## Summary description

Direct Attach Cable BlueOptics ET7402-DAC-5M is a 5-meter, copper 100GBASE-CR4 twinax assembly for short-range connections between network devices supporting 100 Gigabit Ethernet. It provides a fixed, low-latency link suitable for switches, routers and servers in data center top-of-rack or aggregation setups, requiring no additional transceivers or fiber termination.

## Long description

Direct Attach Cable BlueOptics ET7402-DAC-5M 100GBASE-CR4 5 m is a 5-metre copper twinax assembly designed for short-range 100 Gigabit Ethernet links. The fixed cable integrates connectors on both ends and implements the 100GBASE-CR4 electrical specification to provide a direct, low-latency connection between compatible switches, routers and servers. The cable is intended for data centre top-of-rack and aggregation deployments where a compact, cost‑effective and low-power alternative to active optical transceivers is required.
Advantages
The BlueOptics ET7402-DAC-5M offers a plug-and-play connection that requires no separate transceivers or fiber termination, reducing installation complexity. As a copper twinax solution it delivers low latency and stable signal integrity for short-reach links with predictable electrical performance. The integrated, fixed-length design simplifies inventory and cable management in dense rack environments while lowering power consumption compared with optical transceivers.
Suitable for
 Top-of-rack server to switch connections in data centres
 Switch-to-switch aggregation within the same equipment room
 High-performance server clusters requiring 100 Gigabit Ethernet
 Environments where low latency and predictable electrical performance are critical
Key specifications
 Standard: 100GBASE-CR4 electrical interface
 Media type: copper twinax fixed assembly
 Length: 5 m
 Connector type: integrated high-density 100G electrical connectors (fixed ends)
 Application range: short-reach data centre links
 Latency: low, suitable for high-throughput, low-latency environments
How to use
Install the BlueOptics ET7402-DAC-5M by plugging each integrated connector directly into the appropriate 100G ports on your network devices. Ensure both devices support 100GBASE-CR4 electrical signaling and that port configurations match (speed, lane mapping, and any vendor-specific compatibility notes). Route the fixed cable through rack channels or cable organizers to avoid sharp bends and mechanical strain, and verify link status and performance through device management interfaces after connection.
Usage recommendations
Use the cable only for short-range electrical 100G links inside equipment rooms and racks. Avoid tight bends, excessive pulling force and exposure to moisture or corrosive environments. Confirm compatibility with device vendor documentation for 100GBASE-CR4 ports before deployment and keep spare fixed-length assemblies to simplify maintenance and replacements.
