This article summary Fiber optic patchcord (also known as fiber optic connector), that is to say, access to optical fibre connector module, there are a lot of ways, and not interoperability with each other.
LC fiber-optic SFP module connectors, and GBIC are SC fiber optic connectors.
Classification of fiber optic patch cord are summarized as follows: Fiber optic patch cord (also known as fiber optic connector), that is, access to optical fibre connector module, there are a lot of ways, and not interoperability with each other.
LC fiber-optic SFP module connectors, and GBIC are SC fiber optic connectors.
The following is several common network engineering of fiber-optic connectors for detailed description:①-FC optical fiber patch cord: external strengthening is using a metal sleeve, fasten buckle is the form. Generally speaking, ODF (wiring rack up).
② SC-type fiber optic patch cord: connect optical GBIC module connector, its crust is rectangular, fastening method is plug-pin latch, does not need to rotate. (Router switch up).
③ ST fiber optic jumper: commonly used in optical fiber distribution frame, the shell is round, fastening the buckle is. (For 10Base-F connections, connector type usually ST. Often used for optical fiber distribution frame).
④-LC optical fiber patch cord: connect SFP module connectors, it uses easy to use modular jacks (RJ) made from the latch mechanism. (Router).
⑤ MT-RJ fiber optic jumper: square optical connector transceiver, a dual fiber transceiver.
ST, SC connector, connector commonly is used for General network. ST half a week after insertion with a fixed bayonet, the shortcomings are easily broken; SC connector-plug directly is very convenient to use, the problems are easy to fall out; General telecommunications networks use FC Connector, there is a nut onto the adapter, advantages are secure, dust-proof, the disadvantage is just a little too long to install. MTRJ fiber optic jumper consists of two high-precision plastic molding consists of connectors and cables.
Connectors external parts for precision plastic parts, contains push-pull type pluggable clamping mechanism. And is suitable for indoor applications in the telecommunications and data networking systems.
Fiber optic modules: General support hot-pluggable, GBIC fiber interface that is used for SC-or ST; SFP, namely: small package GBIC, is used fiber optic LC type.
Using fiber optics: Single mode: wavelength 1310 l LH wavelength single mode long margin 1310,1550
Model: SM-wavelength 850
SX/LH means that you can use the single-mode or multimode fiber Pigtail connector callout, we often can see "FC/PC", "SC/PC", the meaning is as follows 1 "/" indicates that the pigtail connector earlier models "SC" connector is the standard square connector, plastic, resistant to high temperatures, does not readily advantages.
Transmission device-side optical interface with SC connectors
"LC" connectors with SC connector shape is similar to a small SC connector.
"FC" joint metal connector, generally speaking, ODF, metal connector plug more than plastic.
Connector varieties more signals, in addition to the above three things, also MTRJ, ST, MU, etc,
2.'/' later showed that technology with fiber optic connector section, namely lapping methods
"PC" in the device of the carriers in the most widely used, its connector section is flat.
"UPC" attenuation smaller than "PC" , it is generally used for devices with special needs, some foreign manufacturers to jump within the ODF fiber which is used with FC/UPC, mainly to improve ODF indicator of the device itself.
In addition, in radio, and early application of CATV is mainly "APC" model, with its pigtail head angle in the face, you can improve the quality of your TV signal, due mainly to the TV signal is analog optical modulation, Jointing coupling surface is vertical when light returns along the original path.
Due to non-uniform refractive index profile of optical fiber coupling surface may be returned once again, although energy is small but complete elimination of noise is very difficult to get rid of . due to the analog signal is impossible, it is equivalent to and the original clear signals were superimposed on a weak signal with a delay.
Pigtail headband inclined to return the reflected light it is not along the original path.
General digital signals generally does not have this problem.
