Patch panel math

• one shelf of patch panel = • 8 12-packs of fibers = total of 96 fibers• 1 RM = 6 fibers, • 1 RBX=4*RM = 24 fibers,• 4 RBXes = 4*24 fibers = 96 fibers• 6 HTRs = 6*16 fibers = 96 fibers• one shelf can handle 4 RBXes=>6 HTRs• Basic unit: two 20 deg wedges of HBHE • For example: w14+w15 (for mtcc)
