The JBX01909 10GBASE-ZR SFP+ transceiver represents enterprise-grade optical networking technology designed for mission-critical applications requiring extended transmission distances. This sophisticated module operates at the 1550nm wavelength band, enabling reliable 10 gigabit-per-second data transmission across distances reaching 80 kilometers over standard single-mode fiber infrastructure. **Core Technical Specifications:** This SFP+ transceiver module complies with IEEE 802.3ae and SFF specifications (SFF-8431, SFF-8472), ensuring compatibility with industry-standard optical networks. The duplex LC/UPC connector provides a reliable, low-loss connection interface suitable for professional data center environments. Operating temperature range from 0 to 70°C (32 to 158°F) accommodates diverse climate-controlled facility requirements. **Compatibility and Integration:** Designed as a direct replacement for Juniper's QFX-SFP-10GE-ZR module, the JBX01909 integrates seamlessly into existing Juniper QFX switching infrastructure without requiring firmware updates or reconfiguration. This plug-and-play compatibility significantly reduces deployment time and minimizes network downtime. **Superior Build Quality:** Constructed with a durable metal case housing precision laser transmitter technology, this transceiver delivers consistent performance in demanding networking environments. The robust design withstands repeated insertions and provides electromagnetic shielding for reliable operation alongside other network equipment. **Compliance and Certification:** Fully RoHS/ELV compliant and conforming to EU Directive 2002/95/EC, this module meets stringent environmental and safety standards. Class 1 laser certification (per FDA 21CFR 1040.10 and TUV standards) confirms safe operation for personnel and network infrastructure. **Ideal Applications:** Perfect for metropolitan area networks (MANs), campus interconnects, disaster recovery links, and high-performance data center architectures requiring extended reach without signal regeneration. The 80km range eliminates need for expensive amplification equipment in many deployment scenarios. **Value and Support:** Including 90-day limited warranty and custom brand programming capabilities, this transceiver provides exceptional value for organizations standardizing on Juniper platforms. Free standard shipping on orders exceeding $99 enhances overall acquisition cost benefits.
