200G QSFP28 PAM4 / LAN-WDM, 4 wavelengths 10km, Duplex LC Module, SSM, Compatible Transceiver

For our 200G QSFP28 requirement, the build quality feels solid and the module was recognized immediately by our switching platform. Goilips packaging and labeling also made inventory handling straightforward.

We deployed this module in a live network and the link has remained stable under continuous traffic. The diagnostics are clear and the optical power margin is exactly where we expected it to be.

This was a direct replacement in our existing environment. No special tuning was required and the port came up at the expected speed.

For our 200G QSFP28 requirement, performance matches the advertised specification and the price is much better than OEM optics. Support was responsive when we asked for compatibility confirmation.

We added these to our spare parts pool because the compatibility and delivery lead time are predictable. Good option for planned expansion and emergency replacement.
