Ma transceivers owoneka ndi zida zotumizira ma siginecha. Ma transceivers optical akunja ali ndi ukadaulo wokhwima koma ndi okwera mtengo. Ngakhale ma transceivers optical apanyumba sali okhwima muukadaulo, sakhala okwera mtengo kwambiri kuti athane ndi zamkati. Ndiye kusankha kwa optical transceivers ndi chiyani?

Chenjezo pogula ma transceivers opangira: Kuchokera pa chizindikiro chotumizidwa ku fiber optical, ma transceivers optical amatha kugawidwa kukhala ma transceivers opangidwa ndi analogi pogwiritsa ntchito teknoloji ya analogi ndi ma transceivers opangidwa ndi digito pogwiritsa ntchito luso lamakono. Mfundo yogwira ntchito ya analogi optical transceiver sichinthu choposa kusinthasintha ndi kuchotseratu, kusefa ndi kusakaniza chizindikiro, ndi zina zotero. Kaya ndi LED kapena LD, mawonekedwe ake a photoelectric modulation si ofanana. Mu njira yotumizira chizindikiro, kusokoneza, kusokoneza ndi mavuto ena osapeŵeka pakukonza analogi ndizosapeŵeka, ndipo pali matekinoloje osagonjetseka pakufalitsa kwakukulu ndi kufalitsa kosakanikirana kwa mautumiki ambiri. zovuta.

Mkhalidwe wa digito optical transceivers ndi wosiyana. Pali zigawo ziwiri zokha za "fiber" ndi "zopanda CHIKWANGWANI" mu ulusi wa kuwala. Chifukwa chake, mzere wa gwero la kuwala siwokwera kapena pafupifupi palibe chofunikira, potero kupewa kutayika kwa chizindikiro pakukonza. Kuphatikiza apo, ma transceivers owoneka bwino a digito ndi osavuta kukwaniritsa njira zambiri komanso kuphatikizika kosakanikirana kwa ma sign angapo. Popeza amangosandulika kukhala zizindikiro za digito, kutumiza kwa njira zambiri ndi zizindikiro zambiri zingatheke mosavuta mothandizidwa ndi teknoloji ya TDM (Time Division Multiplexing). Opanga ma transceiver omwe alipo atha kutumiza zithunzi 10 zamavidiyo zenizeni zenizeni panjira imodzi panthawi imodzi.

Optical fiber network topology, optical fiber network topology imatsimikizira mtundu wa transceiver ya kanema. Malingana ndi topology ya optical fiber transmission network, kuwonjezera pa ma transceivers optical point-to-point transceivers, palinso ma transceivers opangidwa ndi ma node-mtundu ndi mphete. Makanema amtundu wa node optical transceiver amaphatikiza ma node akutsogolo kukhala maukonde a unyolo kapena maukonde amitengo. Makina a node amayamba kulandira chizindikiro pa node iliyonse, amasinthitsa kukhala chizindikiro chamagetsi, kenaka amasinthanitsa ndi kuchulukitsa chizindikirocho ndi node yapafupi. Pambuyo pa kutembenuka kwa photoelectric, teknoloji ya WDM imagwiritsidwa ntchito pochulukitsa. Gwiritsani ntchito kuwala kwa fiber pofalitsa. Palibe kutembenuka kwa analogi kupita ku digito komwe kumachitidwa pa node iliyonse, zomwe zimachepetsa kuchepetsedwa kwa chizindikiro.

Kuthamanga kwa transceiver ya kuwala kumathamanga, chinsalucho chikuwoneka bwino, ndipo chingagwiritsidwe ntchito mumitundu yonse yakunja. Ili ndi magwiridwe antchito ambiri ndipo imagwiritsidwa ntchito kwambiri m'makampani.
