The similarities and differences between fiber jumpers and fiber pigtails

Fiber patch cords and fiber pigtails, as connecting devices for optical network transmission, have many similarities, which often confuse people. Today we are going to talk about the similarities and differences between fiber jumpers and fiber pigtails for everyone to understand.

The similarities between fiber jumpers and fiber pigtails:

Fiber jumpers and fiber pigtails are divided into single and multimode. The working wavelength of multimode is 850nm, which is mostly used for short-distance transmission; the working wavelength of single-mode is mostly 1310nm and 1550nm, which are mostly used for medium and long-distance transmission; The color of the wire and fiber pigtail is also the same. The color of single-mode fiber and pigtail is yellow, and the color of multi-mode fiber and pigtail is orange; both are simplex and duplex. Simplex has only one connector, duplex There are two connectors; fiber jumpers and fiber pigtails have SC, LC, FC, ST, MPO and other connectors;

The difference between fiber jumper and fiber pigtail:

The fiber jumper is connected to two connectors by a fiber optic cable. The length of the fiber jumper is fixed. The fiber pigtail has a connector at one end, and the other end is a broken fiber core. The fiber pigtail can be spliced ​​and connected. Optical cable. The fiber jumper can be regarded as two fiber pigtails, and one fiber jumper can be cut into two fiber pigtails.

Fiber patch cords are generally used for interconnection between network devices, while fiber pigtails are spliced. They are generally used in protected or need to be spliced ​​connections. They are usually used for fiber distribution frames, splice boxes, and fiber distribution boxes. .

All in all, the biggest difference between fiber pigtail and fiber patch cord is the difference in appearance. The fiber patch cord has connectors on both sides, while the fiber pigtail has only one connector and the other end is bare fiber.
