40GBASE-SR4: The Extreme 40GBASE-SR4 Optics modules support link
lengths of up to 100m (OM3) or 150m (OM4) over Multimode Fiber with MPO-12
connectors. They provide 40G optical links over 12-fiber parallel fiber terminated
with MPO connectors.
Note: 40G-SR4-QSFP150M and AA1404005-E6 are compatible with 10GBASE-SR,
allowing for break-out to 10GBASE-SR transceivers.
40GBASE-BDSR: The Extreme 40GBASE-BDSR Optics modules support link
lengths of up to 100m (OM3), 150m (OM4) or 200m (OM5) over Multimode
Fiber with LC connectors. They provide 40G optical links over 2 Multimode fibers
by transmitting and receiving 20Gb streams bidirectionally over each fiber at
dierent wavelengths centered at 850nm and 900nm for TX and RX on each fiber.
40GBASE-ESR4: The Extreme 40GBASE-ESR4 Optics modules support link
lengths of up to 300m (OM3) or 400m (OM4) over Multimode Fiber with MPO-12
connectors. They provide 40G optical links over 12-fiber parallel fiber terminated
with MPO connectors.
Note: 40G-ESR4-QSFP400M-NT is compatible with 10GBASE-SR, allowing break-out to
four 10GBASE-SR connections.
40GBASE-LM4: The Extreme 40GBASE-LM4 Optics modules support link
lengths of up to 140m (OM3) or 160m (OM3) over Multimode Fiber with MPO-12
connectors, or up to 1Km over Single mode fiber with duplex LC connectors. The
40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and
demultiplexing of the four wavelengths are managed within the device.
40GBASE-LR4: The Extreme 40GBASE-LR4 Optics modules support link lengths
of up to 10Km over a pair of Single mode fibers with duplex LC connectors. The
40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and
demultiplexing of the four wavelengths are managed within the device.
40GBASE-PSM4: The Extreme 40GBASE-PSM4 Optics modules support link
lengths of up to 10Km over Single mode fibers with MPO-12 connectors. They
provide 40G optical links over 12-fiber parallel fiber terminated with MPO
connectors. 40GBASE-PSM4 does not require the use of FEC.
Note: 10326 and 40G-QSFP-LR4-INT are compatible with 10GBASE-LR, allowing for
break-out to 10GBASE-LR transceivers.
40GBASE-ER4: The Extreme 40GBASE-ER4 Optics modules support link lengths
of up to 40Km over a pair of Single mode fibers with duplex LC connectors. The
40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and
demultiplexing of the four wavelengths are managed within the device.
Note: Customers should ensure that 40GBASE-ER4 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.
40G-DACP: Extreme QSFP+ to QSFP+ copper direct-attach 40G cables
are suitable for very short links and oer a cost-eective way to establish a
40-Gigabit link between 40G ports of Extreme platforms. Extreme currently
oers 40G passive copper cables in lengths of 0.5, 1, 3 and 5 meters.
40G-DACP Breakout: Extreme QSFP+ to 4xSFP+ copper direct-attach 40G
break-out cables are suitable for very short links and oer a cost-eective way
to establish a 40G-Gigabit link between one 40G QSFP+ port and four 10G SFP+
ports of Extreme platforms. Extreme currently oers 40G passive copper break-
out cables in lengths of 1, 2, 3 and 5 meters.
