Mu zomangamanga za FTTx ndi PON, optical splitter imagwira ntchito yofunika kwambiri popanga ma network osiyanasiyana a point-to-multipoint filber optic. Koma kodi mukudziwa kuti fiber optic splitter ndi chiyani? Ndipotu, fiber opticspliter ndi chipangizo chopanda kuwala chomwe chingagawanitse kapena kulekanitsa kuwala kwadzidzidzi m'ma lightbeam awiri kapena kuposerapo. Mwachidule, pali mitundu iwiri ya fiber splitter yomwe imagawidwa malinga ndi mfundo yawo yogwirira ntchito: fused biconicaltaper splitter (FBT splitter) ndi planar lightwave circuit splitter (PLC splitter). Mutha kukhala ndi funso limodzi: kodi kusiyana pakati pawo ndi kotani ndipo kodi tigwiritse ntchito FBT kapena PLC splitter?
Kodi ndi chiyaniChigawo cha FBT?
FBT splitter imachokera ku ukadaulo wachikhalidwe, womwe ndi mtundu waWopanda mphamvuKudina pa Netiweki, zomwe zimaphatikizapo kusakanikirana kwa ulusi wambiri kuchokera mbali ya ulusi uliwonse. Ulusiwu umalumikizidwa powatenthetsa pamalo ndi kutalika kwina. Chifukwa cha kufooka kwa ulusi wosakanikirana, umatetezedwa ndi chubu chagalasi chopangidwa ndi ufa wa epoxy ndi silika. Pambuyo pake, chubu chachitsulo chosapanga dzimbiri chimaphimba chubu chamkati chagalasi ndipo chimatsekedwa ndi silicon. Pamene ukadaulo ukupitilira kukula, mtundu wa ma splitter a FBT wakula kwambiri, zomwe zimapangitsa kuti akhale yankho lotsika mtengo. Tebulo lotsatirali likuwonetsa zabwino ndi zoyipa za ma splitter a FBT.

Kodi ndi chiyaniChigaŵa cha PLC?
Chigawo cha PLC chimapangidwa pogwiritsa ntchito ukadaulo wa planar lightwave circuit, womwe ndi mtundu waWopanda mphamvuKudina pa Netiweki. Ili ndi zigawo zitatu: substrate, waveguide, ndi chivindikiro. Waveguide imagwira ntchito yofunika kwambiri pakugawanitsa komwe kumalola kudutsa magawo enaake a kuwala. Chifukwa chake chizindikirocho chikhoza kugawidwa mofanana. Kuphatikiza apo, ma PLC splitter amapezeka m'mitundu yosiyanasiyana ya ma splitter, kuphatikiza 1:4, 1:8, 1:16, 1:32, 1:64, ndi zina zotero. Alinso ndi mitundu ingapo, monga bare PLC splitter, blockless PLC splitter, fanout PLC splitter, mini plug-in type PLC splitter, ndi zina zotero. Muthanso kuwona nkhani ya Kodi Mukudziwa Zambiri Zokhudza PLC Splitter? kuti mudziwe zambiri za PLC splitter. Tebulo lotsatirali likuwonetsa zabwino ndi zoyipa za PLC splitter.

FBT Splitter vs PLC Splitter: Kodi Kusiyana Ndi Chiyani?(Kuti mudziwe zambiri zaKodi pali kusiyana kotani pakati pa Passive Network Tap ndi Active Network Tap?)
1. Kutalika kwa Mafunde Ogwira Ntchito
Chigawo cha FBT chimathandizira ma wavelength atatu okha: 850nm, 1310nm, ndi 1550nm, zomwe zimapangitsa kuti chisagwire ntchito pa ma wavelength ena. Chigawo cha PLC chimatha kuthandizira ma wavelength kuyambira 1260 mpaka 1650nm. Kuchuluka kwa ma wavelength komwe kumasinthika kumapangitsa kuti chigawo cha PLC chikhale choyenera kugwiritsidwa ntchito kwambiri.
