  What is 40G QSFP+?

QSFP+ stands for Quad Small Form-Factor Pluggable Plus. A parallel and hot-swappable fiber optical module that provides high-density 40G connectivity options for high-performance computing networks and modern data centers. It has four independent receive and transmit optical channels that can terminate to another 40G QSFP+ transceiver, or can be distributed to four separate 10 Gigabit SFP+ transceivers. The QSFP+ modules , in brief, connect the entire electrical circuitry of your system to an optical external network.

• What is 40G QSFP+ CSR4?

40G QSFP+ CSR4 optical transceiver is a four-channel small pluggable optical module. Its transmission rate can reach 40Gbps and the maximum transmission distance is 300m. It has 12-Fiber MTP/MPO interfaces and usually connects with MTP/MPO multimode fiber patch cables with a wavelength of about 850 nm. The QSFP-CSR4-40G optical module uses VCSEL lasers, which are ideal for applications such as parallel optical transmission and parallel optical interconnects, and are highly cost-effective. The module operates from a single +3.3V power supply a nd LVCMOS/LVTTL global control signals such as Module Present, Reset, Interrupt and Low Power Mode are available with the modules.
