Lenovo 15M HDR-2XHDR100 Splitter OPT CBL - 4Z57A72564

Lenovo 4Z57A72564 15m HDR-2XHDR100 Splitter Cable

Overview

The Lenovo 4Z57A72564 is a 15-meter optical splitter cable designed to break out a single HDR IB (InfiniBand) or 100GbE QSFP56 port into two HDR100 ports. This cable is crucial for extending high-speed network connectivity from servers equipped with Mellanox ConnectX-6 Dx adapters, enabling flexible deployment of high-performance computing and storage solutions where direct port access is limited.

Compatibility

This splitter cable is specifically designed for use with Mellanox HDR InfiniBand or 100GbE interfaces that support QSFP56 breakout configurations. It is compatible with Lenovo ThinkSystem servers and networking components featuring Mellanox ConnectX-6 Dx adapters, such as the MCX623106AS-CDAT (PCIe) and MCX623436AN-CDAB (OCP) Ethernet adapters. Ensure your host adapter and connected devices support HDR IB or 100GbE QSFP56 signaling for proper operation.

Installation Notes

The cable utilizes QSFP56 connectors on one end (splitting into two HDR100 connectors on the other). Ensure the QSFP56 connector is fully seated into the host adapter port and the two HDR100 connectors are securely plugged into the target devices. The 15-meter length provides significant reach for rack-to-rack or within-rack connectivity. The optical nature of the cable requires clean handling and protection from sharp bends to maintain signal integrity.
