Kodi Outdoor Optical Cable ndi chiyani?
Chingwe chakunja cha kuwala ndi mtundu wa chingwe cha optical fiber chomwe chimagwiritsidwa ntchito potumiza mauthenga. Imakhala ndi chitetezo chowonjezera chomwe chimatchedwa zida zankhondo kapena chitsulo, chomwe chimapereka chitetezo chakuthupi ku ulusi wamaso, kuwapangitsa kukhala olimba komanso okhoza kugwira ntchito m'malo ovuta.
Kusiyana kwakukulu pakati pa G652D ndi G657A2 single-mode ulusi ndi motere:
1 Kupindika Magwiridwe
Ulusi wa G657A2 umapereka magwiridwe antchito apamwamba kwambiri poyerekeza ndi ulusi wa G652D. Amapangidwa kuti azitha kupirira ma bend radii, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito pamanetiweki ofikira ma kilomita omaliza pomwe kukhazikitsa ulusi kumatha kukhala ndi makona akuthwa ndi ngodya.
2 Kugwirizana
Ulusi wa G652D ndi wobwerera m'mbuyo umagwirizana ndi makina akale, zomwe zimawapangitsa kukhala chisankho chokondedwa pakukweza maukonde ndikuyika komwe kumagwirizana ndi zida zoyambira ndikofunikira. Komano, ma fiber a G657A2 angafunike kuganizira mozama za zomangamanga zomwe zilipo musanatumizidwe.
3 Mapulogalamu
Chifukwa cha kupindika kwawo kwapamwamba, ulusi wa G657A2 ndi wabwino kuti ugwiritsidwe ntchito mu Fiber-to-the-Home (FTTH) ndi Fiber-to-the-Building (FTTB), kumene ulusi umafunika kuyenda m'malo olimba ndi ngodya. Ulusi wa G652D umagwiritsidwa ntchito nthawi zambiri pama netiweki amsana wautali komanso maukonde am'mizinda yayikulu.
Mwachidule, ma fiber a G652D ndi G657A2 a single-mode ali ndi maubwino awo ndi ntchito zawo. G652D imapereka kuyanjana kwabwino kwambiri ndi machitidwe oyambira ndipo ndiyoyenera maukonde akutali. Kumbali inayi, G657A2 imapereka magwiridwe antchito abwinoko, ndikupangitsa kuti ikhale chisankho chokondedwa cha ma netiweki ndi makhazikitsidwe okhala ndi zofunikira zopindika. Kusankha mtundu wa ulusi woyenera kumatengera zosowa zenizeni za netiweki ndi zomwe mukufuna kugwiritsa ntchito.
