    Pehea e ʻike ai inā he ʻano hoʻokahi a i ʻole multi-mode ka module fiber optical?

    Ka manawa hoʻouna: Jan-27-2021

    Ma ke ʻano he ʻāpana koʻikoʻi o ka hoʻoili ʻana o ka pūnaewele optical, hana ʻia nā module fiber optical e like me ka hoʻololi photoelectric, i hiki ke hoʻouna ʻia nā hōʻailona i nā fiber optical. No laila, ʻike ʻoe pehea e hoʻokaʻawale ai inā heʻO ka module fiber optical he ʻano hoʻokahia i ʻole ke ʻano he nui? Eia kekahi mau ala e hoʻokaʻawale ai i waena o nā modula fiber mode multi-mode a me nā modula fiber mode single-mode.

    ʻO ka mea mua, hiki iā mākou ke nānā i nā palena hawewe o ka module fiber optical. ʻO ka maʻamau, ʻo 850nm ka lōʻihi hawewe o ka module fiber optical, a ʻo ka module fiber optical he multimode optical fiber module. ʻO ka lōʻihi o ka nalu o ka module fiber optical mode hoʻokahi he 1310nm, 1330nm, 1490nm, 1550nm, a me nā mea'ē aʻe.

    ʻO ka lua, hiki iā mākou ke nānā i ka mamao o ka lawe ʻana i nā modula fiber optic. ʻO ka mamao o ka hoʻouna ʻana o nā modula fiber optic multimode ma lalo o 2km, pono e hoʻohana ʻia me nā multimode fiber jumpers. ʻO ka mamao o ka hoʻouna ʻana o kahi module fiber optical mode hoʻokahi ma luna o 2km, hiki i kahi modula fiber optical mode Gigabit hoʻokahi ke hoʻouna a hiki i 160km, a hiki i ka 10-Gigabit single-mode fiber optical module ke hoʻouna a hiki i 100km.

    ʻO ke kolu, hiki iā mākou ke nānā i nā ʻano o nā ʻāpana optical o ka module fiber optic. ʻO ka mea uila uila o ka multimode fiber optic module ʻo VCSEL, a ʻo ka mea hoʻopuka kukui o ka module fiber optic mode hoʻokahi ʻo DFB, EML, FP, etc.

    ʻEhā, hiki iā mākou ke hoʻokolokolo i ke ʻano hoʻokahi a i ʻole multi-mode mai ke kala o ke apo huki o ka module fiber optic. ʻO ke kala o ke apo huki o ka multimode fiber optic module me ka liʻiliʻi o ka lawe ʻana ma lalo o 40G (koe ʻole 40G) ʻeleʻele maʻamau, 40G a ma luna (me 40G) ʻO ke kala o ke apo huki o ka module fiber optic multimode he beige. ʻO ke apo huki o ka module fiber mode hoʻokahi me ka nalu o 1310nm he uliuli. Eia kekahi, aia nā kala ʻē aʻe o ke apo huki. ʻO lākou a pau nā modula fiber mode hoʻokahi.

    ʻIke i ke ʻano fiber (single-mode/ʻano ʻano nui) o ka module fiber optic e kōkua iā mākou e koho pono i ka lele lele pili.
