The AddOn MSA and TAA Compliant 10GBASE-XGS SFP+ Transceiver is a specialized Optical Network Unit (ONU) module engineered for next-generation XGS-PON fiber networks. This advanced transceiver delivers symmetrical 10 Gbps upload and download speeds over single-mode fiber, utilizing 1270nm TX and 1577nm RX wavelengths with a simplex SC connector for point-to-multipoint architecture. Designed for distances up to 20km (12.4 miles), this module transforms a standard SFP+ switch port into a fully functional fiber ONT/ONU with built-in MAC capability. The ruggedized industrial design operates reliably in extreme temperatures from -40°F to 185°F (-40°C to 85°C), making it ideal for outdoor deployments, utility networks, and harsh environmental conditions. As a TAA Compliant product, this transceiver meets strict procurement standards for U.S. Federal Government and Department of Defense projects. MSA compliance ensures seamless integration with any MSA-compliant switch or router. Features include Digital Optical Monitoring (DOM) support for real-time performance diagnostics, enabling network administrators to monitor optical power levels and system health proactively.
