The JBX01078 400GBASE-SR8 QSFP-DD transceiver represents cutting-edge optical transmission technology for next-generation data center and enterprise networking. This module is specifically designed to meet the demands of ultra-high-speed network infrastructure requiring 400GB connectivity over multimode fiber installations. Key Performance Specifications: Operating at 850nm wavelength, this SR8 transceiver delivers 400GB data rates with an impressive 100-meter reach over OM4 multimode fiber. The QSFP-DD (Quad Small Form Factor Pluggable-Double Density) form factor maximizes port density while minimizing power consumption, making it ideal for space-constrained environments. Eight individual channels deliver the aggregate 400GB throughput, enabling efficient parallel data transmission. Connectivity and Compatibility: Features industry-standard MTP/MPO-16/APC connectors that ensure seamless integration with existing multimode fiber infrastructure. Direct compatibility with Dell systems (407-BCHW/407-BCIC) eliminates compatibility concerns. Custom brand programming is available for enterprise deployments requiring specific identifiers. Quality and Compliance: Constructed with a durable metal case and advanced laser transmitter technology, this transceiver undergoes rigorous testing to IEEE 802.3cm and QSFP-DD MSA specifications. It holds Class 1 Laser certification and meets stringent compliance standards including EU RoHS Directive 2002/95/EC, UL, TUV, and FDA 21CFR 1040.10. The 90-day limited warranty provides peace of mind. Ideal Applications: Perfect for high-speed interconnects between data center switches, storage arrays, and network aggregation points. Supports cloud infrastructure, enterprise data centers, and HPC environments where multimode fiber deployments are prevalent. The 100m reach over OM4 covers typical intra-building distances while maintaining 400GB throughput. Reliable Performance: With operating temperatures from 0-70°C, this transceiver maintains consistent performance across diverse installation environments. Free standard shipping on orders over $99, with rapid availability from Danville, CA and Beaufort, SC locations ensures quick deployment.
