The Short Reach 4-channel (SR4) design uses 100G-PAM4 modulation and has a maximum fiber reach of 50-meters using OM4 multimode fiber and assumes two optical patch panels in the link
It is specifically optimized for high-performance NVIDIA/Mellanox switching fabrics requiring precise 400G-to-100G port mapping
NADDOD Ciena 180-3530-900 Compatible QSFP-DD 400G ZR is a C-band
6ft) 200GBASE QSFP56 to QSFP56 direct attach copper cable (DAC cable) for QM8700/QM8790
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
Juniper Compatible ACC 1.1m (3ft) Twin-port 2x800Gb/s OSFP224 RHS/Flat Top to Twin-port 2x800Gb/s OSFP224 RHS/Flat Top Active Copper Cable for Liquid-Cooled QFX5250 Series Switch Active Copper Cables The Short Reach 4-channel (SR4)Description NADDOD OSFP 1. 6T AC11F is a 1. 1m (3ft) 1. 6Tb s twin port OSFP Active Copper Cable (ACC), fully compatible with Juniper and supporting and high speed Ethernet protocols, featuring RHS flat top OSFP connectors on both ends. The cable integrates 8200Gb s PAM4 electrical lanes, delivering an aggregate bandwidth of 1. 6Tb s for short reach, high speed interconnects. Designed with a simple, low component architecture, ACC cables provide ultra
