Fiber Optic Patch Cables consists of one or more glass or plastic fiber cores encased in a glass tube,called cladding.The fiber cores and cladding are surrounded by a PVC cover. Signal transmission along the inner fiber usually consists of infrared light.
There are three commonly used Fiber Optic Patch Cables sizes ,The size is measured in microns and has two components,the core diameter and the cladding diameter,For example,50/125 microns fiber cable has a core diameter of 50 microns and a cladding diameter of 125 micron.T he other two commonly used sizes are 62.5/125-micron fiber cables and 100/140-micron cable.All three types of cable have multimode transmission capability and 100/140-micron cable.All three types of cable have multimode transmission capability,which means that multiple light waves can be transmitted on the cable at once.The most commonly used size for multimode cable application is 62.5/125.
The cable core carries optical light pulses as transmitted by laser or light-emitting diode devices.The glass cladding is intended to reflect light back into the core,Fiber Optic Patch Cables is capable of handling high-speed network transmissions from 100 Mbps to over 100 Gbps.It is used in cable-plant backbones,such as between floors in a building between buildings,and beyond, the fiber backbone between floors in a building is sometimes called a fat pipe because it has a wide bandwidth for high-capacity baseband and broadband communications.
Fiber Optic Patch Cables in a campus environment is to connect separate buildings to adhere to IEEE cabling specifications.Fiber Optic Patch Cables allows use in WAN and telecommunications systems to join LANs across large geographic areas.An advantage of Fiber Optic Patch Cables is that its high bandwidth and low attenuation enable it or it to sustain transmissions over long distances.
Because the data travels by means of optical light pulses ,there are no EMI or RFI problems associated with this Fiber Optic Patch Cables ,and data transmission is purely digital instead of analog,Compare this to copper wire-based coax and twisted pair cable,both of which can experience problems with EMI or RFI,a distinct disadvantage of these mediums.However,both coax and twisted part can be used for either analog or digital communications,which, in some situations,can be an advantage over ditital-based, Fiber Optic Patch Cables.
Another advantage of Fiber Optic Patch Cables over coax and twisted-pair cable is that it is very difficult for someone to place unauthorized taps into Fiber Optic Patch Cables; the cable is fragile, and installation requires a high level of expertise.Disadvantages of this cable are that it is very fragile, is relatively expensive, and requires specialize training to install.
