Product Description
The Juniper QFX-QSFP-40G-ESR4 is a high-performance transceiver module designed to deliver 40 Gigabit Ethernet connectivity over multimode fiber optic cables. Utilizing the QSFP+ (Quad Small Form-factor Pluggable Plus) form factor, it supports four independent data lanes, each operating at 10Gb/s, to aggregate into a total bandwidth of 40Gb/s. This module is specifically designed for extended reach applications, enabling data transmission up to 300 meters, making it suitable for demanding data center environments and campus networks. This transceiver operates at a wavelength of 850nm and employs an MPO (Multi-fiber Push On) connector, which is standard for parallel optics. The MPO connector houses multiple fiber strands within a single connector body, facilitating high-density cabling and simplifying installation. The ESR4 designation indicates its capability for extended reach over multimode fiber, providing a cost-effective solution for short to medium-distance links where higher bandwidth is required. Engineered for use with Juniper Networks' QFX series switches and other compatible networking equipment, the QFX-QSFP-40G-ESR4 is crucial for building high-speed network backbones, connecting servers to top-of-rack switches, and enabling efficient data center interconnectivity. Its ability to deliver 40Gb/s speeds over multimode fiber makes it a key component for modern, high-performance network infrastructures.
