Arista QSFP-100G-DR 100GB BASE-DR 500m SMF QSFP28 Transceiver

The Arista QSFP-100G-DR is a QSFP28 100GBASE-DR transceiver that carries 100 Gigabit Ethernet on a single 1310nm wavelength over duplex single-mode fiber. Arista rates it for links up to 500 meters, and it connects with an ordinary duplex LC/UPC patch cord, so it runs on the same two-fiber single-mode cabling already used for 10G and 25G optics.

The single-lambda design is what separates the DR from four-wavelength parts such as LR4 and CWDM4. Arista lists it as interoperable with 400GBASE-DR4, XDR4 and PLR4 optics at up to 500 meters, so one 400G port can be broken out to four 100G-DR links. For the 400G end of that breakout, use the QDD-400G-DR4 400G QSFP-DD transceiver. If a run is longer than 500 meters, the QSFP-100G-FR 2km single-lambda transceiver uses the same duplex LC cabling.

Arista specifies a maximum power draw of 4.5W, transmit power of -2.9 to +4.0 dBm and a receive power range of -5.9 to +4.0 dBm. Digital optical monitoring (DOM) reports temperature, supply voltage, laser bias and optical power, so link health can be checked from the switch. The module fits Arista QSFP28 100G ports, including those on 7050CX3, 7060CX, 7280R and 7500R platforms.

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