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 . Thanks for the kind offer Bencat. I’ve tried about 6 DAC cables now. 3 of which work no problem. I did go into all the settings to try and get 2 previous cables working, but the switch still can’t see those cables. I’ll try later with the Amphenol cable. FS, MikroTik and Genuine Cisco DAC cables work no problem. |

Amphenol SFP+ SkewClear Thanks Martin. No mention of Belden on my cable. I’ll check again when I get home. |

Haven't seen any mention of directionality....
Could the cable be better one way ?

The matching (sealed) bag. The label on mine was the same except 1 meter vs 3 meters and the two numbers 15/15 on yours are 33/20 on my packet. The cable didn’t work with the Cisco, so I cut it open and it was triple screened. Whether or not that proves it’s belden I don’t know. I then used the FS cable in the hope of transferring the sfp ends onto the Amphenol cable, but the solder terminations are hot glued down and I damaged the trace on the board removing the cables. |

Eek! Could you buy fresh SFP connectors and try again?
Also - is your cable marked Belden or is it too short to catch the name?
Methinks Belden manufacture the SkewClear cable specially for Amphenol.

Haven't seen any mention of directionality.... I always use my cables in the direction left-right is source-destination. That way I always re-use them the right way round, the way they've been burned-in and used. |

I’ll post a picture later on. You can see all the writing, but no mention of Belden, just numbers really. |

It seems that the word "Belden" is also missing on the cable that AfterDark is selling:  The numbers are also not the same. Torben |

I’ve also seen pictures of Amphenol written on the cable before the numbers.

My cable doesn’t have Belden printed on it. It has a similar set of number though they aren’t quite the same as the Belden ones. The number on mine is the same as the AfterDark - E320576 It was assembled in Mexico. I’d be a little surprised if the cable isn’t manufactured by Belden as they make most cable.   |

That’s the same number that was on my Amphenol cable. Cables may be assembled at more than one location so that can account for some differences. Also, there may be differences in part numbers as extremely similar cables will likely be available with differing environmental specifications. |

No mention of Belden on my latest cable either. Same details as shown in Clive's picture above but assembled in China with a date of 20/6/12. Interestingly the previous Amphenol cable, Amphenol 571540012 2M SFP+ 10GbE Direct Attach Passive Copper TwinAxial which I was impressed with prior to the arrival of the one being discussed just now..... has exactly the same details as the one in Clive's picture. Hmmmmm. ps. Sorry to hear of your travails mattspl. |

My Mexico assembled cable has 17/06/03 printed on it. This could be a date of the batch of cable, if it is I suspect it’s 2017 when the wire was drawn and sheathed. Quite possible the date being 3rd June 2017 (American dates….).
It could be that cablesondemand are US based whereas Amphenol have low cost volume assembly plant elsewhere.
When I worked with the Auto industry on MRP II, JiT and supply chain systems I visited the US often. Wiring harnesses and individual cables were assembled by Tier 2 suppliers in Mexico and shipped to Dearborn, Detroit, Moline etc, they would fill an 18-wheeler to send them from Mexico. Other items such as exhaust systems were extruded in the US then sent on 18-wheelers to Mexico for welding and returned to the US.

Other items such as exhaust systems were extruded in the US then sent on 18-wheelers to Mexico for welding and returned to the US. Ah, yes of course, American dates.  Thanks for the correction! The latest cable came from Digikey in the US and the 2m Amphenol 571540012 was bought from a UK based ebay seller. Either way I'm not too concerned about this anomaly as I'm really pleased with how these cables sound. If and when I get the funds together to purchase the Signature Rendu Deluxe I'll run the 2m DAC cable to it from the Meraki switch. |

Have you testet it with Meraki switch? Does it work? Torben |
