Direct Attach Copper Cable SFP-DAC100-1m by Lancom Systems — 1 m, SFP to SFP, full duplex

Lancom Systems SFP-DAC100-1m is a 1 m direct attach copper (DAC) cable with SFP connectors on both ends and full duplex capability, intended for short-distance interconnects between SFP ports in switches, routers or servers. The cable provides a low-latency, cost-effective link for high-speed networking and cross-connect applications in data centers and wiring closets. It is designed for straightforward, hot-swappable installation and compatibility with LANCOM devices for reliable short-reach links.

Advantages

The direct attach copper construction delivers low latency and low power consumption compared with optical transceivers over short distances, while offering a lower total cost of ownership. With full duplex operation and a robust SFP-to-SFP connection, the cable supports high throughput and stable bidirectional traffic. Tested for compatibility with LANCOM equipment, the cable is supplied in a compact 1 m length that reduces excess cabling in rack environments and simplifies cross-connections.

Suitable for

• Short-reach connections between SFP ports in switches and routers
• Interconnects between servers and top-of-rack switches in data centres
• Patch and cross-connect links in wiring closets and equipment racks
• Low-latency links for high-performance computing and storage networking

Key specifications

• Cable type: Direct attach copper (DAC)
• Connector type: SFP (male) to SFP (male)
• Cable length: 1 m
• Data rate: 100 Gbit/s
• Operation: Full duplex
• Operating temperature range: 0 to 70 °C
• Colour and material: black outer sheath, steel-reinforced connectors
• Hot-swappable: supports insertion and removal during system operation

How to use

Ensure both devices support SFP direct attach copper modules and operate within the specified temperature range. Power down equipment only if the vendor recommends; otherwise, insert the SFP-DAC100-1m directly into the SFP ports on each device until the connectors latch. Confirm link activity via device LEDs or management interface and verify negotiated speed and duplex settings. For removal, disengage the latch mechanism and withdraw the cable straight out to avoid damaging ports.

Recommendations

Route the 1 m cable to avoid sharp bends and mechanical stress; maintain bend radii recommended by the equipment vendor. Use the 1 m length for short rack- or shelf-level connections to reduce excess cabling. For environments with higher ambient temperatures, ensure adequate ventilation and monitor link stability after installation.
