40G QSFP+ fiber module

40G QSFP+ (Quad Small Form factor – Pluggable) : four-channel SFP interfaces (QSFP), QSFP is in order to meet the market for higher density of high-speed Pluggable  for the demand of the solution.
This 4 channel pluggable interface transmission rate reached 40 GBPS. Many XFP mature key technologies are applied to the design.

40G QSFP+ fiber can serve as a kind of solution and velocity and density were better than 4 channel CX4 interface. Because in XFP 10 GBPS per channel under the same port volume of support four channel data transmission speed, so the density of QSFP can achieve XFP product 4 times, SFP + 3 times of the product. With 4 channel and a higher density than CX4 QSFP interface has been adopted by the InfiniBand standard.
