Black QSFP28 passive copper cable, two metres long

Mellanox Technologies

Mellanox Technologies Passive Copper Cable IB EDR QSFP28 2m Black MCP1600E002E30 network ethernet cable

SKU CH-PPEP-QFPQ3

A 2-metre passive copper cable with QSFP28 connectors supports 100 Gb/s data rates and meets SFF-8665 compliance

  • Supports up to 100Gb/s data rate for high-speed networking
  • SFF-8665 compliant QSFP28 connector ensures broad compatibility
  • Hot-pluggable design allows installation without system shutdown
  • LSZH jacket reduces toxic smoke emission in fire events
  • Operates reliably from 0 to 70°C case temperature

What this cable delivers

This Mellanox Technologies passive copper cable carries up to 100Gb/s over a two-metre QSFP28 link. It suits data-centre racks and high-performance clusters that need deterministic, low-latency connectivity between switches, adapters or storage nodes. The SFF-8665 compliant form factor plugs directly into standard EDR InfiniBand or 100GbE ports without extra transceivers.

Behaviour under sustained load

The cable operates from 0 to 70 °C case temperature on a single 3.3 V supply, so it maintains signal integrity across a fully populated rack without active cooling. A bit error rate better than 1E-15 means sustained throughput stays clean during long-running compute or storage jobs. Hot-pluggable insertion lets you add or replace links without draining the chassis.

Build and daily handling

An LSZH jacket reduces smoke and halogen release in dense cable trays, meeting RoHS requirements for modern facilities. The passive copper construction avoids the power draw and failure points of optical modules while keeping the bend radius practical for tight routing. QSFP28 latches secure each end firmly, preventing accidental disconnects during maintenance cycles.

Questions about this item

How much heat does the 2 m passive copper cable add to a rack that runs at the 70 °C case limit all day?

The cable is passive, so it adds no active heat; the only thermal load is the 3.3 V supply current, and the case is rated for 0‑70 °C operation.

Which port type must my switch or NIC already provide for this QSFP28 cable to link?

You need a QSFP28 port that supports 100 Gb/s InfiniBand EDR and the SFF‑8665 electrical interface.

Will the 2 m cable work reliably in a channel that also includes older 28 Gb/s lanes?

The cable is specified for 100 Gb/s with a BER better than 1E‑15; mixing slower lanes would require separate negotiation on each end.
