Chii chinonzi single-mode fiber uye multi-mode fiber?

Faibha yemhando imwe chete (Single-mode fiber), chiedza chinopinda mufiber nekona chaiyo yechiitiko uye kubuda kwakakwana kunoitika pakati pefiber necladding. Kana dhayamita iri diki, chiedza chinongobvumidzwa kupfuura nedivi rimwe chete, iro riri single-mode fiber; single-mode fiber; Modal fibers dzine girazi repakati rakatetepa, rinowanzova 8.5 kana 9.5 mm mudhayamita. mm mudhayamita, uye inoshanda pahurefu hwemafungu e1310 ne1550 nm.

Multimode fiber imhando yefiber faibha iyo inobvumira kutapurirana kwemaitiro akawanda anotungamirirwa. Dhayamita yepakati yefiber ye multimode inowanzova 50 mm/62,5 mNekuda kwehukuru hwepakati hwefiber ye multimode, chiedza chemhando dzakasiyana chinogona kutapurirwa mukati mefiber imwe chete. Mawavelength akajairwa efiber ye multimode i850 nm uye 1300 nm, zvichiteerana. Kunewo standard itsva ye multimode fiber inonzi WBMMF (Wideband Multimode Fiber), iyo inoshandisa wavelengths iri pakati pe850 nm ne953 nm.

Fiber yemhando imwe chete uye fiber yemhando dzakawanda, dzose dzine dhayamita ye125 mm.
