Optical transceiver ndiyo inogumira midziyo yekufambisa kwemasaini.

1. Optical transceiver mhando:
Optical transceiver chishandiso chinoshandura akawanda E1 (chiyero chekutumira data kune hunde mitsara, kazhinji pachiyero che 2.048Mbps, chiyero ichi chinoshandiswa muChina neEurope) kuita masaini masaini uye anoaendesa (basa rayo guru nderekuziva electro- optical).uye kushandura-kune-magetsi).Optical transceivers ane mitengo yakasiyana zvichienderana nehuwandu hweE1 ports inotumirwa.Kazhinji, diki diki transceiver inogona kutumira 4 E1, uye yazvino yakakura transceiver yemaziso inogona kutumira 4032 E1.

Optical transceivers akakamurwa kuita analog optical transceivers uye digital optical transceivers:
1) Analog optical transceiver

Iyo analog optical transceiver inotora iyo PFM modulation tekinoroji kufambisa chiratidzo chemufananidzo munguva chaiyo, inova ndiyo inonyanya kushandiswa panguva ino.Magumo ekutumira anotanga aita PFM modulation pane analogi vhidhiyo chiratidzo, uye yozoita yemagetsi-optical shanduko.Mushure mekunge chiratidzo chemaziso chapfuudzwa kumagumo ekugamuchira, inoita optical-to-electrical conversion, uye yozoita PFM demodulation kudzoreredza chiratidzo chevhidhiyo.Nekuda kwekushandiswa kwePFM modulation tekinoroji, kureba kwekufambisa kunogona kusvika nyore kusvika makumi matatu Km, uye kureba kwekutapurirana kwezvimwe zvigadzirwa kunogona kusvika 60 Km, kana kunyange mazana emakiromita.Uye zvakare, chiratidzo chemufananidzo chine kushomeka kushoma mushure mekutapurirana, ine yakakwira chiratidzo-kune-ruzha chiyero uye kudiki kusiri mutsara kukanganisa.Nekushandisa wavelength division multiplexing tekinoroji, iyo bidirectional kutapurirana kwemufananidzo uye masaini edhata anogonawo kuitika pane imwe optical fiber kuzadzisa izvo chaizvo zvinodikanwa zvekutarisisa mapurojekiti.

Nekudaro, iyi analog optical transceiver inewo zvimwe zvayakaipira:
a) Kugadzirisa kugadzirisa kwakaoma;
b) Zvakaoma kuona ma-multi-channel image transmission nefiber imwe chete, uye kuita kwacho kuchaderedzwa.Parizvino, rudzi urwu rweanalog optical transceiver inogona kungoendesa mifananidzo ye-4-channel pane imwe fiber;
c) Sezvo iyo analog modulation uye demodulation tekinoroji inoshandiswa, kugadzikana kwayo hakuna kukwirira zvakakwana.Nekuwedzera kwekushandisa nguva kana kuchinja kwemaitiro ezvakatipoteredza, kushanda kwe transceiver optical kuchachinjawo, izvo zvinounza kumwe kusagadzikana kune purojekiti.

2) Digital optical transceiver
Sezvo tekinoroji yedhijitari iine mabhenefiti ari pachena mune zvakawanda zvichienzaniswa neyechinyakare analogi tekinoroji, sezvakangoita tekinoroji yedhijitari yakatsiva tekinoroji yeanalogi muminda yakawanda, iyo digitization ye optical transceiver zvakare chiitiko chisingadzivisike.Parizvino, pane kunyanya maviri tekinoroji modhi yedhijitari mufananidzo optical transceiver: imwe ndeye MPEG II mufananidzo compression digital optical transceiver, uye imwe yacho isiri-kumisikidzwa dhijitari mufananidzo optical transceiver.Image compression Digital optical transceivers inowanzo shandisa MPEG II mufananidzo wekumanikidza tekinoroji, inogona kudzvanya mifananidzo inofamba muN × 2Mbps data hova uye kuiendesa kuburikidza neyakajairwa telecommunication yekutaurirana nzvimbo kana zvakananga kuburikidza neoptical fibers.Nekuda kwekushandiswa kweiyo mufananidzo compression tekinoroji, inogona kuderedza zvakanyanya iyo chiratidzo chekufambisa bandwidth.
