Module ya DWDM optique ni iki?

Ikoranabuhanga rya Dense Wavelength Division Multiplexing (DWDM) rishobora gukoreshwa mu bice bitandukanye by'imiyoboro y'itumanaho, harimo imiyoboro y'intambwe ndende, imiyoboro y'uturere tw'umujyi (MAN), imiyoboro yo kugera ku baturage, n'imiyoboro y'uturere tw'umujyi (LAN).

Muri izi porogaramu, cyane cyane MAN, modules ntoya zishobora gucomekaho (SFP) n'izindi modules za optique zikunze gushyirwa muri modules zifite ubucucike bwinshi. Niyo mpamvu abantu bategerezanyije amatsiko cyane transceivers za DWDM optique. Iyi nyigisho izakubwira incamake ya modules za DWDM optique, kandi ikumenyeshe ibisubizo bya module za Beiyi Fibercom (WWW.F-TONE.COM).

Module ya DWDM optique ni iki?

Nk'uko izina ryayo ribitubwira, module ya DWDM optical ni module ya optique ihuza ikoranabuhanga rya DWDM. Module ya DWDM optique ikoresha uburebure butandukanye bw'umuraba kugira ngo ivange ibimenyetso byinshi bya optique mu fibre imwe ya optique, kandi iki gikorwa ntigikoresha ingufu iyo ari yo yose. Izi module za optique zagenewe kohereza ubutumwa bufite ubushobozi bwo hejuru, intera ndende, igipimo gishobora kugera kuri 10GBPS, kandi intera yo gukora ishobora kugera kuri 120KM. Muri icyo gihe, module ya optique ya DWDM yakozwe hakurikijwe amahame ya Multilateral Agreement (MSA) kugira ngo habeho uburyo bwinshi bwo guhuza ibikoresho bya network. Module za 10G DWDM optique zishyigikira ESCON, ATM, Fiber Channel na 10 Gigabit Ethernet (10GBE) kuri buri port. Module za DWDM optique ku isoko zikunze kuba zirimo: DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2 na DWDM XENPAK optique modules, nibindi.

Imikorere n'amahame ngiro ya module ya optique ya DWDM

Imikorere y'ibanze n'ihame ry'imikorere rya module ya DWDM optical ni kimwe n'izindi module za optique, zihindura ibimenyetso by'amashanyarazi mo ibimenyetso bya optique, hanyuma zigahindura ibimenyetso bya optique mo ibimenyetso by'amashanyarazi. Ariko, module ya optique ya DWDM yagenewe porogaramu za DWDM, kandi ni ngombwa kuvuga ko ifite imiterere n'imikorere yayo. Ugereranyije na module ya optique ya coarse wavelength division multiplexing (CWDM), module ya optique ya DWDM yagenewe fibre imwe, kandi nk'uko byasobanuwe neza na ITU-T, iri mu rugero rwa DWDM hagati ya 1528.38 na 1563.86NM (channel 17 kugeza channel 61). ikora hagati y'uburebure bw'uburebure. Ikoreshwa mu gushyira mu bikoresho bya DWDM network byo kugera mu mijyi no ku muyoboro w'ibanze. Iza hamwe na SFP 20-pin connector kugira ngo ikore neza. Igice cyayo cyo kohereza gikoresha laser ya DWDM multiple quantum well DFB, ikaba ari laser ikurikiza urwego rwa 1 hakurikijwe amahame mpuzamahanga y'umutekano IEC-60825. Byongeye kandi, module za DWDM optique zitangwa n'abatanga serivisi benshi zujuje ibipimo ngenderwaho bya SFF-8472 MSA. Udushya dushya muri sisitemu zo kohereza za DWDM turimo module za optique zishobora gucomeka, zishobora gukoreshwa ku miyoboro 40 cyangwa 80. Ibi bigabanya cyane gukenera module zitandukanye zishobora gucomeka mu gihe uburebure bwose bw'umurambararo bushobora gukoreshwa gusa hakoreshejwe ibikoresho bike bishobora gucomeka hano na hariya.

