Ku-FTTx kanye ne-PON architectures, i-optical spliter idlala indima ebaluleke kakhulu ekudaleni izinhlobo ezahlukene zamanethiwekhi e-fiber optic avela kumaphuzu amaningi. Kodwa uyazi ukuthi iyini i-fiber optic splitter? empeleni, i-fiber opticspliter iyidivayisi ye-optical engahlukanisa noma ihlukanise ukukhanya kwesigameko ibe yizibani ezimbili noma ngaphezulu. Ngokuyisisekelo, kunezinhlobo ezimbili ze-fiber splitter ezihlukaniswe ngesimiso sazo sokusebenza: i-fused biconicaltaper splitter (i-FBT splitter) kanye ne-planar lightwave circuit splitter (i-PLC splitter). Ungase ube nombuzo owodwa: yini umehluko phakathi kwazo futhi kufanele sisebenzise i-FBT noma i-PLC splitter?
KuyiniI-FBT Splitter?
I-splitter ye-FBT isekelwe kubuchwepheshe bendabuko, okuwuhlobo lwe-Ukungenzi luthoUkuthepha Kwenethiwekhi, okubandakanya ukuhlanganiswa kwemicu eminingana ohlangothini lwemicu ngayinye. Imicu iqondiswa ngokuyifudumeza endaweni ethile nobude obuthile. Ngenxa yobuthakathaka bemicu ehlanganisiwe, ivikelwe yishubhu yengilazi eyenziwe nge-epoxy ne-silica powder. Ngemva kwalokho, ishubhu yensimbi engagqwali imboza ishubhu yengilazi yangaphakathi futhi ivalwe nge-silicon. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ikhwalithi yama-splitter e-FBT ithuthuke kakhulu, okwenza abe yisisombululo esingabizi kakhulu. Ithebula elilandelayo lichaza izinzuzo kanye nokungalungi kwama-splitter e-FBT.

KuyiniI-PLC Splitter?
I-PLC splitter isekelwe kubuchwepheshe besekethe ye-planar lightwave, okuwuhlobo lweUkungenzi luthoUkuthepha Kwenethiwekhi. Yakhiwe izendlalelo ezintathu: i-substrate, i-waveguide, kanye nesembozo. I-waveguide idlala indima ebalulekile enqubweni yokuhlukanisa evumela ukudlula amaphesenti athile okukhanya. Ngakho-ke isignali ingahlukaniswa ngokulinganayo. Ngaphezu kwalokho, ama-PLC splitter atholakala ngezilinganiso ezahlukahlukene zokuhlukanisa, kufaka phakathi i-1:4, 1:8, 1:16, 1:32, 1:64, njll. Futhi anezinhlobo eziningana, njenge-bare PLC splitter, i-blockless PLC splitter, i-fananout PLC splitter, i-mini plug-in type PLC splitter, njll. Ungahlola futhi isihloko esithi Ungakanani Owaziyo Nge-PLC Splitter? ukuthola ulwazi olwengeziwe mayelana ne-PLC splitter. Ithebula elilandelayo libonisa izinzuzo kanye nokungalungi kwe-PLC splitter.

I-FBT Splitter vs PLC Splitter: Uyini Umehluko?(Ukuze wazi kabanzi mayelanaUyini umehluko phakathi kwe-Passive Network Tap kanye ne-Active Network Tap?)
1. Ubude beWave yokusebenza
I-splitter ye-FBT isekela ama-wavelength amathathu kuphela: i-850nm, i-1310nm, kanye ne-1550nm, okwenza ingakwazi ukusebenza kwamanye ama-wavelength. I-splitter ye-PLC ingasekela ama-wavelengths kusukela ku-1260 kuya ku-1650nm. Ububanzi obulungisekayo be-wavelength benza i-PLC splitter ifanelekele ukusetshenziswa okwengeziwe.
