Allied Telesis 10 km SFP+ Module - 1 x LC 10GBase-LR Network10

Customers moving to Gigabit (1000Mbps) may find that existing multi-mode fiber may not be suitable for their network, as the distance required is over 220 m. Allied Telesis recommends using the AT-SPEX optical transceiver, which uses non-standard optics, but supports the 2 km distance.
