Khoom Paub meej
D-net's 40G QSFP + ER4 40KM transceiver module yog tsim los ua raws li QSFP Multi-Source Agreement (MSA) raws li nws daim ntawv cog lus, kev sib txuas kho qhov muag / hluav taws xob, thiab kev kuaj xyuas digital interface. QSFP no+ 40G 40KM module ua haujlwm siv ib zaug +3.3V fais fab mov thiab suav nrog kev tswj hwm thoob ntiaj teb xws li Module Present, Rov Pib dua, cuam tshuam, thiab Tsawg Fais Fab Hom, uas yog sib xws nrog LVCMOS / LVTTL cov qauv . Txhawm rau txhim kho qhov muag pom kev cuam tshuam hauv lub tshuab ntev ntev, 40G QSFP + ER4 40KM transceiver module xav tau kev siv ib hom fiber ntau (SMF).
