Yedunyikafoni optical transceiversdzakasimukira nekukurumidza nekuvandudzwa kweindasitiri yekutarisa.Kubva paanalogi kuenda kudhijitari, uyezve kubva kudhijitari kuenda kune yakakwirira-tsanangudzo, ivo vanogara vachifambira mberi.Mushure memakore ekuunganidza kwehunyanzvi, ivo vakakura kusvika padanho rakakura kwazvo.Nharembozha optical transceivers haina kuita budiriro yakakura muhunyanzvi, asi mamwe mabasa akakosha anogona kuvandudzwa uye kukwenenzverwa mumashandisirwo akapatsanurwa.Kusanganisira kuvandudzwa kwemaitiro echinyakare senge system kugadzikana uye kugona, iyi zvakare simba rekufambisa refoni optical transceiver vagadziri kutsvaga vasinganeti mabhindauko.

Iko hakuna muganho wekusimudzira uye hunyanzvi, uye kudzikamisa kuita ndicho chinhu chinonyanya kukosha.Kana tekinoroji yematransceivers optical yemafoni yanyatsokura, vagadziri vazhinji vanotendeudzira kusimudzira kwavo kutarisa kune kuvandudzwa kwekuita kwechigadzirwa.Parizvino, kuita kwemaoptical transceivers kunonyanya kuvandudzwa kubva kune anotevera pfungwa:

Yokutanga ndeyekugadzirwa kwe-single-mode.Iyo optical fiber inogona kukamurwa kuva multi-mode uye imwe-mode maererano nekufambiswa kwechiedza mairi.Single-modhi inogona kudzivirira zvachose modal dispersion, uye ine yakanaka kutapurirana mhedzisiro, haina kukanganiswa nyore, uye ine hombe yekufambisa frequency bandwidth uye yakakura kutapurirana simba.Chinja kune hombe-chaiyo, kutapurirana kure-kure.

Yechipiri ndeye modular uye hybrid yekuwana dhizaini.Iyo modular dhizaini inoshanduka uye inoshanduka, iyo inogona kupa anowedzera mabasa ekuvandudza system;nemaitiro edhijitari, kubatanidzwa kweSDI tekinoroji, uye kugarisana kwezvakasiyana zvigadzirwa zvinounza kusagadzikana kune vanogadzira.Naizvozvo, .Pamusoro peiyo modular dhizaini, hybrid yekuwana dhizaini inodiwa zvakare, ichipa RJ-45 network interface, BNC interface, nezvimwewo mumudziyo, kuitira kuti ese masaini eanalog uye network masaini anogona kufambiswa mune imwechete optical transceiver.

Yetatu ndeyekupfumisa mafomu ekunyorera efoni optical transceivers.Iyi tekinoroji ichadzikisa zvakanyanya huwandu hwezvigadzirwa kune imwechete kana maviri zvirevo, uye vatengi vanogona kuzviwana pamadiro.Zvinoenderana nemamiriro eiyo optical fiber access point, zviri nyore kuronga, uye nhare optical transceiver haichazoganhurwa nepoint-to-point, node, ring, aggregation, etc. Chigadzirwa chimwe chete chinoenderana nenzira dzese dzekuwana. , zvakanyanya kuderedza nhamba ye optical fibers inoshandiswa.

Yechina ndeyekushandisa tekinoroji yemultiplexing (iyo general term yeEDM, TDM, uye WDM), iyo inonyanya kugadzirisa dambudziko rediki rekutapurirana kwefiber imwe chete, kunyanya kushandiswa kweHD-SDI, iyo inobata bandwidth hombe uye ine. bhizimisi guru guru.Kana iyo tekinoroji yemultiplexing uye tekinoroji yewavelength division multiplexing tekinoroji inogona kubatanidzwa, kugona kunogona kuvandudzwa kakawanda.Naizvozvo, kutsvagisa nekusimudzira tekinoroji yemultiplexing inonyanya kukosha.
