Arista QSFP-100G-SWDM4 100Gbps transceiver

This Arista QSFP-100G-SWDM4 transceiver delivers 100Gbps Ethernet connectivity over multimode fibre using shortwave wavelength division multiplexing. It fits a standard QSFP28 port and operates at an 850nm optical reach. The module is supplied new with firmware updated and tested.

Suits links up to 500m on duplex MMF.

This part suits data-centre operators extending 100GbE links up to 500 metres over existing duplex multimode infrastructure. Buyers needing longer reach, single-mode fibre compatibility or a different form factor should select another module.

SWDM4 over duplex MMF at 850nm decides fit

The single specification that decides fit is the SWDM4 connection type running at 850nm over duplex multimode fibre for 500 metres. Match this exactly to your switch port and cable plant before ordering.

Questions about this item

Will the QSFP-100G-SWDM4 transceiver need firmware updates after installation?

Firmware is updated before shipment; further updates follow the switch vendor's maintenance schedule.

What limits continuous throughput on the 100Gbps SWDM4 link?

The 500 m multimode reach at 850 nm is the primary distance constraint under sustained load.

How much heat does the QSFP28 module generate during all-day operation?

Typical QSFP28 power draw stays within the MSA thermal envelope for 100G SWDM4 optics.
