Kodi CWDM Optical module ndi chiyani

Ndi chitukuko cha optical communication, optical communication zigawo zikukulanso mofulumira.Monga chimodzi mwa zigawo za kulankhulana kwa kuwala, gawo la kuwala limagwira ntchito ya kutembenuka kwa photoelectric.Pali mitundu yambiri ya ma modules optical, omwe amadziwika kwambiri ndi QSFP28 optical module, SFP optical module, QSFP + optical module, CXP optical module, CWDM optical module, DWDM optical module ndi zina zotero.Module iliyonse ya optical imakhala ndi zochitika ndi ntchito zosiyanasiyana.Tsopano ndikudziwitsani CWDM Optical module.

CWDM ndi ukadaulo wotsika mtengo wa WDM wofikira pa netiweki ya metropolitan area.Mfundo yake, CWDM ndiyo kugwiritsa ntchito multiplexer optical multiplex optical sign of different wavelengths mu fiber single kuwala kwa kufalitsa.chizindikiro, gwirizanitsani ndi zipangizo zolandirira zofanana.

Ndiye, CWDM Optical module ndi chiyani?

CWDM optical module ndi optical module pogwiritsa ntchito teknoloji ya CWDM, yomwe imagwiritsidwa ntchito kuzindikira kugwirizana pakati pa zipangizo zamakono zomwe zilipo ndi CWDM multiplexer / demultiplexer.Mukagwiritsidwa ntchito ndi CWDM multiplexers / demultiplexers, CWDM optical modules ikhoza kuonjezera mphamvu ya maukonde mwa kutumiza ma data angapo omwe ali ndi mawonekedwe osiyana optical wavelengths (1270nm mpaka 1610nm) pamtundu umodzi womwewo.

Ubwino wa CWDM ndi chiyani?

Ubwino wofunikira wa CWDM ndi mtengo wotsika wa zida.Kuonjezera apo, ubwino wina wa CWDM ndikuti ukhoza kuchepetsa mtengo wogwira ntchito pa intaneti.Chifukwa chazing'ono, kugwiritsa ntchito mphamvu zochepa, kukonza kosavuta komanso magetsi osavuta a zida za CWDM, magetsi a 220V AC angagwiritsidwe ntchito.Chifukwa cha kuchuluka kwa mafunde ang'onoang'ono, mphamvu zosunga zobwezeretsera za bolodi ndizochepa.Zida za CWDM zomwe zimagwiritsa ntchito mafunde a 8 zilibe zofunikira zapadera pazitsulo za optical, ndipo G.652, G.653, ndi G.655 optical fibers zingagwiritsidwe ntchito, ndipo zingwe zowunikira zomwe zilipo zingagwiritsidwe ntchito.Dongosolo la CWDM limatha kukulitsa kwambiri mphamvu yotumizira ulusi wamagetsi ndikuwongolera kagwiritsidwe ntchito kazinthu zamagetsi.Kumanga kwa ma netiweki a metropolitan area kumakumana ndi vuto linalake la kusowa kwa zinthu zopangira kuwala kapena kukwera mtengo kwa ulusi wopangidwa ndi lease.Pakalipano, mawonekedwe a coarse wavelength division multiplexing angapereke ma 8 optical channels, ndipo amatha kufika ku 18 Optical channels molingana ndi ndondomeko ya G.694.2 ya ITU-T.

Ubwino wina wa CWDM ndi kukula kwake kochepa komanso kugwiritsa ntchito mphamvu zochepa.Ma lasers mu dongosolo la CWDM safuna mafiriji a semiconductor ndi ntchito zowongolera kutentha, kotero kuti mphamvu yogwiritsira ntchito mphamvu ikhoza kuchepetsedwa kwambiri.Mwachitsanzo, laser iliyonse mu dongosolo la DWDM imadya pafupifupi 4W ya mphamvu, pamene laser CWDM popanda ozizira imangodya 0.5W ya mphamvu.Ma module osavuta a laser mu dongosolo la CWDM amachepetsa kuchuluka kwa gawo lophatikizika la optical transceiver, komanso kuphweka kwa zida zopangira zida kumachepetsanso kuchuluka kwa zida ndikusunga malo mu chipinda cha zida.

Kodi mitundu ya ma module a CWDM Optical ndi ati?

