• Typical Distances: 4 km for multi - mode, 5 km for single - mode (40 km), and 80 km for single - mode (80 km).

• Wavelengths: The typical wavelength is 1300 nm for multi - mode, 1310 nm for single - mode (40 km), and 1550 nm for single - mode (80 km). The TX wavelength range is 1260 - 1360 nm for multi - mode, 1280 - 1340 nm for single - mode (40 km), and 1530 - 1570 nm for single - mode (80 km). The RX wavelength range is 1100 - 1600 nm for all types.

• Optical Power: The TX power range is - 10 to - 20 dBm for multi - mode, 0 to - 5 dBm for single - mode (40 km and 80 km). The RX sensitivity range is - 3 to - 32 dBm for multi - mode, - 3 to - 34 dBm for single - mode (40 km and 80 km). The link budget is 12 dB for multi - mode, and 29 dB for single - mode (40 km and 80 km). The dispersion penalty is 3 dB for multi - mode, and 1 dB for single - mode (40 km and 80 km).
