Ingcaciso yeMveliso

I-ZTX1800 luhlobo oluqhelekileyo lokusebenza okuphezulu kwe-1550nm yokuguqula ukuhambisa umbane ngombane kunye nokusebenza okuphezulu kokuhambisa umbane. Umthombo opheleleyo wokukhanya usebenzisa ububanzi bebhendi encinci, ingxolo ephantsi, iliza eqhubekayo ye-DFB laser, ecetywayo ukunciphisa ifuthe lokusasazeka. Ngenxa yokwamkelwa kophawu lwehlabathi lwezixhobo eziphambili kunye nenkqubo yolawulo lwetekhnoloji yolawulo lwetekhnoloji, itekhnoloji yolawulo lwenethiwekhi ye-SMNP, izikhombisi zomsebenzi wobuchwephesha bomatshini zilinganisa ngokupheleleyo umgangatho wezixhobo ezifanayo ezingenisiweyo. Inokubonelela ngemifanekiso ekumgangatho ophezulu, idigital okanye icinezelweyo umqondiso wedijithali wokuhambisa umgama omde kunxibelelwano lwekhebula kunye nokunxibelelana ngomnxeba.

Iimbonakalo

(1) Umgangatho ophezulu: Itekhnoloji yomthombo we-microwave kunye ne-RF itekhnoloji yangaphambi kokugqwetha iqinisekisa ukuba inkqubo inokufumana iithagethi ze-CTB, CSO, kunye ne-SBS kwimeko yokusebenza ngokugqwesileyo kwe-CNR≥52dB.

(2) Ukuba bhetyebhetye: Ekuqinisekiseni inkqubo yokusebenza kweCSO ephezulu, itekhnoloji yokumodareyitha yesigaba semodareyitha yangaphandle yandisa amandla e-optical kwifayibha ukuze ifumane ukuhanjiswa kwemigama emide, kunye nomhlaba olungelelanisiweyo weSBS, 13, 16,18dB, AGC / Imowudi ye-MGC inokukhethwa, intsimi eyenziwe nge-OMI iyenze ilungele ukuhanjiswa kweenethiwekhi ezahlukeneyo.

(3) Ukuthenjwa: I-19 "1U rack esemgangathweni, eyakhelwe-ngaphakathi ekusebenzeni okuphezulu kokuhambisa umbane, inokusebenza kugcino kwi-85 ~ 265Vac City Network Voltage, kwi-MS-level switching automatic; Chassis ukupholisa ulawulo lobushushu oluzenzekelayo.

(4) Intuitive: Imodyuli yangaphandle kunye nelaser zezona zinto zibiza kakhulu kumatshini, umatshini oxhotyiswe ngemicroprocessor ujonga imeko yokusebenza kwemodyuli yangaphandle kunye nelaser, iphaneli yeLCD yefestile ibonisa iiparameter zokusebenza.

(5) Uhlobo lwenethiwekhi: Khetha isiQinisekiso sobume bendawo yokubeka esweni ukuhlangabezana nomgangatho wesizwe kwaye uhambelane nomgangatho we-SCTE HMS, yenza ukuba ulawulo lwenethiwekhi lubenakho.

(6) Ukunikezelwa kwamandla okucoca: isebenzisa izinto zealuminium, iswitshi enokucinywa yePSU, isebenze kunye ne-86 ~ 265VAC, inokuthi ithathelwe indawo yi -48VDC ngokulula.
