The JBX03440 represents a superior solution for enterprises requiring high-speed optical connectivity in Juniper-based network architectures. As a direct replacement for Juniper's OEM part number JNP-QSFP-4XLC-25M, this Active Optical Cable combines cutting-edge fiber optic technology with proven reliability and industry-standard compliance. **Technical Excellence:** This 25-meter 40GBASE-SR4 QSFP+ AOC utilizes premium OM3 50/125 multimode fiber with 8 strands, delivering consistent 40GB data rates across all connected channels. The cable's active components ensure signal integrity over the full 25-meter distance, eliminating signal degradation common in passive alternatives. Operating across a wide temperature range of 0°C to 70°C (32°F to 158°F), it maintains performance in diverse data center environments from standard air-cooled facilities to hot-aisle installations. **Superior Safety & Compliance:** Manufactured to the strictest safety standards, the JBX03440 features Class 1 Laser certification, UL/FDA approval per 21CFR 1040.10, and TUV qualification. Its LSZH jacketing minimizes smoke and toxic halogen release in fire situations, making it ideal for secure facilities and compliance-sensitive environments. Full RoHS and ELV directive adherence ensures environmental responsibility without compromising performance. **Design & Compatibility:** The intelligent breakout design provides flexibility—one QSFP+ connection feeds four independent LC duplex fiber paths, simplifying network topology and reducing connector clutter. The plastic jacketing with integrated fiber protection ensures durability during installation and maintenance. This Juniper-compatible cable integrates seamlessly with existing network infrastructure. **Applications:** Perfect for data center interconnects, high-speed server connections, storage area networks (SANs), and campus backbone networks. The 25-meter length spans between equipment racks and adjacent facility zones efficiently. Backed by a 90-day limited warranty and available with custom brand programming, this cable represents a cost-effective alternative to OEM solutions without sacrificing quality or performance. **Free Shipping:** Orders exceeding $99 qualify for complimentary standard shipping from our California or South Carolina distribution centers, ensuring rapid deployment of your network infrastructure.
