F-tone 40GBASE-LR4 QSFP Module supports link lengths of up to 10km over a standard pair of G.652 single-mode fiber with duplex LC connectors. The 40Gbps QSFP+ transceiver is well suited for Infiniband and 40GBASE-LR4 applications. It combines the higher density attractions of parallel modules with some of the key advantages normally associated with SFP+ based modules.
