Maintain dependable Gigabit Ethernet connectivity across extended fiber spans with this AddOn Networks SFP transceiver. Built as a compatible replacement for the ALCATEL 3HE00028CA-I, it is designed for environments where link stability, procurement compliance, and optical reach are non-negotiable. This module uses LC duplex connectivity and 1,553.33 nm DWDM optics to support long-haul transport over single-mode fiber. The 80 km reach makes it a practical fit for metro aggregation, inter-building links, and remote site connectivity where copper or short-reach optics fall short. As a TAA-compliant part, it also aligns with public sector and regulated procurement requirements. For infrastructure teams standardizing on proven optics, this transceiver offers a straightforward way to extend network capacity without changing the underlying platform. It is the kind of component that earns its place in the rack by preserving uptime, simplifying sourcing, and matching the optical profile required for demanding deployments.
