The JBX03890 3-meter 100GBASE-SR4 QSFP28 active optical breakout cable represents a cost-effective solution for modern data center infrastructure requiring high-speed, reliable connectivity. This cable is engineered as a direct compatibility replacement for Arista's AOC-Q-4S-100G-3M, making it an ideal upgrade or spare component for existing Arista network deployments. **Technical Specifications:** This breakout AOC features a single QSFP28 connector that splits into four SFP28 connectors, utilizing 8 strands of OM3 50/125 multimode fiber. The 3-meter length provides optimal flexibility for rack-to-rack and switch-to-switch interconnections within standard data center layouts. Operating at 100GB aggregate bandwidth, the cable meets IEEE 802.3bm and QSFP28 MSA standards, ensuring compatibility across certified equipment. **Quality & Compliance:** Constructed with premium materials and LSZH (low-smoke, zero-halogen) jacketing rated for riser (OFNR) applications, this cable meets stringent fire safety requirements for commercial building installations. The cable carries multiple safety certifications including Class 1 Laser approval, TUV certification, and FDA 21CFR 1040.10 compliance. Full RoHS and EU directive 2002/95/EC compliance ensures environmental responsibility. **Performance & Reliability:** With an operating temperature range of 0-70°C (32-158°F), this cable maintains consistent performance across diverse deployment environments. The robust plastic jacketing protects fiber strands from damage while the multimode fiber technology minimizes signal loss over the 3-meter distance, critical for high-speed data transmission. **Applications:** Ideal for data center operators, network administrators, and IT professionals implementing or upgrading Arista-based infrastructure. Perfect for server-to-switch connections, storage area network (SAN) implementations, and enterprise cloud deployments requiring 100GB connectivity. **Warranty & Support:** Backed by a 90-day limited warranty and available with custom brand programming options for enterprise deployments. Free standard shipping on orders exceeding $99, with convenient shipping from multiple U.S. locations.
