QSFP+ (Quad Small Form-Factor Pluggable Plus) transceivers are an evolution of QSFP to support 4x 10G channels carrying 10G ethernet, 10GFC fibre channel, or QDR InfiniBand. Switches and routers that implement QSFP+ normally allow for the use of 1 QSFP+ as 4 independent 10G ethernet connections, which greatly increasing port density and reduces costs. There are also fanout cables to adapted a single QSFP28 port to four independent 25G ethernet SFP28 ports, or QSFP28 to 4×SFP28.
