Traditional fiber vhidhiyo converters anoshandiswa kune point-to-point application. Fiber video converter inoiswa kumativi ose efiber optical, yakadai seyo inonyanya kushandiswa optical fiber Ethernet transceiver, inoshandisa optical fiber kubatanidza network yekombiyuta kumativi ose maviri. Uye mune dzimwe nguva dzakadai semagetsi, kuchengetedza mvura, nezvimwewo. Zviri pachena kuti networking mode inorambidzwa zvikuru. Panguva ino, tambo dze optical uye midziyo inodiwa kuti iite ring network. Optical midziyo inoda mhete network optical terminal: yepakati ndeye convergence, inoenderana yekutaurirana chiratidzo (foni/vhidhiyo/Ethernet/serial port, nezvimwewo), inochengetedza kudyara kweiyo optical tambo kusvika pamwero mukuru uye inovandudza chiyero chekushandiswa kweiyo fiber core. , izvo zvine musoro uye zvinodiwa mukushandisa zvinoshanda.

Chii chinonzi Ring Type Fiber Video Converter?

Mhete Type Fiber Vhidhiyo Inoshandura inoda michina ine angangoita maviri kana anopfuura optical ports, uye aya madoko anofanira kukwanisa kuona kuzvidzivirira kwekuzviporesa. Kana chero node pane chinongedzo ikatadza, inogona kusarudza otomatiki dzimwe nzira dzekutaurirana nepakati kuti ive nechokwadi chekutaurirana kwakajairika kwemanodhi asina mhosva.

Kuenzaniswa neyechinyakare analog tekinoroji, tekinoroji yedhijitari ine mabhenefiti ari pachena mune zvakawanda zvinhu. Sezvinongoita tekinoroji yedhijitari inotsiva tekinoroji yeanalogi muminda yakawanda, iyo digitization yemhete network optical transceivers zvakare chiitiko chisingadzivisike. Pane nzira mbiri huru dzehunyanzvi dzedhijitari vhidhiyo mhete network optical transceiver: imwe ndeye MPEGII mufananidzo compression dijitari mhete network fiber vhidhiyo inoshandura, uye imwe yacho yese-yedhijitari isina kumanikidzwa ring network fiber vhidhiyo inoshandura.

Kuenzaniswa neyechinyakare analog ring network fiber vhidhiyo inoshandura, iyo dijitari ring network vhidhiyo inoshandura ine zviri pachena zvakanakira:

1) Kureba kwekufambisa kureba: kusvika ku80Km kana kunyange kureba (120Km);
2) Tsigira vhidhiyo isina kurasikirwa yekuvandudza relay, saka akawanda-level transmission mode inogona kushandiswa;
3) Kupindira kwakaderera kwezvakatipoteredza uye hukuru hwekutapurirana;
4) Iyo inotsigirwa chiratidzo chesimba inogona kusvika 16 chiteshi kana kupfuura (32 chiteshi, 64 chiteshi, 128 chiteshi).
