Background of Connector Scenario for Worst Case proposal Simulations for the 10GbE Base SR (850nm, 50µm-MM-Fiber). In the Modeling for the specification of the 10GBit/s transmission on the 50µm multimode fiber was used the following statistics for the connector offsets:

Rayleigh Distribution of connector offsets:
Mean value of 3,58µm,
Probability of exceeding 7µm offset is: 5%
This distribution is used for the current worst case model.
p= 0.054 = 6 x10-6 which is extremely low.
Probability of 5%:
1 connector : offset 7 µm
2 connectors: offset 5 µm
3 connectors: offset 4 µm
4 connectors: offset 3,5µm
Overall probability of the
combination of one connector
of each offset:
