Comparison of single mode and multimode fiber.

A single mode fiber is better for longer distances than a multimode fiber. The equipment used for communications over multi mode optical fiber is less expensive than that for single mode optical fiber. A single mode fiber is uses a thinner core than a multimode fiber. This page on single mode vs multimode fiber describes difference between single mode and multi mode fiber systems the other difference between terms are also provided.

Single mode fiber cabling system is suitable for long reach data transmission applications and widely deployed in carrier networks mans and pons. Multimode fibers have a greater bandwidth than single mode fibers. Both fiber patch cords have the same basic structure. Multi mode fiber is used primarily for short distance narrowband applications such as ethernet and cable tv.

Single mode fiber cable systems are usually more expensive even though the actual cost of single mode fiber cable is cheaper than that of multimode fiber cable in the market. These are significantly more expensive than their lower spec multi mode counterparts. Single mode lasers are required to generate a narrow spectral width. Typical transmission speed and distance limits are 100 mbit s for distances up to 2 km 1 gbit s up to 1000 m and 10 gbit s up to 550 m because of its high capacity and reliability multi mode optical fiber generally is used for backbone applications.

In comparison a multimode fiber is ideal for local networks due to its low cost. Multi mode fiber has a larger diameter core typically 50 or 62 5um. This is because it is the optics that dominates the total cost of a network system. Multi mode single mode fiber the comparison.
