Mellanox QSFP28 100G 850nm MPO transceiver module

Mellanox Technologies

Mellanox Technologies QSFP28 100G 850nm MPO switch module

SKU CH-T64G-FJ6Y0

Transmits 100Gb/s over 850nm multimode fibre using an MPO connector up to 100m

  • 100 Gb/s throughput for high-density fabrics
  • 850 nm optics reach 100 m over multimode fibre
  • Single MPO connector simplifies cabling in dense racks
  • QSFP28 form factor fits standard switch cages
  • Validated for Mellanox ConnectX-4 adapter compatibility

Mellanox QSFP28 100G optical module

This Mellanox Technologies switch module is a QSFP28 transceiver designed for optical network and data networking environments. It operates at 100 Gigabit Ethernet speeds using 100GBase-X technology over optical fiber. The module features a single MPO connector and an 850nm wavelength for short-range connectivity.

Suits Mellanox ConnectX-4 adapter cards.

This module suits administrators deploying or expanding Mellanox-based InfiniBand EDR or 100GbE fabrics where the switch and adapter ports are qualified for this part. It is not for buyers who need compatibility with non-Mellanox switches, routers or network interface cards, nor for links that must exceed the supported 100-metre reach on multimode fiber.

850nm wavelength defines 100-metre multimode reach

The 850nm optical wavelength determines that this transceiver is built for multimode fiber runs up to 100 metres. If the link distance is longer, or if the installed cabling is single-mode, this module will not work and a different wavelength part is required.

Highlights

  • 100 Gb/s throughput for high-density fabrics
  • 850 nm optics reach 100 m over multimode fibre
  • Single MPO connector simplifies cabling in dense racks
  • QSFP28 form factor fits standard switch cages
  • Validated for Mellanox ConnectX-4 adapter compatibility

Questions about this item

What MPO connector and fiber type does the 100G QSFP28 module require for the 850nm link?

The module uses a single MPO 100GBase-X interface and is designed for multimode optical fiber at 850nm.

How do you correctly seat the QSFP28 transceiver in a Mellanox ConnectX-4 adapter card?

Align the module with the cage, push firmly until the latch clicks, then verify the link LED before tightening any cable strain relief.

When should the MPO patch cords be inspected or replaced to maintain the 100m reach?

Inspect end faces before each install and replace cords showing contamination, scratches or insertion-loss drift that exceeds the link budget.
