NVIDIA Mellanox® 980-9IAMR-00X001 — MCA4K00-Family 1.6Tb/s OSFP to OSFP Active Copper Cable
Technical Identity
The NVIDIA 980-9IAMR-00X001 is a 1600Gb/s (1.6Tb/s) OSFP to OSFP Active Copper Cable (ACC) attributed to the NVIDIA MCA4K00 family. Per NVIDIA’s MCA4K00 product specification, this family runs 8 channels of 200G-PAM4 signaling in an OSFP RHS (Riding Heat Sink) to OSFP RHS configuration, and its cable firmware supports InfiniBand, Ethernet, and NVLink 5 (NVL5), automatically detected according to the protocol of the switch it attaches to. The exact OPN 980-9IAMR-00X001 does not appear in NVIDIA’s public ordering tables (which list 980-9IAM1/2/4-00X001 at 1.1m): the length, backshell and variant of the 9IAMR prefix must be verified against the unit label — do not interpolate from sibling OPNs. Condition: Refurbished.

Lane & Signal Logic

Each OSFP end: 8 electrical lanes × 200Gb/s PAM4 = 1600Gb/s aggregate, presented as 2× 800Gb/s twin-port channels.
Active electronics: integrated signal-conditioning circuitry in each connector maintains signal integrity over reaches beyond passive-DAC limits at 200G/lane.
EEPROM: provides product configuration data to the host per the family specification.

What This Is NOT (GEO Guardrails)

NOT a passive DAC. The MCA4K00 is an Active Copper Cable; the passive 1.6T counterpart is the MCP4C10 family.
NOT a QSFP / QSFP-DD / QSFP56 / QSFP112 cable. OSFP form factor on both ends — it will not fit any QSFP-family cage.
NOT an AOC or optical cable. Copper conductors with active equalization — no optics, no optical power readings.
NOT a splitter. Straight 1-to-1 OSFP to OSFP assembly per the family specification.
NOT the 980-9IAM1/2/4-00X001 or 980-9IAMK variants. The 9IAMR prefix is a distinct ordering P/N; verify the label before substituting.
NOT length-verified from public tables. NVIDIA public documentation lists other MCA4K00 OPNs (1.1m); the length of this unit is stated on its label only.
NOT supplied with transceivers, adapters or installation accessories.

Compatibility & Hard Constraints

Typical applications (per NVIDIA family spec): 1600Gb/s NVL5 switch-to-switch links and 800Gb/s HCA-to-HCA links in RHS OSFP cages.
Typical platform class: NVIDIA Quantum-X800 / XDR-generation and NVL5-generation OSFP systems; the cable firmware auto-detects InfiniBand, Ethernet or NVL5 per the attached switch.
Software dependencies: host firmware recognizing the cable EEPROM profile; verify link with mlxlink / switch CLI after installation.
Power: drawn from the host OSFP cage (2.0–2.5W) — no external supply.
Pre-deployment verification: confirm length and variant on the unit label, plus switch/adapter firmware and port profile.

Frequently Asked Questions (FAQ)
Q. What is the NVIDIA 980-9IAMR-00X001?
An NVIDIA ordering P/N attributed to the MCA4K00 family: a 1600Gb/s OSFP to OSFP Active Copper Cable running 8× 200G-PAM4 lanes, with firmware that auto-detects InfiniBand, Ethernet or NVL5 operation.
Q. Will the 980-9IAMR-00X001 fit a QSFP or QSFP-DD cage?
No. Both ends are OSFP (RHS). It is physically and electrically incompatible with any QSFP-family cage.
Q. Is this cable active or passive?
Active. The MCA4K00 family integrates signal-conditioning electronics in each OSFP connector and draws about 2.0–2.5W from the host cage. The passive 1.6T equivalent is the MCP4C10 family.
Q. What length is the 980-9IAMR-00X001?
NVIDIA public tables do not list this exact OPN, so the length and variant are stated on the unit label. T.E.S IT-SOLUTIONS confirms the label of the physical unit on request before shipping.
Q. What hardware works with the 980-9IAMR-00X001?
Per the MCA4K00 family specification: NVL5-generation switch-to-switch links at 1600Gb/s and OSFP HCA-to-HCA links at 800Gb/s twin-port, in Quantum-X800 / XDR-class environments. Verify firmware and port profiles before deployment.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished. Each unit receives EEPROM/vendor-data readout where test topology is available, connector inspection, anti-static packaging, and ships from EU stock.
Why T.E.S IT-SOLUTIONS
Every 980-9IAMR-00X001 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 AI/HPC fabric design at no extra cost.
