Description

Nokia QDDCO4Z0 Compatible 400GBASE DCO QSFP-DD DWDM Tunable Coherent ≤40km Unamplified DDM/DOM Duplex LC SMF Optical Transceiver ModuleDescription NADDOD Nokia QDDCO4Z0 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

NADDOD Cisco QDD-400G-DR4-S compatible 400G QSFP-DD DR4 optical module adopts a 1310 nm EML transmitter and PAM4 pulse amplitude modulation

delivering an aggregate transmission capacity of 800Gb/s by integrating two independent 400G DR4 channels

This module features a Quad Small Form-Factor Pluggable – Double Density (QSFP-DD) form factor with 4 CWDM4 lanes and 4-level Pulse Amplitude Modulation (PAM4) encoding

NADDOD NVIDIA/Mellanox QDD-400G-ER4 Compatible 400G QSFP-DD ER4 is a 400Gb/s QSFP-DD optical transceiver module designed for long-haul transmission

By combining dual-channel LR4 architecture with robust environmental tolerance to temperature

it features Type B polarity and a 3

high-bandwidth interconnects in modern data centers

2ft) 200GBASE QSFP56 to QSFP56 direct attach copper cable (DAC cable) for QM8700/QM8790

and uses 100G-PAM4 modulation to enable short-reach transmission of up to 50 meters over multimode fiber

When linked to 1:2 splitter fiber cable split end has only 2 channels and will activate only 2-channels in the 400G transceiver automatically creating a 200G speed and reducing power

The NVIDIA/Mellanox MFP7E20-N020 compatible 20m breakout cable delivers reliable OM4 performance

making it suitable for scalable 800G switching
