Kodi DWDM optical module ndi chiyani?

Ukadaulo wa Dense Wavelength Division Multiplexing (DWDM) ungagwiritsidwe ntchito m'magawo osiyanasiyana a maukonde olumikizirana, kuphatikiza maukonde akutali, maukonde a m'mizinda (MAN), maukonde ofikira anthu okhala m'nyumba, ndi maukonde a m'deralo (LAN).

Mu mapulogalamu awa, makamaka ma MAN, ma module ang'onoang'ono opangidwa ndi form-factor (SFP) ndi mitundu ina ya ma optical module nthawi zambiri amaikidwa mu ma high-density form factors. Ichi ndichifukwa chake anthu amayembekezera kwambiri ma DWDM optical transceivers. Phunziroli lidzakuuzani za chidule cha ma DWDM optical modules, ndikukuwonetsani njira zothetsera ma Beiyi Fibercom (WWW.F-TONE.COM) DWDM optical module.

Kodi DWDM optical module ndi chiyani?

Monga momwe dzina lake limanenera, DWDM optical module ndi optical module yomwe imaphatikiza ukadaulo wa DWDM. DWDM optical module imagwiritsa ntchito ma wavelength osiyanasiyana kuti ipangitse ma signal angapo a optical kukhala ulusi umodzi wa optical, ndipo ntchitoyi sigwiritsa ntchito mphamvu iliyonse. Ma optical module awa amapangidwira kutumiza kwamphamvu kwambiri, mtunda wautali, liwiro limatha kufika 10GBPS, ndipo mtunda wogwirira ntchito ukhoza kufika 120KM. Nthawi yomweyo, DWDM optical module imapangidwa motsatira muyezo wa Multilateral Agreement (MSA) kuti zitsimikizire kuti zida zambiri za netiweki zikugwirizana. Ma 10G DWDM optical modules amathandizira ESCON, ATM, Fiber Channel ndi 10 Gigabit Ethernet (10GBE) pa doko lililonse. Ma DWDM optical modules omwe ali pamsika nthawi zambiri amakhala ndi: DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2 ndi DWDM XENPAK optical modules, ndi zina zotero.

Ntchito ndi mfundo yogwirira ntchito ya DWDM optical module

Ntchito yoyambira ndi mfundo yogwirira ntchito ya DWDM optical module ndi yofanana ndi ma module ena a optical, omwe amasintha ma signal amagetsi kukhala ma signal a kuwala, kenako nkusintha ma signal a kuwala kukhala ma signal amagetsi. Komabe, DWDM optical module idapangidwira ntchito za DWDM, ndipo ndikofunikira kutchula kuti ili ndi makhalidwe ndi ntchito zake. Poyerekeza ndi coarse wavelength division multiplexing (CWDM) optical module, DWDM optical module idapangidwira ulusi wa single-mode, ndipo monga momwe ITU-T idafotokozera momveka bwino, ili mu DWDM nominal range ya 1528.38 mpaka 1563.86NM (njira 17 mpaka njira 61). imagwira ntchito pakati pa ma wavelength. Imagwiritsidwa ntchito kuyika zida za netiweki za DWDM za urban access ndi core network. Imabwera ndi cholumikizira cha SFP 20-pin cha ntchito yosinthika yotentha. Gawo lake lotumizira limagwiritsa ntchito DWDM multiple quantum well DFB laser, yomwe ndi Class 1 compliant laser malinga ndi muyezo wapadziko lonse wachitetezo wa IEC-60825. Kuphatikiza apo, ma module a DWDM optical ochokera kwa ogulitsa ambiri akutsatira muyezo wa SFF-8472 MSA. Zatsopano zomwe zapangidwa mu makina otumizira ma DWDM zimaphatikizapo ma module opangidwa ndi ma pluggable, osinthika omwe amatha kugwira ntchito pa njira 40 kapena 80. Kupambana kumeneku kumachepetsa kwambiri kufunikira kwa ma module osiyana opangidwa ndi ma pluggable pamene ma wavelength onse amatha kusinthidwa ndi zida zingapo zongopangidwa ndi ma pluggable apa ndi apo.

