Tripp Lite QSFP+ to 10 GbE SFP+ Passive DAC Breakout Cable (M/M), QSFP+ to (x4) SFP+, Compatible to Cisco QSFP-4SFP10G-CU1M, 1M (3.28 ft.)

Overview

The Tripp Lite N281-01M-BK is a 1-meter passive direct attach copper breakout cable designed to convert a single QSFP+ 40 GbE port into four independent SFP+ 10 GbE connections. This cable is ideal for expanding bandwidth from spine or aggregation switches to servers, storage devices, or top-of-rack switches within the same cabinet. Supporting an aggregate data rate of up to 40 Gbps, it ensures high-speed data transfer for demanding applications like backups, virtualization, and database replication without adding latency.

Key features

• Splits one QSFP+ 40 GbE port into four separate 10 GbE SFP+ links, increasing port density efficiently
• Passive copper design eliminates the need for external power or transceivers, reducing operating costs
• Zinc die cast connectors shield against electromagnetic interference, maintaining signal integrity in dense data centers
• Pull-tab ejectors provide easy connector insertion and removal in crowded switch panels without special tools
• Flexible eight-pair, 30 AWG conductor design simplifies routing through cable managers and tight spaces
• Complies with MSA SFF-8431 and SFF-8436 standards for broad compatibility with open-standards networking equipment
• Pinout matches Cisco QSFP-4SFP10G-CU1M, ensuring seamless integration in mixed-vendor environments
• Compatible with SDR, DDR, and QDR InfiniBand equipment, supporting high-performance computing clusters
