1000BASE-T Copper SFP Transceiver

The Finisar FCLF8522P2BTL is a hot-pluggable SFP transceiver designed for Gigabit Ethernet links over copper cabling. It suits network engineers and system integrators deploying 1000BASE-T connections in switches, routers or media converters.

100 m Reach Over RJ-45

The module delivers a 1.25 Gbps bi-directional data rate with a maximum link distance of 100 metres over standard twisted-pair cable. Its RJ-45 connector assembly fits the SFP MSA footprint while the extended case temperature range of -40°C to +85°C supports industrial environments.

Upgrades Fibre SFP Ports to Copper

This transceiver replaces a fibre SFP when the link must run over existing copper infrastructure. The jump is worth it when the deployment requires a fully metallic enclosure for low EMI, 1.05 W typical power dissipation and I2C access to the physical layer IC for diagnostics.

Questions about this item

Which of the Finisar 1000BASE-T Copper SFP models — FCLF8520P2BTL, FCLF8521P2BTL or FCLF8522P2BTL — should I choose?

The three models share the same SFP footprint, 1.25 Gbps rate, 100 m reach, extended temperature range and RoHS compliance. Select the exact part number your switch or router vendor lists as qualified.

What does the 1.25 Gbps transfer rate mean once the transceiver is installed in a switch?

It delivers a full-duplex Gigabit Ethernet link over Cat5e or better copper cable up to 100 metres, with the PHY accessible via the 2-wire serial bus for diagnostics.

The module uses an SFP interface — what does that cap in practice?

The SFP MSA footprint limits the module to 1.25 Gbps Ethernet over RJ-45 copper, hot-pluggable operation, and a maximum power draw of 1.05 W typical.
