Detailed explanation-1: -Multimode connections are ideal LAN, security systems, and other fiber networks for high speed communications over shorter distances. Fiber optic cabling is the most expensive of the three types of cabling.
Detailed explanation-2: -Singlemode fibre has a much smaller core size of 9 microns and has a single light path and can travel much longer distances of up to 100km. These require more expensive electronics which operate in the 1310 and 1550nm windows and are typically used in longer distance LAN’s, Cable TV and telephony applications.
Detailed explanation-3: -The short version: Fiber is faster, more reliable, and more expensive. Cable is slower, but it still supports fast speeds and is more widely available.
Detailed explanation-4: -Single mode systems are generally more expensive. Multimode fiber has a larger core and is recommended for fiber runs less than 400 m (1300 feet). The grade of multimode fiber affects its distance and bandwidth capabilities. Multimode systems are generally less expensive.
Detailed explanation-5: -Overall, fiber internet tends to be a better value than cable internet. Although cable offers the cheapest internet plans, fiber optic offers significantly faster upload and download speeds for only a few dollars more each month.
