Multimode fiber is mostly used for communication over short distances like inside a building or on a field. • Light waves are discrete into several paths or modes, as they travel through the cable core. • Multimode links may be used for data rates up to 100 Gbps. • Multimode fiber core diameter is from 50 micrometers to 62.5 micrometers. • The most transmission distance for MMF cable is around 550m at the speed of 10Gb/s. It will transmit farther at lower data rates, like going about 2km at 100Mb/s.

3. Multimode fiber optic cables may be classified into OM1 fiber,
OM2 fiber, OM3 fiber, OM4 fiber, and recently released OM5
fiber.
TYPESOF MULTIMODE FIBER

4. OM1 cable usually comes with an associated orange jacket and includes a core size of
62.5 micrometers (µm). It will support ten Gigabit LAN at lengths up to 33 meters. It's most
typically used for 100 unit LAN applications.
OM2 conjointly includes an instructed jacket color of orange. Its core size is 50µm rather than
62.5µm. It supports 10 Gigabit LAN at lengths up to 82 meters, however, is additionally
normally used for 1 Gigabit LAN applications. Both OM1 and OM2 work well with LED-based
instrumentality which will send many modes of light down the cable.
OM3 includes an instructed jacket color of aqua. Like OM2, its core size is 50µm, but the
cable is enhanced for laser-based equipment that uses fewer modes of light. As a result of this
improvement, it's capable of running 10 Gigabit LAN at lengths up to 300 meters. Since its
origination, production techniques have improved the general capabilities of OM3 to modify its
use with 40 Gigabit and a 100 Gigabit LAN up to a 100 meters. 10 Gigabit LAN is its most
common use.
OM4 conjointly includes an instructed jacket color of aqua. it's an extra improvement to OM3.

5. TECHNICAL
Multimode fiber optic cable includes a large diametral
core(50 to 100 microns) that permits multiple modes of
light to propagate.
BANDWIDTH
Multimode fiber accommodates roughly 1 GHz of
bandwidth, which is much less than single mode,
however acceptable for many audio, video, and data
transmissions.
MULTIMODE FIBER CONNECTOR
TYPES
Multimode fiber connection varieties in circulation such as
ST, SC, FC, LC, MTP & MPO, etc. the most normally used
fiber optic connector types include ST, SC, FC, and LC.

6. FEATURES OF MULTIMODE FIBER
Multimode fiber contains a core with a bigger diameter than single-
mode fiber.
Lasers or LEDs (Light-Emitting Diodes) generated lightweight pulses to
travel at totally different angles.
It has larger attenuation than single-mode fiber.
Modal distortion is the offensively downside of a multimode fiber.
Multimode is healthier for long distances.
