The power consumption of the former is less than 4.5W, and the advantage of the FEC coding function is to improve the sensitivity of transmission; while the power consumption of the latter without FEC function is less than 3.5W.
Ukusetshenziswa kwamandla kwangaphambili kungaphansi kwe-4.5W, futhi inzuzo yomsebenzi wokukhishwa kwe-FEC ukuthuthukisa ubuzwe bokudluliselwa; kuyilapho ukusetshenziswa kwamandla okugcina ngaphandle komsebenzi we-FEC kungaphansi kwe-3.5W.
