Kodi Fiber Optic Splitter Ndi Chiyani?

Masiku ano optical networkmitundu, kubwera kwafiber optic splitterzimathandizira kuthandizira ogwiritsa ntchito kukulitsa magwiridwe antchito a ma optical network circuits.Fiber optic splitter, yomwe imatchedwanso optical splitter, kapena beam splitter, ndi chophatikizikachiwongolero cha mafundechipangizo chogawa magetsi chomwe chitha kugawa kuwala kochitika kukhala nthiti ziwiri kapena kupitilira apo, mosemphanitsa, chokhala ndi zolowetsa zingapo ndi zotuluka.Optical splitter yakhala ndi gawo lofunikira pamanetiweki owoneka bwino (monga EPON, GPON, BPON, FTTX, FTTH, etc.) polola mawonekedwe amodzi a PON kugawidwa pakati pa olembetsa ambiri.

Kodi Fiber Optic Splitter Imagwira Ntchito Motani?

Nthawi zambiri, chizindikiro cha kuwala chikalowa mumtundu umodzi wa fiber, mphamvu yowunikirayo siingathe kukhazikika pakatikati pa fiber.Mphamvu yaing'ono idzafalikira kupyolera mu kuphimba kwa ulusi.Ndiko kunena kuti, ngati ulusi uŵiri uli pafupi kokwanirana wina ndi mzake, kuunika kopatsirana mu ulusi wa kuwala kungaloŵe mu ulusi wina wa kuwala.Chifukwa chake, njira yosinthiranso siginecha ya kuwala imatha kupezeka mumitundu ingapo, momwemonso fiber optic splitter imayambira.

Mwachindunji, passive optical splitter imatha kugawa, kapena kulekanitsa, kuwala kwa chochitika kukhala nthiti zingapo zowunikira pamlingo wina.Kapangidwe kagawo ka 1 × 4 kamene kali m'munsimu ndi kamangidwe kake: kulekanitsa mtengo wowala wa zochitika kuchokera ku chingwe chimodzi cholowetsa CHIKWANGWANI kukhala zitsulo zinayi zowala ndikuzitumiza kudzera mu zingwe zinayi zotulutsa.Mwachitsanzo, ngati chingwe cholowetsa CHIKWANGWANI chamawonedwe chimanyamula 1000 Mbps bandwidth, wogwiritsa aliyense kumapeto kwa zingwe zotulutsa fiber amatha kugwiritsa ntchito netiweki ndi 250 Mbps bandwidth.

Chogawanitsa chamagetsi chokhala ndi 2 × 64 masinthidwe ogawanika ndi ovuta pang'ono kusiyana ndi 1 × 4 kugawanika kosinthika.Pali ma terminals awiri olowera ndi makumi asanu ndi limodzi mphambu anayi otulutsa mu chogawa cha Optical mu 2 × 64 magawo ogawanika.Ntchito yake ndikugawa mizati iwiri yowunikira kuchokera ku zingwe ziwiri zolowera m'miyendo yowunikira makumi asanu ndi limodzi mphambu zinayi ndikuwatumiza kudzera pazingwe makumi asanu ndi limodzi mphambu zinayi.Ndi kukula kofulumira kwa FTTx padziko lonse lapansi, kufunikira kwa masinthidwe okulirapo pamanetiweki kwawonjezeka kuti atumikire ambiri olembetsa.

Mitundu ya Fiber Optic Splitter

Zosankhidwa ndi Package Style

The kuwalazogawaitha kuthetsedwa ndi mitundu yosiyanasiyana yolumikizira, ndipo phukusi loyambirira litha kukhala mtundu wa bokosi kapena mtundu wa chubu chosapanga dzimbiri.Fiber optic splitter box nthawi zambiri imagwiritsidwa ntchito ndi chingwe cha 2mm kapena 3mm chakunja, pomwe chinacho chimagwiritsidwa ntchito limodzi ndi zingwe zakunja za 0.9mm.Kupatula apo, ili ndi masinthidwe osiyanasiyana ogawanika, monga 1×2, 1×8, 2×32, 2×64, etc.

Amasankhidwa ndi Transmission Medium

Malinga ndi ma mediums osiyanasiyana opatsirana, pali single mode Optical splitter ndi multimode Optical splitter.Multimode Optical splitter imatanthauza kuti CHIKWANGWANI chimakongoletsedwa ndi 850nm ndi 1310nm, pomwe mawonekedwe amodzi amatanthauza kuti CHIKWANGWANI chimakongoletsedwa ndi 1310nm ndi 1550nm.Kupatula apo, kutengera kusiyana kwa kutalika kwa mawonekedwe, pali zenera limodzi ndi mazenera apawiri opangira mazenera-oyamba ndi kugwiritsa ntchito mawonekedwe amodzi ogwirira ntchito, pomwe chogawa cha fiber optic chomaliza chimakhala ndi mafunde awiri ogwirira ntchito.

Zosankhidwa ndi Manufacturing Technique

FBT splitter imachokera paukadaulo wakale wowotcherera ulusi zingapo pamodzi kuchokera kumbali ya ulusi, zokhala ndi zotsika mtengo.Zithunzi za PLCzimachokera ku planar lightwave circuit technology, yomwe imapezeka mumitundu yosiyanasiyana, kuphatikizapo 1:4, 1:8, 1:16, 1:32, 1:64, etc, ndipo ikhoza kugawidwa m'magulu angapo monga opandaPulogalamu ya PLC, blockless PLC ziboda, ABS ziboda, LGX bokosi ziboda, fanout PLC ziboda, mini pulagi-mu mtundu PLC ziboda, etc.

