What are single-mode and multimode fibers? What are the pros and cons?

Singlemode Fiber: Single mode optical fiber can only transmit in a given working wavelength.

Advantages: The transmission bandwidth of single mode fiber is wide and the transmission capacity is large. Optical signal can be transmitted along the axial direction of light, so the loss of light signal is very small, discrete is also very small, single-mode fiber backbone cabling The maximum distance of 3000m.

Cons: High prices.

Multimode fiber: multimode fiber optical signal more than one wavelength (modulus).

Advantages: Low Cost:

Disadvantage: poor transmission performance. The maximum distance for cabling is 2000M.
