SFP DAC cable Lancom Systems LANCOM SFP-DAC25-1m — 1 m, SFP to SFP, full duplex

Direct attach copper (DAC) SFP cable LANCOM SFP-DAC25-1m by Lancom Systems is a fixed 1 m interconnect solution with SFP connectors on both ends, supporting full-duplex data transmission. It is intended for short-reach links between SFP ports in switches, routers or servers where low latency and cost-efficiency are priorities. The cable is designed and tested for compatibility with LANCOM devices to provide reliable, high-speed connections.

Advantages

The SFP-DAC25-1m delivers up to 25 Gbps aggregate link speed while maintaining backward compatibility with 1G and 10G rates, enabling flexible deployment across mixed environments. Its fixed copper construction reduces power consumption and eliminates the need for separate SFP transceivers, simplifying installation and lowering total cost of ownership. The cable supports hot-swapping and operates over a practical temperature range, providing stable performance in typical equipment racks and network cabinets.

Suitable for

• Short-reach uplinks between switches and routers within a rack or adjacent racks
• High-throughput connections between servers and top-of-rack switches
• Cost-sensitive data center or branch office links where low latency is required
• Environments that require hot-swappable SFP connections for maintenance

Key specifications

• Connector type: SFP to SFP, male on both ends
• Cable length: 1 m
• Supported link rates: up to 25 Gbps (compatible with 1G / 10G)
• Transmission mode: full duplex
• Operating temperature range: 0–70 °C
• Design: fixed direct-attach copper cable
• Color and finish: black, steel elements

How to use

Install the LANCOM SFP-DAC25-1m by inserting each SFP connector into the corresponding SFP port on the devices to be linked. Ensure ports are powered down or follow your equipment vendor’s hot-swap guidance if changing while powered; the cable supports hot-swapping on compatible hardware. After connection, verify link status on both devices and configure interface settings (speed/duplex or auto-negotiation) according to network requirements. Use the cable for short, direct connections where a compact, low-latency link is desired.

Recommendations

For optimal performance, use this cable for connections within the same rack or between adjacent racks and avoid exceeding the 1 m length for which it is specified. Confirm compatibility with your LANCOM or third-party equipment and set interface parameters to match the supported link rates. Protect the cable from sharp bends and mechanical stress to maintain signal integrity and prolong service life.
