Nhanganyaya
SRB series optical receiver inogamuchira optical yemukati yakagadzirwa kuti ienderane nechirongwa chekugadzirisa network fiber. Chigadzirwa ichi chine ma RF output ports 1 kusvika 2. Uye isa optical AGC function kana +2dBm ~ -6dBm kana uchigamuchira output inogona kuchengetwa pa106dBµV pamusoro (mbiri); goko uchishandisa cast aluminium shell.
