Arista QSFP-100G-FR 100GBASE-FR Single Lambda 1310nm 2km SMF QSFP28 Transceiver

The Arista QSFP-100G-FR is a QSFP28 100GBASE-FR transceiver that carries 100 Gigabit Ethernet on a single 1310nm wavelength over duplex single-mode fiber. Arista rates it for links up to 2km, and it connects with a standard duplex LC patch cord, so it runs on the same two-fiber cabling used by older 10G and 25G single-mode optics.

Because it is a single-lambda optic, the FR pairs with 400G parallel optics. Arista lists it as interoperable with 400GBASE-DR4, XDR4 and PLR4 modules, and its 400G-XDR4 can be broken out to four 100G-FR links. For the 400G end of that breakout, use the QDD-400G-XDR4 400G QSFP-DD transceiver. The FR does not link to a CWDM4 module, which uses four wavelengths, so both ends of a link should match. For runs up to 10km, the QSFP-100G-LR4 10km transceiver also uses duplex LC single-mode fiber.

Arista specifies a maximum power draw of 4.5W, transmit power of -2.4 to +4.0 dBm and a receive power range of -6.4 to +4.5 dBm. Digital optical monitoring (DOM) reports temperature, supply voltage, laser bias and optical power. The module fits Arista QSFP28 100G ports, including those on 7050CX3, 7060CX, 7280R and 7500R platforms.

This seller refurbished QSFP-100G-FR transceiver is tested, working, and covered by the NetworkTigers one-year warranty.
