Ihinduka rya BOB rya tekinoroji ya HDV Phoelectron Technology LTD

1. Gahunda yo gutangiza BOB:

1. Gahunda yo gutangiza BOB ya tekinoroji ya HDV Phoelectron LTD:

Nukugirango dusuzume imbaraga za optique hamwe namakarita yikarita yo kuzimangana kumpera zihererekanyabubasha, kandi uyakira akeneye guhinduranya ibyiyumvo byayo no gukurikirana RSSI.

Igipimo cyo gutangiza BOB:

2. Igishushanyo cya BOB igishushanyo cya HDV Phoelectron Technology LTD.:

Igishushanyo mbonera cya BOB igishushanyo mbonera, ikizamini cyinzira imwe, guhuza ibintu bigoye hanze, attenuator, metero yamakosa, metero yimbaraga, CDR nibindi bikoresho bigomba kugurwa ukundi. Buri biro byakazi bisaba mudasobwa kugirango ishyigikire ikizamini.

1. Kumenyekanisha urukurikirane rwa ES-BOBT8 ibikoresho byo gupima BOB:
2. Irashobora gushyigikira imiyoboro igera kuri 8 yikizamini cya BOB, Imbere yimbaraga za metero imbere na attenuator, irashobora kurangiza kohereza no kwakira ikizamini hamwe nikizamini icyarimwe;
3. Imikorere ya BERT ihuriweho hamwe na 2xSFP + Imigaragarire yumucyo, irashobora gushyigikira 1.25G ~ 10G optique yerekana ibimenyetso, kugirango itange isoko yumucyo wibizamini bya BOB;
4. Integrated CDR Trigger out, imbere yonyine yubatswe yisaha yisaha, irashobora gutanga ikimenyetso cyisaha gikenewe mugupima igishushanyo mbonera cyamaso;
5. Imashini yonyine ya Calibration power irashobora gutanga optique ya optique ya Calibration detection.

ES-BOBT8 ikurikirana rya sisitemu ya BOB itanga urutonde rwuzuye rwibikoresho byikizamini, bishobora gutanga imiyoboro ntarengwa ya 8 yaONUIkizamini cya BOB. Ikizamini cya BER nisoko yumucyo, attenuator, metero yingufu, kugabana uburebure bwumurongo, optique ihinduranya nibindi bikoresho byinjijwe mubikoresho bimwe, hamwe na software ya BOB yumwuga wo gukoresha ibizamini, irashobora gutanga igisubizo cyuzuye cyibisubizo bya BOB.

2 、Ihame ryo gukora ibyuma:

Uruhare rwa ES-BOBT8 yuruhererekane rwibikoresho bya BOB:

1.Mu nzira yo kubyara, reba nibaONUoptique port luminous power nibisanzwe mugihe nyacyo
2.Reba niba imbaraga za optique zakiriwe zasomwe naONUicyambu cya optique nukuri.

Ihame ryakazi rya sisitemu yibikoresho:

1. Porogaramu yo hejuru ya mudasobwa muri sisitemu y'imikorere ihujwe na USB ya USB ya SCM U1 (moderi C8051F340) ikoresheje interineti ya USB muri sisitemu yo kwipimisha kugirango imenye imashini n'imashini;
2 bus.
3. Ikosa ryerekana biti chip VSC8228 yohereza ikimenyetso cyubwoko bwigipimo cyagenwe nigipimo ukurikije amabwiriza, kandi igatwara module ya OLT kugirango yohereze ibimenyetso bya optique yubwoko bwa code hamwe nigipimo binyuze muri interineti ya SerDES. Uburebure bwa OLT yoherejwe ni 1490nm, kandi urumuri rugabanyijemo umunani binyuze mu gucamo ibice. Nyuma yo kugenzura DAC igenzura VOA ihuza imbaraga zidasanzwe za optique, ihujwe naONUicyambu.ONUasoma imbaraga zijyanye na optique akayigereranya nagaciro nyako.
4 voltage yinjiza pin ya attenuator ya VOA, kugirango urumuri rutangwa na module ya PON OLT ruhujwe nimbaraga zabigenewe, hanyuma ugahuzwa nicyambu cya optique yaONU.
5. Uburyo bwa ADC bwo gushyira mubikorwa: Nyuma yumucyo utangwa naONUigaragazwa na PD (Photodetector), PD itanga ibimenyetso byerekana ibimenyetso byubunini butandukanye ukurikije imbaraga za signal optique, kandi bigahinduka mumashanyarazi hamwe numubare mugari kandi ugasobanuka neza binyuze muri logarithmic ihindura ADL5303. Agaciro kamenyekanye na AD5593 hanyuma gahindurwa mubimenyetso bya digitale binyuze muri bisi ya I2C unyuze muri SCM U1 (moderi C8051F340) hanyuma amaherezo yerekanwe kumurongo wa mudasobwa yakiriye.
