The certification has been given to the fibre optic 4-Channel Brass Hermaphroditic Plug and fibre optic 4-Channel Brass Packing Gland Receptacle, also known as the GoldRush connectors.

“By responding to specific customer needs and leveraging the family of AFSI TFOCA-II connectors, the GoldRush series of fibre optic connectors was born,” the company said. “These innovative interconnect solutions have become an enabling technology for digital mining. AFSI’s GoldRush connectors address specific mining requirements for the future of intelligent mining.”

The design enables GoldRush connectors to seal against high humidity and moisture conditions while allowing full axial and orbital movement of the mated ferrule, providing the lowest possible insertion loss and back reflection of any mining style connector, the company said.

The GoldRush connectors are the only MSHA-certified fibre optic connectors for use in underground mines under Title 30 CFR, Part 18.

AFSI is a leader in the design, development, and manufacturing of fibre optic products for harsh environments. AFSI has developed and patented fibre optic interconnect components and systems such as termini, M28876, MIL-ST, TFOCA and the TFOCA-II connector.
