The TRENDnet TFC-10GSFP is a standalone media converter that connects 10GBASE-T (10 Gigabit Ethernet via RJ-45) with SFP+ optical modules. It provides one RJ-45 port at 10 Gbps and an SFP+ slot for optical transceivers, enabling network expansion and interoperability between copper and optical links. It is ideal for data centers, network cabinets, and environments requiring the conversion of 10G copper to optical SFP+ links and for connecting devices beyond copper distance limits.
