No, you cannot plug an OSFP module into a QSFP-DD port, or a QSFP-DD module into an OSFP port. The OSFP and QSFP-DD form-factors are not physically compatible with each other. The OSFP is slightly wider and deeper than the QSFP-DD, and has a different electrical interface and connector. The OSFP also has a higher power consumption and heat dissipation than the QSFP-DD. Therefore, you need to use the appropriate form-factor for your port and device.
However, both OSFP and QSFP-DD are backward compatible with QSFP+/QSFP28 modules, which are widely used for 100G applications. You can use an adapter to plug a QSFP+/QSFP28 module into an OSFP or QSFP-DD port, and it will work as expected. This provides flexibility and interoperability for network operators who want to upgrade their infrastructure to 400G.

AEC Active Cable Testing Solution – Deciphering AEC Performance Step by Step
With the continuous expansion of data centers and the increasing demand for high-performance computing, the AEC (Active Electrical Cable) has emerged as an effective high-speed, short-distance transmission solution. Major cloud service providers—such as Google, AWS, and Microsoft—have already embarked on large-scale deployments of AEC, while hardware manufacturers like Nvidia have
Why Do 400G/100G Optical Ports in Switches Require Forward Error Correction (FEC)?
Introduction Optical networks require the use of Forward Error Correction (FEC) to guarantee reliable communication. Similar to how a reader may overlook a single spelling mistake in a text but struggle when errors accumulate, digital transmissions—encoded as sequences of “0”s and “1”s—are subject to inevitable signal attenuation and bit errors.
