400G QSFP-DD Sealed active optical cable Intra-cabinet / adjacent cabinet, Duplex LC Module, SSM, Compatible Transceiver

For our 400G QSFP-DD requirement, performance matches the advertised specification and the price is much better than OEM optics. Support was responsive when we asked for compatibility confirmation.

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.

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

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 build quality feels solid and the module was recognized immediately by our switching platform. Goilips packaging and labeling also made inventory handling straightforward.
