The type of fiber optic patch cable interface and scope of application

Fiber optic patch cable categorized and summarized as follows:
Fiber patch cable is access to the optical module fiber optic connection, have a good variety, and may not be interoperable. SFP module with LC fiber optic patch cable, the GBIC module connected SC fiber optic patch cable. The following detailed description of several commonly used in network engineering fiber optic connection:
① FC fiber optic patch cable: External strengthen the use of metal fastening method for the turnbuckle. Generally used in the ODF side up (Patch panel)
② The SC fiber optic patch cable: connector to connect the GBIC optical modules, and its shell is rectangular fastening method is the use of plug pin latch type, do not need to rotate. (Routers, switches, the most widely used)
③ ST fiber optic patch cable: commonly used in fiber optic patch panel, shell round in shape, fastening methods for the turnbuckle. (For 10Base-F connections, the connectors are usually ST type commonly used in fiber optic patch panel)
④ The LC fiber optic patch cable: connected to the SFP module connector, it uses that the easy to operate modular jack (RJ) latch mechanism is made. (Commonly used in routers)
⑤ MT-RJ fiber optic patch cable: send and receive one of the square fiber optic connectors, one dual fiber transceiver
ST, SC connectors connector commonly used in general network. ST inserted after rotating a half weeks of a fixed bayonet, the drawback is easily broken; SC connector plug directly, very easy to use, the drawback is easy to fall out; FC connectors general telecommunications network using a nut screwed onto the adapter. The advantage is solid, anti-dust, the drawback is that the installation a little longer. MTRJ type fiber optic jumper by two high-precision plastic molded connectors and fiber optic cable. Outside of the connector is a precision plastic parts, including the tight organization of the push-pull plug card. For indoor applications in the telecommunications and data network systems.
Fiber modules: general are hot-swappable-GBIC fiber-optic interface and more to SC or ST type; SFP: small packa GE GBIC, fiber optic LC type.
Use of fiber:
Single-mode: L 1310 Single-mode long distance LH wavelengths 1310, 1550
Multimode: SM wavelength 850
SX / LH can use single-mode or multimode fiber
Said pigtail connector marked, we can often see FC / PC,SC / PC etc., its meaning is as follows
in front of part of said pigtail connector models
connector is the standard rectangular connector, engineering plastics, high temperature, not easily oxidized advantages. Transmission equipment sidelight interface generally with SC connector
LC connectors with SC connectors are similar in shape, smaller than the SC connector.
FC connector is a metal connector, usually used in the ODF side, pluggable metal joints more often than plastic.
More varieties signal connector, in addition to the three described above, as well as MTRJ, ST, MU,
behind the cross-section technology that fiber optic connectors, ie, polishing
PC in the equipment of telecom operators is the most widely used, the joint cross-section is flat.
UPC attenuation is smaller than the PC generally used for devices with special needs, some foreign manufacturers ODF frame internal jump fiber with the FC / UPC, mainly to improve the indicators of the ODF device itself.
In addition, it is used more often in the CATV broadcasting and early model of APC Pigtail head with the inclination of the face, can improve the quality of television signals, mainly due to the TV signal is analog optical modulation, when the connector coupling The surface is perpendicular to the reflected light returns along the original path.
The fiber refractive index profile of uneven will again return to the coupling surface, although the energy is very small but because of the analog signal can not completely eliminate the noise, so the equivalent of a clear signal superimposed on a weak signal with a delay performance is ghosting on the screen. Pigtailed headband angle allows the reflected light returns along the original path. General digital signal there is generally no problem.
Use:
A: optical fiber communication systems
B: fiber-optic broadband access network
C: fiber optic CATV
D: local area network LAN
E: fiber-optic instrument table
F: fiber optic sensors
G: fiber-optic data transmission system
H: Test Equipment
