Ndemanga:
- TX Fault ndi chotulutsa chotseguka / chotsitsa, chomwe chiyenera kukokedwa ndi 4.7K-10KΩ resistor pa bolodi la alendo. Kokani voteji pakati pa 2.0V ndi VccT, R+0.3V. Zikakwera, zotulutsa zikuwonetsa vuto la laser lamtundu wina. Low limasonyeza ntchito yachibadwa. Pamalo otsika, zotulutsa zidzakokedwa ku <0.8V.
- TX disable ndi cholowetsa chomwe chimagwiritsidwa ntchito kutseka ma transmitter optical output. Imakokedwa mkati mwa gawoli ndi 4.7-10 KΩ resistor. Makhalidwe ake ndi awa:
Pansi (0 - 0.8V): Transmitter on
(> 0.8, <2.0V): Zosadziwika
Pamwamba (2.0 - 3.465V): Transmitter Wolemala
Tsegulani: Transmitter Yayimitsidwa
- Mod-Def 0,1,2. Izi ndi zizindikiro za ma module. Ayenera kukokedwa ndi 4.7K - 10KΩ resistor pa board host. Mphamvu yamagetsi iyenera kukhala VccT kapena VccR.
Mod-Def 0 imakhazikitsidwa ndi gawo kusonyeza kuti gawoli lilipo
Mod-Def 1 ndiye mzere wa wotchi wa mawonekedwe awiri a waya wa serial ID
Mod-Def 2 ndi mzere wa data wa mawonekedwe awiri a waya wa serial ID
4. LOS (Kutayika kwa Chizindikiro) ndizotsegula zosonkhanitsa / kukhetsa, zomwe ziyenera kukokedwa ndi 4.7K - 10KΩ resistor. Kokani voteji pakati pa 2.0V ndi VccT, R+0.3V. Zikakhala zazitali, kutulutsa uku kukuwonetsa kuti mphamvu yolandila yolandila ili pansi pazovuta zolandila (monga momwe zimafotokozedwera mulingo womwe ukugwiritsidwa ntchito). Low limasonyeza ntchito yachibadwa. Pamalo otsika, zotulutsa zidzakokedwa ku <0.8V.
- VeeR ndi VeeT zitha kulumikizidwa mkati mkati mwa gawo la SFP.
- RD-/+: Izi ndi zotulutsa zolandilira. Ndi mizere yosiyana ya 100Ω ya DC yomwe iyenera kuthetsedwa ndi 100Ω (zosiyana) kwa wogwiritsa SERDES.
- VccR ndi VccT ndi olandila ndi ma transmitter magetsi. Amatanthauzidwa ngati 3.3V ± 5% pa pini yolumikizira SFP. Kuchuluka kwaposachedwa ndi 450mA. Analimbikitsa gulu khamu mphamvu zosefera magetsi zikuwonetsedwa pansipa. Ma inductors okhala ndi DC kukana osakwana 1Ω ayenera kugwiritsidwa ntchito kuti asunge magetsi ofunikira pa pini yolowetsa ya SFP yokhala ndi 3.3V voliyumu yamagetsi. Mukamagwiritsa ntchito makina opangira zosefera, kuwotcha kwa module ya transceiver ya SFP kumapangitsa kuti pakhale mphamvu yosapitilira 30 mA kuposa mtengo wokhazikika. VccR ndi VccT zitha kulumikizidwa mkati mkati mwa gawo la transceiver la SFP.
- TD-/+: Awa ndi ma transmitter osiyanasiyana. Iwo ndi AC-ophatikizana, mizere yosiyana ndi 100Ω kusiyana pakati pa gawo. Kuphatikizika kwa AC kumachitika mkati mwa gawoli ndipo sikofunikira pa bolodi la alendo.

General
Transceiver ya HDV ZL5432099-ICS yomwe imathandizira kuchuluka kwa data ya 1.25 Gbps pakugwiritsa ntchito kwa GEPON OLT mpaka mtunda wa 20km, idapangidwa kuti ikumane ndi zofunikira zaukadaulo za China Telecom EPON V2.1 1000BASE-PX20+. SC rececptacle ndi mawonekedwe a kuwala.
Gawoli limapereka chidziwitso cha digito cha momwe amagwirira ntchito komanso momwe amagwirira ntchito, kuphatikiza mphamvu zotumizira, kukondera kwa laser, mphamvu yamagetsi yolandila, kutentha kwa module, ndi magetsi operekera. Kuwongolera ndi alamu / chenjezo lazomwe zimalembedwa ndikusungidwa mu kukumbukira mkati (EEPROM). Mapu a kukumbukira amagwirizana ndi SFF-8472, monga momwe tawonetsera mkuyu. 2.
