When a fiber optic cable is capped with connectors at both ends it is referred to as a fiber optic patch cord. The other popular name is “fiber optic jumper.” In technical terms, experts explain that there are two major parts of a fiber optic patch cords — optical connectors and fiber optic cables.

Why Fiber Optic Patch Cords

Modern Dense Wavelength Division Multiplexing (DWDM) networks require high performance connectivity to transmit data over 100 kilometers. High performance connectivity means high input optical power (i.e. +27 dBm) and low return loss (i.e. ≥55 dB). If the cord connectors are of low quality, optic fiber cable will get damaged or burned. Poor quality connectors also increase network downtime. Therefore, it is essential for telecom companies to upgrade the specifications of connectors or use fiber optic patch cord in order to maximize performance during long-distance data transmission.

Types of Fiber Optic Patch Cords

There are two types of fiber optic patch cords available on the market:

Single-mode fiber optic patch cords are generally used for telecommunication networks. They are also used for setting up access points for high-speed networks.

Multimode patch cords are used for connecting high-speed networks like ethernet, gigabit ethernet, and fast ethernet.
Unlike copper patch cords, most fiber optic patch cord cables contain a single strand of fiber, which means that data would flow only in one direction. During the fiber optic cable installation process, users need to ensure that they are using two simplex (i.e., single strand of fiber) cables for each interconnection or a duplex cable.

The fiber optic patch cords can also be classified based on the connector types. For example, when you see the name “LC fiber optic patch cord,” it means the cable is with a LC fiber optic connector. Similarly, there are MTRJ, FDDI, DIN4, MPO, FC, SC, ST, MU, SMA, E2000, DIN4, and D4 type fiber patch cords.
