100/400Gb Fiber Standards

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.

300 meter would need to think about structured cabling. 

 

100G/400G makes cabling more complex - 1) fiber types: single mode vs multi-mode; 2) connectors: LC, MPO12, MPO24, and the newest one MPO16. There is a copper DAC cable (CU version) which can only reach 5 meter range - so that's out of the question here.

 

Depending on how many connection you need to run: suggesting you implement 24F or 48F trunk cables, maybe multiple of them. Both sides should terminate in a panel / cassette, so the user would just run a 3 meter patch cable off of the panel. 

 

Let me know if you want to do a 1-1 session.
