Types of 10 Gb cables for trunk

I have two 10 Gb Netgear switches on two sides of the server room, about 20 feet of each other. Right now, the trunk is only 1 Gb because I'm using a Cat 5 cable. I would like to make the trunk 20 Gb. What would be the best way to do this? So far these are the two options.

 

1. Use two Cat 6 cables (since Cat 6 can do 10 Gb)
2. Use two 10 Gb SFP+ cables.

 

I prefer option 2 because if I use option 1, I need to re-assign my ports (just a minor thing).  

 

The two switches are the same model, S3300-52X-PoE+ ProSAFE 48-Port Gigabit

 

Any suggestions?

  • Links participating in a LAG should run on similar speed and latency. It's the LAG operating the trunk - so be careful that you set the VLAN config on the LAG, not the individual link.

    Start with the S3300-28X, S3300-28X-PoE+, S3300-52X and S3300-52X-PoE+ Data Sheet 

     

    AXM761-10000S SFP+ Transceiver 10GBASE-SR (Short range, multimode)
    AXM762-10000S SFP+ Transceiver 10GBASE-SR (Long range, single mode)
    AXM763-10000S SFP+ Transceiver 10GBASE-LRM (Long range, multimode)
    AXM764-10000S SFP+ Transceiver 10GBASE-LR Lite (Long range lite, single mode)
    AXM765-10000S SFP+ Transceiver 10GBASE-T Copper RJ45 GBIC - up to 30 meters only
    AGM731F-10000S SFP Transceiver 1000BASE-SX (Short range, multimode). Note: Stacking requires 10G SFP+ modules.
    AGM732F-10000S SFP Transceiver 1000BASE-LX (Long range, single mode). Note: Stacking requires 10G SFP+ modules.
    AGM734-10000S SFP Transceiver 1000BASE-T (Short range, RJ45 copper). Note: Stacking requires 10G SFP+ modules.
    AXC761-10000S SFP+ DAC CABLE (1m)
    AXC763-10000S SFP+ DAC CABLE (3m)

     

    For example two (resp. four) AXM761 or compatible 10GBase-SR and one pair (resp. two pair) multimode fiber assembled with a pair of LC/UPC connectors will do the job.

     

    Any other pair of SFP+ fiber transcivers with the matching fiber (essential!) will do the job, too. SR or LRM might be overkill in cos ans power.

     

    AXM765 or comatible will allow using ~30 meters of CAT6 or better copper connection - more expensive modules, but easy self-install e.g. on a patch panel if required, and free up on-board 10G copper ports for othr usage.

     

    Or one (resp. two) SFP+ active DAC 10 meters or 32 ft cable (Netgear does provide max 3 meters) - permitting this is sufficient - will do the same job hopefully.

      Sounds like I need to use SFP+ since I’m trying to make the connection faster between the switches and NAS

        I’m assuming I need to setup the LAG on the two SFP+ ports to make it 20 Gb? Also what happens if I leave the 1 Gb trunk connected? Would I have 21 Gb?
