Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Kuyini i-PLC Splitter?
I-PLC splitter ichazwa njengedivayisi ye-optical engasebenzi esebenzisa ubuchwepheshe be-Planar Lightwave Circuit. Isakhiwo sayo siqukethe izendlalelo ezintathu eziyinhloko: i-substrate, i-waveguide, kanye nesembozo esivikelayo. I-waveguide ehlanganisiwe ibalulekile emsebenzini wokuhlukanisa, okwenza ikwazi ukulawula nokusabalalisa ukukhanya ngokunembile. Lobu buchwepheshe buqinisekisa ukuthi amasignali ahlukaniswe ngokufana okuphezulu. Ngaphezu kwalokho, ama-PLC splitter asekela ububanzi bezilinganiso zokuhlukanisa ezijwayelekile, njenge-1:4, 1:8, kuze kufike ku-1:64, futhi iza ngezindlela ezahlukahlukene kufaka phakathi i-fiber engenalutho, i-blockless, i-fanaout, kanye nezinhlobo ze-plug-in ezincane.
Kuyini i-FBT Splitter?
I-splitter ye-FBT (Fused Biconical Taper) isebenzisa indlela yokukhiqiza yakudala lapho imicu ye-optical ihlanganiswa khona futhi ihlanganiswe ndawonye. Inqubo iqala ngokuvumelanisa nokushisa imicu eminingi endaweni eqondile ukuze kudalwe indawo ehlanganisiwe. Njengoba inikezwe ubumnandi obungokwemvelo bale ndawo ehlanganisiwe, iqala ihlanganiswe ngaphakathi kwepayipi elivikelayo, elivame ukwakhiwa nge-epoxy ne-silica. Lokhu kuhlanganiswa kube sekufakwa epayipini lensimbi engagqwali eliqinile bese livalwa nge-silicone ukuze lihlale isikhathi eside. Njengobuchwepheshe obuvuthiwe, ama-splitter e-FBT abone ukuthuthuka okuqhubekayo, enikeza isisombululo se-optical esithembekile kakhulu nesingabizi kakhulu.
I-FBT Splitter vs PLC Splitter: Uyini Umehluko?
1. Inqubo Yokukhiqiza
I-PLC splitter ikhiqizwa kusetshenziswa amasu okuhlanganisa ama-semiconductor. Yakhiwe phezu kwe-quartz substrate, lapho amasekethe e-precision optical waveguide enziwa khona nge-photolithography, etching, kanye nezinqubo zokuthuthukisa. Ngemva kwalokho, iziphetho zokufaka nezokukhipha zihlanganiswa nama-fiber arrays amaningi futhi zipakishwe. Inqubo yayo yonke yokukhiqiza ilandela eduze indlela yokukhiqiza amasekethe ahlanganisiwe.
Ekwenzeni i-FBT coupler, imicu emibili noma ngaphezulu ye-optical ehlutshiwe iyasontwa ndawonye bese ifakwa elangeni lokushisa eliphezulu. Iyahlanganiswa futhi inciphe ngokunwetshwa ngendlela ebheke eceleni ngenkathi isilinganiso sokuqhekeka siqashwa ngesikhathi sangempela. Ukunwebeka kuyama uma isilinganiso esiqondiwe sesifinyelelwe, futhi i-fiber eningi isusiwe, kusale kuphela ama-port okufaka nokukhipha. Indawo enciphile ibe isiboshwa kwi-quartz substrate bese ifakwa ngaphakathi kwepayipi lensimbi engagqwali. Le ndlela incike kakhulu ekhonweni lomqhubi kanye nokunemba kwemishini.
2. Isimiso Sokuhlukanisa Ukukhanya
Isebenzisa i-array ye-optical waveguide ehlanganisiwe ku-chip yayo, i-PLC splitter ifinyelela ukusatshalaliswa kwamandla okufanayo kokukhanya kokufaka ngobunjiniyela obunembile bephrofayili yenkomba yokubuyisa kuyo yonke isekethe. Lokhu kusabalala okulawulwayo kuqondisa isignali echwebeni ngalinye lokukhipha ngokuhambisana okuphezulu.
I-splitter ye-FBT isebenza ngokusekelwe kumphumela wokuxhumanisa insimu ye-evanescent phakathi kwemicu ye-optical. Lapho ama-core amabili emicu ye-optical elethwa eduze, ahlanganiswe, futhi anciphe, amasimu awo emodi ye-optical ayahlangana futhi asebenzisane. Ngokulawula ngokunembile ubude bokwelula kanye ne-angle yokujika ngesikhathi senqubo yokunciphisa, izinga lokuxhuma liyalungiswa, ngaleyo ndlela kufezwe ukusatshalaliswa okufiselekayo kwamandla e-optical.
3. Ukwehlukanisa Amandla
Ubuchwepheshe be-PLC buhamba phambili ezinhlelweni zokusebenza ezidinga i-fan-out ephezulu, busekela ukuhlukaniswa okufika ku-1×64 nangaphezulu kumojuli eyodwa ehlanganisiwe. Lokhu kukhula kuhumusha isakhiwo sezindleko esikhangayo: uma isilinganiso sokuhlukaniswa siphezulu, kulapho inzuzo yezindleko ikhula khona ngesiteshi ngasinye. Bunikeza ukucushwa kwe-port okuguquguqukayo ekuqhubekeni kwejometri okujwayelekile (isb., 1×2, 1×4, 1×8, 1×16, 1×64; 2×4, 2×8, 2×16, 2×32, 2×64).
