Ezakhiweni ze-FTTx ne-PON, isihlukanisi esibonakalayo sidlala indima ebalulekile ekhulayo ukudala amanethiwekhi ahlukahlukene we-point-to-multipoint fiber optic. Kodwa ingabe uyazi ukuthi yini i-fiber optic splitter? empeleni, i-fiber opticspliter iyisisetshenziswa sokubona esingahle sihlukanise noma sihlukanise i-beam yokukhanya yesigameko ibe ama-lightbeam amabili noma ngaphezulu. Ngokuyisisekelo, kunezinhlobo ezimbili ze-fiber splitter ezihlukaniswa ngesimiso sazo sokusebenza: isihlukanisi se-biconicaltaper esihlanganisiwe (isihlukanisi se-FBT) kanye nesihlukanisi sesifunda se-lightwave esiplana (i-PLC splitter). Ungase ube nombuzo owodwa :uyini umehluko phakathi kwazo futhi sizosebenzisa isihlukanisi se-FBT noma se-PLC?
YiniI-FBT Splitter?
Isihlukanisi se-FBT sisekelwe kubuchwepheshe bendabuko, obubandakanya ukuhlangana kwemicu eminingana ukusuka ohlangothini lwefayibha ngayinye. Imicu iqondaniswe ngokuyishisisa endaweni ethile nobude. Ngenxa yobuthakathaka bemicu ehlanganisiwe, ivikelwe ishubhu lengilazi elenziwe nge-epoxy ne-silica powder. Kamuva, ishubhu lensimbi engagqwali limboza ithubhu lengilazi elingaphakathi futhi livalwe nge-silicon. Njengoba ubuchwepheshe buqhubeka buthuthuka, ikhwalithi yezihlukanisi ze-FBT iye yathuthuka kakhulu, okubenza babe yisixazululo esingabizi kakhulu. Ithebula elilandelayo libonisa izinzuzo kanye nokubi kwezihlukanisi ze-FBT.

YiniI-PLC Splitter?
Isihlukanisi se-PLC sisekelwe kubuchwepheshe besifunda se-lightwave. Inezigaba ezintathu: i-substrate, i-waveguide, nesivalo. I-waveguide idlala indima ebalulekile enqubweni yokuhlukanisa evumela ukudlula amaphesenti athile okukhanya. Ngakho isignali ingahlukaniswa ngokulinganayo. Ngaphezu kwalokho, izihlukanisi ze-PLC zitholakala ngezilinganiso ezihlukahlukene zokuhlukaniswa, okuhlanganisa u-1:4, 1:8, 1:16, 1:32, 1:64, njll. Futhi zinezinhlobo ezimbalwa, njengesihlukanisi esingenalutho se-PLC, esingavimbeli. Isihlukanisi se-PLC, isihlukanisi se-fanout PLC, isihlukanisi se-plug-in esincane se-PLC, njll. Ungahlola futhi isihloko esithi Kungakanani Okwaziyo Nge-PLC Splitter? ukuze uthole ulwazi olwengeziwe mayelana ne-PLC splitter. Ithebula elilandelayo libonisa izinzuzo kanye nokubi kwe-PLC splitter.

I-FBT Splitter vs PLC Splitter: Uyini Umehluko?
1. I-Wavelength esebenzayo
Isihlukanisi se-FBT sisekela kuphela amaza amaza amathathu: 850nm, 1310nm, kanye no-1550nm, okwenza ingakwazi ukusebenza kwamanye amaza. Isihlukanisi se-PLC singasekela amaza amaza ukusuka ku-1260 kuya ku-1650nm. Ibanga elingalungiseka le-wavelength lenza isihlukanisi se-PLC silungele izinhlelo zokusebenza eziningi.
