The structure of sc fiber optic patch cord apc and sc to lc fiber optic patch cord


Optical fiber jumper is a widely used product now. The main function of sc fiber optic jumper apc and sc to lc fiber optic jumper is to connect the optical fiber directly to the desktop computer or equipment, which is for more convenient connection and management of related equipment. Simple and straightforward would be the patch cords from the equipment to the fiber optic cabling link. There are many characteristics of sc fiber jumper apc and sc to lc fiber jumper, for example, it has a thicker protective layer, which is generally used for the connection between the optical transceiver and the terminal box.

Fiber jumper structure:

Fiber patch cords are similar to coaxial cables, but without the mesh shield. At the center is the glass core where light travels. In a multimode fiber, the diameter of the core is 15 μm to 50 μm, which is roughly the thickness of a human hair. The diameter of the single-mode fiber core is 8μm~10μm.


A glass envelope with a lower index of refraction than the core surrounds the fiber to keep the fiber within the core. On the outside is a thin plastic jacket that protects the envelope.

Optical fiber jumper classification:

Optical fiber jumpers can be divided into common silicon-based optical fiber single-mode and multi-mode jumpers according to different transmission media, and other such as


Optical fiber jumpers with 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, and other forms.


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): Generally, the fiber jumper is shown in yellow, and the connector and protective sleeve are in blue; the transmission distance is longer.


Multi-mode fiber (Multi-mode Fiber): Generally, the fiber patch cord is indicated in orange, and some are indicated in gray, and the connector and protective sleeve are in beige or black; the transmission distance is short.


Note on the use of optical fibers:

The transceiver 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 optical fiber must be optical modules with the same wavelength. In general, short-wave optical modules use multimode fibers (orange fibers), and long-wave optical modules use single-mode fibers (yellow fibers) to ensure the accuracy of data transmission.


Do not bend and loop the optical fiber excessively during use, which will increase the attenuation of light during transmission.


After using the optical fiber jumper, it is necessary to protect the optical fiber connector with a protective sleeve. Dust and oil will damage the coupling of the optical fiber.


If the optical fiber connector is dirty, you can use a cotton swab dipped in alcohol to clean it, otherwise the communication quality will be affected.
