Comparison Of Single Mode And Multimode 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.

Comparison of single mode and multimode fiber. In comparison a multimode fiber is ideal for local networks due to its low cost. Multi mode single mode fiber the comparison. Both fiber patch cords have the same basic structure. This is because it is the optics that dominates the total cost of a network system.

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. The equipment used for communications over multi mode optical fiber is less expensive than that for single mode optical fiber. Multi mode fiber is used primarily for short distance narrowband applications such as ethernet and cable tv. Multi mode fiber has a larger diameter core typically 50 or 62 5um.

A single mode fiber is better for longer distances than a multimode fiber. Single mode lasers are required to generate a narrow spectral width. These are significantly more expensive than their lower spec multi mode counterparts. 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.

Around the fiber two layers of fabric and or plastic for the insulation and protection of the fiber are placed. We will see the differences taking into consideration various comparison factors of transmission system such as data rate distance attenuation time to travel and so on. Single mode fiber cabling system is suitable for long reach data transmission applications and widely deployed in carrier networks mans and pons. This is coated with a pvc or lszh low smoke zero halogen sheathing.
