The JBX03290 20m 400GBASE-SR8 QSFP-DD Active Optical Cable represents the cutting edge of high-speed network connectivity technology. Engineered specifically for Arista-compatible systems, this cable delivers exceptional performance and reliability for mission-critical data center and enterprise network applications. **Technical Specifications:** This active optical cable features 16 strands of OM3 50/125 multimode fiber, designed to support 400GB Ethernet transmission at distances up to 20 meters. The QSFP-DD form factor ensures compatibility with the latest generation of network equipment, while adherence to IEEE 802.3cm and CMIS standards guarantees interoperability across diverse network architectures. **Superior Safety and Compliance:** The cable is constructed with LSZH (Low Smoke Zero Halogen) jacketing material, reducing toxic smoke and corrosive gas emissions in the event of fire—critical for installations in enclosed spaces and compliance-sensitive environments. Class 1 Laser certification and UL/FDA compliance (21CFR 1040.10) demonstrate our commitment to user safety and regulatory adherence. Full RoHS and EU directive 2002/95/EC compliance ensures environmental responsibility. **Performance and Durability:** Operating reliably across a temperature range of 0-70°C (32-158°F), this cable maintains consistent performance in diverse deployment scenarios. The robust plastic jacketing protects fiber strands from environmental stress, while the multimode fiber construction provides optimal signal integrity and minimal attenuation over the 20-meter span. **Ideal Applications:** • Data center interconnects and backbone networks • High-speed campus network connections • Storage area network (SAN) deployments • Cloud computing infrastructure • Enterprise server room upgrades • Arista network switch connections **Value and Support:** This cable replaces OEM part number AOC-D-D-400G-20M and includes a 90-day limited warranty. Custom brand programming is available for OEM requirements. Ships from convenient US locations (Danville, CA or Beaufort, SC) with free standard shipping on orders exceeding $99, making this premium cable an accessible solution for growing network infrastructure needs.
