400G QSFP-DD LWDM4 40KM SFP Gigabit Ethernet Module Transceiver

Module Transceiver QSFP-DD QSFP 400G LWDM4 40KM SFP Gigabit Ethernet Switch

Module Transceiver QSFP 400G SFP Gigabit Ethernet Switch

400G QSFP-DD transceivers are defined by IEEE 802.3bs Ethernet standard and is an evolution of 100G QSFP28 transceivers. On 400G QSFP-DD 400G Ethernet is achieved with increased data throughput while maintaining the same bandwidth on per channel basis. This is due to 100G QSFP28 using NRZ (Non-Return-to-Zero) encoding and 400G QSFP-DD using PAM4 (Pulse Amplitude Modulation 4 levels) encoding. More on that in 100G Single Lambda (100G PAM & Single Lambda).
