Direct Attach Cable SFP-DAC40-1m by Lancom Systems — 1 m SFP to SFP, full duplex, steel/black

Lancom Systems SFP-DAC40-1m is a 1 m direct attach cable with SFP connectors on both ends, designed for short-distance high-speed interconnects between SFP-equipped switches, routers or transceivers. The steel and black connector housing provides a durable shell suitable for rack-to-rack links, top-of-rack connections and other equipment interlinks. This direct attach cable supports full duplex operation and is intended as a tested, compatible alternative to separate SFP transceivers for LANCOM devices.

Advantages

The SFP-DAC40-1m offers a compact, low-latency interconnect solution that reduces the need for separate transceiver modules and fiber cabling. Its tested compatibility with LANCOM products ensures reliable connectivity and simplified installation. The steel/black connector housing enhances mechanical durability while the 1 m length is optimized for short link distances commonly found in rack environments.

Suitable for

• Rack-to-rack links in data centers and server rooms
• Top-of-rack (ToR) connections between switches and access equipment
• Direct equipment interlinks between SFP-enabled routers, switches and transceivers

Key specifications

• Cable length: 1 m
• Connector type: SFP to SFP (male)
• Operation mode: full duplex
• Housing: steel, black
• Intended use: short-distance high-speed interconnects

How to use

Insert each SFP connector into the SFP port of the devices to be connected while the devices are powered according to your equipment manufacturer’s guidance. The cable is swappable during system operation; follow the host device hot-swap and safety procedures. Verify link status and speed on the connected devices after insertion to confirm proper operation.

Recommendations

Use the 1 m SFP-DAC40-1m for short, direct links inside racks or between adjacent racks. Avoid physical strain on the cable and ensure connectors are seated firmly. For distances beyond short rack-level links, consider optical transceivers and fibre cabling appropriate for your topology and distance requirements.
