For the first time, high mode selective loss (MSL) margins for large area VCSELs are theoretically justified. Calculated speckle visibility and power penalties agree with experiments. The predicted power penalty at 10-9 BER for a VCSEL link, employing 62.5/125 fibre, with six connectors, each with ldB MSL, is 0.75dB.
