Welcome to X2MSA.org
"X2" is a new multi-source agreement (MSA) supported by eight (and growing) leading
networking component suppliers listed in the "Membership Information" page (click tab
above) of this web site.
X2 defines a smaller form-factor 10 Gb/s pluggable fiber optic transceiver optimized
for 802.3ae Ethernet, ANSI/ITUT OC192/STM- 64 SONET/SDH interfaces, ITUT G.709, OIF OC192
VSR, INCITS/ANSI 10GFC (10 Gigabit Fibre Channel) and other 10 Gigabit applications.
X2 is initially focused on optical links to 10 kilometers and is ideally suited for
Ethernet, Fibre Channel and telecom switches and standard PCI (peripheral component
interconnect) based server and storage connections, where a "half size" XENPAK optical
transceiver is desired.
X2 is physically smaller than XENPAK but maintains the mature electrical I/O
specification defined by the XENPAK MSA and continues to provide robust thermal
performance and electromagnetic shielding.
The X2 optical platform has been designed so that the heat sink and front bezel can
be easily adapted to the different needs of the key 10 Gb markets. X2 can be mounted on
the front panel, mid board, or in a conventional PCI card. X2's flexibility to address a
wide range of high-bandwidth applications is expected to drive higher volumes on this one
platform, thereby leading to lower optics costs.
Electrically, X2 is compatible with the XENPAK MSA. X2 uses the same Tyco
Electronics-designed, 70-pin electrical connector as XENPAK supporting four wire
XAUI (10-gigabit attachment unit interface). X2 also will support the OIF SFI4_P2
interfaces and serial electrical interfaces as they emerge.
The MSA and Operating guidelines will be published on the "MSA" page (click tab above)
of this web site.
The MSA first draft is now available on the MSA page.
