... 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, “ ...
