But the maximum transmission distance of om4 under 10g remained controversial.
Multimode mode fiber distance 10gb.
The fiber cabling type i e.
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.
When it managers require distances upwards of 860 meters they will likely want to consider single mode cable instead of multimode 10 gb s networksmany enterprise networks are moving beyond 1000base sx and transitioning to 10 gigabit networks such as 10gbase sr.
Om4 fiber distance is longer than om3 fiber distance based on 10 40 and 100 gb s.
Om3 multimode fiber is specifically made for 10g ethernet transmission.
This usually makes it the prime option for 10 gigabit ethernet over multimode fiber applications.
As a rule of thumb it is recognized as 400 m.
If a project requires an extended transmission distance om4 multimode is a fitting option.
Smf is used for long distance communication and mmf is used for distances of less than 300 m.
But it still can achieve up to 550 m if the om4 fiber has an ultra high quality.
10 gigabit ethernet fiber design considerations.
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.
Key factors to consider in the design of 10 gigabit ethernet networks are.
There are two basic types of optical fiber used for 10 gigabit ethernet.
If you had sfp 10g lr long reach than you would have to use single mode fiber.
In smf light follows a single path through the fiber while in mmf it takes multiple paths resulting in differential mode delay dmd.
Yes sr in the part number stands for short reach and that is used with multimode fiber.
Single mode or multimode fiber and the performance at a specified.
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.
Single mode smf and multi mode mmf.
This is where distance considerations really come into play.
The network topology including operating distances splice losses and numbers of connectors i e.
The link power budget.
Multi mode links can be used for data rates up to 100 gbit s.
Speed gbps maximum distance meters by optical media type.
