Preserve high-density fiber links with a transceiver built for DWDM environments that demand tight wavelength control and procurement-ready compliance. The AddOn Networks 1018-7701-AO is a TAA-compliant 1,000BASE-DWDM SFP designed for compatibility with Optelian 1018-7701 deployments and HPE-aligned infrastructure requirements. Its 100 GHz channel spacing supports dense optical planning where spectrum efficiency matters and rack space is already committed. For teams standardizing on vendor-compatible optics, this module helps maintain link continuity without forcing a broader platform refresh. That matters when the cost of a single port is measured against the operational impact of an outage or a delayed rollout. Use it where precise DWDM transport, controlled procurement, and predictable interoperability are part of the design brief. AddOn’s compatibility-focused approach gives infrastructure teams a practical alternative to OEM-only sourcing while keeping the deployment path clear for enterprise fiber environments.
