The difference between fiber jumper and fiber pigtail is different

[Guide] The types of jumpers and pigtails are very rich. The main difference between jumpers and pigtails is that only one end of the pigtail has a connector, and the jumper has connectors at both ends. Generally speaking, the jumper is cut from the middle. It’s two pigtails.

The types of jumpers and pigtails are very rich. The main difference between jumpers and pigtails is that the pigtails have connectors at one end, and the jumpers have connectors at both ends. Generally speaking, the jumpers are cut from the middle and are two tails. Fiber.

1. What are the jumpers and pigtails?

A jumper is a cable that is directly connected to a desktop computer or device to facilitate connection and management of the device. The jumper has a thick protective layer and is often used between the terminal box and the optical transceiver.

The pigtail has a connector at one end and a fiber connector at the other end. It is connected to the core of other fiber optic cables in a welded form, and is usually found in the fiber terminal box.

Second, the specifications and types of jumpers and pigtails

Jumpers are generally distinguished by single mode and multimode in data transmission equipment. The color of single mode jumper is usually yellow, and there are two wavelengths, 1310nm and 1550nm respectively, and the transmission distance is 10km and 40km respectively; multimode jumper color It is usually orange with a wavelength of 850 nm and a transmission distance of 500 m. According to the type of connector, it can be divided into the following types:

FC type jumper: round fiber optic connector, reinforced with additional metal sleeve, fixed in the form of a turnbuckle.

SC type jumper: rectangular connector, fixed in the way of plugging and unloading, no need to rotate.

ST type jumper: round connector, with snap-on connection, fixed way is screw buckle.

LC type jumper: square connector, fixed in a convenient modular jack (RJ) latching principle.

The types of pigtails are mainly single-core pigtail, double-core pigtail, 4-core pigtail, 12-core bundle pigtail, 12-color bundle pigtail, SC bundle pigtail, FC bundle pigtail, LC bundle Pigtail and ST bundle pigtails. In addition to these, it can be divided into the following types:

Bundle pigtail: This pigtail is also known as the pigtail bundle. It consists of Corning tight-fitting fiber, aramid fiber reinforced components and flame-retardant PVC protective sleeve, compared to other types of pigtails. More popular and widely used.

Ribbon pigtail: The ribbon pigtail is the same as the bundle pigtail. Both are multi-core pigtails. The ribbon pigtail contains 12-core fiber, one end is used for welding, and one end is equipped with a connector.

Armored pigtail: The outermost layer of this pigtail adds a metal protective cover to the conventional pigtail, so it is more durable than ordinary pigtails.

Fiber pigtail: low insertion loss, high return loss, good interchangeability and repeated insertion and insertion, very convenient to use.

Waterproof pigtail: with a dense protective sleeve and waterproof sealing joint for use in harsh environments.

Third, the application of jumpers and pigtails

The jumper is mainly used for the connection between the optical fiber distribution frame or the optical information socket to the switch, the connection between the switch and the switch, the connection between the switch and the desktop computer, and the connection between the optical information socket and the desktop computer, and the application is applicable. For management, equipment, and workspace subsystems.

Pigtails are mainly used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission, fiber optic CATV, local area network (LAN), test equipment, fiber optic sensors, serial servers, FTTH/FTTX, telecommunications networks, and pre-terminated installations.

Fourth, the jumper and pigtails precautions

1. The wavelength of the optical module connected to the jumper must be the same. In general, the short-wavelength optical module is matched with the multi-mode jumper, and the long-wavelength optical module is matched with the single-mode jumper to ensure the accuracy of data transmission.

2. The jumper reduces the winding as much as possible during the wiring process, which can reduce the attenuation of the optical signal during transmission.

3. The connector of the jumper should be kept clean. After use, apply the protective cover to enclose the joint to prevent oil and dust from entering. If stains are applied, use a cotton swab to pick up the alcohol.

4, the pigtail is relatively slender, the cross section of the pigtail is 8 degrees, not high temperature, it will be damaged when it exceeds 100 °C, so avoid using it in high temperature environment.

V. Conclusion

In fiber-optic transmission systems, pigtails and jumpers are the main tools. Nothing is missing. There are also very high requirements for data transmission. The quality of the ferrules and the techniques and methods of fabrication determine the stability of data transmission.

The bundle pigtail, also known as the tail fiber bundle, has a connector at one end and a broken end of the fiber at the other end. It is connected to the core of other fiber optic cables by fusion, and is often found in the fiber terminal box for connecting the fiber optic cable. Terminal Equipment. The pigtails are divided into multi-mode pigtails and single-mode pigtails. The multimode pigtail is orange with a wavelength of 850 nm and a transmission distance of 500 m for short-distance interconnection. The single-mode pigtail is yellow with two wavelengths, 1310nm and 1550nm, and the transmission distance is 10km and 40km respectively. It consists of 12 pigtails in the following order: blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, light blue.
