Product Description
The Juniper QFX-QSFP-40G-ESR is a high-performance Quad Small Form-factor Pluggable Plus (QSFP+) transceiver module designed to deliver 40 Gigabit Ethernet connectivity. This module is specifically engineered for short-reach applications, commonly found in data center environments where high port density and efficient cabling are paramount. It operates at an 850nm wavelength, which is standard for short-reach optical communication over multi-mode fiber (MMF). The QSFP+ form factor allows for a higher density of ports compared to traditional SFP+ modules, enabling network architects to deploy more bandwidth within a given rack space. The QFX-QSFP-40G-ESR utilizes an MPO/MTP connector, which is designed to accommodate multiple fiber strands in a single connector, simplifying installation and management for high-density deployments. It supports an extended reach of up to 400 meters over OM3 multi-mode fiber, making it suitable for inter-rack or intra-row connections within a data center. This transceiver is hot-pluggable, meaning it can be inserted or removed from a QSFP+ port without the need to power down the networking device. This feature is crucial for maintaining network uptime and facilitating seamless upgrades or maintenance. The QFX-QSFP-40G-ESR is designed to meet the demanding requirements of modern data centers, providing reliable and high-speed connectivity for server, storage, and network aggregation layers. It typically includes Digital Diagnostics Monitoring (DDM) for real-time performance insights.
