FEATURES AND SPECIFICATIONS
Molex’s XPAK Guide Rail With Enhanced, Multiple Electromagnetic
Interference (EMI) Gaskets Provide Superior EMI Protection
XPAK represents the new 10 Gigabit Small Form-factor Pluggable system of modules
and interconnects that convert serial electrical signals to external serial optical or
electrical signals. The system includes a Multi-Source Agreement (MSA) standard
pluggable module and rail hardware. The technoloy is designed to support 10 Gigabit
Fibre Channel, 10 Gigabit Ethernet, OC192/STM-64 and InfiniBand* protocols.
The XPAK guide rail aligns Molex’s 10Gbps CX4 copper module (in development) or
any MSA optical transceiver with the 70-circuit XPAK host connector (74441-0013).
The guide rail features a passive latch point and a hard stop to control the insertion
depth of the module. The rail assembly features two EMI gaskets: front and lower rear.
These gaskets are designed to reduce emissions eminating from the equipment.
Molex designed the XPAK rail to meet XPAK MSA standards. The optical interface is a
XPAK optical transceiver which interfaces with Molex SC cables (Series 86282).
To remain competitive, Molex offers rails and cages for pluggable systems in multiple
form-factors. The difference between a “rail” and a “cage” is the following:
-Rail: an enclosure that holds a module
-Cage: an enclosure that completely covers a module
