The JBX01497 100GBASE-ZR4 QSFP28 transceiver represents a cost-effective solution for organizations requiring high-capacity, long-distance optical connectivity. This module delivers 100 gigabits per second of bandwidth over distances up to 80 kilometers on standard singlemode fiber infrastructure, eliminating the need for expensive optical amplification systems in many deployment scenarios. **Technical Excellence** This transceiver adheres to IEEE 802.3bm specifications and QSFP28 Multi-Source Agreement (MSA) standards, ensuring compatibility across diverse networking environments. The forward error correction (FEC) technology enhances signal integrity and reliability, particularly valuable in challenging fiber plant conditions. With its 9/125 micron singlemode fiber compatibility, the module integrates seamlessly with existing campus and metro network infrastructure. **Superior Connectivity** The Duplex LC/UPC connector design provides industry-standard optical termination, ensuring minimal insertion loss and return loss for optimal signal quality. The metal case construction with integrated laser transmitter offers durability and reliable performance in demanding rack environments. **Safety and Compliance** Fully certified to Class 1 Laser standards (LN #50 7/2001) and compliant with TUV, UL/FDA (21CFR 1040.10) requirements, this transceiver meets rigorous safety specifications. RoHS and ELV directive compliance (EU 2002/95/EC) demonstrates environmental responsibility and adherence to global manufacturing standards. **Juniper Compatibility** Perfect for Juniper-based networks, this module directly replaces OEM part numbers JNP-QSFP-100G-ZR4, QSFP-100G-ZR4, and QSFP-100G-ZR4L, simplifying procurement and deployment processes. Custom brand programming is available for organizations requiring vendor-specific configurations. **Operational Specifications** Designed for robust performance across a 0-70°C operating range, this transceiver handles diverse environmental conditions. The compact 5x4x2 inch form factor fits standard QSFP28 slots without modification. Manufactured in Vietnam and China using quality-controlled processes, the module undergoes rigorous testing before shipment. **Reliability and Support** Backed by a 90-day limited warranty and available with free standard shipping on orders exceeding $99, this transceiver provides exceptional value. Ships from strategically located US facilities (Danville, CA and Beaufort, SC) for expedited delivery. Ideal applications include data center campus interconnects, metropolitan area networks, disaster recovery links, and enterprise backbone upgrades requiring 100GB capacity without traditional DWDM complexity.
