Which connector is standard in the recent EIA/TIA 568 cabling standard?

The recent EIA/TIA 568 cabling standard emphasizes the use of connectors that comply with the Fiber Optic Connector Intermateability Standard (FOCIS). This standard ensures that various types of fiber optic connectors can interoperate without issues, promoting versatility and compatibility in network installations. By endorsing "any connector with a FOCIS document," the EIA/TIA 568 standard acknowledges a range of connectors that meet specified performance criteria while providing flexibility for installation based on infrastructure requirements and existing technologies.

This choice allows for the inclusion of both common connectors like LC, SC, and ST, as long as they are compliant with FOCIS, thus not limiting to a specific connector type but rather a broader set of options that adhere to performance and interoperability standards in fiber optic cabling.
