400G QSFP-DD No-DSP linear-drive optics Short reach, MTP/MPO Module, SSM, Compatible Transceiver

For our 400G QSFP-DD requirement, 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.

The module is a good fit for short-reach high-density links where latency and power matter. We saw stable links during cluster validation.

This was a direct replacement in our existing environment. No special tuning was required and the port came up at the expected speed.

For our 400G QSFP-DD requirement, the low-power design is helpful in dense racks. Thermal readings stayed controlled even with multiple adjacent ports populated.
