Iintambo ze-fiber optic kunye ne-coaxial zombini zisetyenziselwa ukudlulisa idatha, kodwa zahluke kakhulu kuyilo, ukusebenza, kunye nokusetyenziswa. Nantsi intelekelelo eneenkcukacha:

1. Indlela yokudlulisa

• I-Fiber Optic:

  • Ukusetyenziswaiipulses zokukhanya(iilaser/ii-LED) ezidluliselwa ngeefayibha zeglasi/zeplastiki.

  • Idatha ihamba ngeukubonakaliswa kwangaphakathi okupheleleyoembindini.

  • Iqulathe umqhubi ophakathi, isivikelo se-dielectric, ikhaka lesinyithi, kunye nejakethi yeplastiki yangaphandle.

2. Isantya kunye neBandwidth

• I-Fiber Optic:

  • Isantya: Ixhomekeke kuii-terabits ngomzuzwana (ii-Tbps)kuphando; ixhasa ngokwezorhwebo i-100+ Gbps.

  • Ibhendiwidth: Phantse ayinamda ngenxa yefrikhwensi ephezulu yokukhanya.

• Intambo yeCoaxial:

  • Isantya: Ngokwesiqhelo ukuya kuthi ga10 Gbps(umz., i-DOCSIS 4.0 ye-intanethi yekhebula).

  • Ibhendiwidth: Incitshiswe kukunciphisa isignali kwiifrikhwensi eziphezulu (ukuya kuthi ga kwi-1 GHz kwi-coax yanamhlanje).

3. Umgama kunye nokulahleka kweSignali

• I-Fiber Optic:

  • Umgama: Ifayibha yemowudi enye (i-SMF) inokudlulisaIikhilomitha ezingama-70–100+ngaphandle kwezinto eziphindaphindayo.

  • Ukunciphisa: Iphantsi kakhulu (~0.2 dB/km).

• Intambo yeCoaxial:

  • Umgama: Kulinganiselwe kwi~500 yeemitha(kwi-RG-6 esemgangathweni ophezulu) ngaphambi kokuba isignali yonakale.

  • Ukunciphisa: Ilahleko enkulu xa umgama usiya, ingakumbi xa udlula rhoqo.

4. Ukuphazamisa kunye nokuthembeka

• I-Fiber Optic:

  • Ukuzikhusela kwiukuphazamiseka kwe-electromagnetic (EMI)kunye nokuphazamiseka kwerediyo (RFI).

  • Akukho kungqubana okanye ukuvuza kwesiginali.

• Intambo yeCoaxial:

  • Uyilo olukhuselweyo luyanciphisa i-EMI/RFI kodwa alusebenziayinakukhuseleka(umz., ukuphazamiseka kweentambo zombane).

  • Ichaphazeleka "kukungena" (ingxolo engena kwintambo) kunye "nokuphuma" (ukuvuza kwesignali).

5. Ukhuseleko

• I-Fiber Optic:

  • Kunzima kakhulu ukucofa ngaphandle kokubonwa (ukuphazamiseka kokukhanya kuyabonakala).

  • Ilungele ukudluliselwa kwedatha ngokukhuselekileyo (umz., urhulumente, ezezimali).

• Intambo yeCoaxial:

  • Isesichengeni sokumamela ngokuvuza kwe-electromagnetic okanye iimpompo ezibonakalayo.

  • Ifuna ukubethela (umz., i-AES) kwidatha eyimfihlo.

6. Ixabiso

• I-Fiber Optic:

  • Iindleko eziphezulu kwangaphambili(ufakelo, ii-transceivers, izixhobo zokuqhawula).

  • Iindleko eziphantsi zexesha elide (ulondolozo oluncinci, olungenakulungiswa kwixesha elizayo).

• Intambo yeCoaxial:

  • Ufakelo olungabizi kakhulu(zifumaneka ngokubanzi, izihlanganisi ezilula ezifana nohlobo lwe-F).

