1. SMF = Single-mode fiber.
2. The recommended mimimum range is stated in all cases where the maximum
transmitter output power exceeds the receiver’s saturation level. This is to prevent
blinding or burning out of the optical receiver on the far-end mode.
3. Distance is calculated based on ideal situations without any other loss factor.
