Q: Can 400G NDR SR4 be interconnected with 800G Twin-Port NDR 2xSR4?
A: Yes, 800G Twin-Port NDR 2xSR4 with two OM4 MPO-12/APC patch cables can be connected to two 400G NDR SR4 optical modules.
Q: What is the difference between the OSFP package and common packages such as QSFP28?
A: OSFP is longer and wider than the traditionally used QSFP28/EDR or QSFP56/HDR formfactors.
Q: How is the modulation of the 400G NDR SR4 optical module?
A: 4 channels of 100G-PAM4 electrical and optical modulation.
