Cisco HCO-ADPT-OPT-SIA HCO Third-Party Optical Adapter

Add a third-party optical adapter at the HCO optical connection point when an installation calls for the SIA-designated adapter. Cisco HCO-ADPT-OPT-SIA is an accessory rather than an independent network appliance. Its role is to provide the adapter element in an optical interface path, supporting deployments that require a separately identified third-party optical connection component. Adapter selection matters where the physical optical interface must align with the installed HCO equipment and the intended third-party connection. This item is specifically designated for an optical adapter application; it should not be treated as an optical module, patch cable, switch port, or standalone conversion device. The ordering code identifies the SIA variant, helping distinguish this adapter requirement from other HCO hardware elements. Use this accessory where the deployment design explicitly calls for a third-party optical adapter with the SIA designation. Verify the required host-side interface, optical media type, connector format, and any associated components against the installed equipment before installation. Those interface details determine whether the adapter fits the intended optical path. The product’s distinguishing characteristics are its HCO association, third-party optical adapter purpose, and SIA designation.
