Encircled Flux Mode Conditioners

Technology improvements continue to push the envelope on multi-mode fibre optic networks. Ever increasing bandwidth requires tighter specifications (lower loss connectors, splices, Etc.). Shrinking loss budgets in turn place higher demands on loss test sets for accurate and repeatable measurements.

Encircled Flux (EF) testing requirements attempt to improve loss test set performance by placing defined parameters on optical test signals emitted from multi-mode loss test sources. AFL Mode Controller Jumpers (MCJs) are simple to use while ensuring the output test signal conforms to EF specifications regardless of the multi-mode test source used.
