We have the next equipment 7050QX-32

Total SFP+ Ports 0
Total QSFP+ Ports 32

Max 40GbE Interfaces 32
Max 10GbE Interfaces 96

What optics and cable adapters are required to have all the ports working in 10 Gbps?

I would like to connect the next devices
24 servers working in 10 Gbps using copper
24 servers working in 10 Gbps using fiber
24 remote switches in 10 Gbps link 1 km
24 remote switches in 10 Gbps link 10 km

Hi Ronald, note that the 7050QX-32 is a single chip switch. There is a limitation on the T2 chip that allows for only 104 interfaces. This means that only the 1st 24 ports can be broken out into 10G ports, the last 8 ports can only be used as 40G ports. 24 x 4 = 96, plus the 8 x 40G ports gives you a total of 104 interfaces.

In terms of optics and cables:

- When you say Copper, do you mean DAC cables? If so, this would be the SKU CAB-Q-S-(lengths, 0.5 – 5m)

- For Multimode Fibre breakout from 40G to 10G, you would require the QSFP-40G-SR4 for up to 100m, and QSFP-40G-XSR4 for up to 300m. Along with the optic, you would require a breakout cable like the CAB-M12P4LC-M3, which is OM4 MTP12 to 4 LC.

- For 1km Fibre breakout from 40G to 10G, you would require the QSFP-40G-PLRL4 optic, along with the breakout cable CAB-M12P4LC-S3, which is SM MTP12 to 4 LC.

- For 10km Fibre breakout from 40G to 10G, you would require the QSFP-40G-PLR4 optic, along with the breakout cable CAB-M12P4LC-S3, which is SM MTP12 to 4 LC.
