AdderSFP-CATX-RJ45is an Active Gigabit Ethernet CATx SFP Transceiver for use with theAdderLink INFINITY Series. TheSFP-CATX-RJ45extends up to, but is not limited to, a 100 metre cable length. If you need to extend further, simply add a 1GbE network device to achieve an additional 100 metres.ADDERLink Infinity ALIF 1002andall ALIF Dual variantsprovide a choice of link connections. Each supports Copper-Based Gigabit Ethernet (1000Base-T) as well as Fibre Channel over Ethernet (FCoE). ALIF (1002) and ALIF Dual units provide a single system port (CATx) as standard on the right side of the front panel. An additional SFP cage port, located just to the left, allows simple plug-in transceivers suitable for your application; Optional Fibre SFP Modules provide a 4.25Gbps rate selectable with LC type connectors suitable for up to 500 Metres (Multi-Mode) or 10KM (Single-Mode), while the Gigabyte Ethernet CATx SFP Module extends up to, but is not limited to, a 100 Metre cable length. ALIF Dual units additionally allow for the dual network interface ports to be used in parallel ('Teaming Operation') to produce up to 2-Gigabits per second Ethernet connection speeds with the added benefit of link redundancy that can maintain operation in the event of a failed connection. Teaming offers immediate speed improvements in a one-to-one arrangement as well as in multicast installations.Options:SFP-SM-LC:Single-Mode Fibre SFP TransceiverSFP-MM-LC:Multi-Mode Fibre SFP Transceiver andSFP-CATX-RJ45:Gigabit Ethernet CATx 1000Base-T Copper SFP Transceiver For supply of an RJ45 Copper Port into the Hardware units available SFP Slot
