Parizvino, nekuvandudzwa kwetiweki ruzivo tekinoroji, isu tine hunyanzvi hwekuita zvehunyanzvi hwekushandisa, imwe yacho kushandiswa kwepdh optical transceivers. Sezvo takashandisa pdh optical transceivers, kufambiswa kweruzivo kwakaputsa zvakanyanya kukanganisa kwechinyakare kufambisa mashoko.

1. Muchidimbu sumo yePDH optical transceiver michina

PDH network optical transceiver inotora maseketi makuru akabatanidzwa ane kodzero dzakazvimirira dzepfuma, kushandisa tekinoroji yekukamuranisa tekinoroji, kiyi yedhijitari yekukiya uye tekinoroji yekubvisa wachi, uye anti-interference 2M interface tekinoroji, iyo inonyanya kukodzera kune zviitiko zvine kuvimbika kwakanyanya zvinodiwa uye zvakakwana. mabasa ebetsero. Zvakadai se: China Mobile, China Unicom, nharembozha, simba remagetsi, chengetedzo yeruzhinji, mauto, migwagwa mikuru, yendege uye mamwe akazvipira kutaurirana network. Chikamu chehardware chinotora FPGA yakakura, iyo inobatanidza encoding, decoding, kuisa ruzivo, uye alarm switching, iyo inoita kuti dunhu rive nyore uye rinovandudza kuvimbika kwemuchina wese.

Iyo PDH optical transceiver inosanganisa uye inokodha chiratidzo cheE1 uye ichichitumira pane maviri optical fibers. Iyo PDH optical transceiver network manejimendi basa inofambisa iyo yakabatana manejimendi yekukurukurirana michina nevashandisi veindasitiri. Kuburikidza neiyo yepakati network manejimendi, manejimendi mabasa akadai sekutarisa, kumisikidza, kuseta zvakare, uye kusimudzira basa kweiyo inoenderana kure kure michina inogona kupedzwa.

2. Mabasa makuru uye maitiro ePDH optical transceiver

Ipa RS232 network manejimendi manejimendi, tsigira yakabatana network manejimendi; (inoshanda kune inotakura-giredhi NT-240D/240D+) magetsi maviri, mutual inopisa backup, (inoshanda kune inotakura-giredhi NT-240D/240D+) inopa 4 E1 bhizinesi zviteshi, yakazara dijitari wachi Kudzoreredza uye yakatsetseka chikamu chekiyi tekinoroji inogona kusarudza AC220V , DC48V, DC+24V, DC-24V magetsi ekupa yakakwana yemunharaunda/peer end alarm monitoring, Chiedza chemavara matatu chinoratidza kuti chinotsigira nharaunda / kure E1 bazi loopback, inopa imwe nhare yepamutemo, inopa yakajeka RS232 data chiteshi, uye chiyero chiri 300-19.2Kbit / s adaptive.

3. PDH optical transceiver basa

a. E1 kutapurirana: Chigadzirwa chinogona kuona 4-16 E1 (2Mb/s) optical fiber kutapurirana.

b.Ethernet kutapurirana: kuburikidza neinosarudzika Ethernet module, nzira ina dze10M/100M adaptive Ethernet sevhisi optical fiber transmission inogona kuitika.

c.Service basa: Chigadzirwa chacho chinogona kunge chakashongedzerwa nebasa refoni yebasa kuti uone kutaurirana kwebhizinesi pakati peaviri optical transceivers.

d.RS232 data: Chigadzirwa chinopa RS232 asynchronous data channel. Nhamba yedata inozvigadzirisa yega pazasi 115.2Kb/s, uye iyo data fomati inozvigadzirisa yega.

f.Switch quantity interface: Chigadzirwa chacho chinogona kugadzirirwa ne relay output switch quantity interface, iyo inogona kushandiswa kune alarm kana kutonga.
