    2. Hoahoa hononga BOB o HDV Phoelectron Technology LTD.:

    Ko te hoahoa hononga whakamatautau BOB tikanga, te whakamatautau kotahi-ara, te hononga o waho matatini, te attenuator, te mita hapa, te mita hiko, te CDR me etahi atu taputapu me hoko motuhake. Me whai rorohiko ia teihana mahi hei tautoko i te whakamatautau.

    1. Te whakaurunga o nga taputapu whakamatautau BOB raupapa ES-BOBT8:
    2. Ka taea te tautoko ki nga waahana 8 mo te whakamatautau BOB, Te mita hiko whakauru o roto me te attenuator, ka taea te whakaoti i te tuku me te tango i te patuiro me te whakamatautau i te wa ano;
    3. Ko te mahi BERT whakauru me te 2xSFP + atanga puna marama, ka taea te tautoko i te 1.25G ~ 10G putanga tohu tohu, ki te whakarato i te puna marama tohu mo te whakamatautau BOB sensitivity;
    4. Whakakotahitia te CDR Trigger ki waho, te whakaora i te tohu karaka a-roto, ka taea te whakarato i te tohu karaka e hiahiatia ana mo te whakamatautau hoahoa kanohi whatu;
    5. Ka taea e te mita o te hiko te whakarite i a koe ake te whakarato i te kitenga whakaraeraetanga mana whatu.

    Ko te punaha whakamatautau BOB raupapa ES-BOBT8 e whakarato ana i te huinga katoa o nga otinga taputapu whakamatautau, ka taea te whakarato i te nuinga o nga waahana 8 oONUKo te whakamatautau BOB. Ko te kaiwhakaatu BER me te puna marama, te attenuator, te mita hiko, te wehenga o te roangaru, te whakawhiti matapihi me etahi atu taputapu kua whakauruhia ki roto i te taputapu kotahi, me te rorohiko rorohiko whakamatautau BOB ngaio, ka taea te whakarato i te huinga katoa o nga otinga whakamatautau BOB.

    2,Tikanga mahi taputapu:

    Te mahi a te raupapa ES-BOBT8 o nga punaha taputapu BOB:

    1.In the production process, check if theONUtauranga whatu mana luminous he noa i roto i te wā tūturu
    2.Tirohia mehemea kua panuitia te uara mana whatu e teONUhe tika te tauranga whatu.

    Tikanga mahi o te punaha taputapu:

    1. Ko te rorohiko rorohiko o runga i roto i te punaha whakahaere e hono ana ki te atanga USB o te SCM U1 (tauira C8051F340) na roto i te atanga USB i roto i te punaha whakamatautau ki te mohio ki te hononga tangata-miihini;
    2. Ko te SCM U1 (tauira C8051F340) e whakahaere ana i te U3 (bit detector error chip VSC8228, signal generator), OLT module (PON SFP), ADC (i whakatinanahia e ADL5303 me AD5593), me DAC (i whakatinanahia e MAX4230 me AD5593) na roto i te IIC pahi.
    3. Ka tukuna e te maramara moka hapa VSC8228 te tohu o te momo waehere kua tohua me te reiti e ai ki te tohutohu, ka peia te OLT ki te tuku i te tohu whatu o te momo waehere me te reiti ma te atanga SerDES. Ko te roangaru o te OLT i tukuna ko 1490nm, ka wehea te marama ki te waru ma te wehenga. I muri i te mana DAC attenuator VOA attenuates ki te mana whatu i tohua, kua hono ki teONUtauranga whatu.ONUka panui i te mana whatu e rite ana me te whakataurite ki te uara tuturu.
    4. Tikanga whakatinana DAC: Ka tukuna e te SCM U1 (tauira C8051F340) nga raraunga DAC ki AD5593 na roto i te pahi I2C, he tauranga I/O o AD5593 te whakaputa tohu hiko, ka puta he tohu ngaohiko na roto i te whakakaha whakahaere MAX4230, ka whakamahia ki te titi whakaurunga ngaohiko o te attenuator VOA, na te rama e tukuna ana e te PON OLT module ka whakahekehia ki te mana whatu kua tohua, ka hono atu ki te tauranga whatu o teONU.
    5. ADC tikanga whakatinanatanga: I muri i te marama i tukuna e teONUka kitea e te PD (photodetector), ka whakaputahia e te PD nga awa tohu o nga rahi rereke e ai ki te kaha o te tohu whatu, ka huri ki te ngaohiko me te awhe tau whanui me te tika teitei ake na roto i te kaitahuri logarithmic ADL5303. Ko te uara ka mohiotia e AD5593 ka huri hei tohu matihiko ma te pahi I2C ma te SCM U1 (tauira C8051F340) ka mutu ka whakaatuhia ki te atanga rorohiko manaaki.
