Direct Attach Cables for Data Center Interconnection
Direct attach cable assemblies are ideal choices for short-reach direct connection applications. Generally, they are used in the EDA (Equipment Distribution Area) where cabinets and racks house end equipment (servers) and where horizontal cabling from the HDA (Horizontal Distribution Area) are terminated at patch panels, as shown in the following picture:
Compatible Brands
Widely compatible with Cisco, Huwei, H3C, ZTC and other SFP optical switches, routers, firewalls, network cards, etc.
