What’s the advantage of 400G Optical Transceiver Based on PAM4 Modulation
There are two common types of 400G transceiver packages: OSFP and QSFP-DD. OSFP-packaged optical transceivers have good thermal performance and can be scaled up to 800G, but they have a larger size. The optical transceivers in QSFP-DD packaging are simpler and more compatible. For 400G optical transceivers, both OSFP and QSFP-DD use the 8x50G/PAM4 electrical […]
