Encircled Flux Mode Conditioners

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.
OLS1-DUAL-EF Light Source

OLS1-DUAL-EF Light Source

Dual multimode Encircled Flux (EF) compliant LED light source designed for performing insertion loss measurements on multimode fiber optic links when used with an optical power meter.  

Multimode output port; 850/1300 nm LED output at CW, WaveID, or dual wavelength WaveID
OLS4-EF Dual EF Light Source

OLS4-EF Dual EF Light Source

Quad light source providing LED and LASER light sources designed for performing insertion loss measurements on multimode or single-mode fiber optic links when used with an optical power meter. The LED port is Encircled Flux (EF) compliant.  

Equipped with industry standard 2 khz test tone, the OLS4 from AFL is an ideal tool to pair with an optical fiber identifier (OFI-200D) for use in fiber identification.
