NVIDIA Mellanox MCP1OPT-W01Q30U2 Passive Copper HDR Test Cable, 200Gb/s, OSFP to 2x QSFP56, 1.9m: This enterprise networking cable is a 1.9-meter passive copper test cable with an OSFP connector on one end and two QSFP56 connectors on the other, part number MCP1OPT-W01Q30U2. It is designed for HDR InfiniBand testing and validation, breaking out a single 200Gb/s OSFP port to two 100Gb/s QSFP56 connections. As a passive cable, it requires no external power. This is a refurbished unit, tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MCP1OPT-W01Q30U2 is a breakout test cable that splits an OSFP 200Gb/s port into two QSFP56 HDR100 (100Gb/s each) connections. This cable is primarily used for testing and validation of HDR InfiniBand ports, loopback testing, and lab environments where OSFP-to-QSFP56 breakout connectivity is needed. The passive copper design at 1.9 meters keeps latency minimal and signal integrity high for test scenarios. Note: This is designated as a test cable and may not be intended for production deployment.
Deployment & Use Cases
HDR InfiniBand port validation and loopback testing in lab environments. OSFP-to-QSFP56 breakout verification for Quantum-2 switches and ConnectX-7 adapters. Pre-deployment cable plant validation for HDR InfiniBand fabrics. Network engineering labs testing OSFP breakout configurations before production rollout.
Technical Specifications

Compatibility & Hard Constraints
OSFP + QSFP56 Required: One end is OSFP, the other is 2x QSFP56. The OSFP end connects to switches or adapters with OSFP ports (e.g., Quantum-2). The QSFP56 ends connect to HDR100-capable devices. Test Cable Designation: This is primarily a test/validation cable. Confirm suitability for production use with your fabric design. HDR Speed Tier: Designed for HDR (200Gb/s breakout to 2x 100Gb/s). Not backward-compatible with EDR or FDR at native speeds. Passive Copper: 1.9m is well within passive copper specifications for HDR. For longer distances, active optical cables are required.
