The JBX03639 20m Extreme Networks Compatible 40GBASE-AOC QSFP+ Active Optical Cable represents enterprise-grade connectivity solution for modern data center and campus network environments. Specifically engineered for compatibility with Extreme Networks equipment, this active optical cable eliminates the limitations of traditional copper cabling while delivering superior performance characteristics. Key Features & Specifications: This cable utilizes advanced OM3 50/125 multimode fiber technology supporting 40GB data rates as specified by IEEE 802.3ba standards. The 20-meter length accommodates typical rack-to-rack and cross-cabinet connectivity needs while minimizing signal degradation. With 8 fiber strands and precision-engineered plastic jacketing, the cable provides optimal signal integrity and durability. Safety & Compliance: Comprehensively certified for safety and regulatory compliance, including Class 1 Laser classification, UL/FDA approval per 21CFR 1040.10, and TUV certification. The LSZH (Low Smoke Zero Halogen) riser-rated (OFNR) jacketing ensures fire safety and reduced toxic emissions in enclosed spaces, meeting EU RoHS Directive 2002/95/EC standards. Performance Advantages: Active optical cables eliminate electromagnetic interference issues common with copper solutions and support longer distances without signal loss. Operating temperature range of 0-70°C ensures reliable performance across diverse environmental conditions. The QSFP+ form factor provides compact connectivity without sacrificing performance. Compatibility & Replacement: Directly replaces OEM part numbers including 40G-AOC-QSFP20M, making it an economical alternative to manufacturer-branded cables. Qualified for Extreme Networks switches and compatible with standard QSFP+ equipped network devices. Value Proposition: Shipped from convenient US locations (Danville, CA and Beaufort, SC), this cable qualifies for free standard shipping on orders exceeding $99. Custom brand programming is available for enterprise deployments requiring standardized labeling and identification.