Onani tchati chofananira cha PLC Splitter vs FBT Splitter:

Ntchito ya Fiber Optic Splitter mu PON Networks

Optical splitters, zomwe zimathandiza kuti chizindikiro pazitsulo za kuwala zigawidwe pakati pa zingwe ziwiri kapena zingapo zokhala ndi zosiyana zosiyana (1 × N kapena M × N), zakhala zikugwiritsidwa ntchito kwambiri pamagulu a PON.FTTH ndi imodzi mwazambiri zomwe zimagwiritsidwa ntchito.Zomangamanga za FTTH ndi: Optical Line Terminal (OLT) yomwe ili muofesi yapakati;Optical Network Unit (ONU) yomwe ili kumapeto kwa ogwiritsa ntchito;Optical Distribution Network (ODN) idakhazikika pakati pa ziwiri zam'mbuyomu.Chogawanitsa chowunikira chimagwiritsidwa ntchito nthawi zambiri mu ODN kuthandiza ogwiritsa ntchito angapo kugawana mawonekedwe a PON.

Mfundo-ndi-multipoint FTTH maukonde kutumizidwa akhoza zina kugawidwa pakati (imodzi-siteji) kapena cascaded (Mipikisano siteji) ziboda kasinthidwe mu gawo kugawa maukonde FTTH.Kusintha kwapakati pazigawo nthawi zambiri kumagwiritsa ntchito chiŵerengero chogawanika cha 1:64, ndi chogawanitsa cha 1:2 mu ofesi yapakati, ndi 1:32 m'chipinda chakunja (OSP) monga nduna.Kapangidwe kagawo kakang'ono kapena kagawidwe kagawo kamakhala kopanda zogawa muofesi yapakati.Doko la OLT limalumikizidwa / kulumikizidwa molunjika ku ulusi wazomera wakunja.Gawo loyamba la kugawanika (1: 4 kapena 1: 8) limayikidwa potseka, osati kutali ndi ofesi yapakati;gawo lachiwiri la zogawanitsa (1:8 kapena 1:16) lili m'mabokosi otsekera, pafupi ndi malo a kasitomala.Centralized Splitting vs Distributed Splitting mu PON Based FTTH Networks iwonetsanso njira ziwiri zogawanika zomwe zimagwiritsa ntchito ma fiber optic splitters.

Kodi Mungasankhire Bwanji Fiber Optic Splitter Yoyenera?

Nthawi zambiri, chogawa chapamwamba cha fiber optic chimafunikira kuyesa mayeso angapo.Zizindikiro zomwe zingakhudze fiber optic splitter ndi izi:

Kutayika kwa kuyika: Kumatanthauza dB ya zotulutsa zilizonse zokhudzana ndi kutayika kwa kuwala.Kawirikawiri, kuchepa kwa mtengo woyikapo kutayika, kumapangitsanso bwino ntchito ya splitter.

Kubwereranso kutayika: Kumatchedwanso kuti reflection loss, kumatanthauza kutaya mphamvu kwa siginecha ya kuwala yomwe imabwezedwa kapena kuwonetseredwa chifukwa cha kutha kwa fiber kapena chingwe chotumizira.Kawirikawiri, kutayika kwakukulu kobwerera, kumakhala bwino.

Kugawanika chiŵerengero: Kutanthauzidwa ngati mphamvu linanena bungwe la ziboda linanena bungwe doko mu dongosolo ntchito, amene amagwirizana ndi wavelength wa kuwala opatsirana.

Kudzipatula: Imawonetsa njira yopepuka yopatsira optical kunjira zina zodzipatula za optical signal.

Kupatula apo, kufanana, kuwongolera, ndi kutayika kwa PDL polarization ndizofunikanso zomwe zimakhudza magwiridwe antchito a mtengo wogawa.

Pazosankha zenizeni, FBT ndi PLC ndi zosankha ziwiri zazikulu za ogwiritsa ntchito ambiri.Kusiyana pakati pa FBT splitter vs PLC splitter nthawi zambiri kumakhala kutalika kwa kutalika kwa ntchito, kugawanika kwa chiŵerengero, kuchepa kwa asymmetric pa nthambi iliyonse, kulephera kulephera, ndi zina zotero.PLC ziboda zokhala ndi kusinthasintha kwabwino, kukhazikika kwakukulu, kulephera kutsika, komanso kusiyanasiyana kwa kutentha kumatha kugwiritsidwa ntchito pamakachulukidwe apamwamba.

Pazowonongera, mitengo ya ma splitter a PLC nthawi zambiri imakhala yokwera kuposa ya FBT yogawa chifukwa chaukadaulo wazopanga.M'makonzedwe apadera, masinthidwe ogawanika pansi pa 1 × 4 akulangizidwa kuti agwiritse ntchito FBT splitter, pamene makonzedwe ogawanika pamwamba pa 1 × 8 akulimbikitsidwa kwa PLC splitters.Pakutumiza kwa mafunde amodzi kapena awiri, zogawa za FBT zitha kupulumutsa ndalama.Pakutumiza kwa Broadband PON, PLC splitter ndi chisankho chabwinoko poganizira kukulitsa ndi kuwunika kwamtsogolo.

Mawu Omaliza

Zigawo za fiber optic zimathandizira kuti chizindikiro pa chingwe cha kuwala chigawidwe pakati pa ulusi uwiri kapena kuposerapo.Popeza ma splitter alibe magetsi kapena amafuna mphamvu, ndi gawo lofunikira kwambiri ndipo amagwiritsidwa ntchito kwambiri pama network ambiri a fiber-optic.Chifukwa chake, kusankha ma fiber optic splitters kuti athandizire kukulitsa kugwiritsa ntchito bwino kwa mawonekedwe owoneka bwino ndikofunikira pakukulitsa kamangidwe kamaneti komwe kadzakhala mtsogolo.
