Extreme Networks Data Sheet XENPAK 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. The XENPAK pluggable interface is an industry standard or Multisource Agreement (MSA) for pluggable 10 Gigabit Ethernet Optics. 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. Features Target Applications LR XENPAK LR XENPAK • 10GBASE-LR transceivers support a link length of up to 10 kilometers on standard 1310 nm single-mode fiber (SMF) • Most commonly deployed in inter-building single mode connections. ER XENPAK ER XENPAK • ER XENPAK module supports distances of up to 40 km on 1550 nm SMF SR XENPAK • SR XENPAK module supports distances of up to 300 m on 850 nm multimode fiber (MMF) ZR XENPAK • ZR XENPAK provides convenient long haul 10 Gigabit Ethernet connectivity for distances up to 80 km on 1550 nm SMF LX4 XENPAK • 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 • 10GBASE-ER transceivers are used by Ethernet service providers for inter-PoP connectivity. SR XENPAK • 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. ZR XENPAK • For long-reach service provider interconnect and metro Ethernet rings. LX4 XENPAK • Provides network administrators the flexibility to use the same XENPAK for intra-building multimode (including FDDI grade MMF) and inter-building single-mode connections.
