Juniper QFX-QSFP-40G-LRM4 1330nm Transceiver

Product Description

The Juniper QFX-QSFP-40G-LRM4 is a Quad Small Form-factor Pluggable Plus (QSFP+) transceiver module that provides 40 Gigabit Ethernet connectivity. This specific module is designed for longer reach applications over multi-mode fiber (MMF) compared to standard 850nm SR4 transceivers. It operates at a wavelength of 1330nm, which allows for extended transmission distances while still utilizing the infrastructure of multi-mode fiber cabling. The QSFP+ form factor is chosen for its high port density, enabling efficient use of space in network racks, which is critical in modern data centers. The QFX-QSFP-40G-LRM4 uses an MPO/MTP connector, a compact connector designed to house multiple fiber strands, facilitating high-density cabling solutions. It supports transmission distances of up to 100 meters over OM3 or OM4 multi-mode fiber, making it suitable for inter-building connections or longer intra-data center links where single-mode fiber might not be deployed. As a hot-pluggable module, the QFX-QSFP-40G-LRM4 can be installed or removed from a QSFP+ port without interrupting the operation of the network device. This feature is essential for network flexibility and minimizing downtime during maintenance or upgrades. The module is intended for use in high-performance Ethernet networks, providing a robust solution for aggregation and core networking layers within data centers and enterprise environments. It typically includes Digital Diagnostics Monitoring (DDM) for performance monitoring.
