Dell 40 Gbps QSFP+ Transceiver

The Dell FTL4S1QE1C-FC is a genuine OEM QSFP+ optical transceiver module rated for 40 Gbps Ethernet connectivity. It is built for Dell Networking, PowerEdge and PowerConnect switches that accept QSFP+ ports. The part number 77KC3 identifies a hot-swappable replacement component for enterprise data-center infrastructure.

Sustained 40 Gbps data-centre throughput

Engineered for continuous high-bandwidth operation, the module complies with IEEE 802.3ba 40GBASE-SR4 specifications. It maintains the full 40 Gbps line rate across multi-fiber links without throttling during extended traffic loads. Hot-swap support allows insertion or removal while the switch remains powered, minimising service interruption during capacity upgrades.

Low power draw and silent operation

The energy-efficient design keeps power consumption minimal inside dense chassis, reducing aggregate thermal load across the rack. With no moving parts the transceiver operates silently, relying on the host switch airflow for cooling. MPO/MTP multi-fiber connectivity simplifies cable management while preserving signal integrity in normal production environments.
