The JBX03883 represents enterprise-class connectivity for modern data center and campus network infrastructure. Designed as a direct replacement for Cisco's QSFP-4X25G-AOC30M, this 30-meter active optical breakout cable delivers the performance and reliability required by mission-critical applications. **Advanced Optical Technology:** Utilizing OM3 50/125 multimode fiber in an 8-strand configuration, this cable leverages active optical amplification to overcome distance limitations inherent in passive alternatives. The 30-meter length exceeds typical intra-datacenter requirements while maintaining signal integrity across all four 25GB channels. **Superior Safety & Compliance:** The OFNR (Riser) LSZH jacket provides enhanced fire safety suitable for installation through building risers and enclosed spaces. Complete RoHS and EU directive 2002/95/EC compliance ensures environmentally responsible manufacturing. Class 1 laser safety certification, TUV, UL/FDA, and 21CFR 1040.10 approvals demonstrate rigorous quality validation. **Flexible Network Architecture:** The QSFP28-to-4x-SFP28 breakout design enables equipment migration strategies and heterogeneous network configurations. Organizations can transition existing 25GB infrastructure while deploying new 100GB aggregation, maximizing ROI on network investments. **Performance Specifications:** - Qualified to IEEE 802.3bm and QSFP28 MSA standards - Supports 100GBASE-SR4 transmission protocols - Zero skew channel design ensures synchronized signal delivery - Operating temperature range: 0-70°C (32-158°F) **Installation & Maintenance:** Direct compatibility with standard Cisco QSFP28 and SFP28 ports eliminates adapter complexity. The robust plastic jacketing with fiber strand protection ensures durability in typical rack-and-stack environments. 90-day limited warranty provides confidence in equipment reliability. **Custom Branding Available:** Organizations requiring branded network infrastructure can access custom programming options for enterprise deployments. Ideal for: Data centers, enterprise campus networks, service provider environments, and high-performance computing clusters requiring extended-reach 100GB breakout connectivity.
