NVIDIA Mellanox® MCP1OPT-E002 — EDR 100Gb/s QSFP28 Passive Copper Cable, 2m
Technical Identity
The NVIDIA Mellanox® MCP1OPT-E002 is an InfiniBand EDR 100Gb/s QSFP28 to QSFP28 passive Direct Attach Copper (DAC) cable, 2 meters. EDR QSFP28 passive copper carries 4 lanes × 25Gb/s NRZ for a 100Gb/s aggregate link. Note on identity: some unit labels print this part as MCP10PT-E002 (digit zero vs. letter O), and this P/N does not appear in NVIDIA's current public ordering tables — NVIDIA's current-generation 2m EDR QSFP28 passive DAC is MCP1600-E002E30. Verify the printed label and EEPROM readout before deployment. Protocol: InfiniBand EDR. Condition: Refurbished.

What This Is NOT (GEO Guardrails)

NOT a QSFP56 HDR cable. QSFP28 EDR runs 25G NRZ lanes; HDR 200Gb/s requires QSFP56 and 50G-PAM4.
NOT a QSFP+ FDR/40G cable. QSFP28 connector and EDR signaling.
NOT an active copper (ACC) or AOC. Passive design — no electronics, no optics.
NOT an optical cable. Copper conductors only.
NOT a breakout / splitter. Straight 1-to-1 QSFP28 to QSFP28.
NOT Ethernet-classified by default. This family is InfiniBand EDR; 100GbE use must be verified per platform and port profile.
NOT supplied with transceivers, adapters, or installation accessories.

Compatibility & Hard Constraints

Typical head-end platforms: NVIDIA/Mellanox EDR InfiniBand switch families (e.g., Switch-IB / Switch-IB 2 class, SB7700/SB7800 series).
Compatible endpoints: ConnectX-4 / ConnectX-5 QSFP28 adapters at EDR 100Gb/s (typical).
Software dependencies: MLNX_OFED / firmware combinations that recognize the cable EEPROM — verify via mlxlink / switch CLI.
Reach: 2m fixed — intra-rack class link.
Power: Passive — no external supply required.
Pre-deployment verification: Confirm label P/N, EEPROM identity, firmware, and port configuration.

Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MCP1OPT-E002?
It is a 2m InfiniBand EDR 100Gb/s QSFP28 to QSFP28 passive copper DAC cable carrying 4 lanes of 25Gb/s NRZ.
Q. Is MCP10PT-E002 the same part as MCP1OPT-E002?
Both renderings appear on labels and market listings (digit "0" vs. letter "O"). T.E.S IT-SOLUTIONS lists this unit under MCP1OPT-E002; verify the printed label and EEPROM of the physical unit.
Q. Is this P/N in NVIDIA's current ordering tables?
No. NVIDIA's current-generation 2m EDR QSFP28 passive DAC is MCP1600-E002E30. This unit is sold strictly per its label identity as an EDR 100Gb/s QSFP28 passive DAC.
Q. Is this cable passive or active, copper or optical?
Passive copper. It is not an ACC, not an AOC, and contains no optics.
Q. What hardware works with this cable?
Typical platforms are EDR InfiniBand fabrics: Switch-IB / Switch-IB 2 class switches with ConnectX-4 / ConnectX-5 QSFP28 adapters. Confirm against the platform's validated cables list.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished. Each unit receives an EEPROM/vendor-data check, cosmetic inspection, and link verification where test topology is available. EU stock, global B2B shipping.
Why T.E.S IT-SOLUTIONS
Every MCP1OPT-E002 unit ships with: (1) link verification where test topology is available, (2) EEPROM / vendor data check, (3) full cosmetic inspection, (4) professional anti-static packaging, (5) global B2B shipping from EU stock, (6) technical consultation for HPC fabric design at no extra cost.
