The JBX03899 50m Cisco QSFP-4X25G-AOC50M Compatible 100GBASE-SR4 Active Optical Cable represents cutting-edge connectivity solution for modern data center and enterprise network infrastructure. This premium breakout AOC cable delivers uncompromising performance for organizations requiring high-speed, reliable network communications. Technical Specifications & Architecture: This advanced active optical cable features a QSFP28 to 4x SFP28 breakout configuration, enabling flexible network configurations while maintaining 100GB aggregate data rates. The cable utilizes 8 fiber strands of OM3 50/125 multimode fiber, specifically optimized for short-to-medium reach applications in controlled indoor environments. At 50 meters in length, it provides extended reach capabilities beyond standard cable lengths while maintaining signal integrity and performance standards. Optical & Electrical Performance: Qualified to IEEE 802.3bm specifications and the QSFP28 MSA (Multi-Source Agreement), this cable delivers consistent 100GBASE-SR4 performance across all four channels. Each 25GB lane operates independently, providing redundancy and flexibility for network design. The OM3 fiber specification ensures compatibility with existing infrastructure investments while supporting future upgrades. Safety & Compliance Standards: Comprehensive safety certifications include Class 1 Laser designation, UL/FDA 21CFR 1040.10 compliance, and TUV verification. The LSZH (Low Smoke Zero Halogen) OFNR-rated PVC jacketing minimizes fire risk and toxic smoke emission, meeting building codes and safety regulations. Full RoHS/ELV directive compliance (EU 2002/95/EC) ensures environmentally responsible manufacturing and end-of-life disposal. Cisco Compatibility & Integration: As a direct compatible replacement for Cisco part number QSFP-4X25G-AOC50M, this cable integrates seamlessly with existing Cisco equipment and network architectures. No additional configuration or driver installation required—simply connect and operate. Ideal for Cisco Nexus switches, ASR routers, and compatible third-party hardware. Applications & Use Cases: - Data center east-west traffic optimization - High-speed interconnect between network switches - Server-to-switch 100G connectivity - Storage area network (SAN) deployments - Backbone network infrastructure upgrades - Research and academic institution networks Operational Advantages: Active optical technology eliminates EMI/RFI concerns associated with electrical cables, providing superior performance in electrically noisy environments. The 50-meter length reduces the need for intermediate equipment while maintaining signal quality. Operating temperature range of 0-70°C accommodates diverse deployment environments from cooled data center spaces to ambient office settings. Shipping & Support: Qualifies for free standard shipping on orders over $99, with convenient fulfillment from strategically located warehouses in Danville, CA and Beaufort, SC. Backed by comprehensive 90-day limited warranty and custom brand programming availability for qualified customers.
