I-transceiver ye-Optical sisixhobo esiguqula imiqondiso emininzi ye-E1 ibe yimiqondiso yokubona.I-Optical transceiver ikwabizwa ngokuba yi-optical transmission equipment.Ii-transceivers ze-Optical zinamaxabiso ahlukeneyo ngokwenani le-E1 (oko kukuthi, i-2M) izibuko ezithunyelwayo.Ngokuqhelekileyo, i-transceiver encinci ye-optical inokuhambisa i-4 E1s.I-transceiver enkulu yangoku ebonakalayo inokuhambisa i-4032 E1s, kwaye i-E1 nganye iquka iifowuni ze-30.Ngoko, i-transceiver ye-optical 2m ithetha ntoni, kwaye yintoni ubudlelwane phakathi kwe-transceiver optical E1 kunye ne-2M?

Iindidi ze-transceivers optical, i-transceivers optical zihlulwe zibe ziindidi ze-3: PDH, SPDH, SDH.I-PDH i-transceivers optical transceivers i-transceivers ebonakalayo encinci, isetyenziswa ngokubanzi ngababini, ebizwa ngokuba yi-point-to-point applications, kunye namandla abo ngokubanzi yi-4E1, 8E1, kunye ne-16E1.I-SDH i-transceiver ebonakalayo inomthamo omkhulu, ngokubanzi i-16E1 ukuya kwi-4032 E1, i-SPDH i-transceiver optical, phakathi kwePDH kunye ne-SDH.Ngokuqhelekileyo, i-transceiver ebonakalayo ingaphezulu kwe-PDH ye-optical transceiver, eyisixhobo sokuguqula i-photoelectric.Ngokuqhelekileyo, i-transceiver ye-optical kunye ne-optical port enye kunye ne-4 yezinga le-2M izibuko zombane zezona ziqhelekileyo.Abaqhubi beTelecom bahlala beyisebenzisa ukuhambisa imiqondiso yelizwi.Kwiofisi ephakathi, i-terminal optical iguqula i-2M yombane yombane ibe yisignali ye-optical kwaye idlulisele kwi-cable optical.Emva kokufikelela ekupheleni komsebenzisi, umqondiso we-optical uguqulwa ube ngumqondiso wombane we-2M, oko kukuthi, inkonzo ye-2M ithunyelwa kwizixhobo zezwi ezifana ne-PCM.Kwaye i-fiber optic transceivers isetyenziswa kakhulu kunxibelelwano lwedatha.Kwakhona luhlobo lwezixhobo zokuguqula i-photoelectric.Ngokubanzi, kukho ngaphezu kwesinye izibuko optical kunye namazibuko e-Ethernet aliqela.Iguqula izibonakaliso ezibonakalayo kwiimpawu ze-Ethernet, ezisetyenziselwa ukuthumela iinkonzo zedatha kwizixhobo zonxibelelwano lwedatha ezifana nee-routers okanye iiswitshi.

Kwi-transceivers optical, i-2M ngokusisiseko ithetha ukuba i-wavelength yokugqibela ye-1550 ine-bandwidth ye-2M, esetyenziselwa ukuhambisa idatha yokulawula i-485, kwaye kukho i-1.25G, i-155M kunye nokunye okunjalo, leyo yi-bandwidth efunekayo yokuhanjiswa kwevidiyo, ngokusisiseko i-channel ye-1 yevidiyo. iimfuno 155M.Ii-transceivers ze-Optical E1 kunye ne-2M ngokwenene zahluke kuphela kwintetho.I-E1 yimbonakaliso yeqela kumgangatho waseYurophu wePDH (ehambelana neqela eliqhelekileyo laseMntla Melika yi-T1, okt 1.5M).Kumgangatho waseYurophu izinga le-E1 yi-2M, ngoko ke i-2M isoloko isetyenziselwa ukumela i-E1.Kunokuthiwa kwakhona ukuba i-E1 ligama lesayensi kwaye i-2M ligama eliqhelekileyo.Ngexesha le-SDH, izinga le-VC12 (kunye ne-TU-12) kwi-SDH yobudlelwane be-multiplexing yayisondele kwi-2M (okwenene kungekhona i-2048K), abanye abantu baphinda babize le 2M, eyona nto ingachanekanga.Kwizibuko le-E1 kwisixhobo, lidla ngokubizwa ngokuba yi-2M port, kwaye kufuneka ibe bubuchule be-E1 ukuze ichaneke.Ngokuhambelanayo, izibuko le-34M kufuneka libe yi-E3 port, kwaye i-45M port kufuneka ibe yi-DS3 port.Izibuko le-140M yi-E4 port.
