Encircled Flux
EF is the percentage of power within a given fiber core radius when
light is launched by a transmitter into a multimode fibre.

LOSS
10BASE-F 1514 - 2000 metres 6.8 - 12.5 dB
100BASE-F 2000 metres 11.0 dB
1000BASE-S 275 - 500 metres 2.6 - 3.6 dB
10GBASE-S 32 - 500 metres 1.6 - 2.6 dB
40/100GBASE-S 100 - 150 metres 1.5 - 1.9 dB
• reduction in maximum CIL
• reduction in typical channel length
• increased risk of litigation
• need for accuracy
• need for repeatability
As data rates increase using multimode optical
fibre
Insertion loss measurements need to be more
accurate and comparable now.
Arden Presentation April 2013 14
Why does it matter?
• Insertion Loss in multimode fiber is a
function of Modal Launch Conditions
• Insertion Loss measurements taken
with “underfilled” launch conditions can
lead to optimistic results.
