$508.00

SKU: SRX-QSFP-40G-LR4-US Categories: , , OEM Equivalent: Juniper SRX-QSFP-40G-LR4

The US Transceivers compatible SRX-QSFP-40G-LR4 is a 40GBASE-LR4 QSFP+ transceiver module designed for long-reach single-mode fiber applications. Operating over four CWDM wavelengths (1271 nm, 1291 nm, 1311 nm, and 1331 nm) multiplexed onto a duplex LC single-mode fiber connection, this module delivers an aggregate data rate of 40 Gbps with a maximum reach of up to 10 km.

Built to meet IEEE 802.3ba and QSFP+ MSA standards, this TAA compliant module is a fully compatible replacement for use in Juniper SRX-series platforms. It supports Digital Diagnostics Monitoring (DDM/DOM), allowing real-time monitoring of temperature, voltage, TX power, RX power, and bias current for simplified network management and troubleshooting.

Ideal for enterprise core networking, data center interconnects, and campus aggregation deployments, this module provides a cost-effective, high-performance alternative that delivers reliable 40G connectivity without compromising on quality or compatibility.
