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.
100G QSFP28
Supporting speeds up to 100 Gb/s, Siemon’s QSFP28 cables exceed 100G Ethernet specifications (100G-BASE-CR4). These cables are designed for high-density applications, offering a cost-effective, low-power option for high-speed data center interconnects.
- Shares the same mating interface with QSFP+ (SFF-8436) form factors, making it backward compatible with existing QSFP+ ports
- Available in half meter lengths
100G Breakouts
Siemon’s QSFP28 to 4 SFP28 Passive Copper Cable assemblies exceed 25G Ethernet specifications (100GBASE-CR4). It shares the same mating interface with QSFP+ (SFF-8436) and SFP+ (SFF-8431) form factors, making it backward compatible with existing QSFP+ and SFP+ equipment ports.
- Features ultra low crosstalk for enhanced performance
- Available in standard lengths up to 5 meters (16.4 ft.) for support of up to 100 Gig (4x25 Gig) Ethernet applications
25G SFP28
These cables support the next generation of applications (25GBASE-CR), connecting switches to network equipment in short-reach applications.
- Available in standard lengths up to 5 meters (16.4 ft.) for support of up to 25G Ethernet
- Features ultra-low crosstalk for enhanced performance
40G QSFP+
QSFP+ copper cable assemblies were developed for high-density applications, offering a cost-effective, low-power option for high-speed data center interconnects. Available in multiple colors, lengths and gauges, the QSFP+ form factor (Quad SFP+) can replace
up to four standard SFP+ connections, providing greater density and reduced system cost.
- Supports emerging 40 Gb/s applications and is available in standard lengths up to 5 meters with longer custom lengths available
- Fully-shielded assemblies combine twin-axial shielded cable configuration with robust die-cast housings for enhanced support of high-frequency data rates
- Over molding on the PCB level provide additional strain relief
40G Breakouts
Siemon hybrid cables allow users to connect SFP+ and QSFP+ equipment. They offer a cost-effective, low-power option for high-speed data center interconnects. The direct-attach assemblies support 4 lanes of 10 Gb/s and are available in standard lengths
up to 5 meters with longer custom lengths available.
- For Ethernet applications from 4 x 10G
10G SFP+ Active and Passive
Siemon’s SFP+ active and passive copper cable assemblies were developed specifically as a cost-effective alternative to optical modules for short-reach links in high-speed interconnect applications such as high-performance computing (HPC), enterprise networking and network storage markets.
- Support data transfer rates up to 10+ Gb/s per lane, meeting or exceeding current standards specifications
- Active cables use signal processing within the connector backshells to extend the length that copper cables can reach beyond the limits of passive copper solutions
- Fully-shielded assemblies combine twin-axial shielded cable configuration with robust die-cast housings for enhanced support of high-frequency data rates
Cisco Compatible 10G SFP+ Active and Passive
Proven by the University of New Hampshire's Interoperability Lab (UNH IOL) for 10G interoperability, Siemon Cisco Compatible SFP+ active and passive copper cable assemblies are programmed specifically to work with Cisco equipment, delivering superior
cost savings and peace of mind for your switch-to-server connections.
- These assemblies will not trigger warning messages or violate Cisco’s warranty when used with Cisco equipment
- Siemon’s SFP+ fully-shielded assemblies combine twin-axial shielded cable configuration with robust die-cast housings for enhanced support of high-frequency data rates
