Finisar’s FCLF8520P2BTL, FCLF8521P2BTL and FCLF8522P2BTL 1000BASE-T Copper Small
Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA)1. They
are compatible with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE Std
802.32. The transceiver is RoHS compliant and per Directive 2011/65/EU3 and Finisar Application
Note AN-2038. The 1000BASE-T physical layer IC (PHY) can be accessed via I2C, allowing
access to all PHY settings and features.
The FCLF8520P2BTL uses the SFP’s RX_LOS pin for link indication, and 1000BASE-X auto-
negotiation should be disabled on the host system. The FCLF8521P2BTL 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 FCLF8522 shall support both RX_LOS pin for link
indication and 1000BASE-X auto-negotiation.

Notes:
1. Clock tolerance is +/- 50 ppm
2. By default, the FCLF8520P2BTL, FCLF8521P2BTL and FCLF8522P2BTL are full duplex
devices 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 FCLF8520P2BTL, FCLF8521P2BTL and FCLF8522P2BTL have an industrial temperature
ranges from -40°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 MSA1.
These SFPs use an Atmel AT24C01A 128 byte E2PROM with an address of A0h. For details on
interfacing with the E2PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire
Serial CMOS E2PROM.”4
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”5 (Marvell document number MV-S100649-00).

VIII. Mechanical Specifications
The host-side of the FCLF8520P2BTL, FCLF8521P2BTL and FCLF8522P2BTL conforms to the
mechanical specifications outlined in the SFP MSA1. The front portion of the SFP (part extending
beyond the face plate of the host) is larger to accommodate the RJ-45 connector. See Figure 2
below for details.
