Extreme networks LX4 XENPAK 10114 Datenbogen

The IEEE 802.3ae committee ratified the 10 
Gigabit Ethernet standard and along with the 
general specification, defined a number of fiber 
optic interfaces. These standard interfaces 
attempted to satisfy a number of different 
objectives including support for MMF and SMF 
compatibility. 

XENPAK (www.xenpak.org) is the most mature 
and widely deployed of the various 10 Gigabit 
Ethernet MSAs. It is the only MSA that can 
support all Gigabit Ethernet standard interfaces 
and hence is the MSA of choice for Ethernet 
switch vendors.

 

10GBASE-LR transceivers support a link length of up to        
10 kilometers on standard 1310 nm single-mode fiber (SMF) 

ER XENPAK module supports distances of up to 40 km on 
1550 nm SMF

SR XENPAK module supports distances of up to 300 m          
on 850 nm multimode fiber (MMF)

ZR XENPAK provides convenient long haul 10 Gigabit         
Ethernet connectivity for distances up to 80 km on              
1550 nm SMF

LX4 XENPAK is a single-mode, 1310 nm, 10 Gigabit Ethernet 
WWDM XENPAK transceiver provides convenient 10 Gigabit 
Ethernet connectivity for distances up to 300 m on MMF and 
up to 10 km on SMF

Most commonly deployed in inter-building 
single mode connections.

10GBASE-ER transceivers are used by Ethernet 
service providers for inter-PoP connectivity.

10GBASE-SR transceivers are used in a data 
center to interconnect two Ethernet switches or 
to link an end-device (e.g. 10 Gigabit Ethernet 
servers or NAS device) to an Ethernet switch.

For long-reach service provider interconnect and 
metro Ethernet rings.

Provides network administrators the flexibility to 
use the same XENPAK for intra-building 
multimode (including FDDI grade MMF) and 
inter-building single-mode connections.
