1. Gulu laFiberAmplifaers
Pali mitundu itatu yayikulu ya Emplifiers
.
(2) A Nthawi Zomwe Otsanzira Amakhala Ndi Zinthu Zapadziko Lonse Lapansi (Erbium Er, Trulium TM, Praseodmium PR, Rubidium ND ErbiumEdfa), komanso mitsuko ya Amplium-Duldeers (TDFA) ndi Prageymium-Draedmium-Draedmium-Draped Ammpuders (PDFA), etc.
. Kuyerekezera kwakukulu kwa omwe akuwaza awa akuwoneka bwino patebulo
EDFA (Ebium dopded fish Amplifari)
Dongosolo la laseji la laseri lomwe limatha kupangidwa ndi kutsika ndi quartz ndi zinthu zamtundu wina padziko lapansi (monga ND, ER, ER, TM, ndi Sc.) Kuwala kwa Kuwala. Nditapereka ndemanga zoyenera, laser ya fiber inapangidwa. Kugwira ntchito kwamphamvu kwa amplifier ndi 1060nm ndi 1330nm, ndipo chitukuko chake ndi ntchito zake ndizochepa pakuyankhulana bwino ndi ziwonetsero zopambana za fiber ndi zifukwa zina. Makina ogwiritsira ntchito Edfa ndi PDFA akutsata pazenera lotsika kwambiri (1550nm) ndi zero zowonjezera zithunzi zam'madzi, ndipo TDFA imagwira ntchito mu s-band yolumikizira Phatikizani. Makamaka Edfa, chitukuko chachangu kwambiri, chakhala chothandiza.
APkachika cha edfa
Kapangidwe koyambirira kwa Edfa kumawonetsedwa pa Chithunzi 1 (a), omwe amapangidwa ndi silika ya erbium ya mamita pafupifupi 3-5), kapazi kopepuka (990 kapena 1480nm ndi owoneka bwino Kuwala kowala ndi pampu kumatha kufalitsa mbali yomweyo (kupompa pamapamputikidwe), mayendedwe ake (onjezerani kupopa) kapena kupopera mayendedwe (polowera) munjira ya erbium. Kuwala kwamanja ndi kuwala kwa kayendedwe kamalowetsedwa mu erbium nthawi yomweyo, ma erbium ions amasangalala kwambiri ndi kuwala kwa pompopompo, ndikuwola kwamphamvu kwambiri. Chithunzi 1 (c) Kodi amakuthandizani)
Ubwino waukulu wa Edfa ndi phindu lalikulu, gulu lalikulu la bandwidth, mphamvu yayikulu kwambiri, kuchepa kwapadera, komanso kusayanjanitsa dziko.
2. Vuto ndi Amplif Amplifete
Ngakhale opatulitsira mawu (makamaka edfa) ali ndi zabwino zambiri, siwothandiza. Kuphatikiza pa phokoso lina lomwe limachepetsa snr ya chizindikirocho, pali zina zophophonya, monga:
- Kusagwirizana kwa kuchuluka kwa mawonekedwe mkati mwa amplifier bandwidth amakhudza magwiridwe antchito osiyanasiyana;
- Pamene Amplifecal Amphuce akasokonekera, zovuta za asee phokoso, chimbani chofatsa komanso zotsatira zosagwirizana zimapezeka.
Nkhanizi ziyenera kuganiziridwa mu ntchito ndi kapangidwe kake.
3. Kugwiritsa ntchito makope owoneka bwino mu njira yolankhulira
M'makanema a Purtebulo, njira yolankhulirana,Amplive Optive OpsiterItha kugwiritsidwa ntchito osati ngati mphamvu yolimbikitsa yomasulira kuti iwonjezere mphamvu yolandila magetsi, komanso imathanso kusinthanitsa ndi magetsi oyendetsa magetsi, kuti azindikire mtunda wowonjezera.
