Product Description
The Juniper QFX-QSFP-40G-LR4 is a high-performance QSFP+ (Quad Small Form-factor Pluggable Plus) transceiver module engineered for 40 Gigabit Ethernet (40GbE) networks. It utilizes a 1310nm wavelength, which is characteristic of Long Reach (LR) transceivers, enabling data transmission over significant distances on single-mode fiber optic cables. This makes it an ideal solution for data center interconnects, campus backbones, and other applications requiring extended reach. This transceiver is specifically designed to comply with the IEEE 802.3ba standard for 40GbE and is optimized for use with Juniper Networks' QFX series switches and other compatible networking equipment. The LR4 designation indicates that it employs four independent optical lanes, each operating at 10Gb/s, aggregated to achieve the total 40Gb/s throughput. The use of a 1310nm wavelength is crucial for achieving the extended reach capabilities. The module typically features an LC duplex connector, providing a secure and reliable physical interface for the fiber optic patch cords. Its robust design ensures stable performance and low latency, critical for demanding enterprise and service provider environments. The QFX-QSFP-40G-LR4 is a key component for building scalable and high-bandwidth network infrastructures.
