400G QSFP-DD High-Tx Power coherent optics Metro / regional DCI, Duplex LC Module, SSM, Compatible Transceiver

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.

We ran an extended burn-in test before deployment. The temperature, Tx power, and Rx power stayed stable throughout the test window.

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 used this for a metro interconnect and saw clean DOM readings after turn-up. The link has been stable during peak traffic.

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