Pūwae Whakawhiti Whatu MMF 100GBASE-SR4 QSFP28 850nm 100m DOM MPO-12/UPC Hototahi Cisco, Wehenga ki te 4 x 25G-SR me te DDM
Whakaahuatanga
+ Kua hangaia te Cisco QSFP-100G-SR4-S Hototahi QSFP28 Optical Transceiver Module hei whakamahi i roto i te 100GBASE Ethernet tae atu ki te 100m i runga i te muka aratau maha OM4 (MMF) mā te whakamahi i te roanga ngaru o te 850nm mā te hononga MTP/MPO-12. E tutuki ana tēnei transceiver ki te paerewa IEEE 802.3bm 100GBASE-SR4 me CAUI-4. Kei te wātea hoki ngā mahi tātaritanga mamati mā te atanga I2C, e ai ki te QSFP28 MSA, kia taea ai te uru atu ki ngā tawhā whakahaere wā-tūturu. Mā ēnei āhuatanga, he ngāwari ki te tāuta, he pai hoki tēnei transceiver ka taea te whakawhiti wera hei whakamahi i roto i ngā tono maha, pērā i ngā pokapū raraunga, ngā whatunga rorohiko mahi-teitei, ngā tono matua hinonga me te paparanga tohatoha.

Whakaahuatanga Whānui
Kua hangaia te OP-QSFP28-01 hei whakamahi i roto i ngā hononga 100 Gigabit ia hekona i runga i te muka aratau maha.
E tutuki ana ēnei whakaritenga ki te QSFP28 MSA me te IEEE 802.3bm. Kei roto i te wāhanga tuku whatu o te tuku he huinga VCSEL (Poutū Āputa Mata Emitting Laser) 4-hongere, he arai tāuru 4-hongere me te taraiwa laser, ngā aroturuki tātaritanga, ngā poraka whakahaere me te poraka whakahāngai. Mō te whakahaere mōrahi, kei roto i te atanga whakahaere he atanga Raupapa Waea Rua o ngā tohu karaka me ngā raraunga. Ngā aroturuki tātaritanga mō
Ka whakatinanahia te pānga VCSEL, te pāmahana o te kōwae, te mana whatu kua tukuna, te mana whatu kua whiwhi me te ngaohiko tuku, ā, ka wātea ngā hua mā te atanga TWS. Ka whakatūria ngā paepae whakaoho me te whakatūpato mō ngā āhuatanga e aroturukitia ana. Ka whakatakotoria ngā haki, ā, ka puta ngā whakararuraru ina
kei waho o ngā paepae ngā āhuatanga. Ka whakatakotoria hoki ngā haki, ā, ka hangaia he aukati mō te ngaronga o te tohu whakauru
(LOS) me ngā āhuatanga hapa o te tuku. Kua herea ngā haki katoa, ā, ka noho tonu ahakoa kua whakakorea te āhuatanga e tīmata ana i te here, ā, ka tīmata anō te mahi. Ka taea te huna i ngā aukati katoa, ā, ka tautuhia anō ngā haki mā te pānui i te rēhita haki e tika ana. Ka pehia te putanga whatu mō te ngaronga o te tohu whakauru mēnā kāore e monoa te pehia. Mā te kimi hapa, te whakakorenga hongere rānei mā te atanga TWS ka whakakorea te hongere. Kei te wātea ngā mōhiohio mō te tūnga, te whakaoho/whakatūpato me te hapa mā te atanga TWS.
Kei roto i te wāhanga kaiwhiwhi whatu o te taputapu whakawhiti he huinga photodiode PIN 4-hongere, he huinga TIA 4-hongere, he arai putanga 4-hongere, he aroturuki tātaritanga, me ngā poraka whakahaere me te whakahāngai. Kua whakatinanahia ngā aroturuki tātaritanga mō te mana whakauru whatu, ā, kei te wātea ngā hua mā te atanga TWS. Kua whakatūria ngā paepae whakaoho me te whakatūpato mō ngā huanga e aroturukitia ana. Kua whakatakotoria ngā haki, ā, ka puta he aukati ina kei waho o ngā paepae ngā huanga. Kua whakatakotoria hoki ngā haki, ā, ka puta he aukati mō te ngaronga o te tohu whakauru whatu (LOS). Kua herea ngā haki katoa, ā, ka noho tonu te tautuhinga ahakoa kua mārama te āhua e tīmata ana te haki, ā, ka tīmata anō te mahi. Ka taea te huna i ngā aukati katoa, ā, ka tautuhia anō ngā haki i te pānui i te rēhita haki e tika ana. Ka pehi te putanga hiko mō te ngaronga o te tohu whakauru (ki te kore e monoa te pehi) me te whakakorenga o te hongere mā te atanga TWS. Kei te wātea ngā mōhiohio tūnga me te whakaoho/whakatūpato mā te atanga TWS.
