NEW Arista QSFP-100G-SWDM4 100GB BASE-SWDM4 70m OM3/100m Duplex MMF QSFP28

The Arista QSFP-100G-SWDM4 is a QSFP28 100GBASE-SWDM4 optical transceiver for 100G links over duplex multimode fiber. It transmits at 850, 880, 910, and 940nm. It reaches up to 70 meters on OM3 and 100 meters on OM4 and uses a duplex LC connector.

It uses shortwave wavelength division multiplexing to carry 100G over a single duplex multimode pair. Use a matching 100GBASE-SWDM4 optic at the far end of the link unless Arista lists the pairing above, and use multimode patch cables of the grade your reach requires.

If you need a different reach, the QSFP-100G-PSM4 100GBASE-PSM4 transceiver and the QSFP-100G-SR4 100GBASE-SR4 transceiver are also available. A seller refurbished QSFP-100G-SWDM4 is also available.

Arista publishes a transceiver compatibility guide that lists which switch platforms and EOS releases support each module, so check it for your switch before you order.

OM3 and OM4 multimode patch cables are normally aqua, and some OM4 cables are violet. Check that every patch cord and panel in the path matches the fiber grade your reach requires.

Keep the dust caps on the optic and the fiber until you are ready to connect them, and clean the connector end faces before you plug them in. Most failed optical links come down to a dirty connector.

This QSFP-100G-SWDM4 is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
