Introduction to Fiber Optic Jumper Structure and Classification

With the rapid growth of traffic data, fiber optic communication, as an emerging technology, has developed rapidly and has a wide range of applications
As one of the main pillars of modern communication, it plays a crucial role in modern telecommunications networks. Understand the structure and classification of fiber optic jumpers
Fiber Optic Patch Cables refer to fiber optic cables with connector plugs installed at both ends, with a thick protective layer, used for connecting cables
The jumper wire from the device to the fiber optic cabling link enables active connection of the optical path. It is mainly used in fiber optic communication systems, fiber optic access networks, and fiber optic cables
Suitable for cable television networks, telecommunications networks, computer fiber optic networks, and optical testing equipment in fields such as data transmission and local area networks.
Fiber optic jumpers have a similar structure to coaxial cables, except that they do not have a mesh shielding layer. The center is a glass core for light propagation, with a diameter of
The difference between multimode fiber and single-mode fiber is that the core is surrounded by a glass envelope with a lower refractive index than the core, and then by a thin plastic outer layer

Cover (made of polyvinyl chloride or Teflon material)

It should be noted that there is a difference between fiber optic jumpers and tail fibers. Only one end of the tail fiber is equipped with a connector plug, and the other end is a fiber optic cable
The broken end of the fiber core, which is connected to other fiber cores through fusion splicing, often appears in the fiber optic terminal box and is used to connect the fiber optic cable with the fiber optic transceiver
Also used are couplers, jumpers, etc. And both ends of the jumper are movable connectors, there are many types of interfaces, and different interfaces require different couplers
The jumper can be split into two and used as a tail fiber.
There are different standards for classifying fiber optic jumpers:
1. According to the connection head, it can be divided into FC, ST, SC, LC, MU, MPO/MTP, E2000, MTRJ, SMA, etc., and the end face contact method
There are PC, UPC, APC, and the connectors used to connect optical modules are mainly LC, SC, MPO/MTP. Fiber optic jumper connectors are used
A necessary consideration for households when choosing fiber optic jumpers.
According to the color of the connector, it can be divided into blue (commonly used for single-mode connectors), beige, and gray (commonly used for multi-mode connectors).
3. According to the color of the tail cover, it can be divided into gray, blue, green, white, red, black, and blue-green.
4. According to the number of fiber cores, it can be divided into single core, dual core, 4-core, 6-core, 8-core, 12 core, 24 core, 48 core, and 72 core or as specified by the customer
5. According to the diameter of the core, it can be divided into multimode fiber and single-mode fiber. 50um-65um is a multimode fiber, which refers to the transmission at a given operating wavelength
Fiber optic cables with multiple modes have high dispersion loss and short transmission distance, making them suitable for short distance fiber optic communication systems. 9um is a single-mode optical fiber
Only one mode of light can be transmitted, with minimal mode to mode dispersion, making it suitable for remote communication.

6. According to ITU-T standards, communication optical fibers are divided into 7 categories: G.651, G.652, G.653, G.654, G.655, G.656, and G.657
Among them, G.651 is a multimode fiber, and G.651-G.657 are single-mode fibers. ISO/EC further divides multimode optical fibers into OM1-0M5, which are five types of multimode fibers
Fiber optic cables are mainly used in local area networks (LANs) and data centers (DCNs), and the fiber optic jumpers mentioned above can be provided.
7. Customized according to customer requirements based on fiber length.
8. According to the material of the outer protective layer of the cable, it can be divided into ordinary type, ordinary flame retardant type, low smoke halogen-free type (LZSH)
Low smoke halogen-free flame retardant type, armor, etc
Armored jumpers, as a new type of fiber optic jumper, can be applied in computer rooms or various harsh environments. Compared to ordinary fiber optic jumpers, armor
The installation of jumper wires increases the protection of stainless steel hoses and has high compressive and tensile properties.
The common types of fiber optic jumpers on the market currently include single-mode OS2 jumpers, multi-mode OM1, OM2, OM3, OM4, and OM5 jumpers.