M'makanema owonetsera makonda, zinthu zazikulu zomwe zimalepheretsa mtunda ndikutayika ndikugawika fiber. Pogwiritsa ntchito gwero lopapatiza-pepani, kapena kugwira ntchito pafupi ndi zilombo zamimba, chipwirikiti chiberekero chimakhala chochepa. Dongosolo lino silifunikira kuchita zonse zomwe zimabwezeretsanso nthawi ya 3r (10r) pamayendedwe aliwonse. Ndikokwanira kukulitsa mwachindunji chizindikiro chowoneka bwino ndi mawonekedwe owoneka bwino (1R chivomerezi). Makina owoneka owoneka satha kugwiritsidwa ntchito osati njira zazitali komanso m'matumba a masamba a masamba, makamaka mu ma wdm, kuwonjezera njira zingapo nthawi imodzi.
1) Kugwiritsa ntchito amplifas owoneka bwino mu thunthu
Mkuyu. 2 ndi chithunzi chachilendo cha kugwiritsa ntchito kwa Empniffier mu thunthu lomwe lingachitike. . Mwachitsanzo, kutengera EDFA, kutumiza kachitidwe ka kachitidwe Kutali kwa 1.8GB / S kumawonjezeka kuchokera pa 120km mpaka 250km kapena kufikira 400km. Chithunzi 2 (b) - (D) ndi kugwiritsa ntchito kwa arkisiers owoneka bwino m'magulu angapo; Chithunzi (B) ndi njira yachikhalidwe ya 3r; Chithunzi (c) ndi njira yosakanikirana ya 3r Retaters ndi Amplifiers Omprive; Chithunzi 2 (d) ndi njira yolumikizira; Mu njira yolumikizirana konse, simaphatikizapo madera ozungulira nthawi ndi kubwezeretsanso, motero sizachilendo, ndipo palibe magwero am'maso "oletsa. Malingana ngati kutumiza ndi kulandira zida kumapeto kuli m'malo mwake, ndikosavuta kukweza pang'ono mpaka pamlingo waukulu, ndipo ampukuwa sayenera kusinthidwa.
2) Kugwiritsa ntchito kwa amplifar optable mu netiweki yogawa
Mphamvu yayikulu yotulutsa mawu onjezerani makope owoneka bwino (makamaka edfa) ndizothandiza kwambiri pa network zowonjezera (mongaNyamaMaukonde). Ma network a ku Catv amatengera chingwe cholunjika, chomwe chikufunika kuti chikudzolitsidwa mamita mazana angapo, ndipo radius ya ntchito ya netiweki ili pafupifupi 7km. Chitsamba cham'madzi chojambulajambula pogwiritsa ntchito amplifesi sichongowonjezera kuchuluka kwa ogwiritsa ntchito omwe amagawidwa, komanso akukula kwambiri pa intaneti. Zomwe zidachitika posachedwa zawonetsa kuti kufulutsidwa kwa fiber / hybrid (HFC) kumakoka mphamvu za onse komanso kuli ndi mpikisano wamphamvu.
Chithunzi 4 ndichitsanzo cha mapepala oyeserera a Putric Putrict a Am-vsb kusintha kwa mayendedwe 35 a TV. Kuwala kwa transtiration ndi dfb-ld ndi chiwongolankhulidwa ndi 1550nm ndi mphamvu yotulutsa ya 3.3dbm. Pogwiritsa ntchito edfa 4-Edfa ngati asanagawire mphamvu, mphamvu zake zakhudza -6dbm, ndipo mphamvu yake yotulutsa ili pafupifupi 13dbm. Wolandila mawu omvera -9.2d bm. Pambuyo 4 magawo a magawidwe, kuchuluka kwathunthu kwa ogwiritsa ntchito kwafika 4.2 miliyoni, ndipo njira ya netiweki imaposa makilomenti makumi. Chiwerengero cha mayeso oyenerera sichinali chachikulu kuposa 45db, ndipo Edfa sanayambitse kutsika kwa CSO.
