BLUELAN Cable de conexión directa 50G SFP56 compatible con HPE Aruba R0M46A, 0,5m, cable de cobre twinaxial pasivo

In dense data centers and high-performance computing environments, achieving reliable 50 Gigabit Ethernet connectivity over short distances without excessive power draw or latency is a constant challenge. The BLUELAN R0M46A-BL Direct Attach Cable (DAC) solves this by providing a passive twinaxial copper link that directly connects SFP56 ports on switches, servers, and storage devices. This 0.5-meter cable is fully compatible with HPE Aruba R0M46A transceivers and other SFP56-equipped hardware, delivering a cost-effective, low-latency alternative to optical modules for rack-to-rack and server-to-switch interconnects.

Who is it for

This DAC is ideal for IT administrators, data center managers, and network engineers who need to establish high-speed 50GbE links within a rack or between adjacent racks. It is perfect for top-of-rack (ToR) switching, storage area networks (SAN), and high-frequency trading platforms where every microsecond counts and power budgets are tight.

Main features

• Passive twinaxial copper design: No external power required, reducing energy consumption and heat generation.
• 50 Gbps data transfer rate: Supports 50 Gigabit Ethernet (50GbE) for bandwidth-intensive applications.
• SFP56 to SFP56 connectors: Direct attach to compatible ports without additional transceivers.
• 0.5-meter length: Ideal for short-reach connections within and between racks.
• Hot-plug support: Allows for easy installation and replacement without downtime.
• 100 Ohm impedance: Ensures signal integrity and compliance with industry standards.
• SFF-8402 compliant: Meets the specifications for SFP56 direct attach cables.

Tips

To ensure optimal performance, verify that your equipment supports SFP56 ports and 50GbE speeds. Keep the cable bend radius above the manufacturer's recommendation (typically 30mm for passive DACs) to avoid signal degradation. For longer distances beyond 3 meters, consider active optical cables (AOCs) instead.
