FCLF-8520/8521-3 1000BASE-T SFP Product Specification
V.
Notes:
1. Clock tolerance is +/- 50 ppm
2. By default, the FCLF-8520/8521-3 is a full duplex device in preferred master mode
3. Automatic crossover detection is enabled. External crossover cable is not required
4. 10/100/1000 BASE-T operation requires the host system to have an SGMII interface
with no clocks, and the module PHY to be configured per Application Note AN-2036.
With a SERDES that does not support SGMII, the module will operate at 1000BASE-T
only.
VI. Environmental Specifications
The FCLF-8520/8521-3 has an extended range from 0°C to +85°C case temperature as
specified in Table 8.
VII. Serial Communication Protocol
All Finisar SFPs support the 2-wire serial communication protocol outlined in the SFP
MSA
For details on interfacing with the E

The 1000BASE-T physical layer IC can also be accessed via the 2-wire serial bus at
address ACh. For details interfacing with the PHY IC, see Marvell data sheet titled
“Alaska Ultra 88E1111 Integrated Gigabit Ethernet Transceiver”
number MV-S100649-00).
