Gushakisha itandukaniro muri Onu, ONT, SFU, na HGU.

Iyo bigeze kubikoresho byumukoresha muri Broadband fibre, akenshi tubona amagambo yicyongereza nka Onu, ONT, SFU, na HGU. Aya magambo asobanura iki? Ni irihe tandukaniro?

1. Onus na Onts

Ubwoko bwibanze bwa porogaramu yo mugari ya optique ya fibre ya fibre harimo: ftth, ftto, na ftb, kandi uburyo bwo kubakoresha ibikoresho bitandukanye muburyo butandukanye. Abakoresha-kuruhande rwibikoresho bya ftth na ftto bikoreshwa numukoresha umwe, bita Optique Network, hamwe nibikoresho bya Optique byasangiwe nabakoresha benshi, bitwa Optique Igice cya Optique, Optical Igice cya Network).

Umukoresha wavuzwe hano bivuga umukoresha wishyuwe yigenga numukoresha, ntabwo umubare wa terminal yakoreshejwe. Kurugero, ont ya ftti muri rusange isangirwa na terefone nyinshi murugo, ariko umukoresha umwe gusa arashobora kubarwa.

2. Ubwoko bwa onts

ONTnicyo dusanzwe twita modem optique, igabanijwemo sfu (igice cyumuryango umwe, ishami ryumuryango umwe), ishami rya Gateway, ishami rya Gateway, Igice cyubucuruzi, igice cyabakoresha ubucuruzi).

2.1. Sfu

SFU muri rusange ifite interineti 1 kugeza kuri 4 ya Ethernet, 1 kugeza kuri 2 ikora terefone ihamye, kandi moderi zimwe zifite na televiziyo ya televiziyo. SFU ntabwo ifite imikorere yimbere, kandi terminal gusa ihujwe nicyambu cya Ethernet gishobora guhamagara kugirango ugere kuri enterineti, kandi imikorere yo gucunga kure irakomeye. Modem Optique ikoreshwa mu cyiciro cya mbere cya ftth ni iy SFU, ni gake ikoreshwa ubu.

2.2. HGUS

Modem ya Optique ifite abakoresha ba ftth yafunguye mumyaka yashize bose ni HGU. Ugereranije na SFU, HGU ifite ibyiza bikurikira:

(1) HGU ni igikoresho cyamare, cyoroshye kumiyoboro yo murugo; Mugihe SFU nigikoresho gitwara gicuruza, kidafite ubushobozi bwamare, kandi muri rusange gisaba ubufatanye bwibikoresho bya remice nka router murugo.

. Mugihe wa SFU gusa ushyigikira gusa umwanya-2 ushushanya, uhwanye na lateer-2.

. Mugihe SFU igomba guhamagarwa na mudasobwa yumukoresha cyangwa terefone igendanwa cyangwa unyuze murugo.

(4) HGU yoroshye kubikorwa byinshi byo gukora no gucunga neza.

HGU mubisanzwe izana na wifi kandi ifite icyambu cya USB.

2.3. Sbus

Shu ikoreshwa cyane kubakoresha FTTO, kandi muri rusange ifite interineti ya Ethernet, kandi moderi zimwe zifite e1, umurongo wa interineti, umurongo wa telefoneline, cyangwa imikorere ya WiFi. Ugereranije na SFU na HGU, SBU ifite neza imikorere yo kurinda amashanyarazi no gushikama cyane, kandi nanone bikunze gukoreshwa mu bihe byo hanze nka videwo.

3. Ubwoko bwa Onu

Onu igabanijwemo igice cya MDU (Utunganiye-homen, ishami rishinzwe kubaturage ryinshi) na MTU (ishami rinini, ishami rinini, igice kinini).

MDU ikoreshwa cyane cyane kubijyanye nabakoresha benshi batuye mubwoko bwa FTTB, kandi muri rusange ifite byibuze 4 ukoresha, ubusanzwe hamwe na 8, 16, 24 fer cyangwa fe + kuri terefone (terefone ihamye).

Mtu akoreshwa cyane cyane kugirango abone uburyo bwinshi bwabakoresha imishinga cyangwa terminal nyinshi muri ikigo kimwe muri Scenario ya FTTB. Usibye Ethernet Interface na interineti ikosowe, irashobora kandi kugira E1 interineti; Imiterere n'imikorere ya Mtu mubisanzwe ntabwo ari kimwe na MDU. Itandukaniro, ariko imikorere yo kurengera amashanyarazi nibyiza kandi gushikama ni hejuru. Hamwe na Phulisation ya Ftto, ibintu bya porogaramu bya MTU biragenda bikura bito kandi bito.

4. Incamake

Broadband Optical Fibre Kwinjira Byinshi Kwanga Tekinoroji ya Pon. Iyo uburyo bwihariye bwibikoresho byumukoresha bidafite ishingiro, ibikoresho byumukoresha bya sisitemu ya Pon birashobora guhuzwa bivugwa nka onu.

Ou, ONT, SFU, HGU ... Ibi bikoresho byose bisobanura ibikoresho byumukoresha kugirango ubone ibicuruzwa bya Broadband biva mu mpande zitandukanye, kandi umubano hagati yabo werekanwa mumashusho hepfo.
