1. INTRODUCTION
XFP Connector 788862-[ ] or XFP Connector
1367500-1 and Cage Assembly 1489951-1 are used
to interconnect XFP fiber optic or copper transceiver
modules to host printed circuit (pc) boards. The EMI/
dust cover is used to prevent contaminants from
entering the chassis and confine any EMI emissions
when the transceiver is not installed. See Figure 1.
In applications where heat dissipation is necessary, a
heat sink can be used. Choose a heat sink that meets
the need of the specific application. A sample of
available heat sinks for the cage assembly are shown
in Figure 2. These heat sinks are designed to be
attached to the cage assembly using a clip.

2. DESCRIPTION
Each connector contains right-angle surface mount
contacts and features a card entry slot that accepts
the 1.0±0.1-mm thick integrated circuit card housed in
the transceiver.
The cage assembly is a frame with compliant pins for
mounting onto the host pc board. The transceiver
locking latches hold the transceiver in place, and the
hard stop controls the insertion depth of the
transceiver. The cage assembly is designed to be
bezel mounted. The front flange provides a flat
surface to contact the EMI gasket (to be installed
onto the perimeter of the bezel cutout) and

3. ASSEMBLY PROCEDURE
1. Install the connector onto the host pc board
according to Application Specification 114-13096.
Refer to Figure 3. Solder the connector to the
board before seating the cage assembly.
CAUTION
!
The soldering process will cause damage to the
cage assembly.
2. Design a pc board support fixture having a flat
surface with holes or a channel wide and deep
enough to receive any protruding components
during seating of the cage assembly on the host
pc board.
