ST Wahine ki te tane attenuator

STte muka whatu attenuatorhe taputapu hāngū hei whakaiti i te kaha kaha o te tohu marama me te kore e tino huri i te ahua ngaru ake.Ko te nuinga o nga wa he whakaritenga tenei i roto i te Dense Wave Division Multiplexing (DWDM) me te Erbium Doped Fiber Amplifier (EDFA) tono kaore e taea e te kaiwhiwhi te whakaae ki te tohu i hangaia mai i te puna marama-kaha.

STkaiwhakahauhe momo motuhake o te muka doped whakarewa-katote e whakaiti ana i te tohu marama i a ia e haere ana.Ko tenei tikanga whakaheke ka taea te mahi teitei ake i nga hononga muka, i nga wehenga muka, i te waatea ranei o te muka, e mahi ana ma te pohehe, kaua ki te tango i te tohu marama.Ka taea e nga kaitautoko ST te mahi i roto i te 1310 nm me te 1550 nm mo te Aratau-kotahi me te 850nm mo te Aratau-maha.

STnga kaiwhakaterehe kaha ki te tu atu ki runga i te 1W o te maaramatanga marama hiko teitei mo nga wa roa, kia pai ai ki te EDFA me etahi atu tono mana nui.He iti te Polarization Dependent Loss (PDL) me te tohatoha roangaru pumau me te motuhake e pai ana mo te DWDM.
