Keep critical 10 GbE links alive across extended distances with this compatible AVAYA/NORTEL transceiver from AddOn Networks. Built for optical network and data networking applications, it supports 10GBase-ZR operation over single-mode fiber and is designed for environments where longer reach is more important than short-range density. The module operates at 1550.12 nm and is specified for up to 80 km of reach, making it a strong fit for campus interconnects, metro aggregation, and remote equipment links that need stable transport over long fiber runs. Its LC duplex interface aligns with common single-mode deployments, while the compatible design helps preserve OEM-level form, fit, and function without paying OEM pricing. For teams standardizing on proven optics, this transceiver offers a practical way to expand capacity while keeping procurement predictable. It is a focused choice for infrastructure groups that need dependable long-distance 10 Gigabit Ethernet connectivity and want a compatible part that fits into established AVAYA/NORTEL-based environments.
