Fiber patch cord in Fiber-optic Link

Fiber Jumper Profile:

Fiber patch cord also is called fiber jumper and fiber patch cable .That is the fiber directly connected with the desktop computer or device , to facilitate device connectivity and management.Tt is used as jumper cables from the device to the optical fiber cabling link.

Structure of the fiber pach cord:

Fiber patch cord is similar with coaxial cable,just have not Mesh shield.In the Center of the fiber jumper is the  glass core of light propagation .In multimode fiber,the core ‘s diameter is  15μm ~ 50μm, broadly in line with the thickness of a human hair.Single-mode fiber core diameter is 8μm ~ 10μm. Outside the coresurrounded by a layer of lower refractive index than the core of theglass envelope, so that the fiber remained at the core. And then the outside is a thin plastic coat used to protect the envelope.

Fiber jumper Category

Fiber jumpers according to the different transmission media can be divided into common silicon-based optical fiber single-mode,multimode jumpers, as well as other fiber jumpers such as plastic,such as the transmission medium; connector structure can be divided into: FC jumpers, SC jumper, ST jumpers, LC jumpers, MTRJjumpers, jumper of MPO, MU jumper, the SMA jumper, FDDI, jumper,the E2000 jumper, the DIN4 jumper, the D4 jumper and sovariousform. The more common fiber jumper can also be divided intothe FC-FC, ​​FC-SC, FC-LC, FC-ST, SC-SC, the SC-ST.

Single-mode fiber (Single-mode Fiber): Fiber Jumper with yellowconnector and protective sleeve blue; longer transmission distance.
Multimode fiber (Multi-mode Fiber): The general fiber jumpers with orange and some gray fittings and protection apply beige or black;transmission distance is short.

 The Note for Fiber using:

Fiber jumpers at both ends of the optical module transceiverwavelength must be consistent, that is the two ends of the fiber mustbe the same wavelengths of light module, a simple distinction is thecolor of the optical module to be consistent. Under normal circumstances, the short-wave optical module using multimode fiber (orange fiber), and long wavelength modules use single-mode fiber (yellow fibers), in order to ensure the accuracy of the data transmission.
Fiber do not use excessive bending and circling, this will increasethe attenuation of light during transmission.
Must use the protective cover after the use of fiber optic jumperfiber connector protected from dust and oil will damage the optical fiber coupling.
If fiber optic connectors are dirty, then you can use a cotton swab dipped in alcohol to clean, otherwise it will affect the communication quality.

Characteristics of fiber jumpers:

(1) low insertion loss
(2) and good repeatability
(3) Return Loss
(4)Mutual insert performance
(5) good temperature stability

Application of fiber optic jumper:

Fiber Jumpers products are widely applied to: the communications room, fiber to the home, local area networks, fiber optic sensors, optical fiber communication systems, fiber optic connectorstransmission equipment, and defense readiness. Applicable tocable television and telecommunications networks, computer andfiber-optic network, and optical test equipment. Subdivision down is mainly used in several ways.
An optical fiber communication system
(2) optical access network
3 fiber-optic data transmission
(4) fiber optic CATV
(5) a local area network (LAN)
6. Test equipment
7 fiber optic sensors
