b. Fiber Yanayin Yawa (MMF)
Yanayin aiki da yawa yana da babban tsakiya (microns 50/62,5) kuma yana ba da damar yanayin haske da yawa. Gabaɗaya ana amfani da shi don gajerun nesa zuwa matsakaici.
Kelebihan:
- Farashin na'urorin gani ya fi araha fiye da yanayin guda ɗaya
- Ya dace da hanyoyin sadarwa na cikin gida ko harabar jami'a
Kekurangan:
- Tazara mafi guntu fiye da SMF saboda watsawa ta hanyar zamani
- Ba shi da kyau don haɗin nesa mai nisa
Misalan amfani:
- Cibiyar bayanai, cibiyar sadarwa ta harabar jami'a, haɗi tsakanin rakodin uwar garken
Fiber optics gabaɗaya suna amfani da masu haɗawa kamar SC, LC, ST, ko MPO/MTP don buƙatun yawan bayanai masu yawa.
4. Kebul na Tagulla don Sadarwar Gargajiya (Wayar Waya/Wayar Saukewa)
Kafin intanet ta fiber-optic ta yaɗu, wayoyin jan ƙarfe sun yi aiki a matsayin ginshiƙin ayyukan waya da DSL. Waɗannan wayoyin na iya ƙunsar nau'i-nau'i da yawa a cikin babban fakiti ɗaya.
Kelebihan:
– Kayayyakin more rayuwa suna da yawa kuma an daɗe ana amfani da su
- Ana iya amfani da shi har yanzu don wayoyin analog ko ADSL/VDSL
Kekurangan:
- Iyakantaccen bandwidth idan aka kwatanta da fiber
- Siginar ta faɗi sosai a cikin dogon nisa
– Yana iya shiga cikin tsangwama da tsatsa idan an shigar da shi ba daidai ba
Misalan amfani:
– Kebul ɗin wayar ƙasa, hanyoyin sadarwar PSTN, ADSL/VDSL
5. Kebul ɗin Ribbon da Kebul ɗin Fiber Mai Yawan Kauri
Yayin da buƙatun ƙarfin aiki ke ƙaruwa, masu aiki da yawa suna amfani da kebul na fiber mai yawan tsakiya ko ribbon fiber don hanzarta haɗin kai.
Kelebihan:
- Babban iya aiki a cikin kebul ɗaya
- Inganci don tushen tushe da cibiyar bayanai
- Yana hanzarta shigarwa idan ana amfani da hanyar haɗawa ta musamman

Kammalawa
Akwai nau'ikan kebul daban-daban a cikin sadarwa, kowannensu yana da nasa ayyuka da fa'idodi. Nau'in Twisted pair (UTP/STP) ya fi kyau ga hanyoyin sadarwa na gida da kuma sauƙin shigarwa. Kebul na coaxial yana da ƙarfi a cikin RF da wasu ayyuka kamar talabijin na kebul. Duk da haka, kebul na fiber optic shine babban zaɓi yanzu da kuma nan gaba saboda babban bandwidth ɗinsa, nisa mai nisa, da juriya ga tsangwama. Bugu da ƙari, kebul na ciyarwa da jagororin raƙuman ruwa suna da mahimmanci a cikin kayan aikin salula da na microwave.
Zaɓar kebul mai dacewa yana buƙatar la'akari da buƙatun bandwidth, nisa, yanayin shigarwa, farashi, da sauƙin kulawa. Fahimtar halaye na kowane nau'in kebul na iya taimakawa wajen gina hanyar sadarwa ta sadarwa cikin inganci, kwanciyar hankali, da kuma shirya shi don ƙaruwar buƙatun bayanai a nan gaba.
Idan kana so, zan iya ƙara teburin kwatantawa (bandwidth, nisa, farashi, da amfani) ko kuma daidaita wannan labarin don ayyukan makaranta/kwaleji tare da tsarin ambato.
