Kōwae Optical

1.25Gbps 550m Duplex LC SFP Transceiver

Whakaahuatanga

E harikoa ana matou ki te whakauru i nga waahanga whakaata SFP kounga teitei, utu utu i hangaia hei tautoko i nga reiti raraunga o te 1.25Gbps me nga tawhiti tuku o te 550 mita i runga i te muka multimode (MMF). Ko te transceiver he tino hototahi ki te SFP Multi-Source Agreement (MSA) me nga paerewa SFF-8472. Mo etahi atu korero, tirohia nga tuhinga SFP MSA me SFF-8472.

E whakapono ana matou ka tutuki a maatau waahanga matakite SFP ka nui ake i o tumanako mo te mahi me te pono. Mena kei a koe etahi patai, he hiahia ranei ki te korero mo o hiahia motuhake, tena koa waea mai ki a maatau.

Mauruuru koe mo te whakaaro ki a maatau hua.
