BlueLAN 0,5m 400G OSFP na OSFP pasívny Direct Attach medený twinaxiálny kábel, kompatibilný s Arista

In dense data centers, connecting 400G OSFP ports across adjacent racks often requires a reliable, low-latency link without the cost and power draw of optical transceivers. This BlueLAN direct attach cable provides a passive twinaxial copper solution, engineered for Arista CAB-O-O-400G-0.5M compatibility, delivering 400 Gigabit Ethernet over a short 0.5-meter reach.

Who is it for

Network engineers and data center operators deploying Arista switches and routers with OSFP interfaces who need a cost-effective, low-power interconnect for top-of-rack to adjacent rack or intra-rack cabling. Ideal for high-density 400G fabrics where latency and power efficiency are critical.
