Multimode fiber cable distance.
There are two basic types of transmitters that work with multimode fiber.
850nm led and 1300 nm laser.
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.
Let s take a closer look at the types of multimode fiber options based on bandwidth and distance needs 1 gb s networksthe majority of enterprise fiber networks today still run 1000base sx delivering up to 1 gb s over multimode.
When making a decision between single mode and multimode fiber cables the first factor to consider is the fiber distance which you need actually.
Because of this more data can pass through the multimode fiber core at a given time.
Multi mode links can be used for data rates up to 100 gbit s.
Supported speeds can range from 16mbs token ring to 10gbs ethernet.
The maximum transmission distance for mmf cable is around 550m at the speed of 10git s.
Multimode fiber is usually 50 125 and 62 5 125 in construction.
Multimode fiber optic cable has a larger core typically 50 or 62 5 microns that enables multiple light modes to be propagated.
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.
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.
Multimode fiber distance and bandwidth designed for short distance communication a multimode fiber cable typically allows light signals to travel up to 1 2 miles.
Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber.
For example in a data center multimode fiber cables are enough for the distance of 300 400 meters.
Since om1 and om2 fiber can not support 25gbps and 40gbps data transmission speeds om3 and om4 were the main choices for multimode fiber to support 25g 40g and 100g ethernet.
There are three types of multimode fiber.
Speed gbps maximum distance meters by optical media type.
Om1 cable will support 1000base sx out to 275 meters and that distance jumps to 550 meters with om2 cable.
Multimode fiber accommodates roughly 1 ghz of bandwidth which is much less than single mode but sufficient for most audio video and data transmissions.
