The JBX01466 100GBASE-LR4 QSFP28 transceiver represents a cutting-edge solution for organizations requiring high-capacity, long-reach optical connectivity. Engineered to IEEE 802.3bm and QSFP28 MSA specifications, this module delivers 100 gigabits per second of throughput across distances up to 10 kilometers over standard singlemode fiber infrastructure. **Technical Specifications:** This dual-fiber transceiver features a compact QSFP28 form factor with dimensions of 5x4x2 inches and includes duplex LC/UPC connectors for reliable signal transmission. The module utilizes 9/125 micrometer singlemode fiber, the industry standard for long-distance applications, and operates reliably from 0 to 70°C, accommodating diverse environmental conditions. **Compatibility & Integration:** Designed as a direct replacement for the Juniper JNP-QSFP-100G-LR4, this transceiver seamlessly integrates into existing Juniper network infrastructure. It also serves as compatible replacement for multiple OEM part numbers including QSFP-100GBASE-LR4, QSFP-100G-LR4-T2, QSFP-100G-LR4-2, and QSFP-100G-LR4-C variants, providing flexibility for legacy system upgrades. **Quality & Compliance:** Manufactured with a metal case and precision laser transmitter components, the module meets stringent RoHS/ELV directives per EU 2002/95/EC. Comprehensive safety certifications including Class 1 Laser compliance, TUV, UL, and FDA 21CFR 1040.10 ensure safe operation in professional environments. Custom brand programming is available for OEM customers requiring specific firmware configurations. **Deployment & Support:** Ships from Danville, CA and Beaufort, SC locations with complimentary standard shipping on orders exceeding $99. Each module includes a 90-day limited warranty, and the product classification (HS Code 8544.70.0000) facilitates streamlined international procurement. Perfect for data center upgrades, long-distance backbone expansion, and high-performance network architecture implementations.
