Suitable for data centers and rack-to-rack connections where a short, cost-effective 100G link is required.

## Long description

Direct attach copper (DAC) cable CBO BlueOptics 740-061000-BL QSFP28 to QSFP28 is a 1 m passive assembly engineered for 100G short-reach connections. This QSFP28 to QSFP28 cable supports native 100 Gigabit Ethernet links between compatible switches, routers and servers without requiring separate transceiver modules. Its fixed, low-latency copper construction is intended for rack-to-rack and intra-rack interconnects in data centers and network closets where a compact, cost-effective 100G link is needed.
Advantages
The cable delivers reliable 100G performance with minimal power consumption because it is a passive DAC solution that does not require active electronics or additional optics. Its QSFP28 connectors ensure compatibility with equipment that accepts direct-attach copper assemblies, simplifying deployment and reducing total cost of ownership. The 1 m length reduces signal attenuation for short-distance links and keeps cable management tidy in dense rack environments.
Suitable for
 Short-reach 100G links between top-of-rack and aggregation switches
 Direct server-to-switch connections in data centers
 Rack-to-rack high-speed interconnects
 Test lab setups requiring reliable 100G connectivity
Key specifications
 Connector type: QSFP28 to QSFP28
 Link speed: 100 Gigabit Ethernet
 Length: 1 m
 Cable type: Passive direct attach copper (DAC)
 Typical application: Short-reach, rack-level interconnects
 Latency: Low (passive copper design)
How to use
Install the DAC cable by inserting each QSFP28 connector into the corresponding QSFP28 port on your networking equipment until the latch engages. Confirm link status through the device management interface and ensure matching 100G port settings on both endpoints. No separate transceivers, fiber patching or optical modules are required. For safe removal, release the connector latches before pulling the cable straight out to avoid damaging the port or connector.
Usage recommendations
Use this 1 m passive QSFP28 DAC in short-distance connections inside racks or between adjacent racks. Avoid tight bends and excessive strain on the cable; maintain bend radii recommended by equipment vendors. Verify equipment compatibility with QSFP28 passive copper assemblies and ensure ports are configured for 100G operation to achieve optimal performance.
