FOCONEC manufactures keystone jacks or inserts, which are suitable for SC, LC, or ST adapters, and provides a fiber connectivity & cabling solution for an existing voice, data, and video transmission system.
Our keystone jack plugs are with a standard mounting footprint and could be installed on the surface wall outlet box, faceplate, and patch panels.
FOCONEC offers a one-stop-shop solution. We have blank keystone patch panels to go with fiber optic keystone jack plugs. They could be 12, 24, or 48 port patch panels with 1U/2U rack space, allowing a combination of Ethernet, fiber, and telco connections in one central location.
Our Fiber keystone jack inserts are made to operate under rough conditions (-20°C to +70°C), delivering long-time steady network performance. All adapters assembled are with ceramic mating sleeves, so as to realize low insertion feedthrough connector to connector coupling. Steel clips on LC/SC adapters are made of stainless steel for sturdy connections.
