I am trying to find out the optimal fiber connectivity between 9300-DX 100/400 Gb switches connectivity.
https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/datasheet-c78-743172.html
The link above shows that 400Gb or 100Gb have two different type of fiber. Also take a look at the screenshot below.
400Gb---The choice between Ribbon SMF or Duplex SMF for 400Gb with G.652 standard depending upon the type of module such as QDD-400G-DR4-S, QDD-400G-FR4-S or QDD-400G-LR8-S
100Gb---The choice between Ribbon SMF or Dual Duplex SMF with G.652 and 50.0 standards depending up the type of module such as QDD-2X100-SR4-S or QDD-2X100-CWDM4-S
I did some research and even with G.652 has multiple variations A,B,C etc.
My Core switch rack is about 300m away from my ToR switch rack. Any suggestion so I can ask my cable contractor to run the right fiber between the racks. Ribbon vs Duplex with the correct G.652 with correct sub-standard such as A,B,C for 400Gb, and Ribbon vs Dual Duplex for 100Gb connectivity. I reached out to Cisco Data Center SE, but he was not able to provide the information.
Any help will be appreciated.
