The cladding diameter of single mode and multimode fiber is 125 µm.
Multimode fiber cable diameter.
Om2 is a standard for multimode cable defined by iso iec 11801.
The fiber core of single mode cable is very narrow so the light that passes through these fiber optical cables is not reflected too many times which keeps the attenuation to a.
Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber.
Multimode fibers are described by their core and cladding diameters.
Om1 om2 om3 and om4.
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.
Multi mode links can be used for data rates up to 100 gbit s.
Om1 and om2 are both orange jacketed cable and you cannot judge from the outer diameter to identify om1 and om2 fiber cable.
Usually we see single mode and multimode fiber types available on the market.
There are different types of fiber optic cable.
The size of the optical fiber is commonly referred to by the outer diameter of its core cladding and coating.
Fiber optic cable can be divided into several types.
The attenuation of multimode fiber is higher than sm fiber because of its larger core diameter.
Multimode fiber is usually 50 125 and 62 5 125 in construction.
Usually the diameter of the multimode fiber is either 50 125 µm or 62 5 125 µm.
Some types are single mode and some types are multimode.
At present there are four kinds of multi mode fibers.
50 125 250 indicates a fiber with a core of 50 microns cladding of 125 microns and a coating of 250 microns.
This means that the core to cladding diameter ratio is 50 microns to 125 microns and 62 5 microns to 125 microns.
