Suitable for compact, low-latency 100 GbE interconnects.

## Long description

BlueOptics QSFP28 Direct Attach Cable 1 m provides a 100GBASE-CR4 Ethernet connection over 30AWG twinax copper wiring. Intended for QSFP28 ports, this 1-m direct-attach cable supports short-reach, high-bandwidth links between servers and switches or between switches in data centers and network racks. The cable is designed for compact deployments where low latency and reliable 100 GbE interconnects are required.
Advantages
The cable delivers a native 100GBASE-CR4 electrical interface with low insertion loss and predictable signal performance for short-reach connections. Its direct-attach QSFP28 form factor eliminates the need for optical transceivers, reducing system cost and power consumption for in-rack interconnects. The 1 m length and 30AWG conductor gauge provide a balance of flexibility and density suited to closely spaced equipment, while the fixed twinax assembly simplifies installation and minimizes points of failure.
Suitable for
 Short-reach 100 GbE links between servers and top-of-rack switches
 Switch-to-switch connections inside data center racks
 High-density network deployments requiring low-latency interconnects
 Environments where a direct-attach electrical solution is preferred over optical transceivers
Key specifications
 Interface: QSFP28 to QSFP28
 Protocol: 100GBASE-CR4 (electrical)
 Length: 1 meter
 Conductor gauge: 30AWG twinax
 Cable type: Direct attach copper twinax assembly
 Typical use: Short-reach server-to-switch and switch-to-switch interconnects
How to use
Insert each QSFP28 connector into the corresponding port on the two devices until the connector latch engages. Ensure both ports support 100GBASE-CR4 over direct-attach copper and that devices are powered and configured for 100 GbE operation. Avoid sharp bends near the connector ends and allow some slack to prevent mechanical strain. For removal, depress the latch and pull the connector straight out without twisting.
Usage recommendations
Use this 1 m QSFP28 direct-attach cable for in-rack, short-distance links where consistent 100 GbE performance and minimal latency are required. Verify compatibility with your switch or server QSFP28 port specifications and ensure airflow and cable routing do not obstruct cooling in dense rack setups.
