NVIDIA MCA7J75 800Gb/s OSFP to 4×200Gb/s QSFP112 Active Copper Splitter Cable - 4 m/5 m, High-Speed Data Center Connectivity

NVIDIA MCA7J75 is an 800 Gb/s twin-port OSFP to 4×200 Gb/s QSFP112 Active Copper Cable (ACC) splitter, designed for high-density data center environments and InfiniBand NDR networks. It provides ultra-fast, low-latency connectivity between OSFP switches and QSFP112 devices, enabling scalable, high-performance networking. Featuring integrated equalizer ICs, the MCA7J75 maintains signal integrity over 4 m (30 AWG) and 5 m (26 AWG) copper links with low power consumption (1.5 W for OSFP, 0.3–0.6 W per QSFP112 tail). 

Its robust, hot-pluggable design supports reliable, high-bandwidth server interconnects for GPUs, DPUs, and NICs, while adhering to industry standards for durability and compatibility, including LSZH jacket for fire safety and low-smoke environments. The cable also supports NVIDIA ConnectX‑7 NICs, BlueField‑3 DPUs, and OSFP switches, ensuring seamless integration in modern data centers. Its low-latency performance ensures minimal signal degradation for critical workloads, while its flexible AWG options provide easy installation in dense racks.

TECHNICAL SPECIFICATIONS:

HARDWARE:

MCA7J75 features a twin-port OSFP connector on one end and four QSFP112 connectors on the other, providing a compact, high-density breakout design for modern data centers. Each connector includes robust metal housings with heat-sink fins, ensuring stable performance under continuous operation. The cable is hot-pluggable, allowing easy installation or replacement without disrupting network uptime.

Two cable variants are available to provide flexible deployment options: a 4 m cable using 30 AWG wire for standard rack-to-rack connections, and a 5 m cable using 26 AWG wire for longer reach without signal degradation. Both cables feature integrated equalizer ICs for extended reach and low-latency performance.
