Modal Noise Penalties for Data Communication Links Employing Large Area VCSELs

Cunningham, David G.; Nowell, M.C.; Dowd,P.; Raddatz, L.; White, I.H.



Abstract: 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 experiment. The predicted power penalty at 10 [to the power of minus 9] BER for a VCSEL link, employing 62.5/125 fibre, with six connectors, each with 1 dB MSL, is 0.75 dB.
