Keep critical network paths open across long distances with this AddOn 10GBASE-ZR SFP+ transceiver. Built for Avaya/Nortel compatibility and TAA-compliant procurement requirements, it supports 10 Gigabit Ethernet over single-mode fiber through an LC connector. That makes it a practical choice for infrastructure teams that need to extend links without moving to a more expensive transport layer. The ZR optical profile is designed for long-reach deployments where standard short-range optics fall short. Use it to connect buildings, aggregation points, and remote network rooms while preserving the 10 GbE throughput your applications expect. The single-mode design helps maintain signal integrity over extended distances, and the lifetime warranty adds confidence for environments that value predictable support over commodity pricing. For teams managing regulated purchasing, mixed-vendor environments, or legacy Avaya/Nortel infrastructure, this module offers a clean path to keep existing optics plans aligned with compliance and distance requirements.
