Finisar’s FCM-8520/8521-3 1000BASE-T Copper GBIC transceivers are based on the
GBIC Specification Revision 5.5
1
. They are compatible with the Gigabit Ethernet and
1000BASE-T standards as specified in IEEE Std 802.3z
2
and IEEE Std 802.3ab
3
.
The FCM-8520-3 uses the GBIC’s RX_LOS pin for link indication, and 1000BASE-X
auto-negotiation must be disabled on the host system. The FCM-8521-3 is compatible
with 1000BASE-X auto-negotiation, but does not have a link indication feature
(RX_LOS is internally grounded). See AN-2032, “Commonly Asked Questions
Regarding Auto-negotiation on Finisar’s 1000BASE-T GBICs”

, for a more complete
explanation on the differences between the two models.
