Abstract: A modular jack assembly for mounting to a printed circuit board, is shown comprising a plurality of modular jacks assembled to a common integral housing and disposed in back-to-back mirror image symmetry. Shielding, is provided around the connector assembly and shielding between the two rows is also provided for suppressing cross-talk therebetween. The design is compact, providing for a large number of ports without increasing the length of the connector assembly, whilst also providing good access to the resilient locking latches of complementary modular plugs received by the jacks.
