The JBX04008 20-meter HPE-compatible 100GBASE-SR4 QSFP28 active optical cable represents the pinnacle of high-speed network connectivity solutions for enterprise and data center environments. Engineered to meet the demanding requirements of modern network infrastructure, this cable delivers exceptional performance, reliability, and compatibility. **Performance Specifications:** Operating at 100GB data rates, this QSFP28 active optical cable utilizes OM3 50/125 multimode fiber with eight individual strands to ensure optimal signal transmission. The cable is fully qualified to IEEE 802.3bm specifications and QSFP28 MSA standards, guaranteeing interoperability with HPE systems and other compliant hardware. **Construction and Safety:** The cable features a durable plastic jacket with Low Smoke Zero Halogen (LSZH) composition, meeting OFNR (Optical Fiber Non-conductive Riser) ratings for installation in vertical pathways and spaces. Multiple safety certifications including Class 1 Laser, UL, FDA 21CFR 1040.10, and TUV compliance ensure safe operation in controlled environments. **Environmental Compliance:** Fully RoHS (Restriction of Hazardous Substances) and ELV (End of Life Vehicles) compliant, this cable meets EU Directive 2002/95/EC requirements, making it suitable for environmentally conscious organizations and regulated industries. **Compatibility and Replacement:** Direct replacement for multiple OEM part numbers including Q9S71A-20M, JL278A, 845414-B21-20M, and 834972-B27. The 20-meter length provides flexibility in data center layouts while the active optical design eliminates attenuation concerns over longer distances. **Use Cases:** Ideal for connecting HPE switches, routers, and storage systems requiring 100GB interconnectivity. Perfect for data center infrastructure, high-performance computing clusters, and enterprise campus networks where reliability and speed are paramount. **Warranty and Support:** Backed by a 90-day limited warranty, with free standard shipping on orders exceeding $99. Ships from multiple distribution centers (Danville, CA and Beaufort, SC) ensuring rapid delivery. **Technical Advantages:** Active optical technology provides superior signal integrity compared to passive alternatives, particularly valuable for longer cable runs. The 12mm cable diameter maintains compact pathway routing while the eight-strand fiber core ensures redundancy and reliability in critical network deployments.
