Hello,
Today, I would like to share with you this topic which Introduce the Fiber Optic Patch Cord.
1- Definition of fiber jumper
Optical fiber jumpers are used to make patch cords from equipment to optical fiber wiring links. There is a thick protective layer, which is generally used in the connection between the optical transceiver and the terminal box.
2- Classification of optical fiber jumpers
According to different transmission media, fiber optic jumpers can be divided into common single-mode and multimode jumpers for silicon-based optical fibers, as well as other optical fiber jumpers that use plastic as the transmission medium; according to the structure of the connector, they can be divided into: FC Jumpers, SC jumpers, ST jumpers, LC jumpers, MTRJ jumpers, MPO jumpers, MU jumpers, SMA jumpers, FDDI jumpers, E2000 jumpers, DIN4 jumpers, D4 jumpers, etc. form.
The more common fiber jumpers can also be divided into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST, etc.
Single-mode fiber (Single-mode Fiber): The general fiber jumper is indicated by, the connector and the protective sleeve are blue; the transmission distance is longer.
Multi-mode fiber (Multi-mode Fiber): Generally, fiber jumpers are shown in orange, and some are shown in gray. The connectors and protective sleeves are beige or black; the transmission distance is short.
3- Precautions for the use of optical fiber jumpers
The transmit and receive wavelengths of the optical modules at both ends of the fiber jumper must be the same, that is to say, the two ends of the fiber jumper must be optical modules of the same wavelength. The simple way to distinguish is that the color of the optical module must be the same. In general, short-wave optical modules use multi-mode optical fibers (orange optical fibers), and long-wave optical modules use single-mode optical fibers to ensure the accuracy of data transmission.
Do not excessively bend or loop the fiber during use, as this will increase the attenuation of light during transmission.
After using the fiber jumper, be sure to protect the fiber connector with a protective sleeve. Dust and oil will damage the coupling of the fiber.
4- The difference between fiber jumpers and pigtails
Optical fiber jumpers are used to make patch cords from equipment to optical fiber wiring links. There is a thick protective layer, which is generally used in the connection of optical fiber jumpers between the optical transceiver and the terminal box.
Pigtails are also called pigtails. Only one end has a connector, and the other end is a broken end of an optical fiber core. It is connected to other optical fiber cores by fusion splicing. It often appears in the optical fiber terminal box and is used to connect the optical cable to the optical fiber transceiver. Devices (couplers, jumpers, etc. are also used in between).
The optical fiber connector is a device that can be detached (movably) connected between the optical fiber and the optical fiber. It is to precisely butt the two end surfaces of the optical fiber, so that the optical energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent and to minimize the impact on the system due to its involvement in the optical link, this is the basic requirement of fiber optic connectors. To a certain extent, fiber optic connectors also affect the reliability and performance of optical transmission systems.
