## Long description

The BlueLAN QSFP-40G-2M-CM is a 2-meter QSFP 40GBASE-CR4 direct attach cable engineered for short-reach, high-bandwidth connections in Ethernet and InfiniBand environments. Constructed with 30AWG conductors and a QSFP connector interface, this cable provides a straightforward copper connection between compatible QSFP ports, enabling 40 Gbps links with low latency and stable signal integrity. Its blue jacket and compact form factor are typical for rack and server deployments where reliable, cost-effective cabling is required.
Advantages
This direct attach cable offers predictable performance for 40 Gbps links without requiring separate transceivers, reducing both equipment and power costs. The 2-meter length balances flexibility and signal quality for cabling between adjacent racks or within server cabinets. With 30AWG construction and industry-standard QSFP termination, the cable maintains consistent electrical characteristics suitable for high-density networking setups.
Suitable for
Connecting QSFP ports on switches and routers in data centers
Linking servers to top-of-rack or leaf switches
Short-reach high-bandwidth links for Ethernet and InfiniBand fabrics
High-density rack cabling where space and power efficiency matter

How to use
Install the cable by inserting the QSFP connectors into compatible QSFP ports on network equipment until the connector latch engages. Ensure both ends are securely seated and that the connected devices are configured for a 40GBASE-CR4 link.

Usage recommendations
For reliable operation, use this cable for short-reach connections within the same rack or between adjacent racks. Avoid sharp bends and exposure to mechanical stress; keep the cable clear of power-carrying cable bundles to reduce EMI risks. Verify compatibility with your network hardware’s QSFP ports and firmware versions before deployment to ensure link negotiation and power budgets align with equipment requirements.
