Cable de cobre de conexión directa (DAC) CBO 740-038623 1 m QSFP para Juniper

BlueOptics Direct Attach Copper (DAC) Cable CBO 740-038623 is a 1 m QSFP copper interconnect designed for short-reach, high-speed links in data center environments. The cable provides a direct, fixed copper connection for devices with QSFP ports and is intended to deliver low latency and reliable performance for server-to-switch or switch-to-switch connections. The plug-and-play form factor requires no additional transceivers, simplifying installation and reducing component count.

Advantages

The DAC cable offers a cost-effective and energy-efficient option for short-distance high-bandwidth connectivity. Its fixed copper design minimizes power consumption compared with active optical solutions and avoids the need for separate transceiver modules. With a 1 m length and QSFP connectivity, the cable supports straightforward, low-latency links and a compact physical footprint that helps maintain clean rack and patch panel routing.

Suitable for

• Server-to-switch connections in top-of-rack and end-of-row deployments
• Switch-to-switch aggregation within the same rack or adjacent racks
• High-throughput short-reach links in data centers and network closets
• Environments where low latency and reduced power draw are priorities

Key specifications

• Cable type: Direct attach copper (DAC)
• Connector type: QSFP on both ends
• Length: 1 meter
• Use case: Short-reach, fixed copper interconnect for high-speed ports
• Compatibility: Designed for QSFP ports in compatible network equipment

How to use

Install the DAC cable by inserting each QSFP connector into the corresponding QSFP port on the devices to be connected, ensuring the connector latch engages. Because this is a fixed direct-attach cable, no additional transceivers or module configuration is required. After physical connection, verify link status and speed through the device management interface or LED indicators. For best results, route the cable to avoid sharp bends and excessive strain on the connectors.

Recommendations

Use this 1 m QSFP DAC cable for short, high-bandwidth links in the same rack or neighboring racks. Ensure QSFP port compatibility on your Juniper or other network devices, verify firmware and hardware support for direct-attach copper cables, and avoid installing the cable near sources of strong electromagnetic interference to preserve signal integrity.
