Multimode Fiber Specifications

Usually the diameter of the multimode fiber is either 50 125 µm or 62 5 125 µm.

Multimode fiber specifications.

Multimode fibers are identified by the om optical mode designation and their specifications are outlined by the iso iec 11801 standard. At present there are four kinds of multi mode fibers. Optical specifications dimensional specifications glass geometry coating geometry core diameter 50 0 2 5 μm cladding diameter 125 0. This section will review the more technical naming conventions and specifications for both multimode and single mode fiber.

Multimode fibers are described by their core and cladding diameters. This means that the core to cladding diameter ratio is 50 microns to 125 microns and 62 5 microns to 125 microns. Each has a common cladding diameter 125 microns but different core diameters 50 microns and 62 5 microns. The cisco 10gbase lrm module supports link lengths of 220m on standard fiber distributed data interface fddi grade multimode fiber mmf.

At present there are four commonly used om multimode fibers. The letters om stand for optical multimode. The diameter of the multi mode fiber is either 50 125 µm or 62 5 125 µm. Multimode fibers om1 om2 om3 om4 and om5.

Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber. Two popular sizes of multimode fiber exist today for use in commercial applications. Multimode fibers are described by their core and cladding diameters. Some types are single mode and some types are multimode.

Multimode fiber is usually 50 125 and 62 5 125 in construction. Multi mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion. Clearcurve om2 om3 and om4 multimode fiber is designed to withstand tight bends and challenging cabling routes with substantially less signal loss than conventional multimode fiber. 50 micron and 62 5 micron.

Multi mode optical fiber is a type of optical fiber mostly used for communication over short distances such as within a building or on a campus. Om1 om2 om3 and om4. Several standards address both sizes to varying degrees of depth. To make sure that specifications are met over fddi grade om1 and om2 fibers the transmitter should be coupled through a mode conditioning patch cord.

Usually we see single mode and multimode fiber types available on the market. Multi mode links can be used for data rates up to 100 gbit s.
