Type and application range of fiber optic jumper interface

The

Fiber jumper (also known as the optical fiber connector), which is the optical connector to access the optical module, also has many kinds, and can not be mutually used. The SFP module is connected to the LC fibre optic connector, while the GBIC is connected to the SC fiber optic connector. The following is a detailed description of several commonly used optical fiber connectors in Network engineering:

①FC Type fiber jumper: The external strengthening method is a metal sleeve, and the fastening mode is turnbuckle. Generally used on ODF side (most of the wiring rack)

②sc fiber jumper: Connectors connecting the Gbic optical module, its shell is rectangular, the fastening mode is a plug-pull latch, no need to rotate. (The router switch is the most used)

③st Type optical fiber jumper: Commonly used in fiber distribution frame, the shell is round, fastening mode is turnbuckle. (For 10BASE-F connections, connectors are usually St types.) Commonly used in fiber-optic wiring Racks

④LC fiber jumper: A connector that connects the SFP module, which is made of a convenient modular jack (RJ) latch mechanism. (Common routers)

⑤mt-rj Optical fiber jumper: Send and receive one square fiber connector, one double fiber transceiver

ST, SC Connector connectors are commonly used in general networks. St head inserted after the rotation half a week has a card mouth fixed, the disadvantage is easy to break; SC connector plug directly, the use is very convenient, the disadvantage is easy to fall out; FC Connection head General Telecommunication network adopts, have a nut to twist to the adapter, the advantage is reliable, dust-proof, the disadvantage is a slightly longer installation time. The MTRJ fiber jumper is made up of two high-precision plastic-shaped connectors and optical cables. Connector external parts for precision plastic parts, including push-pull Plug and pull card clamping mechanism. It is suitable for indoor application in telecommunication and data network system.

Fiber-optic modules: Generally support hot-swappable, gbic use of fiber interface mostly SC or ST; SFP, which is a small encapsulated gbic, using a LC-type optical fiber. Fiber used by

:

Single mode: l Wavelength 1310 single-mode long distance lh wavelength 1310,1550

multimode: SM Wavelength 850

SX/LH indicates the use of Single-mode or multimode fiber

In the label of the tail fiber connector Note, we often see "fc/pc", "SC/PC" and so on, the meaning of the following

1 "/" The previous section of the connector model for the tail fiber

"SC" connectors are standard square joints, the use of engineering plastics, with high temperature, not easy oxidation advantages. Transmission Equipment side Light Interface General with SC Connector The

LC connector is similar to the SC connector shape, smaller than the SC connector. The

FC Connector is a metal connector that is generally used on ODF side,The metal joint can be inserted more than the number of plastic. The

Connector has a variety of signals, in addition to the above three species, there are mtrj, ST, mu, etc.,

2. ' /' Back shows the fiber-optic connector section process, that is, the grinding method

"PC" is the most widely used in telecommunication operator's equipment, its joint section is flat.

"UPC" is less than the "PC", generally used for equipment with special needs, some foreign manufacturers ODF frame internal jump fiber is FC/UPC, mainly for the improvement of ODF equipment own indicators.

In addition, the "APC" model is used in radio and television and early CATV, the tail fiber head adopts the end face with dip angle, which can improve the quality of TV signal, mainly because the TV signal is analog light modulation, when the coupling surface of the joint is perpendicular, the reflected light is returned along the original path. Because the optical fiber refractive index distribution of uneven will return to the coupling surface, although the energy is very small but because the analog signal is unable to completely eliminate noise, so the equivalent in the original clear signal superimposed on a weak signal with delay, performance in the picture is ghosting. The angle of the head band of the pigtail can make the reflected light not return along the original path. General digital signals do not generally have this problem.