Ngokungafani nobuchwepheshe be-PLC, indlela yokukhiqiza ye-FBT evamile inqunyelwe kakhulu ekuphumeni kwesiteshi esiphansi (ngokuyinhloko i-1×2 kanye ne-1×4) ngesigaba ngasinye esihlanganisiwe. Ukwakha idivayisi efana ne-1×8 splitter kudinga ukuxhumanisa amamojula amaningana ayisisekelo e-1×2 ngaphakathi kwephakheji evamile, okuholela enkambisweni yokuhlanganisa eyinkimbinkimbi kakhulu. Inzuzo ephawulekayo ye-FBT ukuguquguquka kwayo ekukhiqizeni ububanzi obukhulu bezilinganiso zokwahlukana ezingalingani (isb., 1×N, 2×N).
4. Isilinganiso sokuhlukanisa
Ama-splitter e-PLC aklanyelwe kakhulu ukuhlukaniswa kwamandla alinganayo. Isibonelo, i-splitter ye-1×2 PLC ingafinyelela kuphela isilinganiso sokuhlukaniswa esingu-50:50
Ama-splitter e-FBT asekela ukusatshalaliswa kwamandla okuguquguqukayo, anezilinganiso ezingenziwa ngokwezifiso ezifana no-1:99, 2:98, 20:80, kanye no-30:70, ezingalungiswa ngokwezimo ezithile zohlelo lokusebenza.
5. Ububanzi Bokumbozwa Kobude Bamagagasi
I-PLC splitter ibonisa ifasitela elibanzi lokusebenza kusukela ku-1260 nm kuya ku-1650 nm. Le spectrum ihlanganisa ngokuphelele wonke ama-telecommunication band amakhulu: i-O-band (1260-1360nm), i-E-band (1360-1460nm), i-S-band (1460-1530nm), i-C-band (1530-1565nm), kanye ne-L-band (1565-1625nm). Ukusebenza okunjalo kwe-wideband kwenza kube lula ukuhambisana nezinhlelo zokudlulisa ze-multi-wavelength kanye ne-coarse/fine wavelength division multiplexing (CWDM/DWDM).
I-splitter ye-FBT yenzelwe ukusebenza ngama-wavelength amathathu ahlukene: 850nm, 1310nm, kanye no-1550nm. Lokhu kuhambisana nama-wavelength ajwayelekile okudlulisa ama-multimode afushane, amanethiwekhi okufinyelela emodi eyodwa, kanye namanethiwekhi omgogodla we-long-haul, ngokulandelana. Lokhu kusekelwa kwama-wavelength okulinganiselwe kuyivimbela ukuthi imboze ububanzi obudingekayo ezinhlelweni zokusebenza ze-full-band.
6. Izimo Zokusebenza
Ama-splitter e-PLC afaneleka kakhulu kumanethiwekhi amakhulu asebenza kahle kakhulu. Izinhlelo zokusebenza ezibalulekile zifaka phakathi i-Fiber-to-the-Home (FTTH) kanye ne-Passive Optical Networks (PON) njenge-GPON/EPON, i-5G fronthaul ku-CRAN architectures, i-data center leaf-spine interconnections, kanye nezinhlelo zokuzwa i-fiber ezizwela i-polarization—konke okudinga ukuzinza okuphezulu, ukuhlukana okufanayo, kanye nokusebenza kwe-broadband.
I-splitter ye-FBT isetshenziswa kakhulu ezinhlelweni zokusebenza ezincane, ezingabizi kakhulu lapho ukuhlukaniswa okuguquguqukayo, okungenaziteshi eziphansi kwanele. Amacala ajwayelekile okusetshenziswa afaka ama-LAN e-fiber optic emabhizinisini amancane, ukuhlanganiswa kwesignali ekuqapheni noma amanethiwekhi e-CATV, kanye nokusethwa kwesikhashana kokuhlola noma ukuthunyelwa kwenethiwekhi yomphetho, ikakhulukazi lapho ukubalwa kokuhlukaniswa kuphansi (isb., 1×2, 1×3, 1×4).
7. Izinga Lokushisa Lokusebenza
I-PLC: -40°C kuya ku-85°C
I-FBT: -5°C kuya ku-75°C
8. Izindleko
Ngemva kokuba iShayina yenze intuthuko kubuchwepheshe be-chip ye-PLC, izindleko zamadivayisi e-PLC ziye zehla kancane kancane. Isibonelo, akusekho umehluko wezindleko phakathi kwama-splitter e-1×2 PLC kanye ne-1×2 FBT Coupler. Ngaphezu kwalokho, lapho inani lama-splitting ports liphezulu, kulapho inzuzo yentengo yama-splitter e-PLC iba nkulu khona.
Isiphetho
Nakuba ama-splitter e-FBT kanye ne-PLC optical angabelana ngesinyathelo sangaphandle esifanayo, ubuchwepheshe bawo obuyisisekelo kanye nemininingwane yokusebenza kuhluka kakhulu. Ukwethulwa kobuchwepheshe be-PLC kumele intuthuko enkulu emkhakheni, njengoba izimise njengesixazululo esinikeza ukuthembeka okuphezulu kune-splitter yendabuko ye-FBT. Kuzinhlelo zokusebenza ezifuna izilinganiso eziphezulu zokuhlukaniswa, usayizi omncane, kanye nokulahlekelwa okuphansi kokufakwa, i-splitter ye-PLC kufanele ibe inketho ekhethwayo.
