400G QSFP-DD DP-16QAM / DP-QPSK 1,000km - 1,500km, Duplex LC Module, SSM, Compatible Transceiver

For our 400G QSFP-DD 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.

The mechanical fit is firm and the link did not flap during vibration checks. This is suitable for field networks where consumer-grade optics are risky.

For our 400G QSFP-DD requirement, we ran an extended burn-in test before deployment. The temperature, Tx power, and Rx power stayed stable throughout the test window.

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.

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