The JBX03837 is a professional-grade 10-meter active optical cable that represents the ideal solution for modern data center networks requiring flexible, high-speed connectivity. As a direct Cisco QSFP-4X25G-AOC10M replacement, this cable delivers proven compatibility and reliable performance in demanding network environments. Technical Specifications: This QSFP28-to-4x SFP28 breakout cable operates at 100GB total bandwidth (25GB per SFP28 channel) and fully complies with IEEE 802.3bm and QSFP28 MSA standards. The cable features eight strands of OM3 50/125 multimode fiber, delivering optimal signal integrity across the 10-meter distance. The construction includes plastic jacketing with LSZH material, meeting safety requirements in sensitive environments and reducing smoke/toxin emission in case of fire. Design & Build Quality: With dimensions of 12x12x10mm, this compact cable fits easily into crowded network cabinet spaces. The OFNR (Riser Rated) designation indicates suitability for installation in building risers and plenum spaces. RoHS/ELV compliance ensures environmental responsibility, while multiple safety certifications—including UL, FDA, TÜV, and Class 1 laser classification—demonstrate quality assurance and regulatory adherence. Application & Benefits: Data center managers, network engineers, and IT professionals benefit from this cable's flexibility. Rather than investing in entirely new switching infrastructure, organizations can implement this breakout cable to expand port density and improve network scalability. The active optical design eliminates copper's electromagnetic interference concerns while maintaining superior performance over the 10-meter span. Operational Performance: Qualified for continuous operation between 0-70°C (32-158°F), this cable accommodates diverse environmental conditions typical in server rooms and network closets. The 90-day limited warranty provides confidence in product reliability, while the available custom brand programming option allows for asset management integration. Shipping & Availability: Free standard shipping applies to orders exceeding $99, with fulfillment from established logistics centers in Danville, CA and Beaufort, SC, ensuring quick delivery. Whether upgrading existing installations or deploying new infrastructure, this Cisco-compatible AOC cable delivers professional-grade performance at competitive pricing.
