Patchcords are used to cross-connect installed cables and connect communications equipment to the cable plant. The choice of patchcords is very important to the performance of the network. Choose patchcords with these criteria:
• Fiber type must match the type of fiber in the cable plant. For multimode cable, use only 50/125 patchcords with 50/125 fibers in cables and 62.5/125 patchcords with 62.5/125 fibers in cables. Although there are several types of each size fibers, matching the fiber type exactly is generally not required, e.g you can use OM3 patchcords on OM2 or OM4 cable plants. Singlemode fiber is mostly the same, but some long distance fibers have different mode field diameters and should use patchcords with matching fibers. Some patchcords are made from special bend-insensitive fibers. Although there has been some controversy about the compatibility of BI fibers to normal fibers, manufacturers seemed to have adapted their designs to ensure compatibility.
• Choose patchcords with proper cable jacket color codes. This can help prevent mismatching fibers, especially multimode fibers.
• Choose patchcords with the correct matching connectors. Choose connector types that match the connectors on patch panels and equipment. Since many cable plants use one type of connector and the equipment another, e.g. STs on a multimode cable plant and LCs on the equipment, you may need to stock hybrid patch cables with different connectors on each end to make the connection. For singlemode networks, the connectors must also have the proper finished ferrule ends, either PC or ultra PC polish for most systems or angled PC (APC) connections for higher speed systems or those carrying AM video. Do not mix PC and APC connectors as that may damage them! The TIA 568 color code for connector bodies and/or boots is Beige for multimode fiber except aqua for laser-optimized fiber, Blue for singlemode fiber, and Green for APC (angled PC) connectors.

FO patch cords are mainly used in patch panels or as connections between outlets and terminals. Duplex cables with duplex connectors prevent from changing transmission and reception lines. The quality of connectors and fibers used determines to a great degree the insertion loss and reflexion performance of the transmission line. Factory- assembled FO patch cables guarantee exceptional optical and mechanical characteristics and a long lifetime due to use of optimized components and a constantly controlled manufacturing process. Flame-retardant and halogen-free cable sheath material provides low environmental load.
Corning offers the most complete line of connectors and factory-terminated cables, from single-fiber jumpers to high-fiber-count assemblies. As the industry’s leading supplier of cable assemblies, Corning’s state-of-the-art manufacturing process ensures unsurpassed connector performance with products that meet or exceed all industry standards for reflectance and insertion loss. Highly trained and qualified associates thoroughly inspect the incoming fibers and ferrules, assemble and polish them using a carefully monitored and controlled process. The assemblies undergo rigorous performance testing to ensure optimal quality in every connector.
Corning’s preterminated assemblies use only high-quality Corning optical fibers to ensure total performance quality
