QSFP Question

I have used SFP and SFP+ for a long time but I have not used QSFP really. I have a Juniper EX4600 that has 4 QSFP+ ports. I have seen references online that you can use a duplex single mode fiber and run 40gig over two fibers. Is that correct? If so how does that work? Does each fiber transmit on two separate wavelengths like 1270 & 1330?
