Fiber Patch Cords vs Fiber Pigtails

Fiber optic patch cord and fiber optic pigtail are two commonly used components in fiber optic network. They have many things in common and they also differ in distinct ways. Knowing both the similarities and the differences between them will help you make the best selection for your project. The passage mainly talks about their similarities and differences in both structures and applications.

Structures of Fiber Patch Cords and Pigtails

Fiber patch cord, also known as fiber optic patch cable or fiber jumper cable, is a short length of optical fiber cable with a connector on each end. Connector types on each side of the fiber patch cable can be different and they can also be the same. Fiber optic pigtail is a piece of cable terminated with a fiber optic connector at only one end of the cable and leaves a length of exposed fiber at the other end, so that the connector side can link to the equipment and the other side can be melted with optical cable fibers or stripped and fusion spliced to a single fiber of a multi-fiber trunk. The following picture shows a fiber patch cord and a fiber pigtail.

Fiber optic patch cords and pigtails structurally have much in common. They are both available in single mode and multi-mode, and they can be made into simplex and duplex. Besides, both fiber patch cord and pigtail can terminate with many kinds of fiber optic connectors, including FC, SC, ST, LC, MTRJ, MPO, MU, SMA, FDDI, E2000, DIN4, and D4.

The major physical difference between fiber patch cord and pigtail is that fiber patch cord is a fixed length piece of cable with fiber connectors on each end while fiber pigtail has fiber connectors on only one end of the cable. Fiber optic patch cords can be cut into shorter lengths to make two pigtails.

Applications of Fiber Patch Cords and Pigtails

Fiber optic patch cords and pigtails provide interconnect and cross-connect of applications over installations in entrance facilities, telecommunications rooms, and data centers. They are available in OM4, OM3, OM2, OM1, or OS1/OS2 fiber types to meet the demands of Gigabit Ethernet, 10 Gigabit Ethernet and high speed Fibre Channel. However, they have their respective application areas, too.

Fiber patch cords are commonly used to connect ports on fiber distribution frames. They support network applications in main, horizontal and equipment distribution areas and are available in optical fiber riser cable (OFNR), and low smoke zero halogen (LSZH) rated jacket materials to comply with local cabling ordinances. They also support high speed (10/40 Gbs) telecommunications. Fiber optic patch cords can be used in many areas, such as integrated optics, laser detection and display, and materials processing.

Fiber optic pigtails support fusion splice field termination applications. They should be installed where they will be protected and spliced, so they are usually used with fiber optic management equipment like optical distribution frame (ODF), splice closures and cross cabinets. Pigtails are found anywhere, but most commonly in optical assemblages or optical components. There are waterproof fiber optic pigtails used for outdoor applications, which is with thick poly ethylene (PE) jacket and big diameter.

fiber-mart.com produces high quality fiber optic patch cords and pigtails using a variety of commercially available connectors and fibers. We provide various single mode and multi-mode fiber patch cords and fiber pigtails. These patch cords and pigtails offer low insertion losses, and excellent repeatability. And they can be manufactured to custom length.

How Many Types of Fiber Optic Patch Cords Do You Know?

Fiber optic patch cords are also known as “fiber optic jumper” or “fiber optic patch cables”. It’s commonly used in fiber optic network. According to the transmission medium, it can be divided into two types: single-mode fiber optic patch cords and multi-mode fiber optic patch cords. According to optical connector, it can be classified into many types, such as FC, LC, MU, SC, ST, etc.
This article will introduce the categories classified by optical connector to help you know more about them and choose what kind of fiber optic patch cords you need. An optical fiber connector enables quicker connection and disconnection than splicing by terminating the end of an optical fiber. Here are some popular fiber optic patch cords terminated with FC/LC/MU/SC/ST connectors on both ends.
FC Fiber Optic Patch Cords
FC fiber optic patch cords, for example, FC-FC multi-mode fiber patch cable, are with FC fiber optic connectors, which is a metal threaded screw type connection. FC connectors’ floating ferrule provides good mechanical isolation. FC connectors need to be mated more carefully than the push-pull types due to the need to align the key, and due to the risk of scratching the fiber end face while inserting the ferrule into the jack.
LC is short from “Lucent Connector”. LC fiber patch cord connector is a push and latch structure, with plastic housing and accurate 1.25mm ceramic ferrule. LC type is a popular kind of small form fiber optic patch cord which reduces the space and it is widely used for densely installation, such as LC-LC Fiber Patch leads.
MU Fiber Optic Patch Cords
MU fiber optic patch cord is also the invention of NTT in Japan. MU is a small size fiber optic patch cord with plastic housing and a push pull structure. MU fiber optic connector is similar size of LC. It’s designed for high-density connections and provides more than double the packaging density of the SC connector.
SC Fiber Optic Patch Cords
SC fiber optic patch cord was invented by the Japanese company NTT. It’s one of the most widely used fiber optic patch cords because it has advantages of low cost, simplicity and durability. SC fiber optic patch cords are with a locking tab on the cable termination. It is a push and pull type fiber optic connector with excellent packing density.
ST Fiber Optic Patch Cords
ST fiber optic patch cords are with straight tip type terminations. There is only simplex ST fiber optic patch cords and no duplex ones. ST fiber optic connectors, widely used for multi-mode networks, are usually with a metal housing, although there is plastic housing.
