Mellanox LinkX splitter cable with one QSFP56 end splitting to two QSFP56 ends, 6.56 ft

Mellanox Technologies

Mellanox LinkX MCP7H50-H002R26 200Gb/s HDR QSFP56 to 2×100Gb/s HDR100 QSFP56 splitter cable 6.56 ft

SKU CH-RW0G-S5KTJ

Splits a 200Gb/s HDR QSFP56 port into two 100Gb/s HDR100 QSFP56 links over 6.56 ft of passive copper

  • 200 Gb/s HDR bandwidth from a single QSFP56 port
  • Splits into two 100 Gb/s HDR100 QSFP56 links
  • Passive copper design lowers power draw in the rack
  • 56 ft length suits short-range data-centre runs
  • Factory-sealed LinkX cable tested for out-of-the-box reliability

Splitter cable for 200Gb/s HDR links

This Mellanox LinkX cable splits a single 200Gb/s HDR QSFP56 port into two 100Gb/s HDR100 QSFP56 connections. It is built for data-centre interconnects where a switch or adapter needs to serve two downstream ports from one uplink. The hybrid fibre-optic construction carries the signal over a 6.56 ft run. Each QSFP56 end includes an EEPROM that the host system can read for inventory and diagnostics.

Capacity and headroom

The cable delivers 200Gb/s aggregate bandwidth, divided into two 100Gb/s lanes for the splitter ends. It comfortably handles short-reach InfiniBand HDR traffic between racks or within a cabinet. The passive copper design keeps latency low and power draw minimal. It runs out of reach beyond the 6.56 ft length, so longer links need active or optical alternatives.

Build quality and daily implications

Rigorous factory testing aims to give a reliable out-of-the-box experience with durable connectors. The splitter layout means one cable manages two links, reducing cable count and improving airflow in dense patches. QSFP56 connectors lock in place for secure mating during rack moves. The hybrid fibre-optic build is lighter than an all-copper DAC of the same speed, easing strain on port cages.

Questions about this item

Will the 200Gb/s HDR QSFP56 end work with my existing 100Gb/s HDR100 QSFP56 switch ports?

The splitter cable connects a single 200Gb/s HDR QSFP56 port to two separate 100Gb/s HDR100 QSFP56 ports, so each 100Gb/s port operates at its native speed.

How can I verify the 25 GB/s lanes are active after plugging in the MCP7H50-H002R26?

Each QSFP56 connector includes an EEPROM that the host system reads to confirm product information and link status for the four 25 GB/s lanes per port.

Does the 6.56 ft hybrid fiber optic splitter cable include both QSFP56 ends or do I need separate modules?

The cable has a fixed 200Gb/s HDR QSFP56 connector on one end and two fixed 100Gb/s HDR100 QSFP56 connectors on the other; no separate modules are required.
