Detailed explanation of specifications and models of fiber patch cords and fiber pigtails

Optical fiber jumpers are cables that are directly connected to desktop computers or equipment to facilitate the connection and management of equipment. The jumpers have a thicker protective layer and are often used between terminal boxes and optical transceivers. Only one end of the pigtail has a connector, and the other end is an optical fiber connector.

Specifications and Types of Patch Cords and Pigtails

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

FC type jumper: circular optical fiber connector, additional metal sleeve reinforcement, fixed by turnbuckle.

SC-type jumper: rectangular connector, fixed by plug-and-pull type, without rotation.

ST-type jumper: round connector, using snap-on connection, the fixing method is turnbuckle.

LC type jumper: square connector, the fixing method is made of modular jack (RJ) latch principle which is easy to operate.

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

Bundle pigtail: This type of pigtail, also known as pigtail bundle, consists of Corning tight-buffer fiber, aramid fiber reinforcement, and a flame-retardant PVC protective jacket, compared to other types of pigtails. More popular and widely used.

Ribbon pigtail: The ribbon pigtail is the same as the bundle pigtail, both of which are multi-core pigtails. The ribbon pigtail contains 12 core fibers, one end is used for fusion splicing, and the other end is equipped with a connector.

Armored pigtail: The outermost layer of this type of pigtail has an extra layer of metal protective sheath than conventional pigtails, so it will be more durable than ordinary pigtails.

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

Waterproof Pigtail: With a dense protective cover and waterproof sealing connector, it is suitable for harsh environments.
