Frequently Asked Questions
What is the maximum reach of the Juniper QSFPP-40G-LR4-C transceiver? +
The QSFPP-40G-LR4-C is designed for long-reach applications, supporting distances of up to 10 kilometers over single-mode fiber (SMF). This makes it an ideal solution for interconnecting data centers, linking campus buildings, or extending network reach across metropolitan area networks while maintaining high-speed 40G throughput.
Does the QSFPP-40G-LR4-C support WDM technology? +
Yes, this transceiver utilizes Course Wavelength Division Multiplexing (CWDM) technology. It multiplexes four wavelengths onto a single fiber pair, allowing for efficient 40G transmission. This design ensures compatibility with standard 40GBASE-LR4 interfaces and maintains signal integrity across the specified 10-kilometer distance without requiring additional infrastructure complexity.
Which connector type does the QSFPP-40G-LR4-C require for fiber termination? +
This module features an LC duplex connector interface. When deploying this transceiver, ensure your fiber optic patch cables are terminated with LC connectors to guarantee a secure physical connection. This standard interface simplifies integration with existing structured cabling systems currently utilized in high-density enterprise environments.
Is the QSFPP-40G-LR4-C hot-swappable in Juniper switches? +
Absolutely. The QSFPP-40G-LR4-C is designed to be hot-swappable, allowing you to install or replace the module while the host switch is powered on and running. This feature significantly minimizes network downtime during upgrades or maintenance windows, ensuring your enterprise connectivity remains continuous and highly available.
How much power does the QSFPP-40G-LR4-C consume during operation? +
The module is optimized for power efficiency consistent with industry standards for QSFP+ LR4 optics. Typical power consumption remains well within the thermal limits of standard Juniper QSFP+ ports. Maintaining proper airflow in your rack environment is recommended to ensure the transceiver operates within its ideal thermal performance envelope.
Can I use the QSFPP-40G-LR4-C to connect to a 10G-only port via a breakout cable? +
While the QSFP+ form factor is physically compatible with various ports, the LR4 standard is specifically engineered for 40GbE aggregated signals. It is not intended for use with breakout cables to provide 10G connectivity. For 40G to 10G transitions, please verify that your specific switch hardware supports port-splitting configurations for this transceiver model.
What kind of network environment is best suited for the QSFPP-40G-LR4-C? +
This transceiver is best suited for enterprise backbone and data center environments that require high-bandwidth connectivity over single-mode fiber. It is perfect for top-of-rack or end-of-row switching scenarios where long-reach capabilities are necessary to overcome distance limitations of copper or multimode fiber solutions.
Are there specific configuration steps required after installing the QSFPP-40G-LR4-C? +
Typically, once the module is inserted and the fiber cable is connected, the Juniper switch will automatically detect the transceiver and update the interface status. You may need to verify the operational state using the device's command-line interface to ensure the optical power levels are within the expected range for your specific fiber link.
How can I obtain a bulk quote for multiple QSFPP-40G-LR4-C units? +
Requesting a bulk quote is simple. Please reach out to our sales team directly through our website with the specific SKU and quantities required. We are experienced in handling large-scale infrastructure projects and can provide competitive pricing structures tailored to your organization’s procurement needs and inventory requirements.
