Power Line carrier communication (PLCC) is a communication technology in which HV power line is used as media for telecommunication using RF carrier in the range of 100 to 500 kHz. The 4 kHz AF bandwidth of PLCC carries a 2 kHz speech channel and a super imposed FSK data signal.

OPTCL like any other power utilities or State Electricity Boards, has provision for PLCC in each and every 132kV/220kV/ 400kV line sections. It provides reliable, economic and dependable communication, proven over years. OPTCL procured PLCC terminals from different vendors like ABB,WSTL,BPL and PUNCOM.

Since " future is fibre" Transmission companies world wide have been replacing their conventional ground wire by specially designed aluminum embedded overhead FO cables called OPGW. It is believed that Power Utilities can gather revenue by leasing the spare capacity of their intercity OPGW route to broadband operators. It is preferred over buried OFC due to least chances of cut and theft . OPTCL has laid 550 kM of 8 fibre OPGW from Jaya Nagar to Bhubaneswar. The SDH equipments installed are Alcatel 1650SMC operating at STM-1 level.
