Relationship between wavelength and optical cable
Fiber optic transmission wavelengths are determined by two factors: longer wavelengths in the infrared for lower loss in the glass fiber and at wavelengths which are between the absorption bands. Wavelength and frequency are related, so some radiation is identified by its wavelength while others are referred to by their frequency. This article delves into why 850, 1310, and 1550 nm are standard, what less-known regimes and tradeoffs. Bandwidth refers to the capacity of a fiber optic cable to transmit data — much like the width of a highway determines how many vehicles can pass through at once.
