The difference between fiber and pigtail, the difference between pigtail and network cable

Pigtail is just another form of optical fiber, generally used in the end of optical communication, connected with optical equipment, so called pigtail, optical fiber is the backbone of optical communication used in the optical guide line, generally multiple packages, sandwiched in the middle of a steel wire to improve strength or fixed.

To understand it simply, you can understand the difference between a network cable and a jumper.

The pigtail is used to connect your optical fiber to the adapter of the device, and the optical fiber is the transmission carrier of data, which can also be considered as a connector.

A fiber hose is used to connect optical fibers and fiber couplers.

A half-jumper-like connector that includes a patch cord connector and a length of fiber. Or connect the transmission device and the ODF rack. Wait.

The pigtail is generally used to connect the terminal equipment (which can be understood as the splice wire), and is mainly used to connect with the main optical brazing wire. Mainly to save time, when we first opened the brazing, the master made the pigtail himself very slowly. It's easy to do with pigtails, as long as you can accommodate it.

Fiber optic patch cords have connectors at both ends, and pigtails have connectors at only one end.

Fiber optic patch cord refers to the optical fiber that is directly connected to the desktop computer or equipment to facilitate the connection and management of the device. It is used as a patch cord from the device to the fiber optic cabling link. It has a thick protective layer, which is generally used for the connection between the optical transceiver and the terminal box.

Pigtail, also known as pig tail wire, only one end has a connector, and the other end is a broken end of an optical cable core, which is connected to other optical cable cores through welding, and often appears in the optical fiber terminal box, which is used to connect the optical cable and the optical fiber transceiver (couplers, jumpers, etc. are also used between them). Optical fiber connector is a detachable (moving) connection between optical fibers and optical fibers, which is the two end faces of optical fibers precisely docked, so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the greatest extent, and the impact on the system is minimized due to its involvement in the optical link, which is the basic requirement of optical fiber connectors. To a certain extent, optical fiber connectors also affect the reliability and performance of optical transmission systems.

Same as optical patch cords, when the connecting cable is an optical cable (mostly indoor optical cable) passes the standard test line test, it is called optical cable pigtail, and when the connecting line is an optical fiber (usually a tightly sheathed optical fiber), it is called an optical fiber pigtail. There is no special product standard for optical pigtail, and most buyers and sellers change to "arbitrary" when they deliver the product in the form of optical jumpers, and the quality acceptance is the same as that of optical jumpers, and it is also the standard of optical fiber movable connectors.

Pigtail is an important component of the optical communication system, which is mainly used to realize the interconnection of optical ports between devices and the interconnection between devices and optical cable cores. Different from conventional cables, pigtail core wires have the characteristics of easy breakage and weak tensile resistance, and there is no mature on-site processing scheme for interface parts, so it is impossible to make pigtails with appropriate length according to the actual distance on site.

Therefore, in practical application, pigtails are usually processed and manufactured in factories according to a certain nominal length series, and when installing and constructing on site, engineers can choose pigtails that are larger than the actual distance length. Because pigtails have the characteristics of discrete length and easy damage, pigtails coiling is the core link of pigtail installation, return and storage.

The inner core of the pigtail is carried by silica glass filament, which is fragile and easy to break, and the backbone line is usually a 48-core ADSS optical cable, which needs to be inserted into the bellows and laid into the floor compartment or cable interlayer. There is no effective tool to assist in the traditional pigtail threading method, and the operation and maintenance personnel use the traditional brute force method to pass the pigtail through the bellows, resulting in more fiber jumper damage and a high probability of business interruption.

1.Different uses: pigtails are fiber optic cables used to connect network equipment such as servers and switches, while network cables are twisted pair cables used to connect computers or other network devices.

2.Different transmission speeds: pigtails are a type of fiber optic cable that can support higher data transfer rates, up to hundreds of Gbps or even Tbps levels; A network cable, on the other hand, is a twisted-pair cable that typically transmits at a rate of hundreds of Mbps or in a different way of transmitting signals

The pigtail adopts optical signal transmission, which can avoid problems such as electromagnetic interference and signal attenuation, and the stability and reliability of signal transmission are higher; The network cable uses electrical signal transmission, and the stability and reliability of its signal transmission are affected by electromagnetic interference and signal attenuation, and the quality of signal transmission needs to be improved by taking measures such as shielding and enhancement.

