AddOn's QSFP+ direct attach copper twinax cable modules are ideal for very short distances while offering a cost effective and high speed alternative to fiber optics in short reach 40Gb Ethernet and InfiniBand applications. AddOn's QSFP+ to QSFP+ cables provide a 40 Gigabit link across and within adjacent racks and switches. AddOn's transceivers (GBIC, SFP, XFP and XENPAK) are 100% compliant for all of our networking product lines. AddOn transceivers are factory loaded with OEM specific configuration data required for networking compliance. These transceivers initialize and perform identically to the OEM transceivers and can be mixed and deployed with other OEM or 3rd party transceivers, for seamless network performance.
