The JBX04319 represents a critical infrastructure component for modern high-speed data center deployments. This 20-meter 200GBASE-SR4 QSFP56 Active Optical Cable delivers exceptional performance as a direct replacement for the Arista A-Q200-Q200-20M specification, making it an ideal choice for organizations standardizing on Arista switching platforms. **Technical Specifications:** Designed with eight strands of OM3 50/125 multimode fiber, this AOC supports data rates up to 200GB/s, meeting demanding bandwidth requirements of contemporary networking infrastructure. The QSFP56 form factor ensures compatibility with next-generation switching equipment, while CMIS (Common Management Interface Specification) support provides enhanced diagnostics and monitoring capabilities. **Safety & Compliance:** The cable meets stringent safety standards including Class 1 Laser certification (ANSI Z136.1), UL/FDA approval per 21CFR 1040.10, and TUV certification. Full RoHS compliance (EU Directive 2002/95/EC) and LSZH jacketing eliminate hazardous substances and reduce smoke emissions in confined spaces—critical for data center fire safety protocols. **Installation & Durability:** The OFNR (Optical Fiber Non-Conductive Riser) rating permits installation in vertical cable runs and plenums. Operating across 0-70°C temperature ranges, this cable maintains signal integrity through standard data center environmental conditions. The flexible plastic jacketing facilitates easy routing through existing infrastructure without requiring specialized installation tools. **Application Scenarios:** Ideal for inter-switch connectivity, high-density server cluster connections, and storage area network (SAN) deployments. The 20-meter length accommodates typical data center rack-to-rack distances while minimizing signal degradation. Organizations requiring Arista ecosystem compatibility benefit from guaranteed interoperability and simplified inventory management. **Warranty & Support:** Backed by a comprehensive 90-day limited warranty, with convenient shipping from Danville, CA or Beaufort, SC distribution centers. Custom brand programming is available for organizations requiring specialized identification or tracking requirements.
