Each connector is a housing with right--angle surface mount contacts. The connector features an embossed “1”
for Pin 1 identification, a chamfered corner for orientation, alignment posts that provide stability for placement
on the pc board, standoffs to allow easy pc board cleaning after soldering, and a card entry slot that accepts a
1.0+
0.1 mm thick integrated circuit card housed in the transceiver module.
Each cage assembly is a frame with compliant pin contacts; available with or without electromagnetic
interference (EMI) suppression pins. The cage assembly features thermal vent holes, a locking latch for
holding the mating transceiver module in place, kick--out spring to release the transceiver module for removal,
and panel grounding features (panel ground springs and elastomeric gasket) to provide electrical contact to the
bezel. The dust cover (SFP cage assemblies) or the EMI plug assembly (SFP+ cage assemblies)—one for
each port—is used when the transceiver module is not mated to the cage assembly to prevent contaminants
from entering the chassis.
The SFP+ cage assembly is available in two versions: elastomeric gasket, and external EMI panel ground
springs (springs are on the outside of the cage assembly). The elastomeric gasket cage assembly is available
in ganged only. The external EMI panel ground springs cage assembly is available in single port and ganged
(1¢2, 1¢4, and 1¢6). Both versions are available with or without light pipes.
