Fiber optic patch cable, often called fiber optic patch cord or fiber jumper cable, is a fiber optic cable terminated with fiber optic connectors on both ends. It has two major application areas: computer work station to outlet and fiber optic patch panels or optical cross connect distribution center. Fiber optic patch cables are for indoor applications only.
Types of fiber optic patch cables
Fiber optic patch cables can be divided into different types based on fiber cable mode, cable structure, connector types, connector polishing types and cable sizes.
Fiber optic patch Cable Mode:
1. Single mode fiber patch cables: Single mode fiber optic patch cables use 9/125 micron bulk single mode fiber cable and single mode fiber optic connectors at both ends. Single mode fiber optic cable jacket color is usually yellow. Here is the explanation of what is single mode and single mode fiber.
2. Multimode fiber patch cables: Multimode fiber optic patch cables use 62.5/125 micron or 50/125 micron bulk multimode fiber cable and terminated with multimode fiber optic connectors at both ends. Multimode fiber optic cable jacket color is usually orange. Here is the explanation of what is multimode and multimode fiber.
3. 10gig multimode fiber optic patch cables: 10Gig multimode fibers are specially designed 50/125 micron fiber optimized for 850nm VCSEL laser based 10Gig Ethernet. They are backward compatible with existing network equipment and provide close to three times the bandwidth of traditional 62.5/125 multimode fibers. 10 Gigabit is rated for distances up to 300 meters using 850nm Vertical Cavity Surface Emitting Lasers (VCSEL). 10Gig fiber optic cable jacket is usually aqua.
Fiber patch Cable Structure:
1. Simplex fiber optic patch cables: Simplex fiber patch cable has one fiber and one connector on each end.
2. Duplex fiber optic patch cables: Duplex fiber patch cable has two fibers and two connectors on each end. Each fiber is marked “A” or “B” or different colored connector boots are used to mark polarity.
3. Ribbon fan-out cable assembly: For ribbon fan-out cable assembly, one end is ribbon fiber with multi fibers and one ribbon fiber connector such as MTP connector (12 fibers), the other end is multi simplex fiber cables with connectors such as ST, SC, LC, etc.
