25GBASE-ER: The Extreme 25GBASE-ER Optics modules support link lengths
of up to 40Km over a pair of Single mode fibers with duplex LC connectors.
25GBASE-ER requires the use of FEC.
Note: Customers should ensure that 25GBASE-ER receivers are protected from excessive
input optical power by adding additional optical attenuation if necessary. TX and RX
power levels are described for each module in the Optics compatibility website.
25G-DACP: Extreme SFP28 to SFP28 copper direct-attach cables are suitable
for very short links and oer a cost-eective way to establish a 25-Gigabit link
between 25G ports of Extreme platforms. Extreme currently oers 25G passive
copper cables in lengths of 0.5, 1, 3 and 5 meters. 25G-DACP 0.5m, 1m and 2m do
not require FEC; 3m and 5m cables require the use of FEC.
25G-AOC: Extreme SFP28 to SFP28 active optical cables are suitable for short
links and oer a cost-eective way to establish a 25-Gigabit link between 25G
ports of Extreme platforms. Extreme currently oers 25G active optical cables in
lengths of 10 and 20 meters. 25G-AOC requires the use of FEC.

20G SFP-DD DAC: Extreme SFP-DD to SFP-DD copper direct-attach cables
are suitable for very short links and oer a cost-eective way to establish a
20-Gigabit link between SFP-DD ports of Extreme’s 5420 platform. The SFP-DD
ports support 2xSFP+ data links in a single SFP-DD connector. Extreme currently
oers 20G SFP-DD-SFP-DD passive copper cables in lengths of 0.5, 1, 3 and
5 meters.
20G SFP-DD/SFP+ DAC Breakout: Extreme SFP-DD to 2xSFP+ copper direct-
attach breakout cables are suitable for very short links and oer a cost-eective
way to establish two 10-Gigabit links between an SFP-DD port of Extreme’s 5420
platform and 2 10-Gigabit SFP+ ports. Extreme currently oers 20G SFP-DD-
2xSFP+ passive copper cables in lengths of 1, 3 and 5 meters.
