ISO 45001:2018
ISO 9001:2015
The 400GBASE-ER4L module, Duplex LC connector, up to 30km over parallel single-mode fiber with 400G KP4 FEC. It is compliant to IEEE 802.3bs protocol and 400GAUI-8, QSFP-DD MSA. The module converts 8 channels of 50Gb/s (PAM4) electrical input data into four LAN-WDM optical signals, multiplexed into one channel for 400Gb/s optical transmission. The 400 Gigabit Ethernet signal is carried over four LAN WDM wavelength grid wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device.It is suitable for Data Center, Enterprise networking.
