Raws li kev sib tw polarization {{0} Taug kev ntawm kev sib tw / PM sib txuas ntawm cov qauv fiber ntau (cov polarization sib cais tau tiav los ntawm cov qauv tsim tseem ceeb hauv qab no:
PM fiber ntau cov hauv paus pib: PM fiber ntau siv cov qauv tshwj xeeb (piv txwv li kev cuam tshuam nrog Begefringk thiab ua rau lub xeev polarization yog kis tau raws qhov chaw ruaj axis.
Kev Directal Coupling Mechanialism: Siv cov txheej txheem ua ke ua ke, cov cladding / sensab ntawm ob lub PM cov cheeb tsam yog qhov chaw teeb ci ntawm cov cores. Los ntawm kev tswj hwm cov txheej txheem tapering (ntev thiab taper kaum (piv txwv li, 1: 9) ntawm lub teeb liab kho tshiab ntawm ob daim fibers tau ua tiav. Polarization Mathing: thaum lub sij hawm txuas, polarization axes ntawm ob lub ntsej muag ") kom ntseeg tau tias" qeeb Axis "lossis" Ceev Axis "lossis" nrawm nrawm dua li ntawm cov axis uas tsis muaj crosstalk raws cov orthogonal axis. Lub xeev polarization lub xeev ntawm cov kawg tso zis teeb tau sib xws nrog qhov teeb meem teeb.

Cov Hom Mainstream (cais los ntawm cov qauv / kev ua haujlwm)

1. Kev faib tawm los ntawm Polarization - tswj cov qauv fiber ntau
● Panda -} hom polarization {{} tswj cov ntawv tshaj: cov hom tshiab tshaj plaws. Nws cov ntoo khaub ncaws fiber -}} section sym្ sectionារ "qhov kev ntxhov siab" (zoo siab rau kev ntxhov siab Panda), ua rau muaj kev ntxhov siab ntawm kev ntxhov siab thiab kev ua haujlwm siab ntev (ib). Nws yog qhov haum rau feem ntau polarization -} Cov tshuab rhiab (xws li kev sib txuas lus fiber ntau thiab sib txuas lus).
● Bowlie - Hom Polarization Kev Siv Hluav Taws Xob: Nws yog qhov xav tau cov khoom siv hluav taws xob ntau dua), tab sis nws yog kim.
● Elliptical - clad polarization {} tswj cov cladding: Nws feem ntau yog siv nyob rau hauv cov tshuab yooj yim polarization hauv ib puag ncig kev lag luam.
2. Kev faib tawm los ntawm tus naj npawb ntawm cov chaw nres nkoj
● 2 × 2 polarization {{2} Cia li siv cov khoom lag luam ntxiv (piv txwv li ntawm ob qho kev ntsuas teeb liab, ua kom sib txuas ntawm ob qho).

● 1 × n Polarization {{1} Cia kev tswj hwm coupler (nqaj splitter (n output}}}}}}}}, ...). Tsuas siv rau kev faib tawm hluav taws xob (xws li thaum mus kuaj kom pom ntawm ntau cov cim hauv kev ntsuas kho qhov muag) thiab tsis muaj ko taw tiv thaiv kev ua haujlwm.

Xaiv thiab Siv Ntawv Siv

1. Nees xaiv kev xaiv:
● Ua ntej tshaj tawm cov "wavelach" (yuav tsum muaj kev sib xws nrog lub wavelength ntawm lub qhov system lub teeb ci hauv qhov chaw / ntes).
● Saib xyuas cov "Polarization extinction piv" raws li cov xwm txheej (kev sib txuas lus ntau dua lossis sib npaug nrog 25dB, ntau dua li 30db).
● Xaiv hom "chaw nres nkoj" raws li txoj haujlwm (2 × 2 rau faib / sib txuas, 1 × n rau cov nqaj sib cav xwb).
2.Cov ntawv sau ntawv:
●xeeb Polarization Axis Cov Axis Cliignment: Thaum sib txuas, ua kom cov qib polarization (piv txwv li cov pa thiab tawm cov kab ke. Txwv tsis pub, rau ib qho yuav ua rau poob qis (ib qho kev ua tsis raws cai 1 yuav ua rau 5-10dB poob rau hauv ib).
● Kev tswj hwm ib puag ncig: Tsis txhob muaj kev hloov kho tshuab hluav taws xob (sib npaug nrog cov fiber ntau dua lossis sib npaug ntawm cov neeg muaj kev ntxhov siab.
● Kev sib txuas tsis tau: Siv cov kev mob siab rau polarization {{} Kom muaj fc / apc- pm) kom txo qis polarization crosstalk thiab cov ntxig kev poob thaum lub sijhawm sib txuas.
