FMUSER DTV4443 32-Channel IP QAM RF Modulator chinhu chinotyisa uye chakavimbika cheCATV nhepfenyuro masisitimu.

 

Inotsigira anosvika zana nemakumi maviri nemana ekupinda IP kuburikidza ne1024 GE ports, uye ine makumi matatu nembiri yekukwesha QAM modulating chiteshi nevatakuri vasiri padyo (3MHz ~ 32MHz) inobuda kuburikidza neRF inobuda. Kubhadhara kwayo-se-iwe-kukura modular dhizaini uye inochinjika dhizaini inopa kuwedzera scalability uye kuchinjika kune ichangoburwa chizvarwa CATV nhepfenyuro masisitimu.

 

Kwazvo PCR kugadzirisa, CA kusefa, PID remapping, uye PSI/SI editing zvese zvinotsigirwa, nekusvika mazana maviri nemakumi mashanu nenhatu PIDS kudzokorora pachiteshi. Iyo modulator inoburitsa 256 isiri-yakatarisana QAM vatakuri inoenderana neDVB-C (EN 32 300) uye ITU-T J.429 A/B, ine rutsigiro rweRS (83) encoding. Kutungamira kuri nyore neayo webhu-based network manejimendi.

 

Iine maficha epamberi uye dhizaini inoshanduka, iyo FMUSER DTV4443 32-Channel IP QAM RF Modulator isarudzo huru yeCATV nhepfenyuro masisitimu.
