AXM764 is NETGEAR 10GBASE-LR "Lite" SFP+ Transceiver, a new class of SMF 10G transmitter with LC duplex connector. While not a standard yet, 10GBASE-LR LITE has a specified reach of 2 km (1.24 mile) over standard 9/125µm single mode fiber. 10GBASE-LR LITE isn't a replacement for standard 10GBASE-LR optics: it is just relevant alternative for "shorter" reach SMF applications.
