NVIDIA/Mellanox MCP1600-C0015 Compatible 100G QSFP28 4 x 25G NRZ Ethernet Passive Copper Twinax Cable, 1.5m (5ft)

Designed for hosts that recognize MCP1600-C0015, this QSFP28 to QSFP28 cable delivers 100G transmission over a fixed 1.5m (5ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

NVIDIA describes MCP1600 QSFP28 passive copper cables as four high-speed copper pairs operating at up to 25GbE per pair, with EEPROM product identification readable by the host. Its documentation distinguishes shorter no-FEC versions from longer RS-FEC versions, with specific variants at 2.5m and 3m. Check the exact suffix rather than selecting by length alone.

The listed modulation format is 4x 25G-NRZ to 4x 25G-NRZ. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.

The rated power consumption is ≤0.5W. Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 33.5mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

The intended application is 100G Ethernet. Listed interface and protocol references include QSFP28 MSA, SFF-8662, IEEE 802.3. Confirm that the host firmware and port configuration support the same operating mode.

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

The additional half metre beyond a one-metre assembly gives MCP1600-C0015 useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

MCP1600-C0015 occupies the middle of this family between MCP1600-C001 at 1m (3ft) and MCP1600-C002 at 2m (7ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Compatibility is more than matching the QSFP28 to QSFP28 shape. This assembly is prepared for hosts expecting MCP1600-C0015 and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

When ordering, specify MCP1600-C0015, cable length 1.5m (5ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
