Adafrut 40GBASE-UNIV QSFP+ optical transceiver module with duplex LC ports

Adafruit

Adafruit 40GBASE-UNIV QSFP+ Optical Transceiver 2 in 1 accessory

SKU CH-X523-B4466

A 40G QSFP+ optical transceiver connects switches over 150 m multimode or 2 km single-mode fibre at 1310 nm with digital diagnostics and 3.5 W maximum power draw

  • Reliable long-term operation with a maximum power draw of 3.5W
  • Works in demanding environments across a commercial temperature range of 0 to 70C (32 to 158F)
  • Real-time digital optical monitoring provides strong diagnostic capabilities for link health
  • Extends reach up to 150m on OM3 multimode fiber or 2km on single-mode fiber at 1310nm
  • Hot-pluggable QSFP+ form factor compliant with SFF-8436, QSFP MSA, ROHS and IEEE 802.3ba

40GBASE-UNIV QSFP+ transceiver

The Adafruit 40GBASE-UNIV QSFP+ optical transceiver connects network switches and routers at 40 Gbps over duplex LC single-mode or multimode fiber. It targets network engineers and data-centre operators who need a hot-pluggable module for link upgrades or new deployments. The module operates across a commercial temperature range of 0 to 70 C.

Sustained-load behaviour

A maximum power draw of 3.5 W keeps thermal output low during continuous operation, supporting prolonged service life inside densely populated chassis. Built-in digital diagnostic monitoring reports real-time optical parameters so administrators can detect degradation before a link fails. The transceiver is validated in targeted switch devices to maintain reliability under constant traffic.

Reach and fiber compatibility

The module transmits up to 150 m on OM3 multimode fiber or 2 km on single-mode fiber at 1310 nm, allowing a 10G to 40G upgrade without replacing existing multimode cabling. It complies with SFF-8436, QSFP MSA, RoHS and IEEE 802.3ba. Buyers who need longer single-mode reach or a different wavelength must select another part.

Questions about this item

How much power does the 40GBASE-UNIV QSFP+ module draw when running continuously?

Maximum power consumption is 3.5 W, so it stays cool within the 0 to 70 °C commercial temperature range during all-day operation.

What patch cables and switch ports are required to use this transceiver?

Duplex LC single-mode or OM3 multimode fibre cables and a QSFP+ port compliant with SFF-8436 and IEEE 802.3ba.

Will the 1310 nm optics work with my existing 10 G OM3 multimode runs?

Yes, it transmits up to 150 m on OM3 multimode fibre, letting you upgrade 10 G links to 40 G without re-cabling.
