NGĀ WHAKAMĀRAMA
He tino mahi ngā whakawhiti raraunga SFP, he iti te utu, ā, e tautoko ana i te tere raraunga o te 1.25Gbps me te tawhiti tuku 10KM me te SMF.
E toru ngā wāhanga o te taputapu whakawhiti: he taputapu whakawhiti taiaho FP, he pūoro whakaahua PIN kua whakauruhia ki te kaiwhakakaha mua-whakapūmau trans-impedance (TIA) me te wae whakahaere MCU. E tutuki ana i ngā kōwae katoa ngā whakaritenga haumaru taiaho akomanga I.
E hototahi ana ngā whakawhiti raraunga ki te Whakaaetanga Pūtake Maha SFP (MSA) me te SFF-8472. Mō ētahi atu kōrero, tirohia te SFP MSA.
