Imodyuli ye-optical yakhiwe ngamadivaysi e-optoelectronic, ama-circuits asebenzayo kanye ne-optical interfaces.Idivayisi ye-optoelectronic ihlanganisa izingxenye zokudlulisela nokwamukela.Amamojula we-Optical asetshenziswa kakhulu ekuxhumaneni kwe-optical, izikhungo zedatha nezinye izindawo.Ngakho-ke, iyini ngempela imojuli ye-optical?Kuyini ukusetshenziswa kwamamojula we-optical?Okulandelayo, asilandele umhleli we-Feichang Technology ukuze ufunde kabanzi ngakho!
Kalula nje, indima ye-optical module ukuguqulwa kwe-photoelectric.Isiphetho sokudlulisa siguqula isignali kagesi ibe isignali yokubona.Ngemva kokudlulisela nge-fiber optical, isiphetho sokwamukela siguqula isignali ye-optical ibe isignali kagesi.
Ngaphezu kwalokho, amamojula optical ahlukaniswa ngokuya emaphaketheni futhi angahlukaniswa abe:
1. I-XFP optical module iyi-hot-swappable optical transceiver ezimele ngaphandle kwephrothokholi yokuxhumana.Isetshenziselwa i-10G bps Ethernet, i-SONET/SDH, kanye nesiteshi se-fiber optical.
2. Amamojula we-SFP optical, amamojula amancane amukelayo nama-light emitting (SFP), asetshenziswa kabanzi okwamanje.
3. Amamojula we-GigacBiDi ochungechunge olulodwa lwe-fiber bidirectional optical asebenzisa ubuchwepheshe be-WDM ukuze abone ukudluliswa kwefayibha kolwazi lwezindlela ezimbili (i-point-to-point transmission. Ikakhulukazi, izinsiza ze-fiber azanele, futhi i-fiber eyodwa iyadingeka ukuze kudluliselwe amasignali wezindlela ezimbili. ).I-GigacBiDi ihlanganisa i-SFP single fibre bidirectional (BiDi), i-GBIC single fibre bidirectional (BiDi), SFP+ single fibre bidirectional (BiDi), XFP single fibre bidirectional (BiDi), SFF single fibre bidirectional (BiDi) njalonjalo.
4. I-module ye-electrical port, i-RJ45 kagesi ye-port module encane exhunyiwe, eyaziwa nangokuthi i-module kagesi noma i-module port kagesi.
5. Amamojula we-SFF optical ahlukaniswe abe yi-2×5, 2×10, njll ngokusho kwezikhonkwane zawo.
6. GBIC optical module, Gigabit Ethernet interface converter (GBIC) module.
7. I-PON optical module, i-passive optical network PON (A-PON, G-PON, GE-PON) module optical.
8. I-40Gbs imojuli ye-optical enesivinini esikhulu.
9. Imojula yokudlulisa ye-SDH (OC3, OC12).
10. Amamojula wesitoreji, njenge-4G, 8G, njll.
Ngakho-ke, bheka lapha, yini i-SFP optical module?Ingabe uyayazi impendulo yalo mbuzo?Ngakho-ke, uyini umsebenzi we-SFP optical module?
I-SFP optical module iyimojula yephakheji encane eshintshwayo eshintshwayo kuphakheji ye-SFP.Isilinganiso samanje se-gao singafinyelela ku-10.3G, futhi isikhombimsebenzisi yi-LC.I-SFP optical module ikakhulukazi yakhiwe ilaser.Ngaphezu kwalokho, i-SFP optical module iqukethe: i-laser: kuhlanganise ne-fa transmitter TOSA kanye ne-ROSA yokwamukela;ibhodi lesifunda IC;izesekeli zangaphandle zifaka: igobolondo, isisekelo, i-PCBA, indandatho yokudonsa, ibhande, ucezu lokuvula, ipulaki yerabha.Ngaphezu kwalokho, amamojula we-SFP optical angahlukaniswa ngokuya ngesivinini, ubude be-wavelength, kanye nemodi.
Izinga ngokwezigaba
Ngokwejubane, kukhona i-155M/622M/1.25G/2.125G/4.25G/8G/10G, 155M kanye ne-1.25G esetshenziswa kakhulu emakethe.Ubuchwepheshe be-10G buvuthwa kancane kancane, futhi isidingo siyanda.ukuthuthukiswa kwe.
Ukuhlukaniswa kwe-wavelength
Ngokwe-wavelength, kukhona i-850nm/1310nm/1550nm/1490nm/1530nm/1610nm.I-wavelength ingu-850nm ye-multimode ye-SFP, ibanga lokudlulisela lingaphansi kwe-2KM, futhi ubude be-wavelength ngu-1310/1550nm ngemodi eyodwa, futhi ibanga lokudlulisela lingaphezulu kwe-2KM.Uma kuqhathaniswa, lokhu Intengo yamaza amaza amathathu ishibhile kunamanye amathathu.
Kulula ukudida imojuli engenalutho uma ingekho i-logo.Ngokuvamile, abakhiqizi bazohlukanisa umbala wendandatho yokudonsa.Isibonelo, indandatho yokudonsa emnyama inemodi eminingi futhi ubude begagasi bungu-850nm;okuluhlaza okwesibhakabhaka yimojula enobude begagasi obungu-1310nm;**ubude begagasi ngu-1550nm Imojula;okunsomi kuyimojula enobude begagasi obungu-1490nm, njll.
Ukuhlukaniswa kwephethini
SFP optical module multimode
Cishe wonke ama-multimode optical fibers angama-50/125um noma angu-62.5/125um ngosayizi, futhi umkhawulokudonsa (inani lolwazi oludluliswa yi-optical fiber) ngokuvamile lingu-200MHz ukuya ku-2GHz.Ama-transceiver optical amamodi amaningi angadlulisa amakhilomitha afinyelela ku-5 ngokusebenzisa imicu ye-multi-mode optical.Sebenzisa ama-diode akhipha ukukhanya noma amalaser njengemithombo yokukhanya.Umbala wendandatho yokudonsa noma umzimba wangaphandle umnyama.
Imodi eyodwa ye-SFP optical module
Usayizi wefiber yemodi eyodwa ngu-9-10/125?m, futhi uma uqhathaniswa ne-multi-mode fiber, unomkhawulokudonsa ongenamkhawulo nezici zokulahlekelwa eziphansi.I-transceiver yemodi eyodwa ye-optical isetshenziswa kakhulu ekudluliseleni ibanga elide, kwesinye isikhathi kufika kumakhilomitha ayi-150 kuye kwangama-200.Sebenzisa i-LD noma i-LED enomugqa we-spectral omncane njengomthombo wokukhanya.
