Hi Morp
If it is a Cisco Catalyst you could be lucky. Some - not all - of the Catalyst accepts uncoded modules
Good luck

Just a thought I had the Cisco switch is managed then you might be able to adjust the SFP settings to get the cable to work . I found not connect to my Cisco and so never even got optical to work but if you can get in there is always that chance.

I'd have to research how to complete such a feat of magic, but where there's a will there's a way. Hopefully it'll just work though! Cheers Morph |

So I've just noticed mention that the Amphenol DAC cable does not get on with Cisco switches. This may well throw a very large spanner in the works here! My Cisco Meraki was modified thus audiophool.nl/cisco-meraki-switch-ocxo-clock-upgrade/. Can anyone with better tech knowledge let me know if I'm on a loser here? The Amphenol seems to be due tomorrow so I'll find out soon enough I suppose. Thanks Morph I’m using 2 Cisco 2960 switches. It seems only cables specifically for 1G work. I’ve a couple more yet to try to confirm this. |

On a more positive note though I came back from walking my dog to find that an Amphenol 571540012 2M SFP+ 10GbE Direct Attach Passive Copper TwinAxial Cable had arrived. I picked this up cheaply on ebay before ordering the contentious one. I'm pleased to say that it works fine. Unless I'm deceiving myself it definitely outperforms the gnodal DAC cable straight from the off. I've got to go out again shortly but will do a more detailed comparison later today. Cheers Morph |

Appreciate your efforts Matt.
hopefully both of the cables you are waiting on works and there's a clear winner.

Cheers Morph This is good news, so the Amphenol works with your Meraki that has 1G ports? Do you have a link to where you purchased the cable? |

Hi mattsplHere you go www.ebay.co.uk/itm/363796050882. Have just checked the Meraki MS 220 data sheet and it does indeed have 1g ports so it seems I'll be good to go after all. That said I'm really pleased with the Amphenol 571540012. Will be interesting to hear what's what. Cheers Morph |

Cheers Morph Hi Morph, So is your Amphenol cable that arrived today a different one that isn’t skewclear cable? Cheers Matt |

Hi mattspl There's no mention of Skewclear for this cable. I'm guessing but I think it may be an older cable of theirs. It's still excellent though. Cheers Morph |

Well I'm pleased to say that the Amphenol Skewclear DAC cable has arrived and has been accepted by the modified Cisco Meraki MS220 switch. First impressions are positive, however I'm not thinking it is currently superior to the previously mentioned Amphenol 571540012. Given that the Skewclear is a new cable it may need some time to settle in properly. I'll get down to some cable swapping over the weekend. Whilst knowing that my system can't fully benefit from these DAC cables due to lacking a streamer with SFP cage I'm still really happy with their inclusion to the networking side of things. Definite improvement here so will be staying in place. Once again, thank you to MartinT for drawing my attention to this option. Cheers Morph |

I have an update too. Having ordered an Amphenol SF-SFPP2EPASS-003 from Mouser when it showed as in stock, they told be afterwards it was on backorder…anyway it seems some arrived or they had, it arrived from the US today. I’ve inserted it in-between my two FMCs. With no burn in it’s sounds similar to but better than my gnodal. It’s similar in that the tonal balance is as the gnodal. It’s better in that the sound is on steroids, bigger and more dynamic. Tracks seem to pass more quickly too. All in all it’s a great start so I thank MartinT as well (again!). It’s a little incredible but the two most important cables in my system are the: 1) clock to DAC cable 2) the Direct Attached Copper SFP+ cable These are more critical than my analogue cables. |

1) clock to DAC cable 2) the Direct Attached Copper SFP+ cable You know, I think I'm going to agree with that, although I will add power cables into the table: 1) two clock cables to EtherREGEN and DAC (Tubulus Concentus) 2) Direct Attached Copper EtherREGEN to Rendu (Amphenol SFP+) 3) power cables to digital source equipment (Coherent 6D) |

Could anybody with the Amphenol skewclear cable confirm what’s printed on you cable insulation please?
Mine arrived today, but doesn’t seem to work with the Cisco’s.
I’m considering sacrificing a known working DAC cable to solder the sfp’s onto the Amphenol cable, but want to confirm the skewclear first.

mattspl have you got a connection cable for your Cisco Switch ? I think I have a USB one spare and you are welcome to it if you want to see if changing the SFP settings in the switch will make it work . I never managed this and it is one of the reasons I opted for D-Link unmanaged switches which make things really simple as they do all the setting for uou and DAC cables just become plug and play . In your case you may well be better qualified to solder the new cable . Another thought is to buy a couple of SFP 1G Cisco plugs and use them on the skewclear cable this means you will then have your original cable still working just in case the switch does not work . I have a couple of generic DAC cables which are 1 mtr long and you are welcome to one of those to take off the plugs you can try one first just to see that it works and saves you destroying a good cable that you already have . Let me know .
