Finisar's 1000BASE-T Copper SFP transceivers enable system designers to design flexibility into their ports. These transceivers can be populated into optical SFP slots enabling an optical Ethernet port (1000Base-X) to be converted into a copper Ethernet port (1000Base-T) either in the field or in production. This simplifies designs and increases manufacturing efficiency through reduced component count.

The FCMJ-8521-3/8520-3 are compatible with Gigabit Ethernet and 1000BASE-T standards. For more information, see AN-2036 "Frequently Asked Questions Regarding Finisar's 1000Base-T SFP (FCMJ-8521-3/8520-3)".
