The different kinds of fiber patch cable


You may listen to the term hybrid or composite cable used.This cable does not constitute a special type of cable but is one that contains multiple smaller cables within a shared cable jacket or spiral wrap.The smaller cables can be the same type or a mixture of cable types.For example,a common cable that is manufactured now contains four-pair type or a mixture of cable types,For example,a common cable that is manufactured now contains four-pair Category 5e UTP cable and two different types of media to single location by pulling only one cable.A number of manufactures, build hybrid cables,however, fiber optic cable corresponds to the unique interface is one of the most frequent is LC, SC, ST these categories, especially LC-LC Single Mode Patch Cord . Then the article will introduce the details for these unusual kinds of fiber patch cable.
Composite cables are also offered by a number of distributors,Keep in mind that bunding Category 5e,6 or 6A UTP cables adversely affects their performance,so make sure that all the cables have been tested for standards compliance after they have been bundled,whether the bunding was done by the manufacturer or the distributor.
Picking the Right Patch Cables.Although not part of a discussion on picking cable types for horizontal cable,the subject of patch cords should be addressed,Patch cables are the cables that are used to connect 110-type connecting blocks,patch panel ports,or telecommunincation outlets to network equipment or telephones.
We've mentioned this before but it deserves repeating you should purchase factory -made patch cables,Patch cable are critical part of the link between a network device and the network equipment ,Determining appropriate transmission requirements and testing methodology for patch cords was one of the holdups in completing the ANSI/TIA/EIA-568B2.1 Category 6 specification,Low -quality,poorly made ,and damaged patch cables very frequently contribute to network problem,Often the patch cable is considered the weakest link in the structured cabling system,Poorly made patch cables will contribute to attenuation loss and increase crosstalk.
In the process of buying should consider the types of fiber optic jumper interface
The characteristics of LC LC Fiber Patch Cord : 8 Angle grinding, low insertion loss and high attenuation, metal parts, standard cubic zirconia ceramic core, fiber diameter, 3.0 mm in general, is used for optical fiber access network, data communication networks, fiber optic measurement instruments, optical fiber data transmission, etc
Factory-made patch cables are constructed using exacting and controlled circumstances to assure reliable and consistent transmission -performance parameters. These patch cables are tested and guaranteed under perform correctly.
Patch cables are made of stranded-conductor cable to give them additional flexibility,However,stranded cable has up to 20 percent higher attenuation values than solid-conductor cable,so lengths should be kept to a minimum,The ANSI/TIA-568-C standard allows for a 5-meter maximum-length patch cable in the wiring closet and a 5-meter maximum length patch cable at the workstation area.
LC LC Fiber Patch Cord
Here are some suggestions to consider when purchasing patch cables:
Do not commit them yourself.Many problems result from faulty patch cables.
Choose the correct category for the performance level you wish to achieve.
Make sure the patch cables you purchase use stranded conductors for increased flexibility.
Purchase is a variety of lengths and make sure you get a few extra of each length.
Consider purchasing patch cords from the same manufacturer that rides the cable and connecting hardware, or manufacturers who has teamed up to provide compatible cable patch cords and connecting hardware.Manufacturers are part of such alliances。
LC-SC Patch Cord
In addition to the above introduction , LC-SC Patch Cord feature low cost, simplicity as excellent durability, ceramic ferrules of SC fiber optic patch cord makes them accurate alignment. These cables are for typical 50/125 and 62.5/125 optional Multimode Fiber. The cable diameter is 2mm or 3mm. SC multimode patch cord is available for PC/UPC/APC version, Dodo.Provide both simplex, duplex cable type and 0.9mm, 2.0mm, 3.0mm cable diameters for choose.
