Comparison Of Single Mode And 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.

Comparison of single mode and multimode fiber.

A single mode fiber is better for longer distances than a multimode fiber. Both fiber patch cords have the same basic structure. Multimode fibers have a greater bandwidth than single mode fibers. 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.

Multi mode fiber is used primarily for short distance narrowband applications such as ethernet and cable tv. A single mode fiber is uses a thinner core than a multimode fiber. This is because it is the optics that dominates the total cost of a network system. Multi mode single mode fiber the comparison.

In comparison a multimode fiber is ideal for local networks due to its low cost. Single mode lasers are required to generate a narrow spectral width. This is coated with a pvc or lszh low smoke zero halogen sheathing. Single mode fiber cabling system is suitable for long reach data transmission applications and widely deployed in carrier networks mans and pons.

Multi mode fiber has a larger diameter core typically 50 or 62 5um. The equipment used for communications over multi mode optical fiber is less expensive than that for single mode optical fiber. 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. Around the fiber two layers of fabric and or plastic for the insulation and protection of the fiber are placed.
