We should pay attention to when using optic fiber cables

Fiber-optic cable is available in two varieties: single-mode or multimode. The term mode refers to the bundles of light that go into the fiber-optic cable. Single-mode fiber(SMF) cable uses merely a single mode of light to propagate with the fiber cable, whereas multimode fiber allows multimode (paths) of sunshine to propagate simultaneously. In multimode fiber-optic cable, the sunshine bounces off the cable walls as it travels with the cable, which causes the signal to weaken faster.

When we are within the connection of optical fiber cable, you have to be taken into account at the ends of the connection of jump line in the ends of the joint type equipment and jump line interface type. Such as UPC LC to APC ST fiber patch, this kind fiber patch cord with yellow, joints and cases in blue; Transmission distance is more than the other, so we need choose Corresponding connectors and patch cables, they’re respectively sc, lc.

However An optical fiber connector terminates no more an optical fiber. A number of optical fiber connectors can be found. The main differences one of the types of connectors are dimensions and techniques of mechanical coupling. Generally, organizations standardize on a single kind of connector, with respect to the equipment they commonly use, or they standardize per type of fiber(one for MMF, one for SMF). Considering all the generation of connectors, about 70 connectors types are in use today.

There are literally a large number of fiber-optic connectors available because it seemed that every produce wanted its proprietary design to become "standard." Three of the very most commonly-used noes are ST connector, SC connector, LC connector, other fiber connectors like the ferrule connector (FC) and sub-miniature A (SMA) are not popular in LAN and WAN deployments. Obsolete connectors include biconic and D4 connectors. And today the ST on the right has been the most popular. Today most ethernet fiber optic interfaces come equipped for that SC around the left.

Because light are only able to travel in one direction over optical fiber, two fibers have to support full-duplex operation. Therefore, fiber-optic patch cables bundle together two optical fiber cables and terminate all of them with a pair of standard single-fiber connectors. Some fiber connectors accept both the transmitting and receiving fibers in one connector, referred to as a duplex connector.

Fiber patch cords are needed for interconnecting infrastructure devices. For instance, common patch cords include: LC ST duplex patch cord, sc-sc multimode patch cord, single mode SC ST fiber patch cable, st-lc multimode patch cord and sc-st single mode patch cord. And We must note that after while using optic patch cable we must use cases to guard the fiber optic connectors, because of dust and oil pollution can damage the optical fiber coupling. Also notice the use of color to distinguish between single-mode and multimode patch cords, The TIA-598 standard recommends the use of a yellow jacket for single-mode fiber cables and an orange(or aqua) jacket for multimode fiber cables.
