Tuhipoka:
- Ko te TX Fault he kaikohi tuwhera/whakaputa wai, me toia ki runga me te parenga 4.7K–10KΩ i runga i te papa manaaki.Toia ake ngaohiko i waenga i te 2.0V me te VccT, R+0.3V.I te teitei, ka tohu te putanga he hapa laser o etahi momo.Ko te iti e tohu ana i te mahi noa.I roto i te ahua iti, ka toia te putanga ki <0.8V.
- Ko te mono TX he whakaurunga ka whakamahia hei kati i te whakaputanga whatu tuku.Ka toia ki roto i te kōwae me te parenga 4.7–10 KΩ.Ko ona ahuatanga:
Iti (0 – 0.8V): Kaituku i runga
(>0.8, <2.0V): Kaore i tautuhia
Teitei (2.0 - 3.465V): Kua Mono te Kaituku
Tuwhera: Kua Mono te Kaituku
- Mod-Def 0,1,2.Koinei nga titi whakamaramatanga kōwae.Me toia ki runga me te parenga 4.7K – 10KΩ i runga i te papa manaaki.Ko te ngaohiko kume-ake kia VccT, VccR ranei.
Ko te Mod-Def 0 he mea whakatuu e te kōwae hei tohu kei reira te kōwae
Ko te Mod-Def 1 te raina karaka o te atanga rangatū waea e rua mo te ID rangatū
Ko te Mod-Def 2 te raina raraunga o te atanga rangatū waea e rua mo te ID rangatū
4. Ko te LOS (Loss of Signal) he kaikohi tuwhera/whakaputa wai, me toia ki runga me te parenga 4.7K – 10KΩ.Toia ake ngaohiko i waenga i te 2.0V me te VccT, R+0.3V.I te teitei, ka tohu tenei putanga ko te mana whatu kua riro kei raro iho i te tairongo kaiwhiwhi take kino rawa (i te mea kua tautuhia e te paerewa e whakamahia ana).Ko te iti e tohu ana i te mahi noa.I roto i te ahua iti, ka toia te putanga ki <0.8V.
- Ko VeeR me VeeT pea ka hono a roto i roto i te kōwae SFP.
- RD-/+: Ko enei nga putanga kaikawe rereke.Ko enei he DC honoa 100Ω raina rereke me whakamutu ki te 100Ω (rereke) i te kaiwhakamahi SERDES.
- Ko VccR me VccT te kaikawe me te tuku hiko hiko.Kua tautuhia hei 3.3V ± 5% i te titi tūhono SFP.Ko te 450mA te rahinga o naianei.E whakaatuhia ana i raro iho nei te tātari hiko a te poari kaihautu.Me whakamahi nga inductors me te parenga DC iti iho i te 1Ω kia mau tonu ai te ngaohiko e hiahiatia ana i te titi whakauru SFP me te ngaohiko tuku 3.3V.Ina whakamahia te whatunga tātari tuku, ko te whakauru wera o te kōwae whakawhiti SFP ka puta te ohu o te ia kaua e neke ake i te 30 mA nui ake i te uara o te noho pumau.Ko te VccR me te VccT ka hono-a-roto i roto i te kōwae whakawhiti SFP.
- TD-/+: Ko enei nga whakaurunga whakawhiti rereke.He AC-honoa, he raina rereke me te 100Ω te whakamutu rereke i roto i te kōwae.Ko te hononga AC ka mahia i roto i te waahanga, na reira kaore e hiahiatia i runga i te papa manaaki.

Nga tono hua
GEPON OLT Mo te Tono P2MP
Whānui
Ko te HDV ZL5432099-ICS transceiver me te tautoko i te reeti raraunga o te 1.25 Gbps angamaheni mo te tono GEPON OLT ki te 20km te tawhiti o te whakawhiti, kua hangaia he hui ki te China Telecom EPON taputapu hangarau whakaritenga V2.1 1000BASE-PX20 + whakaritenga.Ko te reecptacle SC mo te atanga whatu.
Ko te kōwae e whakarato ana i nga korero tātaritanga mamati mo ona ahuatanga whakahaere me tona mana, tae atu ki te tuku hiko, te piunga taiaho, te mana whatu urunga kaiwhiwhi, te pāmahana kōwae, me te ngaohiko tuku.Ko nga raraunga whakatikatika me te whakaoho / whakatupato i te paepae ka tuhia, ka rongoa ki te mahara o roto (EEPROM).He hototahi te mapi mahara ki te SFF-8472, e whakaatuhia ana i te Whakaahua 2. Ko nga raraunga tātaritanga he uara A/D mata, me tahuri ki nga waeine o te ao ma te whakamahi i nga taurite whakatikatika kua rongoa ki nga waahi EEPROM 56 - 95 i te A2h.
