MRJ21 Patch Panel

The MRJ21 Patch Panel is a high density cabling device which transitions MRJ21 connectivity into traditional RJ45 ports. The demand for this product arises out of the fact that the MRJ21 connector is a high density 24 pair connector used on new networking and telecommunications equipment. Very often, this new equipment must interface with existing infrastructure which consists of RJ45 connectivity, and the MRJ21 patch panel allows for an organized transition point for this interface. The product can also be used in conjunction with MRJ21 cable assemblies to create high density, low profile, pre-terminated Category 5e permanent links. The product is available in 48 port versions for Gigabit Ethernet and 10/100 Base-T which fit into a standard 19” rack.
