rf9000 Posted March 10, 2021 Share Posted March 10, 2021 All, My main switch is an Araknis 310. I want to connect two Araknis 210 switches via the SPF uplink ports. Can someone suggest some good cables to use? In the Araknis specs, it doesnt say if they are SPF+? So not sure what to use Quote Link to comment Share on other sites More sharing options...
rf9000 Posted March 10, 2021 Author Share Posted March 10, 2021 Some thing like this? Just that these say SPF+ and I dont know if 10Gtek is a good brand? https://www.amazon.com/10G-SFP-DAC-Cable-SFP-H10GB-CU0-5M/dp/B01M09C9NZ Quote Link to comment Share on other sites More sharing options...

A SFP module can work in a SFP+ port but typically not the reverse. You can try below link... https://www.fs.com/c/1000base-sfp-81 Araknis isn't listed as a Mfg but FS.com are super fast with email and will tell you which ones will work. You have 2 choices for modules, a Ethernet module or a fiber module. No performance difference in your application. Now, having 2 transceivers instead of one cat6 connected into a normal port is more expensive as your speeds are still limited to 1Gbe. So the only reason to do this vs connecting the switches via an ethernet port is to liberate an additional port. No performance benefit over just a standard Cat6 cable.

So those cables wont work? I'm looking for complete cables that will work the best with the Araknis switches Quote Link to comment Share on other sites More sharing options...

I'm looking for complete cables that will work the best with the Araknis switches I would say no. They are SFP+, 10Gbe. Most of the all in one cables seem to be SFP+ vs SFP. Not sure if they make an all in one SFP cable. They don't seem to be readily available on Amazon. Maybe someone else has a link to one...

VIS Posted March 10, 2021 Share Posted March 10, 2021 2 hours ago, rf9000 said: Is it odd that the Araknis ports are not SFP+? To make the determination, you need to understand the device you are using and what interface types are supported. In your case, Araknis 310, only supports 10/100/1000. That represents 10MB, 100MB and 1000MB. See spec sheet, https://www.snapav.com/shop/en/snapav/araknis-networks-310-series-dual-wan-gigabit-vpn-router-an-310-rt-4l2w-a. The LAN/WAN interface from spec sheet shows it supports LAN/WAN - Combo RJ45/SFP 10/100/1000Base-T: x1 USB:x1 (USB 3.0). The 1000MB is 1G. When you see SFP this means it supports up to 1G and can be either fiber or copper SFP. For your environment with CAT5/6 cables, this is considered copper. An SFP+ means it supports 10G. I hope that helps. Quote Link to comment Share on other sites More sharing options...
mindedc1 Posted March 10, 2021 Share Posted March 10, 2021 8 hours ago, rf9000 said: Is it odd that the Araknis ports are not SFP+? Yes, odd and jankey... In their defense, not much actual need for 10G in residential, the fact that it's about the same cost now as 1G is a different conversation. To OP, 1G DAC cables are kinda weird/rare. I would just buy two 1G SX optics from FS.com and a length of OM-3 50 micron with LC connector fiber patch cable. You do not want single mode cable with SX optics, you don't need OM-4. The optics are $7/each and the fiber should be about that. If you know somebody in the IT business they probably have a bucket of the things pulled from customers as nobody uses 1G uplinks anymore. I would not use second hand fiber, not worth it. Parting shot, fiber has a bend radius of like 2". Hard bends, zip ties, rough handling result in problems in the future with fiber.

msgreenf Posted March 10, 2021 Share Posted March 10, 2021 But it's not odd and janky. They can't handle 19gb backplane. Quote Link to comment Share on other sites More sharing options...

Uh yeah. according to the stats the 8 port is a 20G backplane, the 16 and 24 ports are 32r and 56g respectively... They actually list Head of Line Blocking as a feature, that's an indicator of poor performance in fan-in scenarios which is what you're creating with a 1G uplink....I wouldn't brag about that. If the switch supported VOQ that would be something to brag about... For similar price you get a 4xSFP+ uplink in an enterprise switch (and I don't mean ubiquiti, thats not enterprise, similar pricing for the "pro" series though)..... not good value for the money IMHO. 10G ports shouldn't be unusual or expensive in 2021....anything with an SFP port should be 10G. We're moving to 25G for IDF usage thanks to backpressure from APs with Multirate (2.5/5G) uplinks.... time moves on. Quote Link to comment Share on other sites More sharing options...

I have switched around the setup a bit and I'm now using a Araknis 210 48 port POE as my main switch. Then want to uplink a Araknis 310 24 port POE and a Araknis 210 24 port POE. Someone suggested to just use the SFP connectors with a CAT6a cable. What are your thoughts? Quote Link to comment Share on other sites More sharing options...

So I'm guessing in the scenario above I would need four of them? https://www.fs.com/products/36901.html Quote Link to comment Share on other sites More sharing options...

As mentioned earlier, you can get a Ethernet module or fiber. Latter is cheaper. As mentioned earlier, I would email me them to make sure you get one compatible with Araknis. My guess isAraknis accepts a wide array of modules but good to check. Quote Link to comment Share on other sites More sharing options...
ejn1 Posted March 11, 2021 Share Posted March 11, 2021 @rf9000 This is the fiber cable that you would need to connect the modules... at the length you need. It's more bend insensitive also but I still would not bend too much. https://www.fs.com/products/41730.html Quote Link to comment Share on other sites More sharing options...

On the modules, they have boxes to check for compatibility. Araknis is not listed so I would email FS and just ask which version to get for compatibility with Araknis. For example, they may say get the Cisco module etc. Some mfg of switches have wide compatibility and some less so good to check imo. Quote Link to comment Share on other sites More sharing options...

Hey, do you also recommend a cable like this to run from the router to the main switch? Quote Link to comment Share on other sites More sharing options...
