For applications using ganged cage assemblies, the top surface of the Transceiver Module is to be free of EMI bumps and maintain a flatness of 0.08 mm. The width of the mating transceiver module (portion outside of the cage assembly) cannot exceed the width of the port of the cage assembly. This will prevent any possible interference between ports when inserting the transceiver modules. Port-to-port centerline spacing is 14.25 mm; therefore, the maximum width of the transceiver (outside of the cage assembly) cannot exceed 14 mm
