He aha ka ʻokoʻa ma waena o ka singlemode a me ka multimode fiber?

ʻO ka ʻokoʻa nui ma waena o kauwea fiber opticalAia ka Singlemode a me ka multimode i ke ala o ka lawe ʻana i ka mālamalama a me ka mamao e hiki ai iā lākou ke hoʻouna pono i ka ʻikepili.

ʻO kafiber mode hoʻokahi Hoʻolālā ʻia ia e lawe i hoʻokahi ʻano o ka māmā, e ʻae iā ia e hoʻouna i ka ʻikepili ma nā mamao lōʻihi me ka liʻiliʻi o ka hōʻailona hōʻailona. ʻOi aku ka liʻiliʻi liʻiliʻi (maʻamau 9 microns) a e hana ana ma kahi hawewe nalu o 1310 nm a i ʻole 1550 nm. Hoʻohana mau ʻia ka fiber mode hoʻokahi i nā kelepona lōʻihi, e like me nā pūnaewele kelepona a me nā ʻoihana pūnaewele.

Ma ka ʻaoʻao ʻē aʻe, ua hoʻolālā ʻia ka fiber multimode e lawe i nā ʻano māmā he nui, e hopena i ka hoʻopuehu nui ʻana o ka hōʻailona kukui. Loaʻa iā ia ka nui kumu nui (maʻamau 50 a i ʻole 62.5 microns) a hana ma kahi hawewe o 850 nm a i ʻole 1300 nm. He kūpono ka multimode fiber no nā mamao pōkole, e like me loko o nā hale a i ʻole nā ​​pā kula, a hoʻohana maʻamau no nā noi leo a me ka ʻikepili.

ʻO ka hōʻuluʻulu manaʻo, ʻo nā ʻokoʻa nui ma waena o nā uwea fiber optic mode hoʻokahi a me multimode ʻo ia ka nui o ka nui, ka mamao e hiki ai iā lākou ke hoʻouna pono i ka ʻikepili, a me nā noi i kūpono loa lākou.
