Imojula ye-Optical iwuhlobo lwemishini yokuxhumanisa inethiwekhi ukuze ibone ukuguqulwa kwesignali yesithombe kagesi, futhi i-transponder iwuhlobo lwezisetshenziswa zokuxhumanisa inethiwekhi ukuze zibone ukukhulisa isignali yokukhanya nokuguqulwa kwe-wavelength. Nakuba i-module optical kanye ne-transponder kokubili ngokusekelwe kumgomo wokuguqulwa kwe-photoelectric futhi ingakwazi ukubona ukuguqulwa kwe-photoelectric, kodwa umsebenzi nokusetshenziswa kuhlukile, futhi akukwazi ukufaka esikhundleni somunye nomunye. Lesi sihloko sizokutshela umehluko phakathi kwamamojula optical nabaguquli ngemininingwane enkulu.
Njengemishini yokuxhumana yokudlulisa nokwamukela amasignali optical, imojula ye-optical ivame ukusetshenziswa ezinhlelweni zokuxhumana ze-fiber optical njengesikhungo sedatha, inethiwekhi yebhizinisi, i-cloud computing, ne-FTTX. Ngokuvamile, amamojula optical asekela ukushintshashintsha okushisayo, okungasetshenziswa ku-module slot yokushintsha kwenethiwekhi, amaseva namanye amadivaysi enethiwekhi. Njengamanje, kunezinhlobo eziningi zamamojula optical emakethe, njenge-1G SFP, 10 GSFP+, 25G SFP 28,40G QSFP+, 100G QSFP, 28,400G QSFP-DD amamojula optical, njll. Ngokuvamile asetshenziswa ngezinhlobo ezahlukene ze i-optical fibre jumpers noma izintambo zenethiwekhi ukuze ubone ukudluliswa kwenethiwekhi emabangeni ahlukene, asukela ku-30km kuya ku-160km. Ngaphezu kwalokho, i-BiDi optical module ingadlulisela futhi yamukele amasignali nge-fiber optical eyodwa, yenza lula izintambo, ithuthukise umthamo wenethiwekhi, futhi yehlise izindleko zengqalasizinda yekhebula. Ngokufanayo, amamojula optical ochungechunge lwe-WDM (okungukuthi, i-CWDM ne-DWDM optical modules) angaphinda asebenzise amasiginali amaza ahlukene wamaza kuya ku-fiber optical efanayo, evame ukubonakala kumanethiwekhi e-WDM/OTN.
I-Transponder, eyaziwa nangokuthi i-photoelectric wavelength converter noma i-optical amplifier repeater, i-optical fiber media converter ehlanganisa isidlulisi nomamukeli. Ingakwazi ukwandisa ibanga lokudluliswa kwenethiwekhi ngokuguqula ubude be-wavelength kanye nokukhulisa amandla optical, futhi inomsebenzi wokukhulisa okulinganiselayo, ukukhishwa kwesikhathi kanye nokuqashelwa kwezimpawu ze-optical ezivuselelwe. I-10G / 25G ephindaphindayo ingakwazi ukubona ukuguqulwa kwe-fiber optical (njengokuguqulwa kwe-fiber ephindwe kabili yendlela eyodwa ibe yi-single-fiber bi-directional), ukuguqulwa kohlobo lwe-fiber (i-multi-mode optical fiber ibe yi-single-mode optical fiber) kanye nokuthuthukiswa kwesignali yokubona (ngokuguqula isignali evamile ye-wavelength optical ngokuhambisana nencazelo ye-ITU-T wavelength ukuze kuzuzwe ukukhuliswa kabusha kokukhulisa, ukubunjwa kanye nokwenza kabusha isikhathi sewashi); Ivamise ukusetshenziswa ngokuhlanganiswa ne-EDFA fibre optic amplifier kanye ne-DCM dispersion compensator, Isetshenziswa Kakhulu kumanethiwekhi e-MAN, WDM, Ikakhulukazi kumanethiwekhi e-DWDM ebanga elide. I-100G repeater (okungukuthi i-100G multiplexing repeater) ithuthukiswe kakhulu ukudluliselwa kwe-10G / 40G / 100G ukuze iguqule ukuxhumana okuhlukile okubonakalayo kalula. Okusho ukuthi, i-100G repeater ingasekela inhlanganisela eguquguqukayo ye-10 GbE, 40 GbE ne-100 GbE, futhi ingasetshenziswa kunethiwekhi yebhizinisi, inethiwekhi yepaki, ukuxhumana kwesikhungo esikhulu sedatha, i-MAN nezinye izinhlelo zokusebenza ezikude.
Kusukela kulokhu okungenhla, kokubili i-optical module kanye ne-repeater ingaguqula amasignali kagesi abe amasignali optical, kodwa umehluko phakathi kwakho kokubili:
1. Imojula ye-optical iyisixhumi esibonakalayo se-serial, idlulise futhi yamukele amasignali ngaphakathi kwemojula ye-optical, kuyilapho i-repeater iyisixhumi esibonakalayo esihambisanayo futhi kufanele ihambisane nemojula ye-optical ukuze ibone ukudluliswa kwesignali. Imojula ye-optical, uhlangothi olulodwa lusetshenziselwa ukudlulisa amasignali kanti olunye uhlangothi lusetshenziselwa ukwamukela amasignali.
2. Nakuba i-optical module ingakwazi ukubona ukuguqulwa kwe-photoelectric, i-transponder ingakwazi ukuguqula amasignali e-photoelectric kusuka kumaza ahlukene.
3. Nakuba isiguquli singakwazi futhi ukuphatha kalula amasiginali ahambisanayo anezinga eliphansi, inosayizi omkhulu kanye nokusetshenziswa kwamandla okuphezulu uma kuqhathaniswa nemojula ye-optical.
Ngamafuphi, i-transponder ingabonakala njengemodyuli ye-optical ehlukanisiwe, iqedela ukuhanjiswa kwenethiwekhi ye-WDM ekude ukuthi i-module optical ayikwazi.
I-Shenzhen HDV Phoelectron Technology Ltd. ukukhiqizwa okukhethekile kwabakhiqizi be-optical module. Hhayi kuphelaI-ONUuchungechunge,OLTuchungechunge,shintshauchungechunge, zonke izinhlobo zamamojula ziyatholakala, Labo abadinga ukuvakashela futhi bazi okwengeziwe bayamukelwa.
