100GBASE-4WDM-40: The Extreme 100GBASE-4WDM-40 Optics modules
support link lengths of up to 40Km over a pair of Single mode fibers with duplex
LC connectors. The 100 Gigabit Ethernet signal is carried over four wavelengths
using LAN-WDM wavelengths. Multiplexing and demultiplexing of the four
wavelengths are managed within the device. 100GBASE-4WDM-40 requires the
use of FEC.
Notes:
1. 100GBASE-4WDM-40 is compatible with 100G-ER4-QSFP40KM up to 40Km using FEC,
and with 100GBASE-4WDM-20 up to 20Km using FEC.
2. 100GBASE-4WDM-40 is not compatible with 100GBASE-4WDM-10 or 100GBASE-
CWDM4.
Customers should ensure that 100GBASE-4WDM40 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.
100GBASE-ER4LT: The Extreme 100GBASE-ER4 Optics modules support
link lengths of up to 40Km over a pair of Single mode fibers with duplex LC
connectors. The 100 Gigabit Ethernet signal is carried over four wavelengths
using LAN-WDM wavelengths. Multiplexing and demultiplexing of the four
wavelengths are managed within the device. Full 40km reach requires the use of
FEC on the host platform. Without FEC, the reach is 30km.
Notes:
1. 100G-ER4-QSFP40KM is compatible with 100GBASE-LR4 modules up to 10Km without
using FEC.
2. 100G-ER4-QSFP40KM is compatible with 100G-4WDM-QSFP40KM up to 40KM using
FEC, and with 100G-4WDM-QSFP20KM up to 20Km using FEC.
Customers should ensure that 100GBASE-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.
100G-DACP: Extreme QSFP28 to QSFP28 copper direct-attach 100G-DACP
cables are suitable for very short links and oer a cost-eective way to establish
a 100-Gigabit link between 100G ports of Extreme platforms. Extreme currently
oers passive copper cables in lengths of 0.5, 1, 3 and 5 meters. 100GBASE-
DACP requires the use of FEC.
100G-DACP Breakout: Extreme QSFP28 to 4xSFP28 copper direct-attach
100G-DACP break-out cables are suitable for very short links and oer a cost-
eective way to establish a 100-Gigabit link between one 100G QSFP28 port
and four 25G SFP28 ports of Extreme platforms. Extreme currently oers
passive copper break-out cables in lengths of 1, 3 and 5 meters. 100GBASE-DACP
Breakout requires the use of FEC.
100G-AOC: Extreme QSFP28 to QSFP28 active optical fiber cables are suitable
for short links and oer a cost-eective way to establish a 100-Gigabit link
between 100G ports of Extreme platforms. Extreme currently oers active
optical cables in lengths of 5, 7. 10 and 20 meters.
100G-AOC Breakout: Extreme QSFP28 to 4xSFP28 active optical fiber cables are
suitable for short links and oer a cost-eective way to establish a 100-Gigabit link
between one 100G port and four 25G SFP28 ports of Extreme platforms. Extreme
currently oers active optical breakout cables in lengths of 10 and 20 meters.
