Arista 400GBASE-XDR4 Compatible 400G QSFP-DD XDR4 PAM4 LWDM4 Optical Transceiver Module (MUX/DEMUX design SMF MTP/MPO-12 2km DDM with FEC)

The Arista 400GBASE-XDR4 Module supports 100G breakout link lengths of up to 2km with FEC performed on the host platform. This 400GBase-DR4+ QSFP-DD transceiver has four pairs of single-mode fiber (SMF) with an MPO-12 connector. It's designed for 400 Gigabit Ethernet (GbE) and can be used as 4x100G breakout to QSFP28 100G-DR (up to 500m), 100G-FR, and 100G-LR. NADDOD offers Arista 400GBASE-XDR4 Compatible 400G QSFP-DD XDR4 (DR4+) Optical module, which adopts a 1310nm EML transmitter type and PAM4 pulse amplitude modulation mode, using a nominal wavelength of 1310 nm for 400Gb/s optical transmission. It is compliant to the IEEE 802.3cu for 100GBASE- FR1, and 400GAUI-8/CEI-56G-VSR-PAM4 standards. It is widely used in high-performance computing (HPC) networks, data centers, 400G Ethernet interconnect, enterprise core, and distribution layers, and service provider applications.
