## Summary description

BlueOptics direct attach cable model 980-9I621-00C002 is a 2-meter 100GBASE-CR4 Ethernet passive copper assembly with 30AWG conductors. Designed for short-reach 100 Gigabit Ethernet connections between switches, routers or NICs supporting CR4, it provides a low-latency, cost-effective link for data center interconnects, server racks and aggregation points.

## Long description

BlueOptics 980-9I621-00C002 is a 2‑meter Direct Attach Cable (DAC) specified for 100GBASE-CR4 Ethernet connections. This passive copper assembly uses 30AWG conductors and is intended for short-reach, high-bandwidth links between switches, routers and network interface cards (NICs) that support CR4. The cable offers low latency and predictable electrical performance for data center interconnects, top-of-rack and aggregation deployments where a cost-effective, fixed-length copper solution is required.
Advantages
This BlueOptics 100GBASE-CR4 DAC provides a plug-and-play connection with no additional optics required, reducing component count and simplifying installation. The passive design lowers power consumption compared with active optical transceivers and supports reliable signal integrity over short distances thanks to its 30AWG conductors. With a fixed 2 m length and rugged connector housings, the cable is suited for dense rack environments and minimizes link variability between compatible ports.
Suitable for
 Short-reach 100 Gigabit Ethernet links in data center racks
 Interconnects between switches, routers and NICs supporting CR4
 Top-of-rack to aggregation switch connections
 High-density deployments where low-latency copper links are preferred
Key specifications
 Ethernet standard: 100GBASE-CR4
 Length: 2 meters
 Conductor size: 30AWG
 Cable type: Passive copper direct attach assembly
 Connector style: CR4-compatible high-density QSFP form-factor interface (assembly designed for 100G CR4 ports)
 Intended reach: short-reach data center links
How to use
Install the BlueOptics DAC by plugging each connector directly into the corresponding 100G CR4-compatible ports on switches, routers or NICs. Ensure both endpoints support 100GBASE-CR4 and that port firmware/settings permit passive DAC operation. Route the cable to avoid sharp bends and maintain recommended bend radii for 30AWG copper assemblies. No additional transceivers or power sources are required for operation.
Usage recommendations
Verify compatibility with network equipment vendor documentation before deployment, and test the link after installation to confirm expected throughput and latency. For cable management, use horizontal/vertical organizers to prevent stress on connectors and to preserve signal integrity in high-density racks.
