Fiber Loopback for Efficient Fiber Optic Testing
Loopback mainly refers to a kind of test method eight by hardware of software to test physical connection problems in a fiber optic network. Loopback test is realized by feeding a received signal or data back to the sender. A fiber loopback, as a media of return patch for a fiber optic signal, is widely used for fiber optic testing, fiber network repair and fiber optic equipment diagnosis. It is the idea tool for fiber optic testing or resolving equipment failures.
A fiber optic loopback consist of fiber loopback connectors and loopback cables. According to the structures of the fiber loopback, the fiber optic connector type and the fiber mode of the fiber cable, the fiber optic loopback can be divided into different types. Bellowing is the details about the classification of the fiber loopback.
Structures
According to the structure of a fiber loopback, there are fiber optic loopback cables and fiber optic loopback molded loopback, fiber loopback module, fiber optic loopback adapter – the same item different names.
The fiber optic loopback cable is also the traditional fiber optic loopback, it is consist of two connectors on a same piece of simplex fiber optic patch cable, forming a loop.
The molded fiber optic loopbacks is the compacted sized fiber optic loopback cable. The molded loopback use an outer enclosure to protect it and from the outside you do not see the optical cables, they are more compacted size and stronger then the fiber loopback cables.
Connector types
Based on the optical connector types on the loopback, there are SC, LC, MTRJ, ST, FDDI etc. The most commonly used fiber optic loopbacks are SC and LC type.
Optical fiber types
According to the optic fiber mode type of the loopback cable, there are single mode 9/125 fiber optic loopbacks, 10G multimode loopback, multimode 50/125 fiber optic loopbacks and 62.5/125 fiber optic loopbacks. 10G loopback module is used in 10G multimode 50/125 Fiber Testing application.
Typically single mode SC type and LC type fiber optic loopbacks are blue color, typical multimode LC and SC type fiber loop backs are beige color, this also goes with the practice of fiber optic patch cables. Fiber loopback can be with various jacket types and cable diameters, length or terminations, which can be customized according to customers’ special requirements.
We offer custom fiber loopback cable with compact design, and they are compliant with fast ethernet, fiber channel, ATM and Gigabit Ethernet Each of the cables are functionally tested before shipping, and other customization for assemblies like connector configurations and special polished for the fiber optic loopbacks is also welcomed.
