R0Z27A — Aruba 400G QSFP-DD LC FR4 2km SMF xcvr

The R0Z27A is a 400 Gbps QSFP-DD transceiver from HPE Aruba compliant with the 400GBASE-FR4 standard, providing links of up to 2 kilometres over single-mode fibre (SMF) via an LC duplex connector. Using FR4 technology with 4 wavelengths, it achieves 400 Gbps over a pair of standard SMF fibres, distinguishing it from DR4 and SR8 variants by its reach and LC interface.

This module is the reference for 400G inter-data-centre or inter-room links over SMF at short-to-medium distances (up to 2 km), combining high capacity with conventional LC connectivity. Ideal for operators and large enterprises deploying ultra-high-bandwidth Aruba networks between nearby buildings. Genuine hardware, manufacturer warranty.
