## Summary description

The BlueOptics R1N34A compatible BlueLAN DAC QSFP28 cable offers high-speed data transmission with a length of 0.5 meters. It features QSFP28 connectors, ensuring compatibility with various devices. This cable is designed for optimal performance in data centers and networking environments, providing reliable connectivity and reduced latency. Its durable construction ensures longevity and stability in demanding applications.

## Long description

The BlueOptics R1N34A compatible BlueLAN DAC QSFP28 cable delivers high-speed, short-reach connectivity for data center and enterprise network environments. At 0.5 meters length and fitted with QSFP28 connectors, this direct attach cable is engineered for low latency and stable signal transmission between QSFP28 ports. Its compact form factor and robust construction make it suitable for high-density switch-to-switch, switch-to-server, or server-to-server connections where reliable 100GbE links are required.
Advantages
This QSFP28 direct attach cable provides predictable performance with minimal signal loss and reduced latency compared with longer optical runs. The short 0.5 m length minimizes crosstalk and electrical interference in dense rack deployments. Designed for interoperability, the cable offers physical compatibility with standard QSFP28 ports and a sturdy jacket and strain relief for extended mechanical durability in frequent-move or high-vibration environments.
Suitable for
Short-reach 100GbE links in data centers and server rooms
High-density switch-to-switch or switch-to-server connections
Top-of-rack (ToR) cabling and patching within racks
Environments requiring low latency and stable throughput
Key specifications
Connector type: QSFP28 to QSFP28
Length: 0.5 meters
Supported link speed: 100 Gigabit Ethernet (100GbE)
Cable type: Direct attach copper (DAC) assembly
Design focus: Low latency, short-reach connections
How to use
Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port until the latch engages. Ensure both network devices are powered and that port configurations (speed, lane mapping, and firmware compatibility) support QSFP28 passive DAC operation. Route the cable to avoid tight bends and excessive mechanical stress; keep the length appropriate for the intended top-of-rack or short-reach patching application. No additional transceivers or optical modules are required for operation.
Usage recommendations
Verify compatibility with your switch or server vendor and confirm port settings before deployment. For reliable performance, maintain bend radii above the manufacturer’s minimum and avoid running the cable near high-power electrical sources. Use short DACs like this 0.5 m QSFP28 assembly for intra-rack connections and reserve optical transceivers for longer links.
