Optical Module

1.25G 10km duplex lc SFP transceiver

Kev piav qhia

SFP transceivers yog kev ua haujlwm siab, cov nqi siv tau zoo txhawb cov ntaub ntawv-tus nqi ntawm 1.25Gbps thiab 10km kis nrug deb nrog SMF.

Cov transceivers yog sib xws nrog SFP Multi-Source Agreement (MSA) thiab SFF-8472. Yog xav paub ntxiv, thov xa mus rau SFP MSA thiab SFF-8472.
