TechLogix media converters adapt fiber signals to a variety of different formats and/or cable types. The TL-MC-1S2R features one SFP port (SFP module sold separately) and two RJ45 twisted pair ports, effectively adapting twisted pair-based devices to fiber for longer transmission distances. The MC-1S2R supports multimode fiber when paired with a multimode SFP module and single mode fiber when paired with a single mode SFP module. Two TL-MC-1S2R media converters are required for most applications - one for each end of the cable run.
