Connecting QSFP 40G SR4(MPO/MTP) to QSFP-40G-SR-BD (LC)

[zentron]

We have a case where we've QSFP 40G with MPO connector(SR4), and we want to connect it to QSFP-40G-SR-BD. I have not found an adapter or converter that can connect between 40G MPO and 40G LC. Is there any solution or advice to solve this case? because partners have already bought QSFP-40G-SR-BD where they should have bought QSFP-40G-SR4 for their network. They might not be able to exchange the QSFP-40G-SR-BD part, because they already bought it. Any solution for this case?

QSFP-40G-SR-BD is a Cisco proprietary optic while QSFP-40G-SR4 is standard optic. So, unfortunately, you can't connect these 2 together unless you have the same type of optics on both sides.
