A halin yanzu, tare da haɓaka fasahar sadarwa ta hanyar sadarwa, muna da ƙarin ƙwarewar aikace-aikacen fasaha, ɗaya daga cikinsu shine amfani da supdh optical transceivers. Tun da mun yi amfani da pdh na gani transceivers, watsa bayanai ya karya kasawa na watsa bayanan gargajiya.

1. Taƙaitaccen gabatarwar kayan aikin transceiver na gani na PDH

PDH cibiyar sadarwa na gani transceiver rungumi dabi'ar manyan-sikelin hadedde da'irori tare da masu zaman kansu haƙƙoƙin mallaka ilimi, da ake ji lokaci rabo fasahar multixing, dijital lokaci kulle da agogon hakar fasahar, da anti-tsangwama 2M dubawa fasahar, wanda shi ne musamman dace da lokatai tare da high aminci bukatun da kuma cikakken. ayyuka na taimako. Kamar su: China Mobile, China Unicom, sadarwa, wutar lantarki, tsaro na jama'a, soja, manyan hanyoyi, jiragen sama da sauran hanyoyin sadarwa da aka sadaukar. Sashin kayan masarufi yana ɗaukar FPGA mai girma, wanda ke haɗa ɓoyayyiya, yanke hukunci, shigar da bayanai, da sauyawar ƙararrawa, wanda ke sa kewayawa mai sauƙi kuma yana haɓaka amincin injin gabaɗaya.

Mai ɗaukar gani na PDH yana haɗawa da ɓoye siginar E1 kuma yana watsa shi akan filaye biyu na gani. Ayyukan gudanarwa na cibiyar sadarwa na transceiver na PDH yana sauƙaƙe gudanar da haɗin gwiwar kayan aikin sadarwa ta masu amfani da masana'antu. Ta hanyar gudanarwar cibiyar sadarwa ta tsakiya, ana iya kammala ayyukan gudanarwa kamar saka idanu, daidaitawa, sake saiti, da haɓaka aiki na kayan aikin nesa masu dacewa.

2. Babban ayyuka da fasali na PDH na gani transceiver

Samar da RS232 cibiyar sadarwa na cibiyar sadarwa, goyan bayan haɗin gwiwar gudanarwar cibiyar sadarwa; (wanda ya dace da NT-240D / 240D + mai ɗaukar nauyi) mai samar da wutar lantarki mai dual, madadin zafi na juna, (wanda ya dace da NT-240D / 240D + mai ɗaukar nauyi) yana ba da tashar jiragen ruwa na E1 na 4, cikakken agogon dijital farfadowa da santsi na fasahar kulle lokaci na iya zaɓar AC220V , DC48V, DC + 24V, DC-24V samar da wutar lantarki don samar da cikakken gida / takwarorinsu karshen saka idanu, The Hasken launi uku yana nuna cewa yana goyan bayan reshe na gida / m E1 loopback, yana ba da tarho na hukuma ɗaya, yana ba da tashar bayanan RS232 na gaskiya, kuma ƙimar shine 300-19.2Kbit/s daidaitacce.

3. PDH aikin transceiver na gani

a. E1 watsa: Samfurin iya gane 4-16 E1 (2Mb / s) Tantancewar fiber watsa.

b.Ethernet watsa: ta hanyar na zaɓi Ethernet module, hudu tashoshi na 10M/100M adaptive Ethernet sabis na gani fiber watsa za a iya gane.

Aikin Sabis: Ana iya sayan samfur ɗin tare da aikin tarho na sabis don gane sadarwar kasuwanci tsakanin masu ɗaukar hoto guda biyu.

d.RS232 bayanai: Samfurin yana samar da tashar bayanai asynchronous RS232. Adadin bayanan yana daidaita kansa ƙasa da 115.2Kb/s, kuma tsarin bayanan yana daidaita kansa.

f.Switch quantity interface: Za'a iya sanye samfurin tare da madaidaicin madaidaicin fitarwa na relay, wanda za'a iya amfani dashi don ƙararrawa ko sarrafawa.
