The JBX03385 7m 400GBASE-SR8 QSFP-DD Active Optical Cable represents cutting-edge connectivity technology for demanding data center environments. As a purpose-built AOC solution, it combines fiber optic transmission with integrated electronics to deliver exceptional performance and reliability. **Technical Specifications:** This cable features 16 strands of OM3 50/125 multimode fiber encased in LSZH (Low Smoke Zero Halogen) plastic jacketing rated OFNR (Optical Fiber Non-Conductive Riser). Operating across IEEE 802.3cm specifications and QSFP-DD MSA standards, it achieves 400GB data rates essential for modern infrastructure. The 7-meter length accommodates flexible rack-to-rack deployments while maintaining signal integrity across moderate distances. **Compliance & Safety:** Manufactured to stringent standards including Class 1 Laser certification, TUV, UL/FDA (21CFR 1040.10), and RoHS/ELV directives. This comprehensive certification ensures safe operation in professional network environments while meeting international regulatory requirements. **Arista Compatibility:** Specifically engineered to replace OEM part number AOC-D-D-400G-7M, this cable integrates seamlessly with Arista switching platforms. Its plug-and-play design eliminates transceiver compatibility concerns, streamlining deployment and reducing operational overhead. **Applications & Use Cases:** Ideal for data center interconnects, high-performance computing clusters, storage area networks, and cloud service providers requiring 400G connectivity. The compact QSFP-DD form factor enables unprecedented port density while the 7m length accommodates standard data center spacing requirements. **Advantages Over Alternatives:** Unlike passive cable solutions requiring separate transceivers, this AOC integrates transmit/receive electronics, reducing cost and complexity. Superior to longer passive cables due to maintained signal integrity across the 7m span. OM3 multimode fiber offers cost advantages for shorter-distance deployments compared to single-mode alternatives. **Shipping & Support:** Qualifies for free standard shipping on orders exceeding $99, with fulfillment from Danville, CA or Beaufort, SC. Backed by 90-day limited warranty and custom brand programming available for enterprise customers. RoHS compliance ensures environmentally responsible procurement for sustainability-focused organizations.
