FCLF-8520-3 1000BASE-T Copper SFP Optical Transceiver Ethernet over Cat 5 cable

FCLF-8520-3 1000BASE-T Copper SFP Optical Transceiver Ethernet over Cat 5 cable

● Up to 1.25Gb/s bi-directional data links
● Hot-pluggable SFP footprint
● Extended case temperature range -0°C to +85°C
● Fully metallic enclosure for low EMI
● Low power dissipation (1.05W typical)
● Compact RJ-45 connector assembly
● RoHS-6 compliant (lead-free)
● Access to physical layer IC via 2-wire serial bus
● 10/100/1000 BASE-T operation in host systems with SGMII interface

● 1.25 Gigabit Ethernet over Cat 5 cable

● FCLF-8520/8521-3 1000BASE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA). They are compatible with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE Std 802.3 . The 1000BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features.

● The FCLF-8520-3 uses the SFP’s RX_LOS pin for link indication, and 1000BASE-X autonegotiation should be disabled on the host system. The FCLF-8521-3 is compatible with 1000BASE-X auto-negotiation, but does not have a link indication feature (RX_LOS is internally grounded). See AN-2036 (“Frequently Asked Questions Regarding Finisar’s 1000BASE-T SFPs”) for a more complete explanation on the differences between the two models and details on applications issues for the products.

● The optical transceiver is compliant per the RoHS Directive 2011/65/EU. See Finisar Application Note AN-2038 for more details.
