Distance from Australia to fiber optic cable
The Pacific Fibre Cable System is a new generation trans-pacific subsea fiber optic cable linking Australia, New Zealand and the US. The answer depends on several interrelated factors — fibre type, cable standard, the light wavelength in use, and the optical transceivers connected to it. Attenuation is the weakening of light as it comes in from the transmitting end of the fiber and out of the transmitting end. However, fiber cable runs are not limitless. Beginning with optical ground wire (OPGW), introduced in 1984 as AFL's flagship product, the line now spans to fibre optic cabling solutions being used in the world's harshest environments, including those above ground, below ground and. The distance in fiber optics is calculated using the following formula: [ text {Distance (km)} = frac {text {Speed of Light in Fiber (km/s)} times text {Round-Trip Time (s)}} {2} ] Where: Speed of Light in Fiber ≈ 200,000 km/s (depends on the refractive index of the fiber).
