400G QSFP-DD SerDes 深度調校高速兼容 DR / FR / LR 可選, Duplex LC Module, SSM, Compatible Transceiver

For our 400G QSFP-DD requirement, this was a direct replacement in our existing environment. No special tuning was required and the port came up at the expected speed.

Performance matches the advertised specification and the price is much better than OEM optics. Support was responsive when we asked for compatibility confirmation.

The industrial temperature rating gives us more confidence for outdoor and cabinet deployments. The module stayed stable during temperature variation.

For our 400G QSFP-DD requirement, 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.

The order arrived quickly, well packed, and ready for installation. We had no damaged units and the rollout schedule was not delayed.
