Copper and Fiber High Speed Interconnects

Connecting The World To A Higher Standard™

Direct Attach Cables

The Siemon Company’s Direct Attach Copper Cables (DACs) are offered in SFP and QSFP configurations in data rates of 10G, 25G, 40G and 100G. Our assemblies are available in ½ meter lengths and several jacket color options, with pricing that is often less than half of fiber solutions. These twinax cable assemblies are especially beneficial in data centers utilizing top of rack and some middle or end of row architectures directly connecting switches to servers. Independently tested for interoperability with many major switch and server brands, our DACs are compliant with industry standards, ensuring high-performance, high-quality options for today's direct attach equipment connections.

25G and 100G DACs

Siemon’s interconnect assemblies are designed for high-density, point-to-point applications in data center, edge computing or AV applications. These DACs support speeds of up to 100G, exceed 25GBASE-CR and 100G-BASE-CR4 specifications and feature ultra-low crosstalk for enhanced performance.

10G and 40G DACs

The 40G and 10G versions were developed specifically as a cost-effective alternative to optical models for short reach links in high-speed interconnect applications. The fully shielded assemblies combine twin-axial shielded cable configurations with robust die cast housings for enhanced support of high frequency data rates.

Active Optical Cables

Active Optical Cables (AOC), are fixed fiber assemblies of two optical engines and a fiber patch cord, which are available in stock lengths of up to 100 meters. A more cost-effective alternative to transceivers, AOCs offer an extended reach option that offer the flexibility of traditional optical modules and are available in 10G, 25G, 40G and 100G configurations.

25G and 100G AOCs

Our 100G and 25G AOCs are capable of transmitting data up to 25G & 100G and offer an easy installation with a flexible, multimode fiber cable. They are a high-performance and low power consuming cable that are Ethernet, Infiniband and MSA compliant.

10G and 40G AOCs

Siemon’s 40G and 10G eliminate interoperability issues of transceiver assemblies and are equipped with Digital Diagnostic Monitoring and are a thinner diameter which promotes better airflow. These cables also include a high-strength pull tab latching system with promotes more secure installations.
