1. Chiyambi chachidule cha PLC kuwala kogawa
Chigawo cha PLC splitter ndi chipangizo chogawa mphamvu zamagetsi cholumikizidwa ndi mafunde chozikidwa pa gawo la quartz. Chili ndi michira ya nkhumba, ma core chips, ma optical fiber arrays, zipolopolo (mabokosi a ABS, mapaipi achitsulo), zolumikizira ndi zingwe zamagetsi, ndi zina zotero. Kutengera ukadaulo wa mafunde amagetsi opangidwa ndi planar, cholowetsa cha kuwala chimasinthidwa kukhala zotulutsa zambiri zamagetsi mofanana kudzera mu njira yolumikizira yolondola.
Chogawaniza cha mtundu wa Planar waveguide (PLC splitter) chili ndi mawonekedwe aang'ono, kutalika kwa mafunde ogwirira ntchito, kudalirika kwakukulu, komanso kufanana kwabwino kwa kuwala. Ndikoyenera kwambiri kulumikiza ofesi yayikulu mu ma network osagwira ntchito (EPON, BPON, GPON, ndi zina zotero) ndi zida zolumikizira ndikuzindikira nthambi ya chizindikiro cha kuwala. Pakadali pano pali mitundu iwiri: 1xN ndi 2xN. Chogawaniza cha 1×N ndi 2XN chimalowetsa zizindikiro za kuwala kuchokera ku malo olowera amodzi kapena awiri kupita ku malo angapo otulutsira, kapena chimagwira ntchito motsatizana kuti chigwirizane ndi zizindikiro zambiri za kuwala kukhala ulusi umodzi kapena iwiri.
2. Kapangidwe ka chogawanitsa cha fiber PLC
Chogawaniza cha optical PLC ndi chimodzi mwa zigawo zofunika kwambiri passive mu ulalo wa fiber optical. Chimagwira ntchito yofunika kwambiri mu netiweki ya FTTH passive optical. Ndi chipangizo cha optical fiber tandem chokhala ndi ma input end angapo ndi ma output end angapo. Zigawo zake zitatu zofunika kwambiri ndi input end, output end ndi chip ya optical fiber array. Kapangidwe ndi kusonkhana kwa zigawo zitatuzi kumachita gawo lofunikira kwambiri pakuwona ngati PLC optical splitter ingagwire ntchito bwino komanso nthawi zonse pambuyo pake.
1) Kapangidwe ka zolowetsa/zotulutsa
Kapangidwe ka zolowetsa/zotulutsa kamakhala ndi mbale yophimba, substrate, ulusi wowala, malo ofewa a guluu, ndi malo olimba a guluu.
Malo ofewa a guluu: Amagwiritsidwa ntchito kumangirira ulusi wa kuwala ku chivundikiro ndi pansi pa FA, pomwe amateteza ulusi wa kuwala kuti usawonongeke.
Malo olimba a guluu: Konzani chivundikiro cha FA, mbale yapansi ndi ulusi wa kuwala mu V-groove.
2) Chipu cha SPL
Chip ya SPL imakhala ndi chip ndi mbale yophimba. Malinga ndi kuchuluka kwa njira zolowera ndi zotulutsira, nthawi zambiri imagawidwa m'magulu 1×8, 1×16, 2×8, ndi zina zotero. Malinga ndi ngodya, nthawi zambiri imagawidwa m'magulu 1×8° ndi -8°.
3. Ukadaulo wopanga wa optical PLC splitter
Chogawanitsa cha PLC chimapangidwa ndi ukadaulo wa semiconductor (lithography, etching, development, etc.). Optical waveguide array ili pamwamba pa chip, ndipo ntchito ya shunt imaphatikizidwa pa chip. Izi zikutanthauza kuti kugawanika kofanana kwa 1:1 pa chip. Kenako, mapeto olowera ndi mapeto otuluka a multi-channel optical fiber array amalumikizidwa motsatana kumapeto onse a chip ndikupakidwa.
