Fiber optic patch cables are the most commonly used components in fiber optic network, capped at either end with connectors that allow it to be rapidly and conveniently connected to CATV, an optical switch or other telecommunication equipment. Its thick layer of protection is used to connect the optical transmitter, receiver, and the terminal box. Sometimes fiber optic patch cables are also called fiberoptic jumpers or fiber patch cords. They are the backbone of the fiber optics industry. These fiber patch cables are strands of optically pure glass as thin as human hair. And these cables carrying information is via mode of transmission of light. Short patch leads usually made with stranded wire are flexible patch cables. Classification Fiber patch cable can be classified by transmission medium (long or short distance), by connector construction and by construction of the connector’s inserted core cover. Single mode and multimode are classified by transmission medium, which are the two common types of fiber patch cable. While FC, SC, ST, LC, MTRJ, MPO, MU, SMA, FDDI, E2000, DIN4, and D4 Cables are classified by the connectors oneither end of the cable. For most of the patch cables, the SC, ST, FC, LC, MU, MTR, E2000 connectors (APC/UPC polish) are all available. Next I will give you a clear introduction to the single mode fiber patch cable and multimode fiber patch cables. Single mode Fiber Patch Cable Single mode fiber patch cable is generally yellow, with a blue connector, and a longer transmission distance. Which has a small core and only one pathway of light. With only a single wavelength of light passing through its core, single mode realigns the light toward the center of the core instead of simply bouncing it off the edge of the core as with multimode. Single mode cable features a 9 micron glass core. single mode fiber patch cable is typically used in long haul network connections spread out over extended areas—longer than a few miles. Multimode Fiber Patch Cable Multimode fiber patch cable is generally orange or grey, with a cream or black connector, and a shorter transmission distance, which has a large diameter core that is much larger than the wavelength of light transmitted, and therefore has multiple pathways of light several wavelengths of light are used in the fiber core. Multimode cable comes with two different core sizes: 50 micron or 62.5 micron. Multimode fiber optic patch cord can be used for most general fiber applications. Use multimode fiber for bringing fiber to the desktop, for adding segments to your existing network, or in smaller applications such as alarm systems. Application Fiber patch cables are used in two major application areas:computer work station to outlet and patch panels or optical cross connect distribution center. They are utilized in Medical Imaging, Mechanical Engineering, LAN Applications, CATV Networks, Telephone Lines, etc. They have revolutionized the total network industry of telephones, cable, internet, audio applications, etc. The fiber patch cables offer accurate signal transfer that is totally distortion free. As these fiber patch cables use light as a mode of transmission, there isn’t any hazard of electric interference or any tampering. After going through this passage, I think you have got many information about fiber optic patch cables.
