Tripp Lite QSFP28 to QSFP28 100GbE Passive DAC Cable (M/M), QSFP-100G-CU1M Compatible, 1M (3.28 ft.)

Overview

The Tripp Lite N282-01M-28-BK is a QSFP28 to QSFP28 passive direct attach copper (DAC) cable designed to deliver a full 100 Gbps connection over a short distance of one meter. It provides a high-speed copper link ideal for connecting switches, blade servers, or top-of-rack aggregation equipment without the need for separate transceivers or fiber optics. This cable supports 100GBASE-CR4 standards and merges four 28 Gbps SFP lanes into a single interface, simplifying your network setup while maintaining low latency and reducing costs.

Key features

• Delivers a 100 Gbps connection using passive copper, eliminating the need for power-hungry optical transceivers.
• One-meter length keeps short-range connections organized and minimizes signal delay.
• Complies with 100GBASE-CR4 and MSA SFF-8665 standards for reliable interoperability.
• Compatible with Cisco QSFP-100G-CU1M and similar QSFP28 ports, ensuring seamless integration in mixed-vendor environments.
• Supports 128G Fibre Channel and EDR InfiniBand protocols, making it suitable for converged networks handling Ethernet, storage, and HPC traffic.
• Constructed with 26 AWG conductors and zinc die-cast connectors to maintain signal integrity and resist electromagnetic interference.
• Pull-tab ejectors allow quick, tool-free installation and removal, which is especially useful in dense rack environments.
• Consumes less power and reduces port costs compared to equivalent fiber optic solutions, helping to optimize data center efficiency.
