Description
A 400 Gigabit QSFP-DD short-reach module with eight 50G lanes, Juniper part code 740-114928. It targets leaf-spine links inside a data hall on 400G switches and routers. Juniper marks it breakout capable, so it can serve 8x50G or 4x100G designs on supported hosts. The interface is a 16-fibre MPO connector, with light in the 840 to 860 nm range. Juniper gives 12 W in high-power mode and 1.5 W in low-power mode. Cabling for QDD-400G-SR8: use a multimode trunk with MPO-16 connectors and correct polarity, OM3 or OM4. The headline reach is 70 m on OM3 · 100 m on OM4 and OM5, so measure the installed link loss before ordering. The host needs a free QSFP-DD cage that runs at 400G; Juniper's tool names QFX5130-32CD, QFX5230-64CD, QFX5240-64QD among the platforms where this code is supported, and the model page also gives the minimum software release for each platform. Clean the connectors before insertion and keep dust caps on unused ports.
