Data Center Server
and Storage System Cable Assemblies
This application & product guide will explore the available DAC and AOC options as well as the key considerations and information you need to be aware of to maximize your data center budget.
Direct Attach Cables
A cost-effective, low power option for inter-rack connections, DACs provide superior performance and reliability in high speed top-of-rack applications. Available in black, red, white, or blue jacket colors, in half meter lengths from 0.5M to 3M and full meter lengths up to 10M. Great for high-density systems where power consumption and heat generation are concerning factors.
Active Optical Cables
Multimode fiber AOC cable assemblies are about half the cost of transceivers and are factory terminated, negating any interoperability or installation issues. Siemon AOCs are ideal for longer reach, point to point connections in data centers, cabinets and equipment outside of the rack. Energy efficient design requires less power than transceiver assemblies with smaller bundles promote better airflow and lower cooling costs.
Patch Cords for Transceiver Assemblies
Compatible with transceiver modules, our premium line of XGLO fiber cable assemblies meet stringent performance specifications and support 10, 25, 40, 50, 100, 200 and 400G no matter what the application.
