1. Intangiriro muri make ya PLC optique itandukanya
Igice cya PLC nikintu cyahujwe na optique yo gukwirakwiza amashanyarazi ashingiye kuri quartz substrate.Igizwe ningurube, chip yibanze, fibre optique, ibishishwa (agasanduku ka ABS, imiyoboro yicyuma), umuhuza hamwe ninsinga za optique, nibindi. Ukurikije tekinoroji ya planar optique ya waveguide, ibyinjira bya optique bihindurwa mubisubizo byinshi bya optique muburyo bunoze bwo guhuza neza.
Ubwoko bwa planar waveguide optique itandukanya (PLC itandukanya) ifite ibiranga ubunini buto, uburebure bwumurongo mugari, kwizerwa cyane, hamwe no gutandukanya optique.Birakwiriye cyane cyane guhuza ibiro bikuru mumiyoboro ya optique (EPON, BPON, GPON, nibindi) nibikoresho bya terefone hanyuma ukamenya ishami ryibimenyetso bya optique.Hano hari ubwoko bubiri: 1xN na 2xN.1 × N na 2XN bitandukanya byinjiza kimwe ibimenyetso bya optique kuva kumurongo umwe cyangwa ibiri kumurongo umwe, cyangwa gukora muburyo bwo guhuza ibimenyetso byinshi bya optique mumibiri imwe cyangwa ibiri ya optique.
2. Imiterere ya fibre PLC itandukanya
Amahitamo ya optique ya PLC nimwe mubintu byingenzi bigize pasiporo ihuza optique ya fibre optique.Ifite uruhare runini muri FTTH passive optique.Nibikoresho bya optique fibre tandem ifite ibyinjira byinshi nibisohoka byinshi.Ibice bitatu byingenzi byingenzi ni iyinjiza ryanyuma, ibisohoka birangira hamwe na chip ya fibre optique.Igishushanyo noguteranya ibi bice bitatu bigira uruhare runini mukumenya niba PLC optique itandukanya ishobora gukora neza kandi mubisanzwe nyuma.
1) Iyinjiza / ibisohoka imiterere
Iyinjiza / isohoka imiterere ikubiyemo isahani yo gupfundikira, substrate, fibre optique, agace koroheje koroheje, hamwe nubutaka bukomeye.
Agace koroheje koroheje: Byakoreshejwe mugukosora fibre optique kumupfundikizo no hepfo ya FA, mugihe urinda fibre optique kwangirika.
Agace gakomeye: Kosora igifuniko cya FA, isahani yo hepfo hamwe na fibre optique muri V-groove.
2) chip ya SPL
Chip ya SPL igizwe na chip hamwe nisahani.Ukurikije umubare winjiza nibisohoka, mubisanzwe bigabanyijemo 1 × 8, 1 × 16, 2 × 8, nibindi. Ukurikije inguni, ubusanzwe igabanyijemo + 8 ° na -8 ° chip.
3. Tekinoroji yo kubyaza umusaruro optique ya PLC
Gutandukanya PLC bikozwe na tekinoroji ya semiconductor (lithographie, etching, iterambere, nibindi).Optical waveguide array iherereye hejuru ya chip, kandi imikorere ya shunt ihujwe kuri chip.Nukumenya 1: 1 kunganya kugabana kuri chip.Hanyuma, iyinjiza ryanyuma nibisohoka birangirira kumirongo myinshi ya optique fibre array ihujwe kumpande zombi za chip hanyuma ipakirwa.
