Multimode Mode Fiber Distance 10gb

10 gigabit ethernet fiber design considerations.

Multimode mode fiber distance 10gb.

If a project requires an extended transmission distance om4 multimode is a fitting option. This is where distance considerations really come into play. As a rule of thumb it is recognized as 400 m. Key factors to consider in the design of 10 gigabit ethernet networks are.

Single mode smf and multi mode mmf. In smf light follows a single path through the fiber while in mmf it takes multiple paths resulting in differential mode delay dmd. If you had sfp 10g lr long reach than you would have to use single mode fiber. But it still can achieve up to 550 m if the om4 fiber has an ultra high quality.

From the chart we can see that single mode fiber distance is much longer than that of multimode fiber cables at the data rate from 1g to 10g but om3 om4 om5 multimode fiber supports a higher data rate. The network topology including operating distances splice losses and numbers of connectors i e. This usually makes it the prime option for 10 gigabit ethernet over multimode fiber applications. Sfp 10g lr single mode fiber.

Furthermore om3 and om4 fibers both support speeds of 40 gb s and 100 gb s. 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 has been the most popular multimode fiber choice throughout the 80 s 90 s and into the early 2000 s and was the most common multimode fiber used and yet it has the lowest data carrying capacity and shortest distance limitations as compared with other multimode fiber types. Smf is used for long distance communication and mmf is used for distances of less than 300 m.

Om3 multimode fiber is specifically made for 10g ethernet transmission. There are two basic types of optical fiber used for 10 gigabit ethernet. Speed gbps maximum distance meters by optical media type. The 62 5 125 µm aka.

Multi mode links can be used for data rates up to 100 gbit s. The fiber cabling type i e. The link power budget. But the maximum transmission distance of om4 under 10g remained controversial.

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. Yes sr in the part number stands for short reach and that is used with multimode fiber.
