JNP-QSFP-4X10GE-LR JUNIPER Juniper QFX/MX Series Optical Transmission Module

The Juniper JNP-QSFP-4X10GE-LR is a QSFP+ optical transceiver module that provides breakout connectivity from a single 40GbE QSFP+ port to four individual 10 Gigabit Ethernet channels using LR (Long Range) optics. This module utilises MPO/MTP connectors and supports single-mode fibre transmission over distances up to 10 kilometres per channel.

This transceiver is designed for deployment in Juniper Networks switching and routing platforms that support QSFP+ interfaces, including the QFX series data centre switches and MX series routers. It enables flexible port density configurations, allowing network engineers to maximise interface utilisation by breaking out 40GbE ports into multiple 10GbE connections.

The JNP-QSFP-4X10GE-LR is well suited for data centre interconnects, spine-leaf architectures, and enterprise core network deployments where long-reach 10GbE connectivity is required from 40GbE-capable infrastructure. It supports IEEE 802.3ba standards for 40GBASE-LR4 breakout applications.
