The equipment used for communications over multi-mode optical fiber is less expensive than that for single-mode optical fiber. [1] Typical transmission speed and distance limits are 100 Mbit/s for distances up to 2 km (), 1 Gbit/s up to 1000 m, and 10 Gbit/s up to 550 m.
Structured cabling network diagram. Structured cabling is the design and installation of a cabling system that will support multiple hardware uses and be suitable for today's needs and those of the future. With a correctly installed system, current and future requirements can be met, and hardware that is added in the future will be supported. [1]
Ordinary fibers measure 125 μm in diameter (a strand of human hair is about 100 μm). The inner diameter measures 9 μm for single-mode cables, and 50 / 62.5 μm for multi-mode cables. The development of "reduced bend radius" fiber in the mid-2000s, enabled a trend towards smaller cables.
Glass fiber optic connector performance is affected both by the connector and by the glass fiber. Concentricity tolerances affect the fiber, fiber core, and connector body. The core optical index of refraction is also subject to variations. Stress in the polished fiber can cause excess return loss. The fiber can slide along its length in the ...
A fiber media converter is a simple networking device that makes it possible to connect two dissimilar media types such as twisted pair with fiber optic cabling. They were introduced to the industry in the 1990s, and are important in interconnecting fiber optic cabling-based systems with existing copper-based structured cabling systems.
A multi-mode optical fiber has a larger core (≥ 50 micrometers), allowing less precise, cheaper transmitters and receivers to connect to it as well as cheaper connectors. However, a multi-mode fiber introduces multimode distortion, which often limits the bandwidth and length of the link.
The switching or reconfiguration functions range from the manual fiber patch panel to a variety of switching technologies including microelectromechanical systems (MEMS), liquid crystal and thermo-optic switches in planar waveguide circuits. Although both have add/drop functionality, OADMs are distinct from add-drop multiplexers.
A fiber pigtail is a single, short, usually tight-buffered, optical fiber that has an optical connector pre-installed on one end and a length of exposed fiber at the other end. The end of the pigtail is stripped and fusion spliced to a single fiber of a multi-fiber trunk. Splicing of pigtails to each fiber in the trunk "breaks out" the multi ...
