Cabling QSFP to SFP options - Cisco Nexus

[aok]

We’re connecting uplinks from a new pair of N9K-C93108TC-EX rack switches to our core, however the new switches only have QSPF ports for fiber and the core side has limited 10G ports and no spare 40G ports. What are our options for cabling? We have some qsfp-4SFP10G-cu3m breakout cables but it doesn't seem optimal to plug in the 40G side to the rack switch and only use one of the four 10G cables on the core side. Any suggestions on alternatives?

Thanks

Hi,

If you are limited on space on core switch and you just want single SFP+ connection so you can look for adapter like this: https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/data_sheet_c78-729336.html
If not just connect 4 all sfp+ ends to your core switch and roll with sweet 40gb connection :D