Ishyirwa mu byiciro rya module za DWDM optique

Ubusanzwe, iyo tuvuga module za DWDM optical, tuvuga module za Gigabit cyangwa 10 Gigabit DWDM optical. Dukurikije ubwoko butandukanye bwo gupakira, module za DWDM optical zishobora kugabanywamo ubwoko butanu. Izo module ni izi: DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2, na DWDM XENPAK optical modules.

SFP za DWDM

Iyi module ihuye neza n’ibipimo ngenderwaho bya Ethernet IEEE 802.3AE kandi ni nziza cyane ku itumanaho rya Gigabit Ethernet 10 (rack-to-rack, client interconnect). Iyi module ya transceiver igizwe n’ibi bikurikira: transmitter ifite laser ya DWDM EML ikonje, receiver ifite photodiode yo mu bwoko bwa PIN, interface ya XAUI, encoder/decoder integrated hamwe na multiplexer/demultiplexer.

DWDM XENPAK

DWDM XENPAK optique module ni module ya mbere ya Gigabit Ethernet 10 ishyigikira DWDM. DWDM ni ikoranabuhanga ryo kohereza amakuru rinyuze mu nzira nyinshi kuri fibre imwe y'urumuri. Hakoreshejwe amplifier ya optique EDFA, module ya DWDM XENPAK optique ishobora gushyigikira kohereza amakuru y'imiyoboro 32 ifite intera igera kuri 200KM. Sisitemu ya Ethernet ya Gigabit 10 ishingiye ku ikoranabuhanga rya DWDM ikorwa hatabayeho igikoresho cyo hanze cyihariye - transceiver y'urumuri (yo guhindura uburebure bw'umurambararo kuva (urugero: 1310NM) kugera kuri DWDM optique) -.

Gukoresha module ya DWDM optique

Module za DWDM optique zikunze gukoreshwa muri sisitemu za DWDM. Nubwo ikiguzi cya module za DWDM optique kiri hejuru kurusha iza module za CWDM optique, DWDM ikoreshwa cyane muri MAN cyangwa LAN mu bijyanye no kwiyongera kw'ibikenewe. Ubwoko butandukanye bwa module za DWDM optique zifite porogaramu zitandukanye. DWDM SFP ishobora gukoreshwa muri network ya DWDM yazamuwe, Fiber Channel, topology ya network ya OADM idahinduka kandi ishobora kuvugurura, Fast Ethernet, Gigabit Ethernet n'izindi sisitemu zo kohereza optique. DWDM SFP+ ihuye n'ibipimo ngenderwaho bya 10GBASE-ZR/ZW kandi ishobora gukoreshwa ku nsinga za optique za 10G. DWDM XFP ikoreshwa mu buryo busanzwe iyo yujuje ibisabwa bitandukanye birimo: 10GBASE-ER/EW Ethernet, 1200-SM-LL-L 10G Fiber Channel, SONET OC-192 IR-2, SDH STM S-64.2B, SONET OC-192 IR-3, SDH STM S-64.3B na ITU-T G.709. Izindi ngero nka DWDM X2 na DWDM XENPAK zikoreshwa mu buryo nk'ubwo. Byongeye kandi, izi module za DWDM optique zishobora no gukoreshwa ku miyoboro ya switch-to-switch, porogaramu za switching backplane, na router/server interfaces, nibindi.

HUANET itanga ubwoko bwose bw'ibicuruzwa bya sisitemu za DWDM. Ishami ryacu ry'ubushakashatsi n'iterambere n'itsinda rya tekiniki, binyuze mu ikoranabuhanga rigezweho n'ubushobozi bukomeye bwo guhanga udushya, bakoze ibice byiza cyane bya optique mu rwego rwabo kuri sisitemu za DWDM. Umurongo w'ibicuruzwa bya transceiver ya optique ya DWDM ni umwe mu mirongo yacu igurishwa cyane. Dutanga module za optique za DWDM zifite ubwoko butandukanye bw'ibipaki, intera itandukanye yo kohereza no gutwara ibintu bitandukanye. Byongeye kandi, module za optique za HUANET za DWDM zihuye n'izindi sosiyete, nka CISCO, FINISAR, HP, JDSU, nibindi, kandi zikwiriye imiyoboro ya OEM isaba imiterere ijyanye n'imikorere. Amaherezo, OEM na ODM zombi zirahari.
