- Description
Description
The Juniper JNP‑QSFP‑40G‑LR4 is a high‑speed 40 Gbps optical transceiver module designed for long‑reach connectivity over single‑mode fiber (SMF). It is compliant with the IEEE 802.3ba 40GBASE‑LR4 standard and QSFP+ Multi‑Source Agreement (MSA), enabling reliable 40 Gigabit Ethernet links over distances up to 10 km using duplex LC connectors and single‑mode fiber.
Operating at CWDM wavelengths (typically 1271 nm, 1291 nm, 1311 nm, and 1331 nm), this LR4 module uses four parallel 10 Gbps channels to achieve an aggregated 40 Gbps throughput, ideal for long‑distance data center interconnects (DCI), campus backbone links, and metro networks. Built‑in Digital Diagnostics Monitoring (DDM/DOM) provides real‑time visibility into key parameters such as temperature, optical power levels, and voltage for proactive health monitoring.
This module is a perfect choice for operators and network engineers who need to bridge high‑speed links over extended fiber runs without sacrificing performance or reliability.
Key Features:
• 40GBASE‑LR4 QSFP+ transceiver for long‑reach 40 Gbps Ethernet.
• Supports distances up to 10 km over single‑mode fiber (OS2) with LC duplex connectors.
• CWDM multiplexing of four 10 Gbps wavelengths for aggregate 40 Gbps throughput.
• Compatible with QSFP+ MSA and IEEE 802.3ba standards for broad interoperability.
• Digital Diagnostics Monitoring (DDM/DOM) for real‑time link performance insights.
• Hot‑pluggable form factor for easy installation and maintenance.
