Encircled Flux Extender Cords

If the output end face of an EF mode controller cable becomes damaged, it is no longer compliant with EF requirements. Due to the fragile nature of these end faces and the cost of EF Mode Controllers, it is important to protect the output end face from damage.

Encircled Flux extender cords are low-loss reference-grade patch cables that provide two economical advantages:

• EF extender cords act as sacrificial cords that protect the fragile output end face of the more expensive mode controller cable from damage - i.e. replacing extender cords costs less than replacing EF mode controllers
• Adapt the EF Mode Controller output to different connector types - i.e. one mode controller and several extender cords are less expensive than multiple mode controllers
