Izintambo ze-fiber optic kanye ne-coaxial zombili zisetshenziselwa ukudlulisa idatha, kodwa zihluke kakhulu ngomklamo, ukusebenza, kanye nezinhlelo zokusebenza. Nasi ukuqhathanisa okuningiliziwe:

1. I-Transmission Medium

• I-Fiber Optic:

  • Ukusetshenziswaukushaya kokukhanya(ama-laser/ama-LED) adluliselwa ngemicu yengilazi/yepulasitiki.

  • Idatha ihamba nge-ukubonakaliswa kwangaphakathi okupheleleenkabeni.

• Ikhebula le-Coaxial:

  • Ukusetshenziswaizimpawu zikagesingokusebenzisa umongo wethusi ozungezwe ukuvikela nokuvikela.

  • Iqukethe umqhubi ophakathi, isivikelo se-dielectric, isivikelo sensimbi, kanye nejakethi yepulasitiki yangaphandle.

2. Isivinini kanye ne-bandwidth

• I-Fiber Optic:

  • Isivinini: Kuya kuama-terabits ngomzuzwana (ama-Tbps)ocwaningweni; isekela i-100+ Gbps ngokwezentengiselwano.

  • Ububanzi bomkhawulo: Cishe ayinamkhawulo ngenxa yemvamisa ephezulu yokukhanya.

• Ikhebula le-Coaxial:

  • Isivinini: Ngokuvamile kuze kufike ku-10 Gbps(isb., i-DOCSIS 4.0 ye-inthanethi yekhebula).

  • Ububanzi bomkhawulo: Kunqunyelwe ukuncishiswa kwesignali kumaza aphezulu (kufika ku-1 GHz ku-coax yesimanje).

3. Ukulahlekelwa Ibanga Nesignali

• I-Fiber Optic:

  • Ibanga: I-fiber yemodi eyodwa (i-SMF) ingadluliselaAmakhilomitha angu-70–100+ngaphandle kweziphindaphindi.

  • Ukuncipha: Kuphansi kakhulu (~0.2 dB/km).

• Ikhebula le-Coaxial:

  • Ibanga: Kunqunyelwe ku-~amamitha angu-500(nge-RG-6 esezingeni eliphezulu) ngaphambi kokuwohloka kwesiginali.

  • Ukuncipha: Ukulahlekelwa okukhulu ngenxa yebanga, ikakhulukazi uma ushayela kakhulu.

4. Ukuphazamiseka Nokuthembeka

• I-Fiber Optic:

  • Ukungavikeleki ku-ukuphazamiseka kwe-electromagnetic (EMI)kanye nokuphazamiseka kwe-radio-frequency (RFI).

  • Akukho ukukhuluma noma ukuvuza kwesignali.

• Ikhebula le-Coaxial:

  • Umklamo ovikelwe wehlisa i-EMI/RFI kodwaamasosha omzimba(isib. ukuphazamiseka okuvela ezintanjeni zikagesi).

  • Ingangena kalula (umsindo ongena kukhebula) kanye "nokuphuma" (ukuvuza kwesiginali).

5. Ukuphepha

• I-Fiber Optic:

  • Kunzima kakhulu ukukuthinta ngaphandle kokubona (ukuphazamiseka kokukhanya kuyabonakala).

  • Kulungele ukudluliswa kwedatha okuphephile (isib. uhulumeni, ezezimali).

• Ikhebula le-Coaxial:

  • Kusengozini yokulalela ngokuvuza kwe-electromagnetic noma ukupompa okungokoqobo.

  • Kudinga ukubethela (isb., i-AES) kwedatha ebucayi.

6. Izindleko

• I-Fiber Optic:

  • Izindleko eziphezulu kusengaphambili(ukufakwa, ama-transceivers, amathuluzi okuhlanganisa).

  • Izindleko eziphansi zesikhathi eside (ukulungiswa okuncane, okungamelana nekusasa).

• Ikhebula le-Coaxial:

  • Ukufakwa okushibhile(zitholakala kabanzi, izixhumi ezilula njengohlobo lwe-F).

