Iyini i-DWDM optical module?

Ubuchwepheshe be-Dense Wavelength Division Multiplexing (DWDM) bungasetshenziswa ezindaweni ezahlukene zamanethiwekhi okuxhumana, okuhlanganisa amanethiwekhi omgogodla amabanga amade, amanethiwekhi endawo yedolobha elikhulu (MAN), amanethiwekhi okufinyelela ezindaweni zokuhlala, kanye namanethiwekhi endawo yasendaweni (LAN).

Kulezi zinhlelo zokusebenza, ikakhulukazi ama-MAN, amamojula amancane afakwa ku-form-factor (SFP) kanye nezinye izinhlobo zamamojula e-optical avame ukufakwa kuma-form factors aphezulu. Yingakho abantu belangazelela ama-transceivers e-DWDM optical kangaka. Lesi sifundo sizokutshela ngokubuka konke kwamamojula e-DWDM optical, futhi sizokwethula kuzixazululo zemojula ye-Beiyi Fibercom (WWW.F-TONE.COM) DWDM optical.

Iyini i-DWDM optical module?

Njengoba igama layo lisitshela, i-DWDM optical module iyi-module ye-optical ehlanganisa ubuchwepheshe be-DWDM. I-DWDM optical module isebenzisa ama-wavelength ahlukene ukuhlanganisa izimpawu eziningi ze-optical zibe i-fiber eyodwa ye-optical, futhi lokhu kusebenza akusebenzisi amandla. Lawa mamojula e-optical aklanyelwe ukudlulisa okunamandla aphezulu, ibanga elide, izinga lingafinyelela ku-10GBPS, kanti ibanga lokusebenza lingafinyelela ku-120KM. Ngesikhathi esifanayo, i-DWDM optical module yaklanywa ngokwezinga le-Multilateral Agreement (MSA) ukuqinisekisa ukuhambisana okubanzi kwemishini yenethiwekhi. Amamojula e-10G DWDM optical asekela i-ESCON, i-ATM, i-Fiber Channel kanye ne-10 Gigabit Ethernet (10GBE) echwebeni ngalinye. Amamojula e-DWDM optical emakethe avame ukufaka: amamojula e-DWDM SFP, i-DWDM SFP+, i-DWDM XFP, i-DWDM X2 kanye ne-DWDM XENPAK optical, njll.

Umsebenzi kanye nomgomo wokusebenza we-DWDM optical module

Umsebenzi oyisisekelo kanye nomgomo wokusebenza we-DWDM optical module kufana namanye amamojula e-optical, aguqula amasignali kagesi abe amasignali e-optical, bese eguqula amasignali e-optical abe amasignali kagesi. Kodwa-ke, i-DWDM optical module yenzelwe izinhlelo zokusebenza ze-DWDM, futhi kufanelekile ukusho ukuthi inezici zayo nemisebenzi yayo. Uma kuqhathaniswa ne-coarse wavelength division multiplexing (CWDM) optical module, i-DWDM optical module yenzelwe i-fiber yemodi eyodwa, futhi njengoba kuchazwe ngokucacile yi-ITU-T, iku-DWDM nominal range kusukela ku-1528.38 kuya ku-1563.86NM (isiteshi 17 kuya kusiteshi 61). isebenza phakathi kwama-wavelength. Isetshenziselwa ukufaka imishini yenethiwekhi ye-DWDM yokufinyelela emadolobheni kanye nenethiwekhi eyinhloko. Iza nesixhumi se-SFP esingu-20-pin sokusebenza okushisayo okungashintshwa. Isigaba sayo sokudlulisa sisebenzisa i-DWDM multiple quantum well DFB laser, okuyi-Class 1 compliant laser ngokuya nge-international safety standard IEC-60825. Ngaphezu kwalokho, amamojula e-DWDM optical avela kubahlinzeki abaningi ahambisana nezinga le-SFF-8472 MSA. Izinto ezintsha zakamuva ezinhlelweni zokudlulisa ze-DWDM zifaka phakathi amamojula e-optical axhunywayo, aguquguqukayo akwazi ukusebenza eziteshini ezingama-40 noma ezingama-80. Le mpumelelo inciphisa kakhulu isidingo samamojula ahlukene axhunywayo lapho uhla oluphelele lwama-wavelength lungashintshwa kuphela ngamadivayisi ambalwa axhunywayo lapha nalaphaya.

Ukuhlukaniswa kwamamojula okukhanya e-DWDM

Ngokuvamile, uma sibhekisela kumamojula we-DWDM optical, sibhekisela kumamojula we-Gigabit noma we-10 Gigabit DWDM optical. Ngokwezinhlobo ezahlukene zokupakisha, amamojula we-DWDM optical angahlukaniswa kakhulu abe izinhlobo ezinhlanu.
