The JBX01901 10GBASE-ZR SFP+ transceiver represents a premium solution for organizations requiring high-speed, long-distance network connectivity. Delivering 10 Gigabit Ethernet transmission over distances up to 80 kilometers on single-mode fiber, this module is engineered for enterprise-grade reliability and performance. **Key Technical Specifications:** This 1550nm wavelength transceiver adheres to IEEE 802.3ae standards and SFF-8431/SFF-8472 specifications. It features duplex LC/UPC fiber connectors, ensuring secure and low-loss connections. The compact SFP+ form factor (5.0" L x 4.0" W x 2.0" H) fits standard transceiver slots without requiring external adapters. **Performance & Reliability:** Operating temperature range of 0°C to 70°C (32°F to 158°F) accommodates most data center and network closet environments. The metal case with integrated laser transmitter provides durability and longevity. RoHS and ELV directive compliance ensures environmental responsibility, while Class 1 Laser and TUV certifications guarantee safety. **Compatibility & Integration:** Direct compatibility with Extreme Networks 10310 switches and infrastructure makes deployment straightforward. The module replaces OEM part number 10310, reducing compatibility concerns and streamlining procurement processes. **Business Benefits:** The ZR designation indicates extended-range capability, making this module ideal for data center interconnects, campus backbone networks, and metropolitan area deployments. Compared to shorter-range transceivers, the 80km capability reduces the need for intermediate equipment and signal regeneration. **Quality Assurance:** Each unit includes a 90-day limited warranty. Custom brand programming is available, allowing organizations to standardize equipment across their infrastructure. Free standard shipping on orders over $99 and convenient shipping from multiple US locations (Danville, CA and Beaufort, SC) ensure fast delivery. **Deployment Considerations:** This module transmits low-voltage network signals and is manufactured in Vietnam and China under strict quality controls. It complements existing fiber infrastructure investments and provides cost-effective network expansion without requiring capital-intensive hardware upgrades. Ideal for IT managers and network engineers planning scalable, future-proof network architectures.
