  • LC duplex connector enables direct patch-panel integration
  • Digital Optical Monitoring gives real-time operating visibility
  • TAA compliant and MSA certified for guaranteed interoperability

AddOn 400GBase-LR4 QSFP-DD transceiver

The AddOn QSFP-DD transceiver delivers 400GBase-LR4 connectivity for data networking and optical network environments. It is built for operators who need a Juniper Networks compatible module that meets TAA requirements and initialises identically to the OEM part.

Fits QSFP-DD ports with LC single-mode fibre

The module plugs into a QSFP-DD cage and connects through a single LC duplex interface on single-mode fibre. MSA compliance and unique serialisation allow it to integrate without additional configuration, freeing the builder from proprietary lock-in while preserving DOM access for real-time link monitoring.

400 Gbit/s over 10 km at 1310 nm

The link runs at 400 Gbit/s across distances up to 10 km using a 1310 nm wavelength on SMF. Beyond that reach the module cannot guarantee performance, and it does not support multi-mode fibre or shorter-reach LR variants.

Questions about this item

How far can this QSFP-DD module reach over single-mode fiber at 400GBase-LR4?

The transceiver supports a 10km reach over single-mode fiber at 1310nm wavelength using an LC connector.

What thermal or power behaviour should I expect when the transceiver runs continuously at 400Gbit/s?

Digital Optical Monitoring provides real-time access to operating parameters including temperature and power levels during sustained operation.

Which patch cables and port type must I have ready for this transceiver to work?

You need LC-terminated single-mode fiber patch cables and a QSFP-DD port on your Juniper Networks switch or router.
