The JBX02035 1000BASE-T SFP transceiver is a high-performance networking component designed to extend your Gigabit Ethernet connectivity using existing copper infrastructure. This module provides an economical solution for organizations seeking to leverage RJ45 cabling without upgrading to fiber optic systems, making it particularly valuable in data centers, enterprise networks, and telecommunications environments. **Key Technical Features:** This transceiver operates at 1GB data rates over standard Category 5e/6 copper cabling up to 100 meters. Built to IEEE 802.3z and SFF-8472 specifications, it ensures interoperability across compatible networking equipment. The SFP (Small Form-Factor Pluggable) design allows flexible deployment in slot-constrained environments, with dimensions of 5 x 4 x 2 inches and metal construction providing robust protection. **Compatibility & Integration:** Tested and qualified for NVIDIA Mellanox infrastructure, this module directly replaces the OEM part 980-9I251-00IS00. Its standardized RJ45 connector eliminates proprietary cabling requirements, reducing total cost of ownership while enabling straightforward installation and troubleshooting. **Reliability & Compliance:** Operating across -10 to 85°C, the JBX02035 maintains performance in diverse environmental conditions. Full RoHS/ELV compliance and TUV/UL certifications guarantee regulatory adherence for EU, North American, and international deployments. A 90-day limited warranty provides purchase confidence. **Ideal Applications:** Perfect for network expansion, equipment replacement, and infrastructure modernization projects. The transceiver suits edge computing, remote locations, and retrofit scenarios where fiber installation proves impractical or cost-prohibitive. Custom brand programming options support OEM integrators and white-label resellers. **Logistics & Support:** Shipped from multiple US locations (Danville, CA and Beaufort, SC), this module qualifies for free standard shipping on orders exceeding $99, ensuring rapid deployment for time-sensitive projects.
