Whakaahuatanga Poto:

Ko te Mylinking™ RoHS Compliant 1.25Gbps 1310nm Optical Transceiver 10km Reach he kōwae mahi-teitei, he utu-pai hoki e tautoko ana i te tere raraunga rua o te 1.25Gbps/1.0625Gbps me te tawhiti tuku 10km me te SMF. E toru ngā wāhanga o te transceiver: he transmitter FP laser, he photodiode PIN kua whakauruhia ki te trans-impedance preamplifier (TIA) me te waeine whakahaere MCU. Ka tutuki i ngā kōwae katoa ngā whakaritenga haumaru laser akomanga I. Ka hototahi ngā transceiver ki te SFP Multi-Source Agreement (MSA) me te SFF-8472. Mō ētahi atu kōrero, tirohia te SFP MSA.
