Optical fiber patch cord refers to the patch cord that connects the equipment to the optical fiber wiring link. It has connectors at both ends and has a thicker protective layer. It is generally used for the connection between the optical transceiver and the terminal box.
Fiber Patch Cables (also known as optical fiber connector) means that both ends of the optical cable are equipped with connector plugs. Optical fiber jumpers are divided into single-mode optical fiber jumpers and multi-mode optical fiber jumpers. In optical fiber communication, the commonly used specifications of optical fiber connectors are SC, FC, SC, MTRJ, LC and other models.
Single-mode fiber patch cords generally have a yellow outer skin, and multi-mode fiber patch cords are generally orange. Fiber patch cords are relatively soft and are mainly used for indoor wiring.
Single mode: Only one wavelength can be transmitted, but the wavelength distance is long, generally 1310nm, 1550nm, which is called long wave. Multi-mode: It can transmit multiple wavelengths, but the distance between the wavelengths is not far, generally 850nm, which is called shortwave.
Generally speaking, optical fiber jumpers are used in pairs. In actual wiring, it is not necessary to use them in pairs. The use of optical fiber jumpers in pairs is usually related to the equipment it is connected to. One shot, paired or even used is sometimes based on the requirements of the equipment, such as video optical transceivers. Multi-mode devices need paired fiber jumpers for devices, but single-mode fiber optic transmission does not need to be used in pairs, just one fiber jumper.
Optical fiber jumper is actually a relatively short communication fiber, but because the distance between two optical fiber communication devices is short, it is called optical fiber jumper.
