Sistem pengaitan ( coupling system) diklasifikasikan menurut pengaitan induktip dan pengaitan kapasitip. Karena jebakan saluran (line trap) merupakan impedansi tinggi terhadap frekuensi pembawa, maka jebakan ini diserikan dengan saluran transmisi tenaga guna memperbaiki karakteristik penyaluran gelombang-gelombang pembawa. Pengaitan induktip lewat udara menggunakan penghantar yang dipasang sejajar dan dengan jarak tertentu dari saluran transmisi; sistem ini dipakai untuk mengaitkan peralatan PLC ...
