The JBX03854 represents a premium solution for organizations requiring flexible, high-capacity optical connectivity in modern network architectures. This 1-meter Cisco QSFP-4X25G-AOC1M compatible active optical cable addresses the critical need for port density conversion in data centers transitioning to 100GB infrastructure standards. **Cable Architecture & Design** This active optical breakout cable features an intelligent dual-function design that consolidates four independent 25GB SFP28 channels into a single QSFP28 connector interface. The 8-strand OM3 multimode fiber backbone supports simultaneous bidirectional transmission of low-voltage network signals, delivering consistent 100GBASE-SR4 performance across the full 1-meter span. The compact form factor (12x12x2mm) minimizes footprint while maintaining superior optical properties. **Material Specifications & Durability** Manufactured with precision-molded plastic jacketing and LSZH composition, this cable eliminates toxic fume emissions during combustion—a critical requirement for enclosed spaces, buildings, and dense rack environments. The OFNR (Optical Fiber Non-Conductive Riser) rating ensures full compliance with National Electrical Code (NEC) requirements for vertical cable runs and plenum-adjacent installations. Qualified manufacturing facilities in Vietnam and China ensure consistent quality and cost-efficiency. **Performance & Compatibility** Quarified to IEEE 802.3bm specifications and QSFP28 MSA standards, this cable integrates seamlessly with Cisco networking equipment and most mainstream switching platforms. Operating temperature range of 0-70°C (32-158°F) accommodates varied deployment scenarios from temperature-controlled data centers to industrial edge locations. The cable's OM3 multimode specification supports reliable transmission at 100GB speeds for standard-distance deployments. **Safety & Compliance** Comprehensive certifications include RoHS/ELV directive compliance, Class 1 Laser safety approval, UL/FDA validation per 21CFR 1040.10, and TÜV verification. These credentials ensure deployment in regulated industries and enterprise environments with strict compliance requirements. **Value Proposition** With free standard shipping on orders exceeding $99 and a straightforward 90-day limited warranty, this cable delivers enterprise-grade reliability at competitive pricing. Custom brand programming availability supports OEM partners and resellers seeking differentiated offerings. The QSFP28 breakout architecture enables cost-effective port expansion without disruptive equipment upgrades.
