The JBX03893 100GBASE-SR4 QSFP28 to 4x SFP28 Active Optical Breakout Cable represents the intersection of performance, reliability, and cost-effectiveness for next-generation network infrastructure. Designed as a direct replacement for Extreme Networks part number 10441-3M, this 3-meter optical cable enables seamless upgrades and expansions in existing network environments. **Technical Specifications:** This multimode active optical cable utilizes eight fiber strands (four bidirectional pairs) to transmit 100GB of data at SR4 wavelengths over OM3 50/125 fiber. The QSFP28 MSA-compliant form factor on the source end breaks out into four individual SFP28 connectors, making it ideal for applications requiring flexible port-to-port connectivity. The cable achieves IEEE 802.3bm compliance, ensuring interoperability with standards-based equipment. **Safety & Environmental Standards:** The LSZH (Low Smoke Zero Halogen) jacketing minimizes smoke generation and halogen gas release in event of fire, making it suitable for indoor installations and enclosed spaces. The cable carries multiple safety certifications including Class 1 Laser, TUV, UL/FDA 21CFR 1040.10, and LN #50 7/2001 compliance. RoHS and ELV directives compliance ensures environmental responsibility. **Application Use Cases:** Ideal for data centers, telecommunications facilities, high-performance computing clusters, and enterprise network upgrades. The breakout configuration is particularly valuable for architectures transitioning from 100G direct attach to distributed 25GB interfaces, or for applications requiring granular bandwidth management. **Reliability & Support:** Operating across a wide temperature range (0-70°C / 32-158°F), this cable withstands diverse deployment conditions. The 90-day limited warranty provides peace of mind, while custom brand programming options accommodate enterprise requirements. Free standard shipping on orders over $99 makes this solution cost-effective for bulk deployments.
