I le taimi nei, faʻatasi ai ma le atinaʻeina o fesoʻotaʻiga faʻamatalaga tekonolosi, ua sili atu ona matou faʻaogaina tomai faʻapitoa, o se tasi o le faʻaaogaina opdh transceivers opitika. Talu ai ua matou faʻaaogaina pdh optical transceivers, o le tuʻuina atu o faʻamatalaga ua matua talepeina ai le le atoatoa o faʻamatalaga masani.

1. Fa'atomuaga pu'upu'u o meafaigaluega fa'a-transceiver opitika PDH

PDH feso'ota'iga feso'ota'iga transceiver fa'aaogaina le tele-tele feso'ota'iga feso'ota'iga ma aia tatau fa'ale-mafaufau tuto'atasi, fa'aogaina o le taimi fa'atekonolosi multiplexing, numera numera loka ma le uati fa'atekonolosi, ma le fa'alavelave fa'alavelave 2M tekinolosi fa'afeso'ota'i, lea e fetaui lelei mo taimi e maualuga le fa'atuatuaina mana'oga ma atoatoa. galuega fesoasoani. E pei o: China Mobile, China Unicom, fesoʻotaʻiga, eletise eletise, saogalemu lautele, militeri, auala tetele, vaalele ma isi fesoʻotaʻiga fesoʻotaʻiga tuuto. O le vaega o meafaigaluega e faʻaaogaina se FPGA lapopoa, lea e tuʻufaʻatasia ai le encoding, decoding, faʻaofiina o faʻamatalaga, ma le faʻailo faʻamalo, lea e faigofie ai le matagaluega ma faʻaleleia le faʻamaoni o le masini atoa.

O le PDH opitika transceiver faʻafefiloi ma faʻapipiʻi le faailo E1 ma tuʻuina atu i luga o se pea o alava mata. O le PDH optical transceiver network management function e faafaigofieina ai le pulega autasi o mea tau fesoʻotaʻiga e tagata faʻaoga pisinisi. E ala i le pulega o fesoʻotaʻiga tutotonu, e mafai ona faʻamaeʻaina galuega tau pulega e pei o le mataʻituina, faʻatulagaina, toe faʻaleleia, ma le faʻaleleia o galuega o meafaigaluega mamao.

2. Galuega autu ma foliga o le PDH optical transceiver

Tuuina atu le RS232 fesoʻotaʻiga pulega faʻafesoʻotaʻi, lagolago pulega faʻatasi fesoʻotaʻiga; (faatatau i le ave-grade NT-240D / 240D +) sapalai mana lua, faaleoleo vevela soofaatasi, (faatatau i le ave-vaega NT-240D / 240D +) tuuina atu 4 E1 tau pisinisi, uati numera atoa Toe faaleleia ma lamolemole vaega loka tekinolosi e mafai ona filifili AC220V , DC48V, DC + 24V, DC-24V sapalai eletise e tuʻuina atu ai le mataʻituina o faʻailo faʻalotoifale / tupulaga, O le moli lanu e tolu e faʻaalia e lagolagoina i le lotoifale / mamao E1 lala loopback, maua se tasi telefoni aloaia, maua se auala manino RS232 faamatalaga, ma le fua faatatau e 300-19.2Kbit / s adaptive.

3. PDH opitika transceiver galuega

a. E1 felauaiga: E mafai e le oloa ona iloa le 4-16 E1 (2Mb / s) faʻasalalauga fiber opitika.

b.Ethernet transmission: e ala i le filifiliga Ethernet module, e fa auala o le 10M / 100M adaptive Ethernet auaunaga e mafai ona iloa.

c.Service galuega: O le oloa e mafai ona faʻapipiʻiina i le telefoni feaveaʻi galuega e iloa ai le fesoʻotaʻiga pisinisi i le va o transceivers opitika e lua.

d.RS232 fa'amaumauga: O le oloa e maua ai le RS232 asynchronous data channel. O le fua faatatau o faʻamatalaga e faʻafetaui e le tagata lava ia i lalo ole 115.2Kb/s, ma o le faʻasologa o faʻamaumauga e faʻafetaui e le tagata lava ia.

f.Switch quantity interface: O le oloa e mafai ona faʻapipiʻiina i se fesoʻotaʻiga fesoʻotaʻiga faʻaogaina o le aofaʻi, lea e mafai ona faʻaogaina mo le faʻailo poʻo le pulea.
