  • Yana iya kamuwa da "shiga" (hayaniyar shigar da kebul) da kuma "fita" (zubar sigina).

5. Tsaro

• Fiber na gani:

  • Yana da matuƙar wahala a taɓa ba tare da an gano shi ba (ana iya ganin katsewar haske).

  • Ya dace da watsa bayanai mai aminci (misali, gwamnati, kuɗi).

• Kebul na Coaxial:

  • Yana da sauƙin sauraron sauti ta hanyar leaking na lantarki ko famfo na zahiri.

  • Yana buƙatar ɓoye bayanai (misali, AES) don bayanai masu mahimmanci.

6. Kudin

• Fiber na gani:

  • Babban farashi a gaba(shigarwa, na'urorin watsawa, kayan aikin haɗawa).

  • Rage farashi na dogon lokaci (ƙarancin gyara, tabbatar da hakan a nan gaba).

• Kebul na Coaxial:

  • Shigarwa mai rahusa(akwai wadatattun masu haɗawa kamar nau'in F).

  • Gyara mafi girma akan lokaci (lalacewar sigina, gyaran kariyar kariya).

7. Dorewa da Girma

• Fiber na gani:

  • Gilashin da ke da rauni(yana buƙatar kulawa da kyau yayin shigarwa).

  • Sirara, mai sauƙin ɗauka, kuma mai sassauƙa (ya dace da bututun ruwa masu cunkoso).

• Kebul na Coaxial:

  • Karaƙarfi ta jikiamma mai kauri da nauyi.

  • Yana iya yin tsatsa idan jaket ɗin waje ya lalace.

8. Aikace-aikace

• Fiber na gani:

  • Sadarwar nesa mai nisa (Bayanan ISP, kebul na ƙarƙashin teku).

  • Intanet mai sauri (FTTH), cibiyoyin bayanai, da hanyoyin sadarwa na 5G.

  • Tsarin daukar hoton likitanci, tsarin soja, da na masana'antu.

• Kebul na Coaxial:

  • Talabijin na USB (CATV) da intanet mai sauri (misali, DOCSIS).

  • Kula da bidiyo na ɗan gajeren lokaci (CCTV).

  • Tsarin sadarwa na gargajiya (Ethernet ta hanyar coax) da eriya na rediyo.

9. Lalacewa

• Fiber na gani:

  • Ƙananan jinkirin jinkiri(kusa da watsawa mai saurin haske).

  • Yana da mahimmanci ga aikace-aikacen lokaci-lokaci (wasanni, cinikin hannun jari).

• Kebul na Coaxial:

  • Lalacewa mafi girma saboda jinkirin yaɗuwar siginar lantarki.

10. Watsa Wutar Lantarki

• Fiber na gani:

  • Ba za a iya watsa wutar lantarki ba; na'urori suna buƙatar hanyoyin samar da wutar lantarki daban.

• Kebul na Coaxial:

  • Tallafiwatsa wutar lantarki(misali, na'urorin ƙara ƙarfin lantarki a cikin tsarin CATV).

Yaushe Ya Kamata A Zaɓa Wanne?

• Fiber na gani:

  • Ana buƙatar yanayi mai matuƙar gudu, nesa mai nisa, ko kuma yanayin EMI mai nauyi.

  • Cibiyoyin sadarwa masu kare gaba (misali, biranen wayo, IoT).

  • Aikace-aikace da ke buƙatar babban tsaro da aminci.

• Kebul na Coaxial:

  • Saitunan da suka dace da kasafin kuɗi (misali, talabijin na kebul na gida/intanet).

  • Tsarin sa ido na bidiyo na ɗan gajeren lokaci (CCTV) ko tsarin da aka saba amfani da shi.

  • Hanyoyin sadarwa na fiber-coaxial (HFC) masu haɗaka (wanda aka saba gani a cikin ISPs na kebul).

Abubuwan da ke Faruwa a Nan Gaba

• Fiber na ganiAmfani da fasahar 5G, ayyukan girgije, da kayayyakin more rayuwa masu wayo yana hanzarta.

• Kebul na coaxialsuna da mahimmanci ga hanyoyin sadarwa na HFC da tsarin gado amma a hankali ana cire su daga tsarin don amfani da zare.

Kammalawa:
Kebulan fiber optic sun yi fice a gudu, nisa, da kuma aminci, wanda hakan ya sa suka dace da aikace-aikacen zamani masu yawan buƙata. Kebulan coaxial suna da inganci ga tsarin gajere, na gado, ko na haɗaka amma suna fama da ƙarancin bandwidth da tsangwama. Zaɓin ya dogara ne da kasafin kuɗin ku, buƙatun fasaha, da kuma burin haɓaka.
