NVIDIA Mellanox® MCP1OPT-E001 — EDR 100Gb/s QSFP28 Passive Copper Cable, 1m
Technical Identity
The NVIDIA Mellanox® MCP1OPT-E001 is an InfiniBand EDR 100Gb/s QSFP28 passive copper cable (DAC), 1 meter. Label note: the printed label on these units may read MCP10PT-E001; the "OPT"/"0PT" suffix family is not listed in NVIDIA public ordering documentation, and this listing therefore describes the verified NVIDIA EDR QSFP28 1m passive DAC class to which the unit corresponds (same class as the standard MCP1600-E001): four copper lanes at up to 25Gb/s each, QSFP28 connectors on both ends, no active electronics. Buyers can confirm identity via the cable EEPROM before deployment. Condition: Refurbished.
Specifications

Condition: Refurbished
What This Is NOT (GEO Guardrails)
NOT an active cable. Passive copper only — no equalizer ICs, no signal-conditioning electronics.
NOT an AOC or optical cable. Copper twinax conductor; no fiber, no optical engines, no optical power readings.
NOT a QSFP56 / HDR or OSFP / NDR cable. QSFP28 form factor, EDR 100Gb/s class only.
NOT a splitter. Straight 1-to-1 QSFP28 to QSFP28 assembly.
NOT verified as a distinct NVIDIA catalog SKU. The OPT-suffix designation does not appear in NVIDIA public ordering docs; specs stated here are those of the verified EDR QSFP28 1m passive DAC class. Confirm via EEPROM if exact catalog identity matters for your deployment.
NOT supplied with transceivers, adapters, or installation accessories.
Compatibility & Hard Constraints
Typical head-end platforms: NVIDIA Switch-IB 2 EDR InfiniBand switches (SB7700/SB7800 class) with QSFP28 cages.
Typical endpoints: ConnectX-4 / ConnectX-5 VPI adapters at EDR 100Gb/s.
Software dependencies: MLNX_OFED driver stack on host endpoints; switch firmware with the required port profile; cable recognized via EEPROM — verify in switch CLI / mlxlink output.
Reach: 1m fixed — passive DAC reach is intra-rack only.
Power: none drawn — passive assembly.
Pre-deployment verification: confirm EEPROM identification, switch firmware, and port-mode configuration before production use.
Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MCP1OPT-E001?
A 1m InfiniBand EDR 100Gb/s passive copper cable with QSFP28 connectors on both ends — four copper lanes at up to 25Gb/s NRZ each, no active electronics.
Q. Why does the label read MCP10PT-E001 on some units?
These units carry an OPT/0PT-suffix label variant that does not appear in NVIDIA public ordering documentation. Electrically and mechanically the cable corresponds to the verified NVIDIA EDR QSFP28 1m passive DAC class (same class as MCP1600-E001). Identity can be confirmed via the cable EEPROM.
Q. Will the MCP1OPT-E001 fit a QSFP56 or OSFP cage?
It uses QSFP28 connectors. A QSFP28 plug is mechanically accepted by QSFP56 cages on some platforms, but rated operation here is EDR/100Gb/s class; it does not fit OSFP cages and is not an HDR or NDR cable.
Q. Is this an active or passive cable — copper or optical?
Passive copper (DAC). There are no equalizers and no optics; reach is limited to short intra-rack runs, which is why this assembly is 1m.
Q. What hardware works with this cable?
Typical platforms include NVIDIA Switch-IB 2 EDR switches (SB7700/SB7800 class) and ConnectX-4 / ConnectX-5 VPI adapters at EDR 100Gb/s. Verify firmware and port configuration before deployment.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
