Arista 400GBASE-LR8 QSFP-DD Transceiver, 10 km Duplex Single-Mode
QDD-400G-LR8 · Refurbished · 1 year warranty
Quantity (units)
Overview
The Arista QDD-400G-LR8 reaches 10 km on duplex single-mode fiber in a QSFP-DD package. The title identifies the standard as 400GBASE-LR8.
Optics at both ends of a link must use the same standard, so when you extend an existing LR8 link you need another LR8. Match the pair by part number and standard rather than by reach alone. Switch vendors keep lists of optics they support, so check that this module and its standard are accepted on your port before ordering. If you are unsure, send us the switch model and we will help you check.
The module has a single port and fits QSFP-DD cages at 400GbE. Order it new, refurbished or used. New and refurbished units list 1 year or 3 years of warranty, and used lists 90 days.
