Imodyuli ye-optical yenziwe ngezixhobo ze-optoelectronic, iisekethe ezisebenzayo kunye ne-optical interfaces.Isixhobo se-optoelectronic sibandakanya ukuhambisa kunye nokufumana iinxalenye.Iimodyuli ze-Optical zisetyenziswa ikakhulu kunxibelelwano lwe-optical, amaziko edatha kunye nezinye iindawo.Ke, yintoni kanye kanye imodyuli ye-optical?Yintoni ukusetyenziswa kweemodyuli zamehlo?Okulandelayo, masilandele umhleli weFeichang Technology ukufunda ngakumbi ngayo!
Ukubeka nje, indima yemodyuli ye-optical kukuguqulwa kwe-photoelectric.Isiphelo sokudlulisa siguqula umqondiso wombane ube ngumqondiso we-optical.Emva kokudluliselwa nge-fiber optical, isiphelo sokufumana siguqula isignali ye-optical ibe ngumqondiso wombane.
Ukongeza, iimodyuli ze-optical zihlelwa ngokuhambelana nokupakishwa kwaye zinokwahlulwa zibe:
1. Imodyuli ye-XFP ye-optical i-transceiver optical eshushu-swappable ezimeleyo kwi-protocol yonxibelelwano.Isetyenziselwa i-10G bps Ethernet, i-SONET / SDH, kunye nesiteshi se-fiber optical.
2. Iimodyuli ze-SFP optical, iimodyuli ezincinci zokwamkela kunye ne-light emitting modules (SFP), okwangoku zisetyenziswa ngokubanzi.
3. Iimodyuli ze-GigacBiDi i-single-fiber bidirectional optical modules isebenzisa iteknoloji ye-WDM ukuqaphela ukuhanjiswa kwefiber yolwazi lweendlela ezimbini (ukuhanjiswa kwe-point-to-point. Ngokukodwa, izibonelelo zefiber azanelanga, kwaye enye i-fiber iyadingeka ukuhambisa iimpawu ezimbini. ).I-GigacBiDi iquka i-SFP enye i-fiber bidirectional (BiDi), i-GBIC enye i-fiber bidirectional (BiDi), i-SFP + enye i-fiber bidirectional (BiDi), i-XFP enye i-fiber bidirectional (BiDi), i-SFF enye i-fiber bidirectional (BiDi) njalo njalo.
4. Imodyuli ye-port yombane, i-RJ45 yombane i-port encinci ye-pluggable module, eyaziwa ngokuba yimodyuli yombane okanye imodyuli yombane.
5. Iimodyuli ze-SFF ze-optical zihlukaniswe zibe yi-2 × 5, 2 × 10, njl njl ngokwezikhonkwane zazo.
6. Imodyuli ye-GBIC optical, imodyuli ye-Gigabit Ethernet interface converter (GBIC).
7. I-PON imodyuli ye-optical, i-passive network optical network PON (A-PON, G-PON, GE-PON) imodyuli ye-optical.
8. I-40Gbs imodyuli ye-optical high-speed.
9. Imodyuli yokudluliselwa kwe-SDH (OC3, OC12).
10. Iimodyuli zokugcina, ezifana ne-4G, 8G, njl.
Ke, bona apha, yintoni imodyuli ye-SFP yokubona?Ngaba uyayazi impendulo yalo mbuzo?Ke, yintoni umsebenzi wemodyuli ye-SFP optical?
Imodyuli ye-SFP ebonakalayo yimodyuli encinci yephakheji eshushu-swappable kwiphakheji ye-SFP.Izinga le-gao langoku linokufikelela kwi-10.3G, kwaye i-interface yi-LC.Imodyuli ye-SFP ye-optical ikakhulu yenziwe ngelaser.Ukongeza, imodyuli ye-SFP ye-optical iqukethe: i-laser: kubandakanywa ne-fa transmitter TOSA kunye ne-ROSA yomamkeli;ibhodi yesekethe IC;izincedisi zangaphandle ziquka: iqokobhe, isiseko, PCBA, tsala umsesane, ikhonkco, iqhekeza lokuvula, iplagi yerabha.Ukongeza, iimodyuli ze-SFP ze-optical zingahlelwa ngokwesantya, ubude be-wavelength, kunye nemowudi.
Ukuhlelwa kwereyithi
Ngokwesantya, kukho i-155M/622M/1.25G/2.125G/4.25G/8G/10G, 155M kunye ne-1.25G zisetyenziswa ngakumbi kwiimarike.I-teknoloji ye-10G ikhula ngokuthe ngcembe, kwaye imfuno iyanda.Uphuhliso lwe.
Ukuhlelwa kweWavelength
Ngokobude be-wavelength, kukho i-850nm/1310nm/1550nm/1490nm/1530nm/1610nm.Ubude be-wavelength yi-850nm ye-multimode ye-SFP, umgama wokuhambisa ungaphantsi kwe-2KM, kunye ne-wavelength yi-1310 / 1550nm kwimodi enye, kwaye umgama wokuhambisa ungaphezulu kwe-2KM.Xa sithetha ngokuthelekisa, oku Ixabiso lobude obuthathu liphantsi kunezinye ezintathu.
Kulula ukubhidanisa imodyuli engenanto ukuba akukho logo.Ngokuqhelekileyo, abavelisi baya kuhlukanisa umbala wendandatho yokutsala.Umzekelo, umsesane wokutsalwa omnyama ukwimowudi eninzi kwaye ubude bobude bungama-850nm;iblue yimodyuli enobude be-1310nm;**ubude bobude yi-1550nm Imodyuli;purple yimodyuli enobude be-1490nm, njl.

Imodyuli yokubona ye-SFP ye-multimode
Phantse zonke i-multimode fibers optical fibers ziyi-50 / 125um okanye i-62.5 / 125um ngobukhulu, kunye ne-bandwidth (isixa solwazi oluhanjiswa yi-fiber optical) idla ngokuba yi-200MHz ukuya kwi-2GHz.I-Multi-mode transceivers optical transceivers inokudlulisa ukuya kwiikhilomitha ezi-5 ngokusebenzisa iifiber ze-optical mode ezininzi.Sebenzisa iidiode ezikhupha ukukhanya okanye iilaser njengemithombo yokukhanya.Umbala womsesane wokutsala okanye umzimba wangaphandle umnyama.
SFP imodyuli yokubona enye imodyuli
Ubungakanani befiber ye-mode eyodwa yi-9-10 / 125?m, kwaye xa kuthelekiswa nefiber ye-multi-mode, ine-bandwidth engenamkhawulo kunye neempawu zokulahlekelwa okuphantsi.I-single-mode optical transceiver isetyenziswa kakhulu kuthumelo lomgama omde, ngamanye amaxesha ukuya kuthi ga kwi-150 ukuya kwiikhilomitha ezingama-200.Sebenzisa i-LD okanye i-LED enomgca omncinci we-spectral njengomthombo wokukhanya.
