Lenovo 20M HDR-2XHDR100 Splitter OPT CBL - 4Z57A72565

Lenovo 4Z57A72565 10m HDR IB to 2x HDR100 Splitter Cable

Overview

The Lenovo 4Z57A72565 is a 10-meter optical cable designed to split a single Mellanox HDR InfiniBand connection into two HDR100 connections. This cable is essential for high-performance computing and networking environments where you need to distribute a high-bandwidth signal from a single port to multiple endpoints, such as connecting a server to two network switches or storage devices.

Compatibility

This cable is specifically designed for Mellanox HDR InfiniBand infrastructure and is compatible with Mellanox ConnectX-6 Dx adapters (MCX623106AS-CDAT, MCX623436AN-CDAB) and other HDR IB devices requiring a QSFP56 splitter configuration. It facilitates the distribution of 200 Gbps HDR IB input into two 100 Gbps HDR100 outputs.

Installation Notes

Ensure clean connections for optical cables. The QSFP56 connectors are keyed to prevent incorrect insertion. For optimal performance and to avoid signal degradation, maintain the specified bend radius for the 10-meter OM3 multimode fiber. The cable is designed for a single port on a Mellanox adapter, splitting into two separate 100GbE connections.
