Dukansu fiber guda ɗaya da na'urorin gani na fiber dual fiber na iya watsawa da karɓa. Tunda dole ne sadarwar biyu su iya aikawa da karɓa. Bambance-bambancen shi ne cewa fiber optic module guda ɗaya yana da tashar jiragen ruwa guda ɗaya kawai. Ana amfani da fasahar rarraba maɗaukakiyar wavelength (WDM) don haɗa nau'ikan karɓa da watsa tsayin raƙuman ruwa a cikin fiber guda ɗaya, tace ta hanyar tacewa a cikin tsarin gani, kuma a lokaci guda kammala watsa siginar gani na 1310nm da karɓar siginar gani na 1550nm, ko akasin haka. . Saboda haka, dole ne a yi amfani da na'urar a cikin nau'i-nau'i (ba shi yiwuwa a bambanta fiber tare da tsayin igiyoyin transceiver iri ɗaya).
Don haka, madaidaicin fiber Optical module yana da na'urar WDM, kuma farashin ya fi na na'urar gani na fiber dual. Tun da dual fiber Optical modules karɓa da karɓa a kan tashoshin fiber na gani daban-daban, ba sa tsoma baki tare da juna, sabili da haka ba sa buƙatar WDM, don haka raƙuman ruwa na iya zama iri ɗaya. Farashin yana da arha fiye da na fiber guda ɗaya, amma yana buƙatar ƙarin albarkatun fiber.
Dubi fiber Optical module da guda fiber Tantancewar module a zahiri suna da irin wannan tasiri, kawai bambanci shi ne cewa abokan ciniki iya zabar guda fiber ko biyu fiber bisa ga nasu bukatun.
Single fiber Optical module ya fi tsada, amma yana iya adana albarkatun fiber, wanda shine mafi kyawun zaɓi ga masu amfani da ƙarancin albarkatun fiber.
Dual fiber Optical module yana da arha sosai, amma yana buƙatar amfani da ƙarin fiber guda ɗaya. Idan albarkatun fiber sun wadatar, zaku iya zaɓar module fiber na gani na dual fiber.
