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.

Some Notes Of Buying Fiber Pigtails

In any fiber optic cable installation, the way the cables are attached to the system–is vital to the success of the telecommunications network. If done well, the connection allows optical signals to pass with low attenuation and little return loss. One of the proven ways to join optical fibers is with a fiber pigtail–a fiber cable with a installed connector on one end and unterminated fiber on the other end.

Pigtails are basically cable assemblies. Ninety-nine percent of singlemode applications use pigtails, also used in many multimode applications. One of the benefits of using pigtail is lower labor costs. The end of the pigtail is stripped back and fusion spliced to another single fiber. This is done easy in field with a multi-fiber trunk to break out the multi-fibers cable into its component for connection to the end equipment. Installers working with singlemode fiber typically have access to a fusion splicer–an expensive piece of equipment that costs $6000 to $30,000 or more. With a fusion splicer you just splice the pigtail right onto the cable in a minute or less.

Pigtails bridge a critical junction in the fiber-optic network. Pigtails consist of–a connector, a ferrule, standard fiber and jacket types, including singlemode and multimode varieties. The most important element you should know is that the quality of the connector itself. You need to know certain characteristics, such as insertion loss, the type of polish used and how well the connector is terminated to the cable. As fiber cable termination is the addition of connectors to each optical fiber in a cable. The fibers need to have connectors fitted before they can attach to other equipment. Two common solutions for fiber cable termination are pigtails and fanout kits or breakout kits.

Ferrule material, whether zirconia ceramic, plastic or stainless steel, must also be specified when buying a pigtail. If you go with a metal ferrule, it is a waste for any singlemode application.

The length of the pigtail is another element that must be specified. The extra slack allows for splicing errors to be corrected, without it, you may have to start with another pigtail.

Pigtails can have female connectors and be mounted in a wall mount or patch panel, often in pairs although single-fiber solutions exist, to allow them to be connected to endpoints or other fiber runs with patch cables. Alternatively they can have male connectors and plug directly into an optical device. Pigtails are different from patch cords, as both ends with connectors, like common patch cord LC-LC.

Testing a pigtail in the field is not easy. The unterminated end is difficult to check until the pigtail is actually spliced to the equipment.
Quality is typically high because the connectorized end is attached in a controlled environment–FiberStore. FiberStore can make singlemode pigtails more accurately than a field termination can be done.
