114 - 13219 rev c 6 of 10 3.7. transceiver modules caution the mating transceiver module packing size cannot exceed the width of each cage port opening. this includes the part of the transceiver that is extending outside the cage. since the port - to - port spacing has a 14.25 mm centerline, the widest transceiver width extending outside of the cage should be less than 14 mm. this will prevent any possible interference when transceivers are inserted in adjacent ports. 3.8. bezel caution it is strongly recommended that this bezel configuration not be used in pci applications. the following requir ements were intended to be used in the communications industry only. a. thickness the bezel thickness range shall be 0.8 through 2.6 mm. b. cutout the bezel must provide a cutout that allows proper mounting of the connector and cage assembly. the cage assembly panel grounding feature must be compressed by the bezel in order to provide an electrical groun d between the connector and cage assembly and bezel for emi suppression. care must be used to avoid interference between adjacent connector and cage assemblies and other components. the minimum allowable distance between connector and cage assemblies must be considered to ensure proper assembly. dimensions for bezel cutout and minimum allowable distance between cutouts are shown in figure 4. connector and cage assy dimension (0.1) type configuration a b (min) c d (ref) spring fingers gasket spring fingers gasket standard 2x1 15.45 16.25 19.5 26 26 26 2x2 29.7 31 34.25 26 26 26 2x4 58.2 59.5 62.75 26 26 26 2x5 72.45 73.75 77 26 26 26 2x6 86.7 88 91.25 26 26 26 2x8 115.2 116.5 119.75 26 26 26 figure 4 note: not to scale recommended bezel cutout (minimum pitch) and pc board and bezel position bezel thickness: 0.8 - 2.6 mm section y - y 0.30 maximum radius (4 places) a y y c d (ref) b (min) pc board cutout centerline to cutout centerline cutout in bezel 3.50 0.30 (distance between back of bezel and front of pc board) pc board 0 0.1 (bottom of cutout in bezel to top of pc board)
