Frequently Asked Questions

What is the maximum reach of the Finisar FTL4C1QE1C 40GBASE-LR4 transceiver? +

The Finisar FTL4C1QE1C is designed for long-reach applications, supporting link lengths of up to 10 kilometers over standard single-mode fiber (SMF). This makes it an ideal solution for connecting data centers or enterprise campus locations that require high-speed 40G connectivity beyond the limitations of multimode fiber cabling.

Which interface standard does the FTL4C1QE1C utilize for 40G connectivity? +

This module adheres to the 40GBASE-LR4 standard, utilizing a QSFP+ form factor. It multiplexes four channels of 10Gbps data into a single-mode fiber link using WDM technology. It is specifically engineered to provide high-bandwidth performance while maintaining strict compatibility with industry-standard IEEE 802.3ba networking hardware.

Does the Finisar FTL4C1QE1C require special fiber optic cabling? +

Yes, this transceiver requires single-mode fiber (SMF) cabling with an LC duplex connector interface. Because it operates over a long-range wavelength, it is not compatible with multimode fiber cables. Ensure your existing fiber plant uses appropriate single-mode patch cords to maintain signal integrity and meet the specified 10km distance requirement.

Is the FTL4C1QE1C compatible with various 40G QSFP+ switch ports? +

The FTL4C1QE1C is designed for high interoperability and follows the QSFP+ MSA (Multi-Source Agreement) specifications. It is compatible with most enterprise-grade switches and routers that feature standard QSFP+ ports. We recommend verifying your specific switch manufacturer's compatibility matrix to ensure optimal performance and seamless integration with your existing network architecture.

What are the primary use cases for deploying the Finisar 40GBASE-LR4 module? +

These modules are most commonly deployed in backbone networks, high-speed campus interconnects, and data center leaf-to-spine links. By providing a 40G connection over single-mode fiber, they allow network architects to extend high-capacity bandwidth across significant distances, replacing multiple lower-speed connections with a single, reliable optical interface.

How does the power consumption of the FTL4C1QE1C affect switch thermal performance? +

The FTL4C1QE1C is optimized for power efficiency within a standard QSFP+ power envelope. While all optical transceivers generate heat, this module meets industry thermal management standards, ensuring it can operate reliably within high-density line cards. Proper switch-level airflow and rack-level cooling are essential to maintain stable operating temperatures during sustained 40Gbps data throughput.

Does this transceiver support Digital Diagnostic Monitoring (DDM)? +

Yes, the Finisar FTL4C1QE1C includes advanced digital diagnostic features. This allows network administrators to monitor real-time parameters such as optical output power, receiver input power, temperature, and supply voltage directly from the switch console. These insights are vital for proactive troubleshooting and ensuring the link remains within its operational performance thresholds.

What is the connector type on the FTL4C1QE1C module? +

This transceiver features a standard LC duplex optical connector. This is a common, compact design that simplifies cabling management in high-density environments. The LC interface ensures a secure, low-loss physical connection to your single-mode fiber network, providing a stable link for your 40G optical signals.
