Patch Cord Optical Fiber jumper LC Dx LSZH Multimode cable
LC Patch cord is a single, short, usually tight-buffered, optical fiber that has an optical connector pre-installed on one end and a length of exposed fiber at the other end.
The end of the pigtail is stripped and fusion spliced to a single fiber of a multi-fiber trunk. Splicing of pigtails to each fiber in the trunk "breaks out" the multi-fiber cable into its component fibers for connection to the end equipment.
Patch cord has 0.9mm 2.0mm and 3.0mm connectors for chosen. Connectors could be mounted in a patch panel, often in pairs, although single-fiber solutions exist, to allow them to be connected to endpoints or other fiber runs with patch fibers. Alternatively, they can have male connectors and plug directly into an optical transceiver.
Features:
Low insertion loss.
High return loss.
Good repeatability;
Good interposition performance;
Good temperature stability;
Strong tensile property.
Optical fiber jumper products are widely used in: communication room, optical fiber to home, local area network, optical fiber sensor, optical fiber communication system, optical fiber connection transmission equipment, national defense combat readiness, etc. It is suitable for cable TV network, telecommunication network, computer optical fiber network and optical test equipment.

In multimode fiber, the diameter of the core is 50 μ m ~ 65 μ m, which is roughly the same as the thickness of human hair. The diameter of single-mode fiber core is 8 μ m ~ 10 μ M. The core is surrounded by a glass envelope with a lower refractive index than the core to keep the fiber in the core. On the outside is a thin plastic jacket to protect the envelope.

According to the joint shape, optical fiber jumper can be divided into FC optical fiber jumper, SC optical fiber jumper, St optical fiber jumper, LC optical fiber jumper, etc;
According to the grinding method (end face) of the insert, it can be divided into: PC (plane), UPC (spherical surface), APC (inclined 8-degree surface), etc. (FC / APC joint is generally required for cable TV optical transceiver);
According to the type of optical fiber, it can be divided into single-mode, 50 / 125 multimode, 62.5/125 multimode, Gigabit, 10 Gigabit, etc;
According to the diameter of tail cable, it can be divided into 900 μ m, 2 mm, 3 mm, etc.
LC-LC multi-mode dual core fiber jumper (also known as optical fiber connector) refers to that both ends of the optical cable are installed with connector plug, and LC-LC multi-mode dual core optical fiber jumper is used to realize the active connection of optical path. Optical fiber patch cord / cable is similar to coaxial cable, while LC-LC multi-mode dual core fiber patch cord has no mesh shield. At the center is the glass core of light transmission. In multimode fiber, the diameter of the core is 50 μ m ~ 65 μ m, which is roughly the same as the thickness of human hair. The diameter of single-mode fiber core is 8 μ m ~ 10 μ M. The core is surrounded by a glass envelope with a lower refractive index than the core to keep the fiber in the core. On the outside is a thin plastic jacket to protect the envelope.
