The jumper of the optical module, namely the fiber optic jumper used to connect the optical module, is an indispensable component in the optical communication system, used to achieve reliable optical signal transmission between the optical module and other equipment (such as fiber optic distribution frames, another optical module, etc.).
Classified by fiber type:
Single mode fiber jumper: using single-mode fiber, usually yellow in color, suitable for long-distance transmission, with transmission distances up to several kilometers or even tens of kilometers, commonly used for connecting backbone networks such as metropolitan area networks and wide area networks.
Multimode fiber jumper: Using multimode optical fiber, usually in orange or navy blue color, with a relatively short transmission distance, usually within a few hundred meters, but with high bandwidth, it is suitable for use in short distance high-speed communication scenarios such as data centers and campus networks.
Classified by connector type:
LC fiber optic jumper: small in size and high in density, widely used in high-speed network equipment and data centers, such as optical module connections for servers and switches.
SC fiber optic jumper: square structure, easy to plug and unplug, commonly used in telecommunications, cable television and other networks.
ST fiber optic jumper: a circular clip on structure that was widely used in early fiber optic networks, but was gradually replaced by other types of connectors due to its inconvenient insertion and removal. However, it is still used in some old network systems.
FC fiber optic jumper: using threaded connection method, with good stability, commonly used in fiber optic communication equipment, testing instruments, etc. It is also applied in fields such as military and aerospace that require high stability.
Jumper characteristics
Low loss: High quality fiber optic jumpers have extremely low optical signal transmission loss at specific wavelengths, ensuring that optical signals maintain high strength and quality during long-distance transmission, reducing the impact of signal attenuation on communication quality.
High bandwidth: capable of supporting high data transmission rates to meet the growing demand for high-speed communication, such as 10Gbps, 40Gbps, 100Gbps, and even higher speeds.
Good flexibility: Fiber optic jumpers have a certain degree of flexibility, making them easy to bend, lay, and install in different wiring environments, and can adapt to various complex network layouts.
Anti electromagnetic interference: Since optical fibers transmit data based on optical signals and are not affected by electromagnetic interference, they can also stably and reliably transmit data in strong electromagnetic environments (such as near substations and communication base stations).
Adaptation to optical modules
The jumper of the optical module needs to match the optical interface type and fiber type of the optical module. For example, if the optical interface of the optical module is an LC interface, a fiber optic jumper with LC connectors on both ends needs to be used to connect it; If the optical module uses single-mode fiber for signal transmission, it must be paired with single-mode fiber jumpers. In addition, the transmission rate and wavelength parameters of the optical module also affect the selection of jumpers. It is important to ensure that jumpers can support the working rate and wavelength range of the optical module to achieve optimal communication performance.
Applications
Data center: Optical modules used to connect servers, storage devices, switches, and other devices, building a high-speed and reliable internal network to achieve fast data transmission and exchange. A large number of fiber optic jumpers are required between different racks and data center facilities on different floors to connect optical modules and ensure efficient operation of the data center.
Communication network: In the backbone network, metropolitan area network, and access network of telecommunications operators, fiber optic jumpers are used to connect various optical modules of optical communication equipment, such as optical transmission equipment, base stations, etc., to achieve long-distance transmission and access of voice, data, video and other services.
Enterprise network: Within the enterprise park, optical modules are connected through fiber optic jumpers between office buildings, factories, and other buildings, as well as between different floors and rooms inside the buildings, to form a high-speed and stable park network that meets the communication needs of enterprise employees for office, production, and other purposes.
Fiber to the home (FTTH): In the home broadband access scenario, the fiber jumper is used to connect the optical module in the optical distribution box in the corridor and the optical network terminal (ONT) equipment in the user’s home, introduce the fiber signal into the home, and provide users with high-speed Internet access services.