2. Ukuhlukanisa Isilinganiso
Isilinganiso sokuhlukanisa sinqunywa okokufaka kanye nokuphumayo kwe-optical cable splitter. Isilinganiso esiphezulu sokuhlukanisa se-FBT sihlukanisiwe sifika ku-1:32, okusho ukuthi okokufaka okukodwa noma okubili kungahlukaniswa kube umkhawulo ophumayo wamafiber angu-32 ngesikhathi. Kodwa-ke, isilinganiso sokuhlukaniswa kwe-PLC sihlukanisile sifinyelela ku-1:64 - okokufaka okukodwa noma okubili okunomkhawulo ophumayo wamafayibha angama-64. Ngaphandle kwalokho, isihlukanisi se-FBT singenziwa ngendlela oyifisayo, futhi izinhlobo ezikhethekile ngu-1:3, 1:7, 1:11, njll. Kodwa isihlukanisi se-PLC akwenzeki ngokwezifiso, futhi sinezinguqulo ezijwayelekile kuphela ezifana no-1:2, 1:4, 1 :8, 1:16, 1:32, njalo njalo.
3. Ukuhlukanisa Ukufana
Isignali ecutshungulwe ngabahlukanisi be-FBT ayikwazi ukuhlukaniswa ngokulinganayo ngenxa yokuntuleka kokuphatha amasignali, ngakho ibanga layo lokudlulisela lingathinteka. Kodwa-ke, i-PLC splitter ingasekela izilinganiso ezilinganayo ze-splitter kuwo wonke amagatsha, angaqinisekisa ukudluliswa kokubona okuzinzile.
4. Izinga Lokwehluleka
Isihlukanisi se-FBT sivamise ukusetshenziselwa amanethiwekhi adinga ukumiswa kwesihlukanisi esingaphansi kokuhlukaniswa okungu-4. Uma ukuhlukana kukhudlwana, izinga lokuhluleka likhulu. Uma isilinganiso sayo sokuhlukaniswa sikhulu kuno-1:8, amaphutha amaningi azokwenzeka futhi abangele izinga eliphezulu lokuhluleka. Ngakho-ke, isihlukanisi se-FBT sikhawulelwe kakhulu enanini lokuhlukaniswa kokuhlanganisa okukodwa. Kodwa izinga lokuhluleka kwe-PLC splitter lincane kakhulu.
5. Ukulahlekelwa Okuncike Kwezinga lokushisa
Ezindaweni ezithile, izinga lokushisa lingaba yisici esibalulekile esithinta ukulahlekelwa kokufakwa kwezingxenye ze-optical. Isihlukanisi se-FBT singasebenza sizinzile ngaphansi kwezinga lokushisa elingu -5 ukuya ku-75℃. I-PLC splitter ingasebenza ebangeni lokushisa elibanzi elingu -40 kuya ku-85 ℃, inikeze ukusebenza okuhle uma kuqhathaniswa ezindaweni ezinesimo sezulu esibi kakhulu.
6. Inani
Ngenxa yobuchwepheshe bokukhiqiza obuyinkimbinkimbi be-PLC splitter, izindleko zayo ngokuvamile ziphezulu kunesihlukanisi se-FBT. Uma isicelo sakho silula futhi sishoda ngemali, isihlukanisi se-FBT singakunikeza isisombululo esingabizi kakhulu. Noma kunjalo, igebe lentengo phakathi kwezinhlobo ezimbili zokuhlukanisa liyancipha njengoba isidingo sabahlukanisi be-PLC siqhubeka nokukhuphuka.
7. Usayizi
Izihlukanisi ze-FBT zivame ukuba nomklamo omkhulu futhi omkhulu uma kuqhathaniswa nezihlukanisi ze-PLC. Zifuna indawo ethe xaxa futhi zifaneleka kangcono izinhlelo zokusebenza lapho usayizi ungeyona into ekhawulelayo. Izihlukanisi ze-PLC ziziqhayisa nge-compact form factor, ezenza zihlanganiswe kalula kumaphakheji amancane. Zihamba phambili ezinhlelweni zokusebenza ezinesikhala esilinganiselwe, okuhlanganisa amaphaneli angaphakathi noma amatheminali enethiwekhi yokubona.
