Can I have an OSFP on One End of a 400G Link, and a QSFP-DD on the Other End?

Yes, you can have an OSFP on one end of a 400G link, and a QSFP-DD on the other end, as long as they are compatible with the same optical interface and modulation scheme. For example, you can use a 400G OSFP FR4 module on one end, and a 400G QSFP-DD FR4 module on the other end, since they both support 4x100G PAM4 over single-mode fibers. However, you will need an adapter to connect the OSFP module to the QSFP-DD cable, or vice versa. OSFP is as backward compatible with QSFP+/QSFP28 as QSFP-DD, but requires an additional OSFP to QSFP adapter. Since the OSFP is slightly wider and deeper than the QSFP, it is possible to build an adapter that supports existing 100G QSFP optics modules (QSFP28) in a OSFP cage.
