OSFP-FT (Finned Top), OSFP-RHS (Riding Heat Sink), QSFP56, QSFP28, QSFP+, SFP-DD, SFP56, SFP28, and SFP+ form factors up to 400G.  Typical applications include data center requiring reliable, low latency, high-quality cabling options. Our cables are competitively priced, available in various lengths, including many 1/2 meter increments and color options, and are all backed by Siemon’s superior technical service and support. Siemon high-speed cable assemblies are MSA (Multi-Source Agreement) compliant to ensure compatibility across equipment from various vendors.

Direct Attach Cables [DACs]

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 (plus orange and silver in MESH sleeve), in half meter lengths from 0.5M to 3M and full meter lengths up to 5M depending on speed. Great for high-density systems where power consumption and heat generation are concerning factors

Active Optical Cables [AOCs]

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.
