NVIDIA QSFP56 to 2xQSFP56 Active Optical Splitter Cable

Overview

The NVIDIA MFS1S50-H005V is an active optical splitter cable that converts a single 200Gb/s HDR InfiniBand connection into two separate 100Gb/s HDR100 links. It uses advanced 4-channel 50Gb/s PAM4 modulation to maintain high-speed data transfer while efficiently splitting the signal. Designed for data centers and high-performance computing environments, this cable supports hot-pluggable operation and offers an active optical reach of up to 30 meters, making it suitable for medium-range connections without compromising reliability or speed.
