Jul 16, 2025 - FS 25G Optics-to-Optics Interoperability Matrix Interoperability FS transceivers and cables are based on industry standards and/or Multi-Source Agreements (MSA) and therefore interoperable with the relevant standards and MSA transceivers. Guidance on the interoperability of the FS 25G transceivers is detailed in Table 1. Table 1 shows the interoperability of 25G modules.
