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.


Why does it matter?

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.


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.

Modal Explorer Launch Condition Analyser


• Measures Encircled Flux – which is the industry’s chosen metric for Modal Launch Condition / Modal Filling in multimode fibers.

• Real time measurement

• 850 and 1300nm

• Standards compliant

ModCon

Mode controller


ModCon

Mode controller

• Produces standards compliant launch condition from any light source

• 50/125 µm or 62.5/125 µm

• Works at 850 and 1300nm

• Conforms to IEC 61280-4-1 / OFSTP-14

• Reference grade connector on output


Conclusions

1. Measurement and Control of Modal Launch Conditions – Arden’s specialization

2. All hardware and software design, build and support taken care of “in-house”.

3. You will be supported by engineers who use equipment daily

4. You can have solutions tailored to your requirements
