Optical Module

1.25Gbps 550m Duplex LC SFP Transceiver

Kev piav qhia

Peb txaus siab los qhia cov khoom lag luam zoo, pheej yig SFP optical modules tsim los txhawb cov ntaub ntawv tus nqi ntawm 1.25Gbps thiab kis tau tus mob ntawm 550 meters hla multimode fiber ntau (MMF). Lub transceiver tau ua tiav nrog SFP Multi-Source Agreement (MSA) thiab SFF-8472 tus qauv. Yog xav paub ntxiv, saib cov ntaub ntawv SFP MSA thiab SFF-8472.

Peb ntseeg tias peb SFP optical modules yuav ua tau raws li koj qhov kev cia siab rau kev ua tau zoo thiab kev ntseeg tau. Yog tias koj muaj lus nug lossis xav tham txog koj cov kev xav tau tshwj xeeb, thov hu rau peb.

Ua tsaug rau koj xav txog peb cov khoom.
