The JBX05605 3-meter 100GBASE-CR4 QSFP28 to 4x SFP28 direct attach copper breakout cable is a purpose-built solution for enterprises and data centers leveraging Juniper networking equipment. This cable directly replaces the OEM Juniper part number JNP-100G-4X25G-3M, providing compatible performance at a fraction of the cost. **Technical Specifications:** This passive breakout DAC utilizes premium 28AWG twinax copper conductors enclosed in protective plastic jacketing. The QSFP28 connector aggregates four separate 25GB SFP28 connections into a unified 100GB interface, supporting 100GBASE-CR4 transmission standards. Qualified to IEEE 802.3bj and SFF-8665 specifications, it guarantees interoperability with Juniper infrastructure. **Key Features & Benefits:** Passive design eliminates active electronics, reducing power consumption and latency while lowering total cost of ownership. The 3-meter length accommodates typical rack-to-rack or intra-datacenter distances. RoHS, TUV, and UL certifications ensure environmental compliance and safety. Operating temperature range of 0-70°C provides reliable performance in diverse data center conditions. **Applications & Use Cases:** Ideal for connecting Juniper switches to servers, storage systems, or other network equipment requiring 100GB connectivity. Perfect for high-density data centers, cloud infrastructure, and enterprise networks. The breakout design enables flexible port management by converting single 100GB ports into four independent 25GB channels. **Why Choose This Cable:** Direct OEM compatibility ensures seamless integration without configuration issues. Passive construction offers superior reliability compared to active transceivers. Cost-effective solution for large-scale deployments. Backed by a 90-day limited warranty for peace of mind. **Shipping & Support:** Qualifies for free standard shipping on orders over $99. Ships from multiple US locations (Danville, CA and Beaufort, SC) for faster delivery. Custom brand programming available for enterprise clients requiring white-label solutions.
