The QDD-4X100G-LR is a 400G QSFP-DD optical transceiver engineered as a drop-in equivalent for Juniper platforms,, a like-for-like replacement that the host accepts as native, hot-swappable and ready out of the box.

At single-mode reach this module bridges the middle ground — access to aggregation, building-to-building campus links, and short data-center interconnect spans that outrun multimode but never need amplification. The single-mode path keeps the signal clean across the full distance over existing OS1 and OS2 plant. It operates 10km.
Because it is coded to the Juniper host platform, the switch or router reads it as a factory module — clean in diagnostics, free to mix with OEM and other compatible optics in the same chassis, and needing no firmware exceptions.
Each unit is programmed to match Juniper host values and bench-tested for traffic conformity, DOM-threshold accuracy, and optical cleanliness before it leaves the bench. Class 1 laser certified and RoHS compliant.
