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 ( 100BASE-FX ), 1 Gbit/s up to 1000 m, and 10 Gbit/s up to 550 m.
The G.651.1 Recommendation builds on a previous fiber optic specification in G.651. G.651.1 was first published in 2007. Revisions of the standard were since published in 2008, and 2018 (November).
Fiber-optic communication is a form of optical communication for transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. [ 1 ] [ 2 ] The light is a form of carrier wave that is modulated to carry information. [ 3 ]
The standard defines several classes of optical fiber interconnect: OM1*: Multimode, 62.5 μm core; minimum modal bandwidth of 200 MHz·km at 850 nm; OM2*: Multimode, 50 μm core; minimum modal bandwidth of 500 MHz·km at 850 nm; OM3: Multimode, 50 μm core; minimum modal bandwidth of 2000 MHz·km at 850 nm
If multimode fiber bandwidth is measured using a laser diode directly coupled to its input, the resulting measurement can vary by as much as an order of magnitude. This measurement variability is due to the combination of differences in laser output characteristics (emitted mode power distribution) and the differential mode delay of the fiber.
