Works with
- Multi-mode fiber cables terminated in SC/UPC, 1310 nm, up to 2 km
- 10/100BASE-TX copper over Cat. 5 or better, up to 100 m
- TP-Link MC1400 chassis for rack-mounting multiple units

Is it for you?
An Omada-series standalone media converter that bridges 100BASE-FX multi-mode fiber (SC/UPC connectors, up to 2 km) to 10/100BASE-TX copper over one RJ45 port, powered by an external 9 V adapter.
Choose it if these matter
- Simple, cheap way to bridge legacy 100 Mbps multi-mode fiber runs (SC connectors, 1310 nm) onto twisted-pair Ethernet
- Standalone desk unit that also fits TP-Link's MC1400 rack chassis if you later consolidate several converters
- Auto MDI/MDIX on the RJ45 port means either straight or crossover cable works
Skip it if these rule it out
- Fast Ethernet only: 100 Mbps on both fiber and copper, a legacy speed class of no use for gigabit-or-faster links
- Multi-mode fiber with SC connectors only: not compatible with single-mode fiber or LC-based modern SFP setups
- Powered by a separate 9 V/0.6 A wall adapter rather than PoE or a shared bus, one more plug per converter
