Pluggable Host Connector

for 10-Gigabit Transceivers

Molex’s 70-pin Z-Axis Pluggable host connector The 70-pin host connector features SMT leads in (WAN), metropolitan area networks (MAN), and

extends an already complete line of Small Form- an edge-card configuration and is part of the Z- local area networks (LAN).

Factor Pluggable (SFP) products. This connector

enables the use of emerging 10-Gigabit pluggable

transceivers for horizontal front panel access. It

conforms to the host board layout as defined in

the XENPAK and XGP Multi-source Agreements

(MSA) and supports the 10-Gigabit Ethernet IEEE

802.3ae standard.

Axis Pluggable family of products. The connector

provides a compact, high bandwidth interface to

support the emerging XAUI ("zowie") data transfer

protocol.

XAUI, an acronym for 10-Gigabit Attachment Unit

Interface, is the architecture proposed for 10-

Gigabit Ethernet in the IEEE 802.3ae standard. The

Initial implementations will utilize a standard SC

duplex fiber optic connector and will be compliant

with IEEE 802.3 mediums such as 850 nm serial,

850 nm coarse wavelength division multiplexing

(CWDM), 1310 nm serial , 1310 nm CWDM, and

1550 nm serial transceiver applications.

MSAs provide plug-and-play interoperability

XAUI interface defines four different channels,
