Kuba izihluzi, njengayo nayiphi na enye imveliso eyenziwe ngumntu, azinakwenziwa ukuze zingqinelane ngqo neenkcukacha zencwadi, amanye amaxabiso avumelekileyo kufuneka axelwe. Kwizihluzi ze-narrowband, iiparameters eziphambili ekufuneka zinikwe ukunyamezela: ubude be-wavelength, i-peak transmittance, kunye ne-bandwidth, kuba phantse kuzo zonke izicelo eziphakamileyo zokugqithiswa kwe-peak kungcono, kwaye ngokuqhelekileyo kwanele ukuchaza umda ophantsi. Kwincopho yokunyamezela amaza kukho imiba emibini ephambili. Eyokuqala kukufana kwencopho yobude bobude obungaphezulu komphezulu wesihluzo. Kuya kuhlala kukho ukuhluka, nangona kuncinci kakhulu, kwifilimu, kodwa umda kufuneka unikwe. Okwesibini, imposiso ekulinganiseni i-avareji yobude be-avareji yobude bendawo yonke yesihluzi. Esi sibonelelo sikholisa ukuba silungile, ukuze isihluzi sisoloko sithambethekile ukuze silungelelanise ubude bobude obuchanekileyo. Kwi-bandwidth enikeziweyo, inani le-tilt evunyelwe kulo naliphi na isicelo liya kumiselwa kwinqanaba elikhulu ngobubanzi kunye nentsimi yembono yenkqubo, kuba njengoko i-angle ye-tilt inyuka, uluhlu olupheleleyo lwee-angles zesiganeko esinokuthi isihlunu singavuma siyancipha.
I-bandwidth yesihluzi kufuneka ichazwe kwaye inikwe isibonelelo, kodwa ngenxa yobunzima bokulawula i-bandwidth ngokuchanekileyo, ngokuqhelekileyo akunakwenzeka ukukhawulela i-bandwidth ngokungqongqo kakhulu, kwaye isibonelelo kufuneka sibe sibanzi kangangoko kunokwenzeka, ngokuqhelekileyo singabi ngaphantsi kwe-0.2 amaxesha exabiso elilinganisiweyo, ngaphandle kokuba kukho imfuneko ekhethekileyo kuyo.
Enye ipharamitha ebalulekileyo kwisalathisi sokusebenza kwe-optical yi-cutoff kwingingqi ye-cutoff, enokuthi ichazwe ngeendlela ezininzi ezahlukeneyo, mhlawumbi njenge-avareji yokudluliselwa phezu koluhlu olupheleleyo, okanye njengokudluliselwa okupheleleyo kulo lonke uluhlu kunoma yimuphi umda wamaza, zombini unokunika umda ophezulu. Eyokuqala idla ngokusetyenziswa xa umthombo wokuphazamiseka yimbonakalo eqhubekayo, okwesibini kumthombo womgca, apho i-wavelength esetyenzisiweyo, ukuba iyaziwa, kufuneka ichazwe.
Enye indlela eyahlukileyo yokuchaza usebenziso lwesihluzi kukucwangcisa ubuninzi kunye nobuncinci beimvulophu zotshintsho losasazo olunobude bewaveveve. kubalulekile ukuba i-angle yokwamkelwa kwesihluzi nayo kufuneka ichazwe. Olu hlobo lometriki lucace ngakumbi kunolokuqala lukhankanywe ngasentla, nangona kunjalo, enye intsilelo yale nkcazo yemetriki kukuba indlela ichaza ikhonkco ngalinye ngokwemiqathango epheleleyo, enokuthi ifuneke kakhulu xa usebenzisa ixabiso eliqhelekileyo linokuba lilungile. Ukuqhubela phambili, akunakwenzeka ukuyila uvavanyo ukugqiba ukuba isihluzi sidibana nolu hlobo lwe-metric epheleleyo, kwaye i-bandwidth elinganiselwe yesixhobo sokuvavanya iphelela ekubeni nefuthe. Ngoko ke, ukuba izihluzi ziza kuchazwa ngolu hlobo, kuyacetyiswa ukuba kufakwe inqaku lokuba ukusebenza kwesihluzo esichazwe kumyinge we-wavelength nganye yi-avareji yokusebenza kwizithuba ezithile. Ngokubanzi, iinkcazo zeemethrikhi ze-optical performance zenziwe ngesidingo esincinci se-subs ezongezelelweyo. Kuyo nayiphi na isicelo ezi zinto ziya kubonisa amanqanaba ahlukeneyo okubaluleka, kwaye imeko nganye kufuneka ithathelwe ingqalelo enkulu ngokweenjongo zabo Kucacile ukuba kule nkalo kubalulekile ukuba umsebenzi womyili wenkqubo udityaniswe ngokusondeleyo kunye nomyili wokucoca.
