Ukuphonononga umahluko phakathi kwe-OU, i-ONT, i-SFU, kunye ne-hgu.

Xa kufikwa kwizixhobo zecala lomsebenzisi kwi-fiber ye-Broadband fiber, sihlala sibona amagama esinganjenge-onu, ont, sfu, kunye ne-hgu. Ithetha ntoni le gama? Yintoni umahluko?

1. I-Onus kunye ne-ovents

Iindidi zezicelo eziphambili zokufikelela kwi-fiber ye-Broadband Optical Fible ibandakanya: i-ftth, ftto, kunye ne-FTTB, kunye neefom zezixhobo zomsebenzisi zahlukile kwiindidi ezahlukeneyo zesicelo. Izixhobo ze-ftti zabasebenzisi kwaye i-ftto isetyenziswa ngumsebenzisi omnye, obizwa ngokuba yi-ont (i-ont yenethiwekhi yenethiwekhi), kunye ne-terttb yenethiwekhi ebizwa ngokuba ngabasebenzisi abaninzi, ebizwa ngokuba yi-Onu iyunithi yenethiwekhi).

Umsebenzisi okhankanywe apha ubhekisa kumsebenzisi ohlawulelwa ngokuzimeleyo ngumqhubi, hayi inani lezikhululo ezisetyenzisiweyo. Umzekelo, i-ont ye-ftth ikwabelwa i-terminals ezininzi ekhaya, kodwa kuphela umsebenzisi kuphela onokubalwa.

I-2. Iindidi zee-onts

I-ontYile nto siyibiza ngokuba yimodyuli eyahlukileyo, eyahlulahlulwe yaba yi-SFU (iyunithi yosapho olunye, iyunithi yomsebenzisi we-Gu (i-Hu (iYunithi yeNdawo yaseKhaya, iYunithi yaseKhaya) kunye neSbu (iyunithi yomsebenzisi weshishini).

2.1. Sfu

I-SFU ngokubanzi ine-1 ukuya kwi-4 i-Ethernet ye-ERERNet, i-2 ukuya kwiifowuni ezi-2, kwaye ezinye iimodeli zikwanemikhombeko ye-Cable. I-SFU ayinayo umsebenzi wamanzi ekhaya, kwaye kuphela itheminali exhunyiwe kwi-Ethernet Port Short ukuya kufikelela kwi-Intanethi, kwaye umsebenzi wokulawulwa okude ubuthathaka. Imodem ye-optical esetyenziswe kwinqanaba lokuqala le-ftth ye-sfu, ebinqabile ukusetyenziswa ngoku.

2.2. Hus

Imifanekiso ye-Optical Exinyelweyo exhotyiswe ngabasebenzisi be-ftth ivulwe kwiminyaka yakutshanje yonke i-HU. Xa kuthelekiswa ne-SFU, iHGE inezibonelelo zilandelayo:

(1) HU sisixhobo sesango, esilungele uthungelwano lwasekhaya; Ngelixa i-SFU sisixhobo sokuhambisa esibonakalayo, esingawanabo ubuchule beesango, kwaye ngokubanzi kufuna ukusebenzisana kwezixhobo zesango ezinjengeendlela zasekhaya kwinethiwekhi yasekhaya.

. Ngelixa udidi lwe-SFU luxhasa kuphela ungqimba-2 Imowudi yokuvala, elingana ne-windows-2 yokutshintsha.

. Ngelixa i-SFU kufuneka ityhilwe yikhompyuter yomsebenzisi okanye ifowuni ephathekayo okanye nge-router yasekhaya.

(4) HGU kulula ukwenzela umsebenzi omkhulu kunye nolawulo lolondolozo.

HGU zihlala ne-wifi kwaye ine-USB yezibuko.

2.3. Sbus

I-SBU isetyenziselwa ukufikelela kwi-ftto yomsebenzisi, kwaye ngokubanzi inomnxibelelanisi we-Ethernet, kwaye ezinye iimodeli zine-E1 i-intanethi, umnxibelelanisi we-Fifa, okanye umsebenzi we-wifi. Xa kuthelekiswa ne-SFU kunye ne-HU, uSbu inentsebenzo yokukhusela umbane kunye nokuzinza okuphezulu, kwaye ikwasetyenziswa kwizihlandlo zangaphandle ezinjengokuphathwa kwevidiyo.

3. Uhlobo lwe-Onu

I-OUT yahlulwe yaba yi-MD (indawo yokuhlala eninzi, iyunithi yemivuzo emininzi) kunye ne-MTU (iyunithi yemiqathango emininzi, iyunithi yemiqathango emininzi).

I-MUD isetyenziselwa ukufikelela kubasebenzisi bokuhlala abaninzi phantsi kohlobo lwesicelo se-FTTB, kwaye ngokubanzi inonxibelelwano ezinamacala ama-4 ubuncinci, zihlala zine-8, 16, i-fell (i-fets (i-fets (i-fets (i-fets (i-fell (i-fets (efowunini eqinileyo).

I-MTU isetyenziselwa ukufikelela kwabasebenzisi beshishini ezininzi okanye i-terminals ezininzi kwishishini elinye kwi-FTTB meko. Ukongeza kumnxibelelanisi we-Ethernet Ubume kunye nomsebenzi we-MTU zihlala zifana nezo ze-MU. Umahluko, kodwa ukusebenza kombane kungcono kwaye uzinzo luphezulu. Ngokukwenyani kwe-ftto, imeko yesicelo ye-MTU incinci kwaye incinci.

4. Isishwankathelo

I-Broadband yeFibber fiber yokufikelela ikakhulu i-PN Ceechnology. Xa uhlobo oluthile lwesixhobo somsebenzisi alwahlula-hlukeneyo, izixhobo zomsebenzisi zenkqubo ye-PN Ingabizwa ngokuba yi-Onu.

I-OTU, i-ONT, i-SFU, i-HU ... Zonke ezi zixhobo zichaza izixhobo ezisecaleni zabasebenzisi ezivela kwii-angles ezibanzi ezivela kwii-angles ezahlukeneyo, kwaye ubudlelwane phakathi kwabo buboniswe kumzobo ongezantsi.
