Mukuvaka nekushandiswa kwetiweki, sezvo kureba kwekufambisa kwetambo yetiweki kazhinji 100 metres, zvinodikanwa kushandisa michina yekudzosera senge optical fiber transceivers kana uchiendesa kure-kure-kure kufambisa network.Optical fiber transceiversanowanzo shandiswa munzvimbo dzinoshanda dzetiweki uko tambo dzeEthernet dzisingakwanise kuvhara uye mafiber optical anofanirwa kushandiswa kuwedzera kureba kwekufambisa.Saka, chii chinofanira kutariswa kana uchishandisa fiber optic transceivers?

1. Kubatana kwe optical fiber interface inofanira kubhadhara kune imwechete-mode uye yakawanda-mode matching: single-mode transceivers inogona kushanda pasi pe-single-mode fiber uye multi-mode fiber, asi multi-mode fiber transceivers haigoni kushanda pasi pe-single-mode. fiber.Nyanzvi yakataura kuti imwe-modhi michina inogona kushandiswa ne-multi-mode fiber kana iyo optical fiber transmission kureba ipfupi, asi nyanzvi ichiri kukurudzira kuti itsive iyo inoenderana fiber transceiver zvakanyanya sezvinobvira, kuitira kuti midziyo ishande zvakanyanya. zvakatsiga uye zvakavimbika.Packet kurasikirwa chiitiko.

2. Kusiyanisa michina imwe chete-fiber uye mbiri-fiber: iyo transmitter port (TX) ye-transceiver kune imwe mugumo we-double-fiber device yakabatana nechiteshi chekugamuchira (RX) che transceiver kune rumwe rutivi.Zvichienzaniswa neaviri-fiber zvishandiso, single-fiber zvishandiso zvinogona kudzivirira dambudziko rekuiswa zvisirizvo kweiyo transmitter port (TX) uye inogamuchira chiteshi (RX) panguva yekushandiswa.Nemhaka yekuti i-single-fiber transceiver, imwe chete optical port ndiyo TX uye RX panguva imwe chete, uye fiber optical yeSC interface inogona kuvharirwa mukati, iyo iri nyore kushandisa.Uye zvakare, imwe-fiber michina inogona kuchengetedza kushandiswa kwefiber uye nekunyatso kudzikisa mutengo wakazara weyekutarisa mhinduro.

3. Ngwarira kuvimbika uye kutonhora kwemhepo ye optical fiber transceiver midziyo: iyo optical fiber transceiver pachayo ichaita kupisa kwakanyanya kana yakashandiswa, uye optical fiber transceiver haigoni kushanda zvakanaka kana kutonhora kwakanyanya.Naizvozvo, yakakura yekushanda tembiricha renji inogona pasina mubvunzo kudzikisa mukana wekutadza kusingatarisirwi kwemidziyo inoda kumhanya kwenguva yakareba, uye kuvimbika kwechigadzirwa kwakakwira.Mazhinji emakamera ekumberi-ekupedzisira emheni yekudzivirira performance monitoring system akaiswa munzvimbo yekunze yakavhurika-mhepo, uye njodzi yekukuvadza mheni yakananga kumidziyo kana tambo yakakwira.Pamusoro pezvo, zvakare inotarisisa kukanganiswa kwemagetsi senge mheni yakawandisa, simba system inoshanda overvoltage, electrostatic discharge, nezvimwe, izvo zvinogona kukonzeresa kukuvadzwa kwemidziyo zviri nyore, uye mumatambudziko akaomarara zvinogona kukonzera iyo yese yekutarisa system kuremara.

4. Kunyangwe kutsigira yakazara-duplex uye hafu-duplex: Mamwe fiber optic transceivers pamusika anogona chete kushandisa yakazara-duplex nharaunda uye haigone kutsigira hafu-duplex, sekubatanidza kune mamwe mabhureki ekuchinja kana hubs, uye inoshandisa hafu- duplex modhi, inozokonzeresa kukakavara kwakakomba uye kurasikirwa kwepaketi.
