Lenovo 10M HDR-2XHDR100 Splitter OPT CBL - 4Z57A72563

Lenovo 4Z57A72563 10m HDR-2XHDR100 Splitter Cable

Overview

The Lenovo 4Z57A72563 is a 10-meter optical splitter cable designed to break out a single HDR InfiniBand port into two HDR100 connections. This cable is critical for high-performance computing (HPC) and data center environments where maximizing network port utilization and bandwidth is paramount. It allows a single 200Gbps HDR port to drive two 100Gbps HDR100 links, ideal for expanding connectivity to servers or network switches without requiring additional network interface cards (NICs).

Compatibility

This splitter cable is specifically designed for Mellanox HDR InfiniBand solutions. It is compatible with servers and network devices utilizing Mellanox ConnectX-6 Dx adapters and other HDR InfiniBand host channel adapters (HCAs) that support QSFP56 breakout configurations. The cable connects from a single QSFP56 HDR IB port on the source device to two QSFP56 HDR100 ports on the target devices.

Installation Notes

The cable utilizes optical QSFP56 connectors on both ends. The primary connector plugs into the single HDR IB port, while the two breakout connectors attach to the target HDR100 ports. Ensure proper alignment and secure connection of all QSFP56 connectors. The cable is rated for 100Gbps per lane and requires appropriate fiber optic cleanliness and handling practices typical for high-speed optical interconnects. The 10-meter length provides significant reach for rack-to-rack or within-rack connectivity.
