Due to the variety of fiber patch cords and fiber pigtails, the problem of fiber patch cords and fiber pigtails often makes many friends unclear. In fact, the main difference between fiber patch cords and fiber pigtails is that only one end of the pigtail has The connector is connected, and the jumper has a connector at both ends, and the jumper is cut from the middle to be two pigtails. So, what are the specifications and types of fiber patch cords and fiber pigtails, fiber patch cords and fiber pigtails?
What are the specifications and types of fiber patch cords and fiber pigtail fiber patch cords and fiber pigtails?
1. What are fiber jumper and fiber pigtail?
The fiber 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 fiber pigtail has a connector at one end and a fiber connector at the other end. It is connected to the core of other cables in a welded manner and is usually found in the fiber terminal box.
Second, the specifications and types of fiber patch cords and fiber pigtails
Jumpers are generally distinguished by single-mode and multi-mode in data transmission equipment. The color of the single-mode jumper is usually **, and there are two wavelengths, 1310nm and 1550nm respectively, and the transmission distance is 10km and 40km respectively; multimode jumper The color is usually orange, the wavelength is 850 nm, and the transmission distance is 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 the 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 the snap-on connection, the 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.
What are the specifications and types of fiber patch cords and fiber pigtails, fiber patch cords, and fiber pigtails? I believe that friends here have already answered this question. Of course, the use of fiber patch cords and pigtails also has many precautions. For example, the optical modules of the jumper connection must have the same wavelength of transmission and reception, and the pigtails are relatively slender and not resistant to high temperatures. and many more.
