## Long description

The Lenovo 4Z57A14182 QSFP56 to QSFP56 Passive 200G Twinax Copper Blue is a passive direct attach cable designed for high-density network interconnects. With QSFP56 connectors on both ends and a 200 Gigabit aggregated throughput, this Twinax cable provides a short-reach, low-latency copper link suitable for top-of-rack and adjacent-rack connections in data centers and enterprise network racks. The cable is built to support modern 200G-capable switches and network adapters while offering a compact form factor and reliable electrical performance.
Advantages
This passive Twinax cable offers a cost-effective, power-efficient alternative to optical transceivers for short-distance connections, reducing overall deployment and operating costs. Its QSFP56 endpoints enable plug-and-play compatibility with equipment that supports 200G QSFP56 ports, providing stable bandwidth and low signal latency. The cable’s construction minimizes signal loss over short runs and simplifies rack cabling with a single-cable, high-throughput solution.
Suitable for
 Top-of-rack switch to switch connections within the same rack
 Interconnects between adjacent racks in data centers
 Direct links between 200G-capable network adapters and switches
 High-density server and storage networking in constrained spaces
Key specifications
 Connector type: QSFP56 to QSFP56
 Data rate: 200 Gbit/s (aggregate)
 Cable type: Passive Twinax copper
 Typical use case: Short-reach, rack-to-rack or within-rack connections
 Color: Blue
How to use
Insert each QSFP56 connector into the corresponding 200G-capable QSFP56 port on your switches or adapters until the latch engages. Ensure devices are powered off or follow hot-plug procedures recommended by your equipment vendor if connecting while live. Route the cable to avoid sharp bends and excessive strain; maintain the manufacturer’s minimum bend radius. Verify link status in the network equipment management interface to confirm a successful physical connection and proper speed negotiation.
Usage recommendations
Use this passive Twinax cable for short-distance, high-bandwidth connections where active optics are unnecessary. For runs beyond typical short-reach limits or where electrical interference is a concern, consider optical transceivers and fiber cabling as alternatives.
