Fiber midhiya inoshandura inogona kukamurwa kuita imwe-modhi faibha uye yakawanda-modhi faibha zvinoenderana neiyo nzira yekufambisa mufiber. Musiyano wakanyanya kukosha pakati pe-single-modhi uye akawanda-modhi ndiyo yekufambisa kureba.

Indasitiri giredhi faibha media inoshandura: mutsauko uripo pakati peimwe-modhi faibha uye akawanda-modhi faibha:
(1) Single-mode fiber inoshandisa solid-state laser sechiedza sosi, uye multi-mode fiber inoshandisa light-emitting diode sechiedza sosi;
(2) Single-mode fiber ine yakakura yekufambisa frequency uye kureba kwekutapurirana chinhambwe, asi inoda laser sosi, iyo inodhura, uye multimode fiber ine yakaderera kutapurirana kumhanya, chinhambwe chipfupi uye mutengo wakaderera;
(3) Iyo dhayamita yepakati uye kupararira kwe-single-mode fiber idiki, uye imwe chete nzira yekutapurirana inobvumidzwa;
(4) Multimode fiber ine yakakura dhayamita yepakati uye kupararira, ichibvumira mazana emamodhi kuti afambiswe.
(5) Iyo fiber core ye multimode optical tambo yakakora, uye mutengo unodhura zvakanyanya.

Indasitiri-giredhi fiber midhiya inoshandura: mutsauko uripo pakati peimwe-modhi optical module uye yakawanda-modhi optical module:
(1) Iyo wavelength ye-multi-mode Optical module ndeye 850nm; single-mode Optical module ndeye 1310nm, 1550nm;
(2) Zvishandiso zvinoshandiswa mu-single-mode optical modules zvakapetwa kaviri zve-multi-mode optical modules, saka mari yose ye-single-mode optical modules yakakwirira kudarika ye-multi-mode optical modules;
(3) Iyo yekufambisa kureba kwe-single-mode optical modules inogona kusvika 100km; multi-mode optical modules inongova 2km.
