400GBASE-FR4 QSFP-DD PAM4 1310nm 2km DOM Optical Transceiver Module (SMF, 1310nm, 2km, LC, DOM)
The 400GBASE-FR4 module supports link lengths of up to 2km SMF with duplex LC connector. It is compliant to IEEE 802.3bs, 400GBASE-FR4 Spec of 100G Lambda MSA group, and 400GAUI-8/CEI-56G-VSR-PAM4 standards. The 400 Gigabit Ethernet signal is carried over four CWDM grid optical wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device.
