Arista compatible QSFP-40G-PLR4, 40G QSFP+ optic, up to 10km over parallel SMF (4X10G LR up to 10km) MTP-12

10Gtek's QSFP-40G-LR4 PSM QSFP+ Module supports link lengths of up to 10km over a standard pair of G.652 single-mode fiber with duplex LC connectors.The 40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device.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.
The module operates with single +3.3V power supply. LVCMOS/LVTTL global control signals, such as Module Present, Reset, Interrupt and Low Power Mode, are available with the modules. A 2-wire serial interface is available to send and receive more complex control signals, and to receive digital diagnostic information. Individual channels can be addressed and unused channels can be shut down for maximum design flexibility.
