Our MMP-D keystone panels offer a variety of module inserts for multimedia applications. The RJ45 copper modules can be used as jack for installation cables as well as coupler for the use of pre-assembled patch cables. The fiber optic modules are coupler except for the ST/FC versions. These are available as simplex or duplex modules in different versions. Suitable HDMI or USB modules can be used for audio/video and data/power transmission. We offer a suitable dust cover for empty keystone inserts.
