The JBX03514 30-meter Cisco QSFP+ active optical cable represents the optimal solution for organizations requiring high-speed, reliable 40 Gigabit Ethernet connectivity in modern data center and enterprise environments. This purpose-engineered breakout AOC cable combines exceptional performance with practical flexibility, delivering 40GBASE-SR4 speeds across 30 meters of OM3 multimode fiber. **Key Technical Features:** This active optical cable utilizes advanced 8-strand OM3 50/125 multimode fiber technology, enabling simultaneous transmission of four 10 Gigabit channels through a single QSFP+ interface. The cable's breakout architecture—one QSFP+ to four SFP+ connectors—allows seamless integration with existing infrastructure while reducing space requirements in densely packed rack environments. **Performance & Compliance:** Qualified to IEEE 802.3ba specifications, this cable guarantees 40 gigabit-per-second data rates with minimal latency and signal degradation. Operating across the 0-70°C temperature range ensures reliable performance in variable data center climates. Safety certifications include Class 1 Laser, UL/FDA (21CFR 1040.10), and TUV compliance, while RoHS directive compliance (2002/95/EC) ensures environmental responsibility. **Installation Advantages:** The OFNR (Riser Rated) LSZH jacketing provides superior fire safety properties, meeting building code requirements for in-wall installations without conduit. The compact 12x12x30mm form factor minimizes cable bulk, simplifying cable management and reducing congestion in server racks and patch panels. **Ideal Applications:** Perfect for upgrading legacy fiber networks to 40G capability, implementing high-speed storage area networks (SANs), connecting enterprise switches, or building resilient cloud infrastructure. The Cisco compatibility ensures plug-and-play deployment without driver or firmware complications. **Value Proposition:** With free standard shipping on orders exceeding $99 and warehousing in strategic US locations (Danville, CA and Beaufort, SC), this cable delivers both performance and convenience. Custom brand programming options accommodate OEM requirements, while the 90-day limited warranty provides purchase confidence for mission-critical deployments.
