Ekubeni izihluzi, njengayo nayiphi na imveliso eyenziwe ngumntu, zingenakwenziwa ukuze zihambelane ngokuchanekileyo nemigaqo yencwadi yemiyalelo, kufuneka kuchazwe amaxabiso athile avumelekileyo. Kwiizihluzi ze-narrowband, iiparameter eziphambili ekufuneka zinikwe ukunyamezelana zezi: ubude be-peak, ukuhanjiswa kwe-peak, kunye ne-bandwidth, kuba phantse kuzo zonke izicelo apho ukuhanjiswa kwe-peak kuphezulu kungcono, kwaye kudla ngokwanela ukuchaza umda wayo ophantsi. Kwi-peak wavelength tolerance kukho iinkalo ezimbini eziphambili. Eyokuqala kukufana kwe-peak wavelength phezu komphezulu wesihluzi. Kuya kuhlala kukho umahluko, nangona umncinci kakhulu, kwifilimu, kodwa umda kufuneka unikwe. Okwesibini, impazamo ekulinganiseni ubude be-peak wavelength obuphakathi kuyo yonke indawo yesihluzi. Esi sibonelelo sihlala silungile, ukuze isihluzi sihlale sithambekile ukuze silungele ubude be-wavelength obuchanekileyo. Kwi-bandwidth ethile, ubungakanani bokuthambekela obuvunyelweyo kuyo nayiphi na isicelo buya kugqitywa kakhulu bububanzi kunye nebala lokujonga kwenkqubo, kuba njengoko i-angle yokuthambekela isanda, uluhlu olupheleleyo lwee-engile zeziganeko ezinokuzamkelwa sisihluzi luyancipha.
I-bandwidth yesihluzo nayo kufuneka ichazwe kwaye inikwe isibonelelo, kodwa ngenxa yobunzima bokulawula i-bandwidth ngokuchanekileyo, akunakwenzeka ukunciphisa i-bandwidth ngokungqongqo kakhulu, kwaye isibonelelo kufuneka sibe banzi kangangoko, ngokubanzi kungabi ngaphantsi kwe-0.2 yexabiso elilinganisiweyo, ngaphandle kokuba kukho imfuneko ekhethekileyo yalo.
Enye iparameter ebalulekileyo kwi-optical performance index yi-cutoff kwindawo ye-cutoff, enokuchazwa ngeendlela ezahlukeneyo, nokuba yi-avareji transmittance kulo lonke uluhlu, okanye njenge-absolute transmittance kulo lonke uluhlu kuyo nayiphi na i-wavelength, zombini ezinokuthi zinike umda ophezulu. Eyokuqala idla ngokusetyenziswa xa umthombo wokuphazamiseka uyi-spectrum eqhubekayo, eyesibini iye kumthombo womgca, apho ke i-wavelength esetyenzisiweyo, ukuba iyaziwa, kufuneka ichazwe.
Enye indlela eyahlukileyo yokuchaza ukusebenza kwesihluzi kukucwangcisa ii-envelopes eziphezulu nezincinci zotshintsho lokudluliselwa kombane nge-wavelength. Ukusebenza kwesihluzi akufuneki kuwele ngaphandle kommandla ogqunywe yi-envelope; kubalulekile ukuba i-engile yokwamkelwa kwesihluzi nayo ichazwe. Olu hlobo lwe-metric lucacile ngakumbi kunelokuqala elikhankanyiweyo apha ngasentla, nangona kunjalo, enye intsilelo yale nkcazo ye-metric kukuba indlela ichaza ikhonkco ngalinye ngokwemigaqo epheleleyo, enokuba nzima kakhulu xa kusetyenziswa ixabiso eliphakathi linokuba lilungile. Ngaphezu koko, akunakwenzeka ukuyila uvavanyo lokumisela ukuba isihluzi siyahlangabezana na nolu hlobo lwe-metric epheleleyo, kwaye i-bandwidth encinci yesixhobo sovavanyo igqibela inesiphumo. Ke ngoko, ukuba izihluzi ziza kuchazwa ngale ndlela, kucetyiswa ukuba kufakwe inqaku lokuba ukusebenza kwesihluzi okuchazwe kwi-wavelength nganye yi-avareji yokusebenza ngamaxesha athile. Ngokubanzi, iinkcazo ze-optical performance metrics zenziwe ngaphandle kwesidingo se-subs ezongezelelweyo. Kuyo nayiphi na indlela enye yokusebenza ezi zinto ziya kubonisa ukubaluleka okwahlukeneyo, kwaye imeko nganye kufuneka iqwalaselwe kakhulu ngokweenjongo zayo. Kucacile ukuba kule nkalo kubalulekile ukuba umsebenzi womyili wenkqubo udityaniswe ngokusondeleyo nowomyili wezihluzi.
