Description

The Finisar FTLC1121RFNL is a high-performance 100GBASE-PSM4 QSFP28 optical transceiver designed for cost-effective short-reach 100 Gigabit Ethernet connectivity over single-mode fiber (SMF). Operating at 1310 nm, it uses 4 parallel transmit and receive lanes (4 Tx / 4 Rx) to deliver an aggregate 100 Gb/s data rate.

This module supports transmission distances of up to 500 meters over SMF, making it ideal for data-center interconnects, leaf-spine architectures, and high-density switch-to-switch links where MPO cabling is preferred.

Housed in a hot-pluggable QSFP28 form factor, the FTLC1121RFNL supports full DOM/DDM digital diagnostics, enabling real-time monitoring of temperature, voltage, laser bias current, and optical power. It is compliant with QSFP28 MSA and IEEE standards, ensuring broad interoperability and reliable performance.
