Zolumikizira za 32 Optic Fiber Amplifier 1550nm CWDM EDFA SC

Chiyambi Chachidule

Chojambulira cha ulusi wamagetsi cha 1550nm chimagwiritsa ntchito kukulitsa kwa magawo awiri, gawo loyamba limagwiritsa ntchito EDFA yopanda phokoso lotsika, ndipo gawo lachiwiri limagwiritsa ntchito EYDFA yamagetsi amphamvu kwambiri. Mphamvu yonse yotulutsa imatha kufika 41dBm. Ikhoza kusintha ma EDFA angapo kapena makumi ambiri, zomwe zingachepetse kwambiri mtengo womanga ndi kukonza maukonde, ndikuchepetsa malo akutsogolo. Doko lililonse lotulutsa limayika CWDM, multiplexing CATV signal ndi OLT PON data stream. Chipangizochi chidzakhala ndi gawo lofunika kwambiri pakukulitsa ndi kukulitsa kosalekeza kwa netiweki ya ulusi wamagetsi. Chimapereka yankho lokhazikika komanso lotsika mtengo la FTTH triple play ndi coverage ya malo akulu.
Cholowera cha ulusi wawiri chosankha chimaphatikiza makina onse osinthira kuwala, omwe angagwiritsidwe ntchito ngati chosungira njira zowunikira A ndi B. Njira yayikulu yowunikira ikalephera kapena ikagwa pansi pa malire, chipangizocho chidzasinthira chokha ku mzere wosungira kuwala kuti chitsimikizire kuti chipangizocho chikugwira ntchito mosalekeza. Chogulitsachi chimagwiritsidwa ntchito makamaka mu netiweki ya mphete ya ulusi wa kuwala kapena netiweki yosungira yowonjezera. Chili ndi nthawi yochepa yosinthira (< 8 ms), kutayika kochepa (< 0.8 dBm), komanso kusinthana kwamanja mokakamizidwa.
Posiya kugwiritsa ntchito mabatani, ili ndi chophimba cha LCD chamtundu wokhudza kwambiri komanso mawonekedwe anzeru apadera ogwiritsira ntchito. Zithunzi, zizindikiro, ndi kapangidwe kake n'zosavuta kumva, zomwe zimathandiza ogwiritsa ntchito kugwiritsa ntchito mosavuta komanso mosavuta. Zipangizo zopanda buku.
Zigawo zazikulu ndi ma laser apamwamba kwambiri a pampu ndi ulusi wochita kupanga wa double-clad. Kapangidwe ka njira yowunikira bwino komanso njira zopangira zimatsimikizira magwiridwe antchito abwino kwambiri a kuwala. APC yolamulidwa ndi electronically (Automatic Power Control), ACC (Automatic Current Control) ndi ATC (Automatic Temperature Control) zimatsimikizira kukhazikika kwakukulu ndi kudalirika kwa mphamvu yotulutsa, komanso magwiridwe antchito abwino kwambiri a kuwala.
Dongosololi limagwiritsa ntchito MPU (microprocessor) yokhala ndi kukhazikika kwakukulu komanso kulondola kwambiri. Kapangidwe kabwino ka kapangidwe ka kutentha komanso mpweya wabwino komanso kapangidwe ka kutentha kumaonetsetsa kuti zidazo zizikhala nthawi yayitali komanso kudalirika kwambiri. Kutengera ntchito yamphamvu yoyang'anira maukonde ya protocol ya TCP/IP, kuyang'anira maukonde ndi kuyang'anira mutu wa chipangizo cha ma node ambiri kumatha kuchitika kudzera mu mawonekedwe owongolera maukonde a RJ45, ndipo imathandizira makonzedwe angapo amagetsi ofunikira, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito komanso zothandiza. Kudalirika kwa zida.

Mawonekedwe
1. Pogwiritsa ntchito makina ogwiritsira ntchito a touch screen, amatha kuwonetsa zinthu zambiri kuphatikizapo index iliyonse mwatsatanetsatane komanso mwachilengedwe kuti ziwonekere bwino nthawi yomweyo, ntchito yosavuta, zomwe mukuwona ndi zomwe mumapeza, ogwiritsa ntchito amatha kugwiritsa ntchito chipangizocho mosavuta, komanso mosavuta popanda buku la malangizo.
2. Batani lokonza lomwe limatsitsa 6dB mwachangu limawonjezedwa ku menyu yayikulu. Ntchitoyi imatha kuchepetsa mwachangu 6dBm mu doko lililonse (≤18dBm output), ndipo imatha kupewa kuti ulusi wa chigambacho usawotchedwe ukalumikizidwa ndi kutuluka. Pambuyo pokonza, imatha kubwerera mwachangu momwe idagwirira ntchito.
3. Imagwiritsa ntchito laser yapamwamba kwambiri ya pampu ndi ulusi wogwira ntchito wopangidwa ndi double-cladding.
4. Doko lililonse lotulutsa limakhala ndi CWDM.
5. Yogwirizana ndi FTTx PON iliyonse: EPON, GPON, 10GPON.
6. Kapangidwe kabwino kwambiri ka APC, ACC, ATC, ndi AGC optical circuit kamatsimikizira phokoso lochepa, kutulutsa kwakukulu, komanso kudalirika kwakukulu kwa chipangizocho mu gulu lonse logwirira ntchito (1545 ~ 1565nm). Ogwiritsa ntchito amatha kusintha ntchito za APC, ACC, ndi AGC malinga ndi zosowa zawo zenizeni.
7. Ili ndi ntchito yoteteza yokha ngati chipangizocho chili ndi mphamvu zochepa kapena ngati sichinalowe. Mphamvu yowunikira ikatsika kuposa mtengo wokhazikitsidwa, laser imazima yokha kuti iteteze chitetezo cha chipangizocho.
8. Zotulutsa zosinthika, zosinthika: 0~-4dBm.
9. Mayeso a RF mu gulu lakutsogolo (ngati mukufuna).
10. Nthawi yosinthira ya switch ya optical ndi yochepa ndipo kutayika kwake ndi kochepa. Ili ndi ntchito zosinthira zokha komanso kusinthasintha kwamanja mokakamiza.
11. Mphamvu zamagetsi ziwiri zomangidwa mkati, zimasinthidwa zokha ndipo zimathandizidwa ndi pulagi yotentha.
12. Ma parameter ogwiritsira ntchito makina onse amayendetsedwa ndi microprocessor, ndipo chiwonetsero cha LCD cha mawonekedwe kutsogolo chili ndi ntchito zambiri monga kuyang'anira mawonekedwe a laser, chiwonetsero cha mawonekedwe, alamu yolakwika, kasamalidwe ka netiweki, ndi zina zotero; magawo ogwiritsira ntchito a laser akachoka pamlingo wololedwa womwe wakhazikitsidwa ndi
13. Mawonekedwe a RJ45 okhazikika amaperekedwa, othandizira kasamalidwe ka netiweki yakutali ya SNMP ndi WEB.
