Single Mode And Multimode Optical Fiber Cable

What is the difference between multimode and single mode fiber optic cables.

Single mode and multimode optical fiber cable.

When making a decision between single mode and multimode fiber cables the first factor to consider is the fiber distance which you need actually. Fiber optic connectors and cables are present in nearly every communications project that we might sell into be it a das installation or a base station with wireless backhaul you can be certain that fiber jumpers and cabling are being used somewhere in that network. Fiber optic cabling and hardware products including single mode and multimode fiber patch cables of 62 5 125 50 125 and 9 125 and fiber distribution products used in high tech networking. Single mode fiber optic cable.

A fiber internet connection is a fast and reliable way to transmit data across a network. Which should i choose. 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. Single mode and multimode optical fibers have their own area where they excel.

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. The equipment used for communications over multi mode optical fiber is less expensive than that for single mode optical fiber. This is because it is the optics that dominates the total cost of a network system. A single mode fiber is uses a thinner core than a multimode fiber.

Single mode vs multimode fiber. Single mode cables are designed to carry light directly down the fiber. In comparison a multimode fiber is ideal for local networks due to its low cost. It is a single strand of glass fiber and has a diameter of 8 5 10 microns.

Because it has one mode of transmission it will propagate 1310 or 1550 nm. For example in a data center multimode fiber cables are enough for the distance of 300 400 meters. Because of this the number of light reflections created as the light passes through the core decreases lowering attenuation and creating the ability for the signal to travel further. Single mode fibers are better for moving information across great distances and are routinely used by telecoms.

Single mode fiber optic cable has a small diametral core that allows only one mode of light to propagate.
