Multimode Fiber Optic Cable Transmission Distance

Because of this more data can pass through the multimode fiber core at a given time.

Multimode fiber optic cable transmission distance.

What s happening inside the multimode fiber. Single mode fiber optics have a significantly smaller core than multimode fiber does. 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. When making a decision between single mode and multimode fiber cables the first factor to consider is the fiber distance which you need actually.

This attributes to why single mode has better signal transmission that multimode fiber. The following chart lists the transmission distance of smf and mmf at different fiber optic cable speeds. Typically the multimode fiber optic cable speed and the transmitting distance limits are 100 mbit s for distance up to 2 km 100base fx gbit s up to 1000m and 10 gbit s up to 550 m. Om1 cable will support 1000base sx out to 275 meters and that distance jumps to 550 meters with om2 cable.

Multimode fiber distance and bandwidth. On the other hand chromatic dispersion affects the transmission distance of single mode fiber. Fiber optic transceiver light source. Which should i choose.

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. Multimode fiber is usually 50 125 and 62 5 125 in construction. For example in a data center multimode fiber cables are enough for the distance of 300 400 meters. Multi mode links can be used for data rates up to 100 gbit s.

The 62 5 125 µm aka. With a 9 micron diametral core single mode cables must be kept extremely clean. The maximum transmission distance for mmf cable is around 550m at the speed of 10git s. Multimode fiber optic cable has a larger core typically 50 or 62 5 microns that enables multiple light modes to be propagated.

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. Single mode vs multimode fiber. Fibre optic cable transmission distances when chosing a fibre optic cable for a permanent trunk link you should consider three things 1 what is the distance of the cable run 2 what bandwitdh do i require now 3 what might i need in 5 10 or 15 years time iw what future proofing do i.

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. Even tiny dust particles or debris can cause issues with signal transmission.
