Isingeniso esiyisisekelo semojula ye-optical
Imodyuli ye-optical yakhiwe ngamadivaysi e-optoelectronic, ama-circuits asebenzayo kanye ne-optical interfaces. Amadivayisi we-optoelectronic afaka izingxenye ezimbili: ukudlulisa nokwamukela. Ngamafuphi, umsebenzi we-optical module ukuguqula isignali kagesi ibe isignali ye-optical ekupheleni kokuthumela. Ngemuva kokuthi isignali ye-optical idluliselwe nge-fiber optical, ukuphela kokwamukela kuguqula isignali ye-optical ibe isignali kagesi.
Ingxenye yokudlulisela ithi: isignali kagesi efakiweyo yezinga elithile lebhithi icutshungulwa yi-chip yedrayivu yangaphakathi, bese ishayela i-semiconductor laser (LD) noma i-light emitting diode (LED) ukuze ikhiphe isignali yokubona eshintshiwe yezinga elihambisanayo. Isifunda sokulawula okuzenzakalelayo samandla okukhanya kwangaphakathi sihlonyiselwe ukugcina amandla esignali ye-optical okukhiphayo ezinzile.
Ingxenye eyamukelayo ithi: imojula yokufaka isignali yokubona enezinga elithile lebhithi iguqulwa ibe isignali kagesi nge-optical discover diode, futhi isignali kagesi enezinga lebhithi elihambisanayo liyaphuma ngemva kwe-preamplifier.
-Umqondo oyisisekelo we-optical module-
Imojula ye-port-optical yigama elijwayelekile lezigaba ezahlukahlukene zamamojula, ngokuvamile libhekisa kumojula ehlanganisiwe ye-transceiver optical.
-Umsebenzi we-optical module-
Umsebenzi wawo ukumane ubone ukuguqulwa phakathi kwamasignali optical kanye namasignali kagesi.
-Optical module isakhiwo-
Imojula ye-optical ngokuvamile yakhiwa i-optical transmitter, i-optical receiver, i-functional circuit kanye ne-optical (electrical) interface.
Ku-transmitter, i-chip yomshayeli icubungula isignali kagesi yasekuqaleni, bese ishayela i-semiconductor laser (LD) noma i-light emitting diode (LED) ukuze ikhiphe isignali yokubona eshintshile.
Ichweba lisekupheleni kokwamukela. Ngemva kokungena kwesignali yokubona, iguqulelwa kusignali kagesi nge-optical discover diode, bese ikhipha isignali kagesi nge-preamplifier.
-Ukuhlukaniswa kwemodi ye-Optical-
-Umlando wokuthuthukiswa kwemodi ye-optical-
- Isingeniso sokupakishwa kwe-optical module-
Kunezinhlobonhlobo zamazinga okupakisha amamojula optical, ikakhulukazi ngoba:
》Isivinini sokuthuthuka sobuchwepheshe bokuxhumana ngefiber optical sishesha kakhulu. Ijubane lemojula ye-optical liyakhula, futhi ivolumu nayo iyancipha, ukuze njalo eminyakeni embalwa, amalebula amasha okupakisha azokhishwa.
olunembile Kunzima futhi ukuhambisana phakathi kwezindinganiso zokupakisha ezintsha nezindala.
》Izimo zohlelo lokusebenza zamamojula optical zihlukahlukene. Amabanga ahlukene okudlulisela, izidingo zomkhawulokudonsa, nezindawo zokusetshenziswa, ezihambisana nezinhlobo ezahlukene zefiber optical ezisetshenziswayo, amamojula optical nawo ahlukile.
Imbobo ye-GBIC
I-GBIC i-Giga Bitrate Interface Converter.
Ngaphambi kuka-2000, i-GBIC yayiyi-optical module ethandwa kakhulu futhi iyifomu lemojula yegigabit esetshenziswa kakhulu.
Ichweba le-SFP
Ngenxa yobukhulu be-GBIC, i-SFP yavela kamuva futhi yaqala ukufaka esikhundleni se-GBIC.
I-SFP, igama eligcwele le-Small Form-factor Pluggable, iyimojula encane eshintshwayo eshintshwayo. Usayizi wayo omncane uhlobene nokupakishwa kwe-GBIC. Usayizi we-SFP mncane ngohhafu kunalowo wemojula ye-GBIC, futhi ngaphezu kokuphindwe kabili inani lamachweba lingacushwa kuphaneli efanayo. Mayelana nomsebenzi, kukhona umehluko omncane phakathi kwakho kokubili, futhi kokubili kusekela ukuxhuma okushisayo. Umkhawulokudonsa omkhulu osekelwa yi-SFP yi-4Gbps
I-XFP yomlomo
I-XFP iyi-10-Gigabit Small Form-factor Pluggable, engaqondwa lapho uthi shazi. Kuyi-10-Gigabit SFP.