2. Chiŵerengero Chogawanika
Chiŵerengero cha kugawanika chimasankhidwa ndi zolowetsa ndi zotuluka za chogawaniza chingwe cha optical. Chiŵerengero chachikulu cha kugawanika kwa FBT splitter ndi 1:32, zomwe zikutanthauza kuti zolowetsa chimodzi kapena ziwiri zitha kugawidwa m'magulu otulutsa ma ulusi 32 nthawi imodzi. Komabe, chiŵerengero cha kugawanika kwa chogawaniza cha PLC ndi 1:64 - zolowetsa chimodzi kapena ziwiri zokhala ndi ma ulusi 64. Kupatula apo, chogawaniza cha FBT chimasinthidwa, ndipo mitundu yapadera ndi 1:3, 1:7, 1:11, ndi zina zotero. Koma chogawaniza cha PLC sichingasinthidwe, ndipo chili ndi mitundu yokhazikika monga 1:2, 1:4, 1:8, 1:16, 1:32, ndi zina zotero.
3. Kugawanitsa Kufanana
Chizindikiro chomwe chimakonzedwa ndi ma splitter a FBT sichingagawanidwe mofanana chifukwa cha kusowa kwa kayendetsedwe ka ma signali, kotero mtunda wake wotumizira ukhoza kukhudzidwa. Komabe, splitter ya PLC imatha kuthandizira ma splitter ofanana pa nthambi zonse, zomwe zingatsimikizire kuti ma transmission optical ndi okhazikika.
4. Chiwongola dzanja cholephera
FBT splitter nthawi zambiri imagwiritsidwa ntchito pa ma network omwe amafuna kuti splitter ikhazikitsidwe osakwana ma split anayi. Kugawanika kwakukulu, kulephera kumakhala kwakukulu. Pamene chiŵerengero chake chogawanika chili chachikulu kuposa 1:8, zolakwika zambiri zimachitika ndipo zimayambitsa kulephera kwakukulu. Chifukwa chake, FBT splitter imakhala yochepa kwambiri pa chiwerengero cha ma split mu coupling imodzi. Koma kulephera kwa PLC splitter kumakhala kochepa kwambiri.
5. Kutaya Kodalira Kutentha
M'madera ena, kutentha kungakhale chinthu chofunikira kwambiri chomwe chimakhudza kutayika kwa zinthu zowunikira. FBT splitter imatha kugwira ntchito bwino kutentha kwa -5 mpaka 75℃. PLC splitter imatha kugwira ntchito kutentha kwapakati pa -40 mpaka 85 ℃, zomwe zimapangitsa kuti zinthu zizigwira bwino ntchito m'madera omwe nyengo imakhala yovuta kwambiri.
6. Mtengo
Chifukwa cha ukadaulo wovuta wopanga wa PLC splitter, mtengo wake nthawi zambiri umakhala wokwera kuposa FBT splitter. Ngati ntchito yanu ndi yosavuta komanso yopanda ndalama, FBT splitter ingapereke yankho lotsika mtengo. Komabe, kusiyana kwa mitengo pakati pa mitundu iwiri ya splitter kukuchepa pamene kufunikira kwa PLC splitter kukupitirira kukwera.
7. Kukula
Ma splitter a FBT nthawi zambiri amakhala ndi kapangidwe kokulirapo komanso kokulirapo poyerekeza ndi ma splitter a PLC. Amafuna malo ambiri ndipo ndi oyenera kugwiritsa ntchito pomwe kukula sikolepheretsa. Ma splitter a PLC ali ndi mawonekedwe ocheperako, zomwe zimapangitsa kuti aziphatikizika mosavuta m'maphukusi ang'onoang'ono. Amapambana kwambiri pamapulogalamu okhala ndi malo ochepa, kuphatikiza mkati mwa ma patch panels kapena ma optical network terminals.