  • Ukugcinwa okuphezulu ngokuhamba kwexesha (ukonakala kwesignali, ukulungiswa kwezixhobo zokukhusela).

7. Ukuqina kunye nobukhulu

• I-Fiber Optic:

  • Ingaphakathi leglasi ebuthathaka(ifuna ukuphathwa ngononophelo ngexesha lokufakwa).

  • Ibhityile, ilula, kwaye iguquguquka (ilungele imijelo exineneyo).

• Intambo yeCoaxial:

  • Kaninziukomelela ngokomzimbakodwa likhulu kwaye linzima.

  • Inokugqwala xa ijakethi yangaphandle yonakele.

8. Izicelo

• I-Fiber Optic:

  • Unxibelelwano olukude (ii-ISP backbones, iintambo eziphantsi kolwandle).

  • I-intanethi ekhawulezayo (FTTH), amaziko edatha, iinethiwekhi ze-5G.

  • Iinkqubo zemifanekiso yezonyango, ezomkhosi, nezemizi-mveliso.

• Intambo yeCoaxial:

  • I-Cable TV (CATV) kunye ne-intanethi ye-broadband (umz., i-DOCSIS).

  • Ukujonga ividiyo umgama omfutshane (CCTV).

  • Uthungelwano lwexesha elidlulileyo (i-Ethernet phezu kwe-coax) kunye nee-antenna zerediyo.

9. Ukulibaziseka

• I-Fiber Optic:

  • Ubambezelo olusezantsi(kufutshane nothumelo lwesantya sokukhanya).

  • Kubalulekile kwizicelo zexesha langempela (ukudlala imidlalo, urhwebo lwezabelo).

• Intambo yeCoaxial:

  • Ukulibaziseka okuphezulu ngenxa yokulibaziseka kokusasazwa kwesignali yombane.

10. Ukudluliselwa kwamandla

• I-Fiber Optic:

  • Ayikwazi ukudlulisa amandla ombane; izixhobo zifuna imithombo yamandla eyahlukileyo.

• Intambo yeCoaxial:

  • Inkxasouthumelo lwamandla(umz., ukunika amandla ii-amplifier kwiinkqubo ze-CATV).

Ukukhetha nini ukuba yeyiphi?

• I-Fiber Optic:

  • Kufuneka ube neendawo ezinesantya esiphezulu kakhulu, ezikude, okanye ezixineneyo kakhulu.

  • Iinethiwekhi ezikhusela ikamva (umz., izixeko ezikrelekrele, i-IoT).

  • Izicelo ezifuna ukhuseleko oluphezulu kunye nokuthembeka.

• Intambo yeCoaxial:

  • Useto olungabizi kakhulu (umz., iTV/i-intanethi yekhebula yasekhaya).

  • Iinkqubo zokujonga ividiyo ezimfutshane (i-CCTV) okanye iinkqubo zakudala.

  • Iinethiwekhi ze-hybrid fiber-coaxial (HFC) (ezixhaphakileyo kwii-ISP zekhebula).

Iindlela Zekamva

• I-fiber opticUkwamkelwa kwe-5G kuyakhawuleza, iinkonzo zelifu, kunye neziseko ezikrelekrele.

• Iintambo zeCoaxialzihlala zibalulekile kwiinethiwekhi ze-HFC kunye neenkqubo zakudala kodwa ziyancitshiswa kancinci kancinci ngenxa yefayibha.

Isiphelo:
Iintambo ze-fiber optic zibalasele ngesantya, umgama, kunye nokuthembeka, nto leyo eyenza ukuba zilungele ukusetyenziswa kwezixhobo zanamhlanje ezifunwa kakhulu. Iintambo ze-coaxial zibiza kancinci kwiinkqubo ezimfutshane, ezindala, okanye ezixutyiweyo kodwa ziyasokola ngenxa yemida ye-bandwidth kunye nokuphazamiseka. Ukhetho luxhomekeke kuhlahlo lwabiwo-mali lwakho, iimfuno zobugcisa, kunye neenjongo zokukhula.
