Cable DAC CBO JNP-100G-DAC-50CM 50 cm QSFP28 cable de cobre de conexión directa

CBO JNP-100G-DAC-50CM 50 cm QSFP28 direct-attach copper is a short-reach, high-bandwidth cable that provides a direct QSFP28-to-QSFP28 connection for 100 Gigabit Ethernet links. The 50 cm copper assembly is intended for use in environments where low latency and reliable, high-throughput connections are required without the need for separate optical transceivers. It is suitable for dense data center deployments and equipment racks where space, power efficiency and cost-effectiveness are priorities.

Advantages

This DAC cable offers a compact, low-latency physical connection that eliminates the power and cost overhead of transceivers. The QSFP28 form factor supports full 100G bandwidth over a short distance with consistent signal integrity and reduced heat generation compared with active optical modules. The 50 cm length minimizes cable clutter in racks and simplifies cable management for top-of-rack and aggregation links.

Suitable for

• Top-of-rack switch-to-switch connections in data centers
• Switch-to-server or switch-to-router short links
• High-density rack installations requiring low latency
• Cost-sensitive short-range 100G deployments

Key specifications

• Connector type: QSFP28 to QSFP28
• Data rate: 100 Gbps
• Cable type: Direct-attach copper (DAC)
• Length: 50 cm
• Reach: short-reach / intra-rack connectivity
• Form factor: passive copper assembly (low power)

How to use

Insert each QSFP28 connector into the appropriate port on the two networking devices until the latch engages. Verify link status through the device management interface and ensure port configurations match 100G operation. Because the cable is a passive copper assembly, there is no separate power or module setup required. Use appropriate ESD precautions when handling and install in a way that avoids sharp bends and excessive tension on the cable.

Recommendations

Prefer this 50 cm DAC for intra-rack and short aggregation links where 100G bandwidth is needed with minimal power and cost. Avoid using the cable beyond recommended short-reach applications; maintain bend radius and secure routing to preserve signal integrity and connector life.
