Description

Arista QDD-400G-ZR Compatible 400GBASE DCO QSFP-DD DWDM Tunable Coherent ≤40km Unamplified DDM/DOM Duplex LC SMF Optical Transceiver ModuleDescription NADDOD Arista QDD 400G ZR Compatible QSFP DD 400G ZR is a C band, frequency tunable coherent optical transceiver. It integrates a 7 nm coherent DSP ASIC with best in class ultra narrow linewidth tunable lasers, high speed modulators, and high responsivity coherent receivers to deliver high performance using 400G DP 16QAM modulation. The module is designed for 400G DWDM data center interconnect (DCI) applications, supporting up to 40 km

It is designed for use in 200Gb/s InfiniBand HDR systems or 200G Ethernet netwoking

the QDD-800G-2xDR4 supports flexible connectivity to either a native 800G optical module or two 400G DR4 QSFP-DD modules using MPO-12 APC fiber cabling

41 Compatible is a 25GBASE-DW10 SFP28 module operating on DWDM Channel 20 for 10km single-mode fiber links

35dB maximum insertion loss

This RJ45 assembly ensures reliable Gigabit performance for top-of-rack server and switch interconnections

each 400G channel implements 4×100G PAM4 transmission over an MPO-12 interface

The high-quality Ultra Physical Contact connectors ensure that the intense fresh finish is perfectly preserved from the core to your workstation

Cisco QDD-400-CU1M Compatible is a 1-meter 400G QSFP-DD passive DAC twinax cable designed for short-range high-speed interconnects in Cisco environments

The durable design ensures stable connectivity for top-of-rack switch interconnections in professional data centers via QSFP+ ports

it supports a reach of 100m on OM4 using existing LC cabling

The NVIDIA/Mellanox compatible 2m passive direct attach copper cable provides a high-performance 400G link for interconnecting OSFP Flat Top and QSFP-DD interfaces

This assembly is perfect for AI and high-performance computing environments where rapid expansion using legacy fiber is required
