The T020-001-LC10G FC to LC 10 Gb Adapter converts a native FC fiber female port on the Tripp Lite T020-001-PSF Multi-Function Optical Fiber Cable Tester to an LC female port for 50/125 OM3 multimode cable testing. "OM3" is clearly labeled on the unit to differentiate the T020-001-LC10G from other adapters. Included dust caps keep the connectors clean when not in use.
