Yini i-DWDM optical module?

Ubuchwepheshe beDense Wavelength Division Multiplexing (DWDM) bungasetshenziswa ezindaweni ezihlukene zamanethiwekhi okuxhumana, okuhlanganisa amanethiwekhi omgogodla webanga elide, amanethiwekhi endawo yedolobha elikhulu (MAN), amanethiwekhi okufinyelela okuhlala, kanye namanethiwekhi wendawo (LAN).

Kulezi zinhlelo zokusebenza, ikakhulukazi ama-MAN, i-form-factor pluggable encane (i-SFP) nezinye izinhlobo zamamojula optical ngokuvamile zifakwe ku-high-density form factor.Yingakho abantu bebheke ngabomvu ama-transceiver optical e-DWDM kakhulu.Lesi sifundo sizokutshela mayelana nokubukezwa kwamamojula we-DWDM optical, futhi sikwethule ku-Beiyi Fibercom (WWW.F-TONE.COM) DWDM optical module solutions.

Yini i-DWDM optical module?

Njengoba igama layo lisitshela, i-DWDM optical module iyimojula ye-optical ehlanganisa ubuchwepheshe be-DWDM.Imodyuli ye-DWDM optical isebenzisa ubude obuhlukahlukene bokuphindaphinda amasignali amaningi optical ibe yi-fiber eyodwa, futhi lokhu kusebenza akudli noma yimaphi amandla.Lawa mamojula optical aklanyelwe amandla aphezulu, ukudluliselwa kwebanga elide, izinga lingafinyelela ku-10GBPS, futhi ibanga lokusebenza lingafinyelela ku-120KM.Ngesikhathi esifanayo, i-DWDM optical module iklanyelwe ngokuvumelana neSivumelwano se-Multilateral Agreement (MSA) ukuze kuqinisekiswe ukuhambisana okubanzi kwemishini yenethiwekhi.Amamojula we-10G DWDM optical asekela i-ESCON, i-ATM, i-Fiber Channel kanye ne-10 Gigabit Ethernet (10GBE) echwebeni ngalinye.Amamojula we-DWDM optical emakethe ngokuvamile ahlanganisa: DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2 kanye ne-DWDM XENPAK optical modules, njll.

Umsebenzi kanye nesimiso sokusebenza se-DWDM optical module

Umsebenzi oyisisekelo kanye nesimiso sokusebenza se-DWDM optical module sifana namanye amamojula optical, aguqula amasignali kagesi abe amasignali optical, bese eguqula amasignali optical abe amasignali kagesi.Kodwa-ke, i-DWDM optical module yakhelwe izinhlelo zokusebenza ze-DWDM, futhi kufanelekile ukusho ukuthi inezici zayo nemisebenzi yayo.Uma kuqhathaniswa ne-coarse wavelength division multiplexing (CWDM) optical module, imojula ye-DWDM optical yakhelwe i-fiber yemodi eyodwa, futhi njengoba kucaciswe ngokucacile yi-ITU-T, isebangeni le-DWDM elilinganiselwe lika-1528.38 kuya ku-1563.86NM (isiteshi 17 kuya ku- isiteshi 61).sebenza phakathi kwama-wavelengths.Isetshenziselwa ukusabalalisa kumishini yenethiwekhi ye-DWDM yokufinyelela emadolobheni kanye nenethiwekhi eyinhloko.Iza nesixhumi se-SFP 20-pin sokusebenza okushintshwayo okushisayo.Isigaba sayo sokudlulisela sisebenzisa i-DWDM multiple quantum well DFB laser, okuyilaser ethobelayo Yekilasi 1 ngokwezinga lokuphepha lamazwe ngamazwe le-IEC-60825.Ngaphezu kwalokho, amamojula e-DWDM optical avela kubahlinzeki abaningi ahambisana nezinga le-SFF-8472 MSA.Izindlela ezintsha zakamuva ezinhlelweni zokudlulisa i-DWDM zihlanganisa amamojula optical axhumekayo, akwazi ukusebenza eziteshini ezingama-40 noma ezingama-80.Le mpumelelo inciphisa kakhulu isidingo samamojula ahlukene axhumekeka kalula lapho ububanzi obugcwele bamaza obude bungasetshenziswa kuphela ngamadivaysi ambalwa axhumeka lapha nalaphaya.

Ukuhlukaniswa kwamamojula we-DWDM optical

Ngokuvamile, lapho sibhekisela kumamojula optical e-DWDM, sibhekisela ku-Gigabit noma i-10 Gigabit DWDM optical modules.Ngokusho kwamafomu okupakisha ahlukene, amamojula we-DWDM optical angahlukaniswa ikakhulukazi ngezinhlobo ezinhlanu.Lawa: I-DWDM SFP, i-DWDM SFP+, i-DWDM XFP, i-DWDM X2, ne-DWDM XENPAK optical modules.
