Cabo de ligação direta Lancom Systems LANCOM SFP-DAC25-3m — SFP para SFP, 3 m, duplex integral

The LANCOM SFP-DAC25-3m is a 3 m direct attach copper cable with SFP connectors on both ends designed for short-range interconnections between SFP ports in switches, routers or servers. It supports full-duplex operation and provides a low-latency, cost-effective link for top-of-rack and network equipment interconnects. The cable is intended as an alternative to separate SFP transceivers and has been tested for compatibility with LANCOM devices to ensure reliable operation within supported environments.

Advantages

This direct attach cable delivers up to 25 Gbps link speed while maintaining full-duplex data transfer. Its 3 m length is suited to short-range connections inside racks or between adjacent equipment. The cable can be swapped during system operation, reducing downtime during maintenance or replacement. Designed and tested for LANCOM products, it offers a balanced solution of performance, simplicity and cost-efficiency for network installations.

Suitable for

• Top-of-rack switch to switch connections
• Interconnects between routers and switches within the same rack
• Server to switch connections in data centre racks
• Short-range patching in network cabinets and wiring closets

How to use

Install the LANCOM SFP-DAC25-3m by inserting each SFP connector into the SFP port of the devices to be linked, ensuring correct alignment and a secure latch. The cable supports hot-swapping, so it can be inserted or removed while systems are running if the network configuration and connected equipment support live changes. Verify link status on both devices after connection and configure link speed and duplex settings on your network equipment if automatic negotiation is not used.

Recommendations

Use this cable for short-distance, high-speed links inside racks or between adjacent equipment. Avoid routing the cable near strong electromagnetic sources and ensure it is not sharply bent; observe manufacturer guidelines for minimum bend radius. Confirm compatibility with your LANCOM devices and verify firmware or hardware requirements before deployment.
