40 Gigabit Ethernet Connectivity

The JNP-QSFP-40G-LR4 provides 40 Gigabit Ethernet connectivity in a compact QSFP+ form factor. It is designed for network environments requiring higher bandwidth than 10GbE while maintaining a practical optical reach for campus, data center and metropolitan networking applications.

Its 40GbE interface makes it suitable for server aggregation, switch interconnection, data center spine-leaf links and other high-bandwidth network applications.

40GBASE-LR4 Optical Standard

The JNP-QSFP-40G-LR4 uses the 40GBASE-LR4 optical standard. Juniper describes the module as 40 Gigabit optics capable of transmission up to 10km over single-mode fiber. :contentReference[oaicite:4]{index=4}

LR4 optics are designed for longer-reach 40GbE connectivity compared with short-range SR4 modules. This makes the JNP-QSFP-40G-LR4 particularly suitable where the network link extends beyond typical multi-mode fiber distances.

10km Transmission Distance

The Juniper JNP-QSFP-40G-LR4 supports transmission distances of up to 10km over compatible single-mode fiber. Juniper's official product information specifically identifies the module for up to 10km transmission on SMF. :contentReference[oaicite:5]{index=5}

The achievable distance in an installed network depends on fiber quality, optical loss, connector performance, patch panels, splices and the optical power budget of the complete link.

1310nm Optical Wavelength

The JNP-QSFP-40G-LR4 is a 1310nm LR4 optical module. Juniper's product documentation identifies the JNP-QSFP-40G-LR4 as a 40GBASE-LR4 optic for 10km transmission, while Juniper's current QFX10000 documentation specifies the optic as 1,310nm for up to 10km over SMF. :contentReference[oaicite:6]{index=6}

The 1310nm optical band is commonly used for long-reach single-mode fiber Ethernet applications because it provides suitable transmission characteristics for kilometer-scale links.

Single-Mode Fiber Support

The JNP-QSFP-40G-LR4 is designed for Single-Mode Fiber (SMF). Juniper's Hardware Compatibility Tool specifically lists SMF and a maximum reach of 10km for this optic. :contentReference[oaicite:7]{index=7}

Use compatible single-mode fiber infrastructure and appropriate LC duplex patch cables when deploying the module. Multi-mode fiber should not be substituted simply because the connector type is physically compatible.

Duplex LC PC/UPC Connector

The module uses a Duplex LC PC/UPC optical connector. Juniper's Hardware Compatibility Tool explicitly identifies this connector type for JNP-QSFP-40G-LR4. :contentReference[oaicite:8]{index=8}

The duplex LC interface provides separate transmit and receive optical paths through the two fiber strands.

Digital Optical Monitoring

Juniper lists Digital Optical Monitoring as available for the JNP-QSFP-40G-LR4. :contentReference[oaicite:9]{index=9}

Digital optical monitoring can provide operational information such as optical parameters and module conditions when supported by the host networking platform and software.

QSFP+ Form Factor

The JNP-QSFP-40G-LR4 uses the QSFP+ form factor. QSFP+ is widely used for 40GbE networking and provides a compact high-density optical interface for compatible switches, routers and other networking equipment.

Juniper Compatibility

Juniper's Hardware Compatibility Tool lists JNP-QSFP-40G-LR4 across compatible Juniper networking platforms. The optic is identified for platforms including ACX710, ACX5000, ACX5448 and other supported systems. :contentReference[oaicite:10]{index=10}

Juniper also documents JNP-QSFP-40G-LR4 for platforms including the MX10003 and EX9253, subject to the relevant line card, interface and software requirements. :contentReference[oaicite:11]{index=11}

Compatibility should always be checked against the exact Juniper switch, router, line card, interface module and Junos/Junos OS Evolved release before installation.

High-Speed Data Center Networking

The JNP-QSFP-40G-LR4 is suitable for high-bandwidth data center networking applications where 40GbE connectivity and longer optical reach are required.

• Data center switch uplinks
• Spine-to-leaf connectivity
• Core network links
• Switch-to-switch interconnection
• Server aggregation
• Enterprise backbone connectivity
• Campus network interconnection
• Service-provider network infrastructure

40G LR4 vs 40G SR4

Juniper's product documentation distinguishes JNP-QSFP-40G-LR4 from SR4 optics: the LR4 module is specified for up to 10km over SMF, while Juniper's SR4 module is specified for up to 150m over MMF. :contentReference[oaicite:12]{index=12}

Breakout Capability

Juniper's Hardware Compatibility Tool identifies the JNP-QSFP-40G-LR4 as not breakout capable. :contentReference[oaicite:13]{index=13}

Therefore, this module should not be marketed as a 4x10GbE breakout optic. A dedicated Juniper 40G breakout optic, such as the JNP-QSFP-4X10GE-LR, is a different product designed for 4x10GbE breakout connectivity. :contentReference[oaicite:14]{index=14}

Network Applications

• 40GbE switch uplinks
• Data center backbone links
• Spine-leaf network connections
• Core-to-distribution connectivity
