic patch cable (shown as the figure)is fiber optic cable or fiber optical unit which without fiber optic connector, it is used in fiber distribution frames on various link roads. Fiber patch cables are also used in long distance local optical network, data transmission and private network, various testing and control system.

Fiber optic splitter (shown as the figure), someone calls it as fiber coupler, it belongs to optical passive components, it is used in the telecommunications networks, fiber cable television networks, subscriber loop system. Fiber optic splitters can be divided into standard coupler (double branch, unit 1 x 2, that is, the light signal into two power, for example, 1×2 fiber optic splitter, 1 x4 fiber optic splitter, 1 x 8 fiber optic splitter and so on), star/tree fiber splitters and wavelength division multiplexer (WDM, if the wavelength is a high-density separation and wavelength spacing is narrow, it belongs DWDM).

Fiber optic fusion splicer(shown as the figure) is mainly used in telecommunication for fiber optic cables construction and maintenance, it is applied into telecommunication operators, engineering companies, private network, also used in the production of optical passive and active devices and fiber optical modules for fiber splicing.

All above the fiber optic access devices highly improve the data transmission and processing capabilities of fiber optic access network, and at the same time they can bring two advantages:

First, it solved the long distance transmission problems of fiber line attachment,and made its coverage range more widely. In this way, then it can reduce the number of transit nodes through whole the coverage network, make the structure of the network easier.

Second, it satisfied people’s needs to various broadband business, and improve the quality of new business data. It solved the problem of traditional copper cable access network fundamentally and laid a good foundation for achieving the dream of FTTH. I believe that in the future, fiber optic access network will be the main force of internet information highway.

New Application of Fiber Optic Connector Assembly at the Scene

Recent years, PON technology has been more widely used in the fiber optic industry because of its advantages on building cost, protection cost and the broad width. And in China, the three major telecom operators – China telecom, China unicom and China mobile all bring the EPON and GPON into the telecommunication network, at the same time, in order to support the application of PON technology, ODN network is built strongly, then it put forward higher requirements to fiber optic connection, protection as well as the application and management of fiber cable devices, the most obvious device among them is fiber optic patch cable.

We all know that tradition fiber patch cables are made to follow as the certain length of fiber optic connector assembly process, different lengths of fiber cables and connectors composed of a wide variety of fiber patch cords, they can be used in fiber optic patch panels, fiber transfer boxes, fiber cable devices and the connection between the devices and other optical ports, but just because these different fiber patch cables, it bring heavy pressure to storage management. Except this, traditional factory custom the length of fiber patch cables usually more than the actual length if the route and it leaves the length of the excess in a small disk space, we can see from the figure that not only it adds the cost of distribution frame and other cable devices but also not easy to manage, and too longer fiber cables always happens intertwined, knotted squeeze and circumstances, then result in unnecessary trouble, increase the cost of maintenance and management.

longer cable

Therefore, how to control the length of fiber patch cables effectively, to avoid all the trouble. To solve the problem, Fiberstore makes his opinion. we use the on site assembly of fiber connectors, and on the 2 mm or 3 mm fiber pigtail?into end and make fiber patch cable at the scene, replacing the traditional custom factory fiber patch cables, it can greatly alleviate the traditional fiber patch cables left too long, difficulties of managements, frequent failure those a series of maintenance problems. Fiberstore comes with the close communication with all the operators and joint efforts, apply the fiber optic connector assembly of FTTH at the secne into fiber patch cables managements of fiber equipments.

After the constant experiments and used for many time successfully, we have to believe that the embedded optical fiber types of fiber optical connector assembly at the scene will be the first choice for the fiber distribution frame, cable box, optical distribution boxes and other cable device in the future, it also can give ODN network cabling system maintenance and management to bring a revolutionary change.

Faster to Know Fiber Patch Cables and Choose it Correctly

Fiber optic patch cable, a quite simple but necessary fiber optic products in our optical network, all people who works in the fiber optical industry almost have some knowledge about it. It mainly includes a fiber optic cable and a connector on its end parts, and this kind of fiber optic cable is used to communicate with different optical devices or other electronic devices for transmitting the signal, since these points, we can believe that has different types, different connectors, different lengths, different applications and so on. However, these differences can help me choose what we need and today this page will explain fiber patch cables from different aspects and hope this page give you some helps.

fiber patch cable

Firstly, we must have it in mind is fiber optic connector, as you know, at its end parts we can see that many different connectors, the commonly used connectors are ST, SC, LC, MT-RJ, FC, MU, SMA, ESCON, FDDI and etc…, well, the two sides all can be different, it just means such as LC to ST fiber patch cable, FC to sc fiber patch cable and others. Fiber application for fiber optic connectors can be singlemode and multimode patch cable, we usually see it and it sometimes abbreviation as SM and MM patch cable. Of course, they can have different options, for example, singlemode LC to ST fiber patch cable or multimode FC to SC fiber patch cable… The Figure show four common types of fiber connectors.


As for the the differences between singlemode and multimode fiber optic cables, singlemode is an optical fiber cable with a small core (eg 2-9 microns) that supports one mode and multimode is an optical fiber with a core (25-200 microns) that supports several mode and the core size is also different, commonly SM is 8.3/125 and multimode is 62.5/125, except this, singlemode used to high speed, long distance links and multimode used for lower speed and short distance links. Then another category is usually forgotten, the mode conditioning fiber cables, it is specific to gigabit ethernet applications, all these cables are not interchangeable. By the way,there are some types we have to mention it, it is simplex and duplex cable, simplex cable has a single fiber and duplex cable has two fibers and they usually in zipcord (side by side) style, simplex 3mm and duplex 3mm are shown as the Figure.

Secondly, the jacket types are we also nend to know, available jacket types are PVC riser, ofnp plenum, indoor and outdoor riser, indoor and outdoor plenum, aerial and direct burial, waterproof fiber optic patch cords, ribbon fiber optic cables and bunched fiber optic cables. In Fiberstore, PVC/lszh patch cables category are OM1, OM2, OM3 cables and OM4 fiber cables, and the OM3 and OM4 provide data transfer speeds of 10G in 10Gbe high bandwidth applications via OM4 fiber, it is faster than equal μm OM2 fiber, and the OM1 and OM2 fiber cables in Fiberstore all multimode fiber cables.

Finally, the pulling eye option is also important, it is the end of the cable to prevent damage during installation. During the fiber optic installation, the force is redirected to the body of the cable instead of the core or connectors, this reduces the stress and damage to the fibers, it maybe removed and reused. They are used in telecommunication network, active device termination, CATV networks and local area networks.

Well, when we know some knowledge of fiber patch cables, and the next step we need to know where to buy it, there is a quite good site for you, Fiberstore will be you good choice, it has professional solution to provide for you and high quality fiber cables to supply, include fiber optic cables and even fiber optic pigtails, more to say, Fiberstore is doing big sales for the festal arrival, if there are some needs, welcome to have a try.