Different transmission speeds: A pigtail is a fiber optic cable that can support higher data transfer rates, up to hundreds of Gbps and very permeable circles to Tbps levels; The network cable is a kind of twisted pair cable, and its transmission rate is usually hundreds of Mbps or The signal transmission mode is different: the pigtail adopts optical signal transmission, which can avoid problems such as electromagnetic interference and signal attenuation, and the stability and reliability of signal transmission are higher; The network cable uses electrical signal transmission, and the stability and reliability of its signal transmission are affected by electromagnetic interference and signal attenuation, and the quality of signal transmission needs to be improved by taking measures such as shielding and enhancement.

Excuse me, but please go into more detail?

4.Different: Pigtails are relatively expensive to manufacture and install, and relatively expensive; Ethernet cables, on the other hand, are relatively cheap.

Therefore, when selecting pigtails and network cables, it is necessary to select suitable cables according to the actual network environment and requirements. If Changshi potato needs to support higher speed data transmission and more stable signal transmission, pigtail can be selected; If you're just connecting between computers or other network devices, you can choose a netback cable.

In general, the short-wave optical module is equipped with a multi-mode jumper, and the long-wave optical module is paired with a single-mode jumper to ensure the accuracy of data transmission. Jumpers should reduce the looping as much as possible during the wiring process, which can reduce the attenuation of the optical signal during the transmission process. The connector of the jumper should be kept clean, and the connector should be encapsulated with a protective sleeve after use to prevent oil and dust from entering, and if there is stain, a cotton swab dipped in alcohol should be used to clean it.

The pigtail is relatively slender, the cross-section of the pigtail is at an angle of 8 degrees, it is not resistant to high temperatures, and it will be damaged if it exceeds 100, so it should be avoided to be used in a high-temperature environment. Optical fiber connector is an important part of optical fiber communication, in terms of data transmission, the quality of the ferrule, the technology and method of production all determine the stability of data transmission.

One connector for pigtails and two connectors for fiber optic patch cords.

Pigtail MMPO-16F-OM5 fiber optic patch cord.

One end of the pigtail without a connector is spliced with the fiber optic cable, and the other end has a connector connected with the fiber patch cord.

Pigtail, also known as pig pigtail, is the optical fiber used to connect the optical cable terminal box to the device.

Pigtails are often classified as single-mode or multi-mode, single-fiber or dual-fiber, transmission distance, and pigtail interface types. At present, there are four types of pigtail interfaces commonly used in optical fiber equipment on the market: FC, SC, LC, and ST.

Type 1: FC interface type.

FC connectors, also known as round threaded fittings (most used on patch panels), are metal connectors, which are generally used on the ODF side, and metal connectors can be plugged and unplugged more times than plastics.

Type 2: SC interface type.

SC connectors, also known as snap-on square connectors (the most used on router switches), are standard square connectors, made of engineering plastics, which have the advantages of high temperature resistance and not easy to oxidize. The optical interface on the side of the transmission equipment generally uses SC connectors.

The third type: LC interface type.

The LC connector is similar in shape to the SC connector and is smaller than the SC connector.

Fourth: ST joints.

ST connectors are also known as snap-on round connectors, and for 10BASE-F connections, connectors are usually ST type.

Generally, there is a SC FC ST LC connector, and the fiber optic pigtail is also called pig tail

There are many interface types of fiber optic pigtails, and their names, descriptions, and shapes are shown in the following figure

The method of making optical fiber connectors is as follows:

1. Prepare tools, in order: Miller pliers, strippers, cold splices, cut-to-length strippers, cutting knives;

2. Peel off the smooth leather line;

3. Peeled off the smooth skin line;

4. Put the smooth leather wire into the fixed-length stripper (generally called caliper in our place), and buckle the upper cover according to the length reserved as needed;

5. Prepare to peel off the optical fiber coating with Miller pliers;

6. After peeling off the coating, cut the fiber.

**The middle is a cold connector, just plug it in.
