10BaseFL, also called as 10Base-FL, is a 10-Mbps baseband Ethernet specification using fiber-optic cabling. 10BaseFL is part of the 10BaseF specification and, while able to interoperate with FOIRL, is designed to replace the FOIRL specification. 10BaseFL segments can be up to 1,000 meters long if used with FOIRL, and up to 2,000 meters if 10BaseFL is used exclusively.