I-XFP yamukela imojuli yeserial yesiteshi esisodwa enesivinini esigcwele exhunywe yi-XFI (i-10Gb serial interface), engangena esikhundleni se-Xenpak kanye nokuphuma kwayo.
Ichweba le-SFP+
I-SFP+, njenge-XFP, iyimojula ye-10G yokubona.
Ubukhulu be-SFP+ buyafana nobe-SFP. Ihlangene kakhulu kune-XFP (yehliswe cishe ngo-30%), futhi ukusetshenziswa kwayo kwamandla nakho kuncane (kuncishiswe eminye imisebenzi yokulawula isignali).
O SFP28
I-SFP enezinga le-25Gbps ngokuyinhloko ngenxa yokuthi amamojula we-40G kanye ne-100G optical ayebiza kakhulu ngaleso sikhathi, ngakho-ke lolu hlelo lokuguqulwa kokuyekethisa lwenziwa.
QSFP/QSFP+/QSFP28/QSFP28-DD
I-Quad Small Form-factor Pluggable, isixhumi esibonakalayo se-SFP eneziteshi ezine. Kusetshenziswe ubuchwepheshe obuningi bokhiye abavuthiwe ku-XFP kulo mklamo. I-QSFP ingahlukaniswa ibe yi-4 ngokuya ngesivinini × 10G QSFP+, 4 × 25G QSFP28, 8 × 25G QSFP28-DD module optical, njll.
Thatha i-QSFP28 njengesibonelo, esebenza ku-4 × 25GE port yokufinyelela. I-QSFP28 ingasetshenziswa ukuthuthukisa kusuka ku-25G kuya ku-100G ngaphandle kwe-40G, okwenza kube lula kakhulu ubunzima bekhebula nokunciphisa izindleko.
QSFP/QSFP+/QSFP28/QSFP28-DD
I-QSFP-DD, eyasungulwa ngo-March 2016, ibhekisela “ku-Double Density”. Engeza umugqa wamashaneli eziteshini ezi-4 ze-QSFP futhi uziguqule zibe iziteshi eziyisi-8.
Ingahambisana nohlelo lwe-QSFP. Imojula yokuqala ye-QSFP28 isengasetshenziswa, vele ufake enye imojuli. Inombolo yeminwe yegolide ye-OSFP-DD iphindwe kabili kune-QSFP28.
I-QSFP-DD ngayinye isebenzisa ifomethi yesignali engu-25Gbps NRZ noma engu-50Gbps PAM4. Nge-PAM4, ingakwazi ukusekela kufika ku-400Gbps.
I-OSFP
I-OSFP, i-Octal Small Form Factor Pluggable, “O” imele ukuthi “octal”, eyethulwe ngokusemthethweni ngoNovemba 2016.
Iklanyelwe ukusebenzisa iziteshi zikagesi ezingu-8 ukuze ibone i-400GbE (8 * 56GbE, kodwa isignali ye-56GbE yakhiwe nge-laser engu-25G DML ngaphansi kwe-modulation ye-PAM4), futhi ubukhulu bayo bukhulu kancane kune-QSFP-DD. Injini ye-optical kanye ne-transceiver enamanzi aphakeme kakhulu inokusebenza okungcono kancane kokukhipha ukushisa.
CFP/CFP2/CFP4/CFP8
I-Centum gigabits Form I-plugable, i-dense wavelength division optical communication module. Izinga lokudlulisela lingafinyelela ku-100-400Gbpso
I-CFP yakhelwe ngesisekelo se-SFP interface, enosayizi omkhulu futhi esekela ukudluliswa kwedatha ye-100Gbps. I-CFP ingasekela isignali eyodwa ye-100G kanye nesignali eyodwa noma ngaphezulu ye-40G.
Umehluko phakathi kwe-CFP, i-CFP2 ne-CFP4 yivolumu. Umthamo we-CFP2 uyingxenye ye-CFP, kanti i-CFP4 iyingxenye eyodwa kwezine yaleyo ye-CFP. I-CFP8 iyifomu lokupakisha elihlongozwe ngokukhethekile i-400G, futhi ubukhulu bayo bulingana ne-CFP2. Sekela amanani wesiteshi angu-25Gbps no-50Gbps, futhi uqaphele izinga lemojuli engu-400Gbps ngokusebenzisa isixhumi esibonakalayo sikagesi esingu-16x25G noma esingu-8×50.
