The Transition Networks TN-GLC-GE-100FX is an SFP (mini-GBIC) transceiver with an LC 100Base-FX interface, suited to network administrators adding a matching fiber connection to compatible SFP-equipped network hardware.
Recommended For
- Network administrators adding a 100Base-FX multimode fiber link to a Cisco Catalyst 2970, 3560, or 3750 Gigabit SFP slot; Lantronix specifically lists this module for that use.
- IT teams connecting Fast Ethernet switches or routers over multimode fiber, when the link uses duplex LC connectors and is within the module’s 2 km rated distance.
- Network operators building 100Base-FX metro-edge or xDSL application links over multimode fiber, where Fast Ethernet—not Gigabit Ethernet—is sufficient.
- Teams maintaining compatible fiber infrastructure that needs a hot-pluggable, MSA-compliant SFP for 100Base-FX links, including the Lantronix xFMFF4040-100 optical line converter.
