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.
This network solution utilizes NADDOD optical modules to connect the products and achieve a network architecture upgrade from 100G to 400G. It provides higher data transmission rates and increased reliability while effectively reducing network latency between Spine switches and Leaf switches.
NADDOD 400G optical transceiver has great advantages in increasing data throughput and maximizing data center bandwidth and port density. 400G QSFP-DD has been tested and recognized by the global market as we are the first brand to complete the commercial order delivery of 400G data center optical modules.
NADDOD has a full range of professional testing equipments for testing various parameters of products to ensure high performance and quality of optical transmission stability.
