Sample calculation
● Optical budget for VN2002: 11dB
● Cable loss: 2.5dB/3280ft / 2.5dB/km
● Male connector loss: 1.0dB
● Transmission losses: 0.5dB
Length = (optical budget – 2xmale connector loss – transmission losses)/(cable loss
per km)
Length in km = (11dB – 2x1dB – 0.5dB)/2.5dB per km = 3.4km
Length in ft = (11dB – 2x1dB – 0.5dB)/2.5dB/3280ft = 9842ft
