Lancom SFP-DAC40-1m (60176), 40Gbps QSFP+ Direct Attach Copper Cable, SFP+ to SFP+ 1m Length

Lancom SFP-DAC40-1M (60176) is a 40Gbit/s QSFP+ Direct Attach Copper (DAC) cable with 1m length, designed for short-range, high-speed connections between LANCOM switches or compatible QSFP+ ports in data centers and enterprise networks.​

Performance Specs

• Delivers full 40Gbps throughput (40GBase-CR4 compliant) over passive twinax copper with low insertion loss and minimal latency, supporting distances up to 1m (optimal for rack-to-rack links) without optical transceivers for cost-effective, low-power deployments in high-density switching fabrics.​

• Backward compatible with lower-speed QSFP+ modules via auto-negotiation.

Connectivity & Features

• Dual QSFP+ SFP+ compatible connectors (SFP to SFP) for plug-and-play installation on LANCOM routers/switches with QSFP+ ports, no external power required (powered by host device), and supports hot-swappable connections for maintenance without downtime.​

Design & Efficiency

• Flexible round twinax cable (0.23kg) with black sheathing for easy routing in tight spaces, operates from 0°C to 70°C with EMI shielding for reliable performance in server rooms, RoHS compliant for environmental standards.​
