The JBX02297 1000BASE-ZX SFP transceiver module represents a premium solution for organizations requiring extended-range gigabit Ethernet connectivity over singlemode fiber infrastructure. With a transmission distance capability of 70 kilometers, this module significantly extends network reach compared to standard multimode transceivers, making it ideal for campus interconnects, metro-area networks, and long-haul telecommunications applications. **Key Technical Features:** This transceiver operates at 1550nm wavelength and delivers 1GB data rates with full duplex capability. The 9/125 singlemode fiber core specification ensures compatibility with standard carrier-grade infrastructure. The duplex LC/UPC connectors provide secure, low-insertion-loss connections critical for maintaining signal integrity over extended distances. **Compatibility & Integration:** The module is a direct compatible replacement for Cisco SFP-GE-Z and GLC-ZX-SMD models, eliminating costly proprietary vendor lock-in. IEEE 802.3z and SFF-8472 standard compliance guarantees interoperability across mixed-vendor network environments. **Safety & Compliance:** Comprehensive certifications include Class 1 Laser safety, UL/FDA approval (21CFR 1040.10), and TUV validation. RoHS and EU directive 2002/95/EC compliance ensures hazardous substance elimination. The metal case construction provides electromagnetic shielding and enhanced durability in demanding environments. **Operating Conditions:** Durable performance across -10 to 85°C (-14 to 185°F) temperature ranges makes this module suitable for controlled data center environments and outdoor fiber enclosures. Custom brand programming is available for OEM and white-label applications. **Support & Warranty:** Backed by a 90-day limited warranty and free standard shipping on orders exceeding $99, this cost-effective solution ships from U.S. locations (Danville, CA and Beaufort, SC) for rapid deployment.
