Sezvo mafirita, sezvimwe zvigadzirwa zvakagadzirwa nevanhu, asingagone kugadzirwa kuti aenderane nezvinodiwa nebhuku remanyuwari, mamwe mavaru anotenderwa anofanira kutaurwa. Kune mafirita e-narrowband, maparamita makuru anofanirwa kupihwa matenderi ndeaya: urefu hwemafungu, peak transmittance, uye bandwidth, nekuti muzvinenge zvese zvinoshandiswa kana peak transmittance yakakwira zviri nani, uye zvinowanzo kukwana kutaura muganho wayo wakaderera. Kune peak wavelength tolerance pane zvinhu zviviri zvikuru. Chekutanga kufanana kwepeak wavelength pamusoro pefirita. Pachagara paine musiyano, kunyangwe uri mudiki kwazvo, mufirimu, asi muganho unofanirwa kupihwa. Chechipiri, kukanganisa pakuyera avhareji yepeak wavelength pamusoro penzvimbo yese yefirita. Iyi mvumo inowanzo kuve yakanaka, kuitira kuti firita igone kugara yakatsveyamiswa kuti ienderane newavelength chaiyo. Kune bandwidth yakatarwa, huwandu hwekutsveyamiswa hunobvumirwa mune chero application huchatariswa zvakanyanya nedhayamita nenzvimbo yekuona yesystem, nekuti sezvo angle yekutsveyamisa ichiwedzera, huwandu hwese hwemakona echiitiko ayo firita inogona kugamuchira hunoderera.
Bandwidth yefirita inofanirawo kutsanangurwa uye kupihwa mukana, asi nekuda kwekuoma kwekudzora bandwidth nemazvo, hazvigoneke kuganhurira bandwidth zvakanyanya, uye mukana unofanirwa kunge wakakura sezvinobvira, kazhinji kwete pasi pe0.2 nguva yekukosha kwakayerwa, kunze kwekunge paine chinodiwa chakakosha pairi.
Chimwe chinhu chakakosha mu optical performance index i cutoff iri mu cutoff region, iyo inogona kutsanangurwa nenzira dzakasiyana-siyana, kungave seavhareji yekutumira pamusoro pe range yese, kana se absolute transmittance pamusoro pe range yese pane chero wavelength, zvese zvinogona kupa muganho wepamusoro. Yekutanga inowanzo shandiswa kana kwakabva kupindira kuri continuous spectrum, yechipiri kune line source, umo wavelength inoshandiswa, kana ichizivikanwa, inofanira kutaurwa.
Imwe nzira yakasiyana yekutaura mashandiro efirita ndeyekuronga maenvelopu epamusoro uye epasi ekusiyana kwekutumira newavelength. Mashandiro efirita haafanire kuwira kunze kwenzvimbo yakafukidzwa neenvelopu; zvakakosha kuti kona yekugamuchira yefirita itaurewo. Rudzi urwu rwemetric rwakajeka kupfuura rwekutanga rwataurwa pamusoro apa, zvisinei, chimwe chikanganiso chetsananguro iyi yemetric ndechekuti nzira yacho inotsanangura chinongedzo chega chega mumashoko akazara, izvo zvinogona kuve zvakaoma zvikuru kana uchishandisa avhareji yehuwandu ingave yakanaka. Uyezve, hazvigoneke kugadzira bvunzo yekuona kana firita ichisangana nerudzi urwu rwe absolute metric, uye bandwidth yakaganhurirwa yemudziyo wekuyedza inoguma yava nemhedzisiro. Naizvozvo, kana mafirita achizotsanangurwa nenzira iyi, zvinokurudzirwa kuti chinyorwa chibatanidzwe chekuti mashandiro efirita anotsanangurwa pawavelength yega yega iavhareji yekushanda pane dzimwe nguva. Kazhinji, tsananguro dzemaoptical performance metrics dzakaitwa pasina chikonzero chekuwedzera ma subs. Mukushandiswa kwese kwezvinhu izvi zvinoratidza kukosha kwakasiyana-siyana, uye nyaya yega yega inofanira kutariswa zvakanyanya maererano nezvinangwa zvayo. Zviri pachena kuti mundima iyi zvakakosha kuti basa remugadziri wehurongwa rive rakabatana zvakanyanya neremugadziri wefirita.