(1) CWDM SFP Optical module

CWDMSFP optical module ndi optical module yomwe imagwirizanitsa teknoloji ya CWDM.Mofanana ndi SFP yachikhalidwe, CWDM SFP optical module ndi chipangizo chothandizira / chotulutsa chotentha chomwe chimalowetsedwa mu doko la SFP la switch kapena rauta, ndipo imagwirizanitsidwa ndi optical fiber network kudzera pa doko ili.Ndi njira yolumikizira netiweki yachuma komanso yothandiza kwambiri yomwe imagwiritsidwa ntchito kwambiri pamanetiweki monga Gigabit Ethernet ndi Fiber Channel (FC) m'makampasi, malo opangira data, ndi ma network amderali.

(2) CWDM GBIC (Gigabit Interface Converter)

GBIC ndi chipangizo cholowetsa / chotulutsa chotentha chomwe chimalumikiza doko la Gigabit Ethernet kapena slot kuti mumalize kulumikizana ndi netiweki.GBIC ndi mulingo wa transceiver, womwe nthawi zambiri umagwiritsidwa ntchito limodzi ndi Gigabit Ethernet ndi Fiber Channel, ndipo umagwiritsidwa ntchito makamaka mu ma switch a Gigabit Ethernet ndi ma router.Kusintha kosavuta kuchokera ku gawo lokhazikika la LH, pogwiritsa ntchito ma lasers a DFB okhala ndi mafunde enieni, amalimbikitsa chitukuko cha CWDM GBIC optical modules ndi DWDM GBIC optical modules.Ma module a GBIC optical amagwiritsidwa ntchito pa Gigabit Ethernet optical fiber transmission, koma amakhalanso nawo nthawi zina, monga kuchepetsa liwiro la fiber network, kuthamanga ndi maulendo angapo opatsirana pozungulira 2.5Gbps.

GBIC Optical module ndiyotentha kwambiri.Mbaliyi, yophatikizidwa ndi mapangidwe opangidwa mwaluso a nyumbayo, imapangitsa kuti zitheke kusintha kuchokera ku mtundu wina wa mawonekedwe akunja kupita ku mtundu wina wolumikizira mwa kungoyika gawo la GBIC optical module.Nthawi zambiri, GBIC imagwiritsidwa ntchito molumikizana ndi zolumikizira za SC.

(3) CWDM X2

CWDM X2 optical module, yogwiritsidwa ntchito pa CWDM optical data communication, monga 10G Ethernet ndi 10G Fiber Channel ntchito.Kutalika kwa mawonekedwe a CWDMX2 optical module kungakhale kuchokera ku 1270nm mpaka 1610nm.CWDMX2 Optical module imagwirizana ndi muyezo wa MSA.Imathandizira kufalikira kwa mtunda wa makilomita 80 ndipo imalumikizidwa ndi chingwe cha duplex SC single-mode fiber patch.

(4) CWDM XFP Optical module

Kusiyana kwakukulu pakati pa CWDM XFP optical module ndi CWDM SFP + optical module ndi maonekedwe.CWDM XFP optical module ndi yaikulu kuposa CWDM SFP + optical module.Protocol ya CWDM XFP optical module ndi XFP MSA protocol, pamene CWDM SFP + optical module ikugwirizana ndi IEEE802.3ae , SFF-8431, SFF-8432 protocols.

(5) CWDM SFF (yaing'ono)

SFF ndiye gawo loyamba lazamalonda laling'ono la kuwala, lomwe limangotenga theka la malo amtundu wamba wa SC.CWDM SFF optical module yawonjezera ntchito kuchokera ku 100M mpaka 2.5G.Palibe opanga ambiri omwe amapanga ma SFF optical modules, ndipo tsopano msika uli makamaka SFP Optical modules.

(6) CWDM SFP + Optical module

The CWDM SFP + optical module multiplexes optical signals of different wavelengths kudzera kunja kwa wavelength division multiplexer ndikuwatumiza kudzera mu fiber imodzi ya kuwala, potero kupulumutsa optical fiber resources.Panthawi imodzimodziyo, mapeto olandila amafunika kugwiritsa ntchito ma wave division multiplexer kuti awononge chizindikiro chovuta cha kuwala.CWDM SFP + Optical module imagawidwa m'magulu 18, kuchokera ku 1270nm mpaka 16.

10nm, ndi nthawi ya 20nm pakati pa magulu awiri aliwonse.
