Kōwae Whakawhitiwhiti Whatu Mylinking™ SFP LC-MM 850nm 550m

ML-SFP-MX 1.25Gbps SFP 850nm 550m LC Aratau-Maha

Whakaahuatanga Poto:

Ko te Mylinking™ RoHS Compliant 1.25Gbps 850nm Optical Transceiver 550m Reach he kōwae mahi-teitei, utu-pai hoki e tautoko ana i te tere raraunga o te 1.25Gbps me te tawhiti tuku 550m me te MMF. E toru ngā wāhanga o te transceiver: he transmitter laser VCSEL, 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.
