The 40Gbps QSFP+ transceiver is well suited for Infiniband and 40GBASE-SR4 / 40GBASE-LR4 applications. It combines the higher density attractions of parallel modules with some of the key advantages normally associated with SFP+ based modules. It is intended for use short reach applications in switches, routers and data center equipment where it provides higher density and lower cost when compared with standard SFP+ modules.

QSFP+ LX4 It is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The optical interface uses an 8 or 12 fiber MTP (MPO) connector.

QSFP+ SR4 It is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The optical interface uses an 8 or 12 fiber MTP (MPO) connector.

QSFP+ LR4 It is designed to operate over singlemode fiber system using four 10Gbps CWDM channel in 1300 band. Which is based on two LC connectors for optical connectivity and supports 40Gbps data rate links of up to 10km.

QSFP+ ER4 It is designed to operate over singlemode fiber system using four 10Gbps CWDM channel in 1300 band. Which is based on two LC connectors for optical connectivity and supports 40Gbps data rate links of up to 40km.

QSFP+ CSR4 It is designed to operate over singlemode fiber system using four 10Gbps CWDM channel in 1300 band. Which is based on two LC connectors for optical connectivity and supports 40Gbps data rate links of up to 40km.
