Multimode Fiber Optic Cable Transmission Distance

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 optic cable transmission distance.

Multimode fiber is usually 50 125 and 62 5 125 in construction. The 62 5 125 µm aka. When making a decision between single mode and multimode fiber cables the first factor to consider is the fiber distance which you need actually. For example in a data center multimode fiber cables are enough for the distance of 300 400 meters.

Even tiny dust particles or debris can cause issues with signal transmission. Multimode fiber distance and bandwidth. 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. Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber.

Single mode fiber optics have a significantly smaller core than multimode fiber does. 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. Designed for short distance communication a multimode fiber cable typically allows light signals to travel up to 1 2 miles. 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. Which should i choose. 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. 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.

With a 9 micron diametral core single mode cables must be kept extremely clean. Fiber optic transceiver light source. The maximum transmission distance for mmf cable is around 550m at the speed of 10git s. Optical signals are sent through the.

On the other hand chromatic dispersion affects the transmission distance of single mode fiber. This means that the core to cladding diameter ratio is 50 microns to 125 microns and 62 5 microns to 125 microns. This attributes to why single mode has better signal transmission that multimode fiber. Single mode vs multimode fiber.

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. Om1 cable will support 1000base sx out to 275 meters and that distance jumps to 550 meters with om2 cable.
