40G QSFP+ 1310nm CWDM, industrial durable design 40km, Duplex LC Module, SSM, Compatible Transceiver

For our 40G QSFP+ requirement, the order arrived quickly, well packed, and ready for installation. We had no damaged units and the rollout schedule was not delayed.

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.

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