Review on High-Speed 10GBase-T SFP+ Transceiver with RJ45 Copper Module - Compatible with Cisco SFP-10G-T-S, Ubiquiti, D-Link, Supermicro, Netgear, Mikrotik - Supports up to 30m Distance by Mike Rubenstein

These transceivers are DAC encoded, not 10GBASE-T or 10GBASE-SR like some other transceivers. This means that if your switch is really picky about the DAC (like my Aruba S2500/S3500) it will recognize the transceivers but not call. /1-------Vendor Name: 6COMVendor Serial Number: <Removed from view>Vendor Part Number: 6C-SFP-10G-TAruba Certified: NOCable Type: Unknown Connector Type: Copper Pigtail Wavelength: 256 nm Cable Length: 1 m If you have an Aruba S2500/S3500, Ipolex 10G-SFP-T Ubiquiti works well as a 10GBASE-T SFP+ transceiver.