  • Ukugcinwa okuphezulu ngokuhamba kwesikhathi (ukuwohloka kwesignali, ukulungiswa kwesivikelo).

7. Ukuqina Nobukhulu

• I-Fiber Optic:

  • Ingqimba yengilazi ebuthakathaka(kudinga ukuphathwa ngokucophelela ngesikhathi sokufakwa).

  • Mncane, ulula, futhi uguquguqukayo (ulungele imisele enabantu abaningi).

• Ikhebula le-Coaxial:

  • Okuningiukuqina ngokomzimbakodwa likhulu futhi lisinda.

  • Kuthambekele ekugqwaleni uma ijazi langaphandle lonakele.

8. Izicelo

• I-Fiber Optic:

  • I-telecom ekude (i-backbone ye-ISP, izintambo ezingaphansi kolwandle).

  • I-inthanethi eshesha kakhulu (FTTH), izikhungo zedatha, amanethiwekhi e-5G.

  • Izinhlelo zezithombe zezokwelapha, ezempi, kanye nezezimboni.

• Ikhebula le-Coaxial:

  • I-Cable TV (CATV) kanye ne-inthanethi ye-broadband (isib. i-DOCSIS).

  • Ukuqapha ividiyo okude (i-CCTV).

  • Ukuxhumana kwenethiwekhi kwakudala (i-Ethernet phezu kwe-coax) kanye nama-antenna omsakazo.

9. Ukubambezeleka

• I-Fiber Optic:

  • Ukubambezeleka okuphansi(eduze kokudluliselwa kwejubane lokukhanya).

  • Kubalulekile kakhulu ezinhlelweni zokusebenza zesikhathi sangempela (imidlalo, ukuhweba ngamasheya).

• Ikhebula le-Coaxial:

  • Ukubambezeleka okuphezulu ngenxa yokubambezeleka kokusabalala kwesignali kagesi.

10. Ukudluliselwa Kwamandla

• I-Fiber Optic:

  • Ayikwazi ukudlulisa amandla kagesi; amadivayisi adinga imithombo yamandla ehlukile.

• Ikhebula le-Coaxial:

  • Usekeloukudluliswa kwamandla(isib., ukunika amandla ama-amplifier ezinhlelweni ze-CATV).

Ukukhetha Nini?

• I-Fiber Optic:

  • Udinga izindawo ezinesivinini esikhulu kakhulu, ibanga elide, noma ezisindayo ze-EMI.

  • Amanethiwekhi okuvikela ikusasa (isib. amadolobha ahlakaniphile, i-IoT).

  • Izinhlelo zokusebenza ezidinga ukuphepha okuphezulu nokuthembeka.

• Ikhebula le-Coaxial:

  • Izilungiselelo ezingabizi kakhulu (isb., i-TV/i-inthanethi yekhebula lendlu).

  • Ukuqapha ividiyo okufushane (i-CCTV) noma izinhlelo zakudala.

  • Amanethiwekhi e-hybrid fiber-coaxial (HFC) (avame kakhulu kuma-ISP ekhebula).

Amathrendi Esikhathi Esizayo

• I-fiber opticUkwamukelwa kuyashesha kwe-5G, izinsizakalo zamafu, kanye nengqalasizinda ehlakaniphile.

• Izintambo ze-Coaxialkusalokhu kubalulekile kumanethiwekhi e-HFC kanye nezinhlelo ezindala kodwa kancane kancane kuyasuswa ngenxa ye-fiber.

Isiphetho:
Izintambo ze-fibre optic zisebenza kahle kakhulu ngesivinini, ibanga, kanye nokuthembeka, okwenza zibe zilungele izinhlelo zokusebenza zesimanje ezifunwa kakhulu. Izintambo ze-coaxial zingabizi kakhulu ezinhlelweni zebanga elifushane, ezindala, noma ezihlanganisiwe kodwa zilwa nemikhawulo ye-bandwidth kanye nokuphazamiseka. Ukukhetha kuncike kwisabelomali sakho, izidingo zobuchwepheshe, kanye nemigomo yokukhulisa.
