200 (HCS) 0.37 6 19.2 8500 ft (2600 m)
Maximum length is calculated with:
b Minimum optical power available
b Maximum fiber attenuation
b Losses in two ST connectors: 0.6 dBm
b Optical power margin: 3 dBm (according to IEC 60870 standard)
Example for a 62.5/125 µm fiber
Lmax = (9.4 - 3 - 0.6)/3.2 = 1.8 km (1.12 mi)
