Frequently Asked Questions

What is the primary function of the Finisar FTLC9555REPM QSFP28 transceiver? +

The Finisar FTLC9555REPM is a high-performance QSFP28 optical transceiver module designed to support 100G Ethernet connectivity. It serves as a reliable interface for high-density data center environments, enabling efficient data transmission over single-mode fiber infrastructure for long-reach applications. Its compact form factor ensures maximum port density for modern networking switches and routers.

What type of cabling does the FTLC9555REPM require for optimal performance? +

This module is engineered for single-mode fiber (SMF) deployments. To maintain signal integrity and meet the specified reach requirements, users should utilize industry-standard single-mode fiber cabling with appropriate LC connectors. It is critical to ensure that the fiber infrastructure is properly cleaned and inspected to prevent optical loss and maximize the transmission distance of the 100G link.

Can the FTLC9555REPM be used in existing 40G networking equipment? +

The FTLC9555REPM is specifically optimized for 100G QSFP28 interfaces. While the QSFP28 form factor is physically compatible with QSFP+ ports, the electrical and optical signaling requirements for 100G operation differ significantly from 40G standards. Always verify the host device's port configuration and software support before attempting to deploy this transceiver in legacy 40G hardware slots.

How does the FTLC9555REPM perform in high-temperature data center environments? +

Finisar engineers have designed this transceiver to operate effectively within standard data center thermal envelopes. By adhering to proper airflow and cooling practices within your server rack or switch chassis, the module maintains stable optical output and sensitivity. Consistently monitoring the module’s internal temperature via the digital diagnostic monitoring (DDM) interface helps ensure sustained reliability and performance.

Does the FTLC9555REPM support Digital Diagnostic Monitoring (DDM)? +

Yes, this transceiver includes integrated digital diagnostic monitoring functions. This feature provides real-time access to critical operating parameters, including optical output power, input power, temperature, laser bias current, and transceiver supply voltage. These diagnostics are essential for proactive network maintenance, allowing administrators to identify potential link degradation before a service-impacting failure occurs.

What are the power consumption characteristics of this QSFP28 module? +

The FTLC9555REPM is designed with power efficiency in mind, adhering to the power constraints typically associated with QSFP28 standards. By minimizing heat dissipation, it reduces the overall thermal load on your switching hardware. For specific power budget planning, consult the host device’s data sheet to ensure that the aggregate power draw across all populated ports remains within the system's capacity.

Is the FTLC9555REPM compatible with various switch vendors? +

The Finisar FTLC9555REPM is built to follow industry-standard MSA (Multi-Source Agreement) specifications. This broad compatibility allows it to function across a wide range of top-tier networking platforms that support standard QSFP28 optics. Before deployment, confirm that your specific switch or router firmware supports the transceiver by checking the device's compatibility matrix or qualified optics list.

What is the typical reach of the FTLC9555REPM in a 100G network? +

This module is intended for long-reach transmission over single-mode fiber. It provides the necessary optical power and receiver sensitivity to span distances significantly further than standard short-reach multi-mode optics. The exact distance is subject to fiber quality, patch panel connections, and signal attenuation across the total optical link, making it an excellent choice for interconnecting switches across rows or within larger facility footprints.
