Bundled pigtails, also known as pigtail bundles, multi-core connectors, only have a connector at one end, and a broken end of an optical fiber at the other end, which is connected to other optical fiber cores by fusion splicing, and often appears in the optical fiber terminal box. Used to connect optical cables and terminal equipment.





Pigtails are divided into multi-mode pigtails and single-mode pigtails. The multimode pigtail is orange with a wavelength of 850nm and a transmission distance of 2.5km, which is used for short-distance interconnection. The single-mode pigtail is yellow, with two wavelengths, 1310nm and 1550nm, and transmission distances of 10km and 120km, respectively. It consists of 12 pigtails, the colors of which are: blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, and light blue.





Product Features:


Bundle fiber pigtail is composed of Corning tight-buffered optical fiber that meets full chromatographic specifications, outsourcing aramid fiber reinforced components, and then wrapped with a flame-retardant polyvinyl chloride outer sheath. It is widely used in densely packed transmission lines and terminal equipment. connection.


Uses: CATV, LAN/access network, telecommunications network/Gigabit data network testing, medical equipment, other industrial and military applications




◆ Comply with ANSI, Bellcore, TIA/EIA, IEC and other international standards and domestic telecommunications industry standards


◆ Realize the active connection of optical fiber transmission


◆ Low insertion loss and large return loss


◆ Good interchangeability and repeatability





Optical cable sequence chromatographic arrangement Optical fiber chromatogram 1# -12#: generally blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, cyan.









Bundle-shaped pigtails are generally used in splice trays and integrated trays in optical fiber distribution frames or optical fiber transfer boxes, and can also be used as pigtails in terminal boxes.





The ribbon pigtail and the bundle pigtail are both composed of multi-core. The difference is that the single-core fiber pigtail is prepared for fusion splicing at one end and a connector at one end. Called bundle fiber. The ribbon fiber is a multi-core fiber pigtail containing 12 cores, all of which are fused at one end and a connector at one end.



Both of these two types of optical fibers are rarely used for civilian purposes, and ribbons are basically not used for civilian purposes. Most of them are large-scale communications projects such as telecommunications and mobile. The bundles are also less for civilian use. Most of them are used for industrial projects, and the civilian use is single fiber.



The difference in appearance is the difference between a ribbon and multiple bundles, which can be clearly seen from the name, and the 12 single fibers bundled are different in color. The ribbon is the same.






The ribbon optical cable means that multi-core optical fibers (4, 6, 8, 12 cores, etc.) are glued and arranged with special materials in accordance with relevant standards to form a group (also called a belt), and multiple groups (belts) form an optical cable. Such an optical cable is called a ribbon optical cable. The most commonly used ribbon cables are 6-core and 12-core ribbon cables. Nowadays, there are fewer and fewer ordinary single-core optical cables with a large number of cores, and most of the optical cables with 72 cores or more are ribbon optical cables.







Pigtail is one of the commonly used integrated wiring products in optical fiber integrated wiring system. Used to connect optical cables and optical fiber couplers, optical fiber transceivers, etc. The fiber pigtail can be said to be a dedicated lane between the fiber client system and the main fiber network. According to the optical fiber manufacturer Vicom Communications, usually one end of the pigtail is an optical fiber cable, which is connected to the optical fiber by cold splicing or fusion splicing as a whole, and the other end has an optical fiber head, which connects the optical fiber and the twisted pair by connecting with the optical fiber transceiver. Received the information socket.





The ribbon optical fiber fusion splicer is mainly used for the construction and maintenance of optical cables in optical communications. The main purpose is to melt the two optical fibers by generating an electric arc, and at the same time, use the collimation principle to advance gently to realize the coupling of the optical fiber mode fields. Note: This optical fiber refers to each optical fiber in the optical cable. The fusion splicer is mainly used in the construction, line maintenance, emergency repair, production and testing of optical fiber devices, and research and teaching of scientific research institutes of major operators, engineering companies, enterprises and institutions.





Ribbon fiber


The characteristic of the ribbon fiber is that it is wider than a single fiber. The ordinary single-core communication fiber is a cylindrical shape composed of quartz crystal material with a diameter of 0.125mm, while the 12-core ribbon fiber is flat with a width of 3mm. The overall connection requires 12-core fiber to be connected at the same time, and at the same time heat-shrink protection, the final connection point is the same size as the single-core fiber connection point, giving full play to the characteristics of fast and convenient ribbon fiber connection.
