Not every network uses a single manufacturer’s products throughout.  Some may use Cisco at the core, Aruba at the edge, Palo Alto firewalls, HP servers, and EMC storage or a combination of many others.  Normally when using a single vendor, these systems can be connected using that manufacturer’s Direct Attach Cables (DAC) or Active Optical Cables (AOC).  But when multiple vendor systems are used together, that is not an option.  Solution?  Use GigaTech Dual Coded DAC and AOC solutions!