2. Isilinganiso Sokuhlukanisa
Isilinganiso sokuqhekeka sinqunywa ngokufaka kanye nokuphuma kwe-optical cable splitter. Isilinganiso sokuqhekeka esiphezulu se-FBT splitter sifinyelela ku-1:32, okusho ukuthi okufakiwe okukodwa noma okubili kungahlukaniswa kube yi-output maximum yezintambo ezingu-32 ngesikhathi esisodwa. Kodwa-ke, isilinganiso sokuqhekeka se-PLC splitter sifinyelela ku-1:64 - okufakiwe okukodwa noma okubili okunomkhawulo wokuphuma wezintambo ezingu-64. Ngaphandle kwalokho, i-FBT splitter ingenziwa ngokwezifiso, futhi izinhlobo ezikhethekile ziyi-1:3, 1:7, 1:11, njll. Kodwa i-PLC splitter ayinakwenziwa ngokwezifiso, futhi inezinguqulo ezijwayelekile kuphela ezifana ne-1:2, 1:4, 1:8, 1:16, 1:32, njalo njalo.
3. Ukuhlukanisa Ukufana
Isignali ecutshungulwa yi-FBT splitters ayikwazi ukuhlukaniswa ngokulinganayo ngenxa yokuntuleka kokuphathwa kwesignali, ngakho-ke ibanga layo lokudlulisela lingathinteka. Kodwa-ke, i-PLC splitter ingasekela izilinganiso ezilinganayo ze-splitter kuwo wonke amagatsha, okungaqinisekisa ukudluliswa okuzinzile kwe-optical.
4. Izinga Lokwehluleka
I-splitter ye-FBT ivame ukusetshenziselwa amanethiwekhi adinga ukucushwa kwe-splitter okungaphansi kwama-split angu-4. Uma i-splitter inkulu, izinga lokuhluleka liba likhulu. Uma isilinganiso sayo sokuqhekeka sikhulu kuno-1:8, kuzovela amaphutha amaningi futhi kubangele izinga lokuhluleka eliphezulu. Ngakho-ke, i-splitter ye-FBT inqunyelwe kakhulu enanini lama-split ku-coupling eyodwa. Kodwa izinga lokuhluleka le-PLC splitter lincane kakhulu.
5. Ukulahlekelwa Okuxhomeke Ekushiseni
Ezindaweni ezithile, izinga lokushisa lingaba yinto ebalulekile ethinta ukulahlekelwa kokufakwa kwezingxenye ze-optical. I-FBT splitter ingasebenza kahle ngaphansi kwezinga lokushisa elingu--5 kuya ku-75℃. I-PLC splitter ingasebenza ebangeni lokushisa elibanzi elingu--40 kuya ku-85 ℃, okuhlinzeka ngokusebenza okuhle ezindaweni ezinesimo sezulu esibi kakhulu.
6. Intengo
Ngenxa yobuchwepheshe bokukhiqiza obuyinkimbinkimbi be-PLC splitter, izindleko zayo ngokuvamile ziphakeme kune-FBT splitter. Uma isicelo sakho silula futhi singenayo imali, i-FBT splitter ingakunikeza ikhambi elingabizi kakhulu. Noma kunjalo, igebe lentengo phakathi kwezinhlobo ezimbili ze-splitter liyancipha njengoba isidingo se-PLC splitter siqhubeka nokukhula.
7. Usayizi
Ama-splitter e-FBT ngokuvamile anomklamo omkhulu nomkhulu uma kuqhathaniswa nama-splitter e-PLC. Adinga isikhala esiningi futhi afaneleka kangcono izinhlelo zokusebenza lapho usayizi ungeyona into evimbelayo. Ama-splitter e-PLC anesimo esiqinile, okwenza ahlanganiswe kalula emaphaketheni amancane. Ahamba phambili ezinhlelweni zokusebenza ezinesikhala esilinganiselwe, kufaka phakathi amaphaneli angaphakathi noma ama-terminal enethiwekhi ye-optical.
