Molex’s 70-pin Z-Axis Pluggable host connector
extends an already complete line of Small FormFactor 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.
The 70-pin host connector features SMT leads in
an edge-card configuration and is part of the ZAxis Pluggable family of products. The connector
provides a compact, high bandwidth interface to
support the emerging XAUI ("zowie") data transfer
protocol.
