Imodyuli ye-Optical luhlobo lwesixhobo sokunxibelelana kwenethiwekhi ukuqonda ukuguqulwa kwesiginali ye-photoelectric, kwaye i-transponder luhlobo lwezixhobo zokunxibelelanisa inethiwekhi ukuqaphela ukukhulisa ukukhulisa umqondiso wokukhanya kunye nokuguqulwa kwamaza.Nangona imodyuli ye-optical kunye ne-transponder zombini isekelwe kumgaqo wokuguqula i-photoelectric kwaye inokuqonda ukuguqulwa kwe-photoelectric, kodwa umsebenzi kunye nesicelo sahlukile, kwaye asinakuthatha indawo enye kwenye.Eli nqaku liza kukuxelela umahluko phakathi kweemodyuli zamehlo kunye nabaguquli ngokweenkcukacha ezinkulu.
Njengesixhobo sonxibelelwano sokudlulisa kunye nokufumana iimpawu ze-optical, imodyuli ye-optical isoloko isetyenziselwa kwiinkqubo zonxibelelwano zefiber optical ezifana neziko ledatha, inethiwekhi yezoshishino, i-computing yefu, kunye ne-FTTX.Ngokuqhelekileyo, iimodyuli ze-optical zixhasa ukutshintshwa okushushu, okunokusetyenziswa kwi-module slot yokutshintsha kwenethiwekhi, iiseva kunye nezinye izixhobo zenethiwekhi.Okwangoku, kukho iintlobo ezininzi zeemodyuli ze-optical kwimarike, njenge-1G SFP, 10 GSFP +, 25G SFP 28,40G QSFP +, 100G QSFP, 28,400G QSFP-DD iimodyuli ze-optical, njl. iijumpi zefiber optical okanye iintambo zothungelwano ukuqonda usasazo lwenethiwekhi kwimigama eyahlukeneyo, ukusuka kwi-30km ukuya kwi-160km.Ukongezelela, imodyuli ye-BiDi optical inokudlulisa kwaye ifumane iimpawu nge-fiber optical fiber, ilula ngokufanelekileyo i-wiring, iphucula umthamo wenethiwekhi, kunye nokunciphisa iindleko zesiseko se-cabling.Ngokufanayo, iimodyuli ze-WDM zochungechunge lwe-optical (okt, i-CWDM kunye ne-DWDM iimodyuli ze-optical) zingaphinda zisebenzise iimpawu ze-wavelengths ezahlukeneyo kwi-fiber optical efanayo, ebonwa ngokuqhelekileyo kwiinethiwekhi ze-WDM / OTN.
I-Transponder, ekwabizwa ngokuba yi-photoelectric wavelength converter okanye i-optical amplifier repeater, sisiguquli se-fiber media optical esidibanisa isidlulisi kunye nomamkeli.Inokwandisa umgama wothumelo lwenethiwekhi ngokuguqula ubude be-wavelength kunye nokukhulisa amandla optical, kwaye inomsebenzi wokukhulisa ngokulinganayo, ukukhutshwa kwexesha kunye nokuqatshelwa kweempawu ze-optical ezihlaziyiweyo. I-10G / 25G iphinda ikwazi ukuguqula i-fiber optical (njenge-fiber ephindwe kabini yokuguqulwa kwendlela enye ukuya kwi-fiber enye ye-bi-directional), ukuguqulwa kohlobo lwefayibha (i-multi-mode optical fiber ibe yi-single-mode optical fiber) kunye nokuphuculwa kwesignali ye-optical (ngokuguqula Isiginali ye-wavelength eqhelekileyo ngokuhambelana nenkcazo ye-ITU-T yobude bokuphakama ukuze kuphunyezwe uhlaziyo lokukhulisa, ukubunjwa kunye nokubeka ixesha kwakhona kwewotshi);Ngokuqhelekileyo isetyenziswe ngokudibanisa ne-EDFA fiber optic amplifier kunye ne-DCM dispersion compensator, Isetyenziswe ngokubanzi kwi-MAN, i-WDM networks, Ngokukodwa kwiinethiwekhi ze-DWDM ze-ultra-long-long.Ukuphindaphinda kwe-100G (oko kukuthi i-100G iphindaphinda i-multiplexing) iphuhliswe ngokukodwa kwi-10G / 40G / 100G yokudluliselwa ukuguqula i-interfaces optical ezahlukeneyo ngokuguquguqukayo.Oko kukuthi, i-repeater ye-100G inokuxhasa ukudibanisa okuguquguqukayo kwe-10 GbE, i-40 GbE kunye ne-100 GbE, kwaye ingasetyenziselwa kwinethiwekhi yezoshishino, inethiwekhi yepaki, i-data center interconnection, i-MAN kunye nezinye izicelo ezikude.
Ukusuka apha ngasentla, zombini imodyuli ye-optical kunye nesiphindaphindayo inokuguqula imiqondiso yombane ibe yimiqondiso yokubona, kodwa umahluko phakathi kwezi zimbini:
1. Imodyuli ye-optical interface ye-serial, idlulisa kwaye ifumane iimpawu ngaphakathi kwimodyuli ye-optical, ngelixa i-repeater i-interface ehambelanayo kwaye kufuneka ihambelane nemodyuli ye-optical ukuqonda ukuhanjiswa kwesignali.Imodyuli ye-optical, elinye icala lisetyenziselwa ukuhambisa iimpawu kwaye elinye icala lisetyenziselwa ukufumana iimpawu.
2. Nangona imodyuli ye-optical inokuqonda ukuguqulwa kwe-photoelectric, i-transponder inokuguqula izibonakaliso ze-photoelectric ezivela kwii-wavelengths ezahlukeneyo.
3. Nangona i-converter ingakwazi ukuphatha ngokulula iimpawu ezihambelanayo eziphantsi, inobukhulu obukhulu kunye nokusetyenziswa kwamandla aphezulu xa kuthelekiswa nemodyuli ye-optical.
Ngamafutshane, i-transponder inokubonwa njengemodyuli ye-optical edityanisiweyo, igqiba ukuhanjiswa kwenethiwekhi ye-WDM ekude ukuba imodyuli ye-optical ayikwazi.
I-Shenzhen HDV Phoelectron Technology Ltd. imveliso ekhethekileyo yabavelisi bemodyuli yamehlo.Hayi kuphelaI-ONUuthotho,OLTseries, switsha series, zonke iintlobo zeemodyuli ziyafumaneka, Abo badinga ukutyelela kwaye bazi ngakumbi bayamkelwa.
