Optical module

1.25Gbps 550m Duplex LC SFP Transceiver

Kufotokozera

Ndife okondwa kuwonetsa ma module apamwamba kwambiri, otsika mtengo a SFP opangidwa kuti azithandizira mitengo ya data ya 1.25Gbps ndi mtunda wotumizira wa 550 metres pa multimode fiber (MMF). Transceiver imagwirizana kwathunthu ndi SFP Multi-Source Agreement (MSA) ndi SFF-8472 miyezo. Kuti mumve zambiri, onani zolemba za SFP MSA ndi SFF-8472.

Tikukhulupirira kuti ma module athu owoneka bwino a SFP akumana ndikupitilira zomwe mukuyembekezera pakuchita komanso kudalirika. Ngati muli ndi mafunso kapena mukufuna kukambirana zomwe mukufuna, chonde omasuka kulankhula nafe.

Zikomo poganizira malonda athu.