Kugawa ma module a DWDM optical

Kawirikawiri, tikamanena za ma DWDM optical modules, timanena za ma Gigabit kapena ma Gigabit 10 a DWDM optical modules. Malinga ndi mitundu yosiyanasiyana ya ma packaging, ma DWDM optical modules amatha kugawidwa m'mitundu isanu. Izi ndi: DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2, ndi DWDM XENPAK optical modules.

Ma DWDM SFP

Module ya DWDM SFP yowunikira imapereka ulalo wothamanga kwambiri wokhala ndi liwiro lotumizira chizindikiro cha 100 MBPS mpaka 2.5 GBPS. Module ya DWDM SFP yowunikira imagwirizana ndi zofunikira za muyezo wa IEEE802.3 Gigabit Ethernet ndi ANSI Fiber Channel, ndipo ndiyoyenera kulumikizidwa m'malo a Gigabit Ethernet ndi Fiber Channel.

DWDM SFP+

Ma module a DWDM SFP+ optical amapangidwira makamaka ogwiritsa ntchito ndi mabizinesi akuluakulu omwe amafunikira multiplexing, transmission ndi chitetezo mu point-to-point, add-drop multiplexing, ring, mesh and star network topology Deta yothamanga kwambiri, malo osungira, mawu ndi makanema, pogwiritsa ntchito njira yosinthika, yotsika mtengo komanso yotsika mtengo. DWDM imalola opereka chithandizo kukwaniritsa zofunikira za mautumiki ambiri ophatikizidwa pa protocol iliyonse ya subrate popanda kuyika ulusi wakuda wowonjezera. Chifukwa chake, DWDM SFP+ optical module ndiyo chisankho chabwino kwambiri pakugwiritsa ntchito bandwidth yayikulu kwambiri ya 10 Gigabit.

DWDM XFP

Chosinthira kuwala cha DWDM XFP chikugwirizana ndi zomwe XFP MSA ikunena panopa. Chimathandizira mapulogalamu a SONET/SDH, 10 Gigabit Ethernet ndi 10 Gigabit Fiber Channel.

DWDM X2

DWDM X2 optical module ndi module ya transceiver yothamanga kwambiri ya ma Gigabit 10 othamanga kwambiri. Module iyi ikugwirizana kwathunthu ndi muyezo wa Ethernet IEEE 802.3AE ndipo ndi yoyenera kugwiritsa ntchito ma Gigabit Ethernet data communications 10 (rack-to-rack, client interconnect). Module iyi ya transceiver ili ndi zigawo izi: transmitter yokhala ndi DWDM EML cooled laser, receiver yokhala ndi PIN type photodiode, XAUI connection interface, integrated encoder/decoder ndi multiplexer/demultiplexer device.

DWDM XENPAK

DWDM XENPAK optical module ndi gawo loyamba la 10 Gigabit Ethernet optical module lomwe limathandizira DWDM. DWDM ndi ukadaulo wotumizira magiya womwe umadutsa m'njira zingapo pa ulusi womwewo wa optical. Mothandizidwa ndi optical amplifier EDFA, DWDM XENPAK optical module imatha kuthandizira kutumiza deta ya njira 32 ndi mtunda wofika 200KM. Dongosolo la 10 Gigabit Ethernet lozikidwa pa ukadaulo wa DWDM limachitika popanda kufunikira chipangizo chakunja chodzipereka - chosinthira magiya (chosinthira magiya kuchokera (monga: 1310NM) kupita ku magiya a DWDM) -.

Kugwiritsa ntchito module ya DWDM optical

Ma module a DWDM optical nthawi zambiri amagwiritsidwa ntchito mu machitidwe a DWDM. Ngakhale mtengo wa ma module a DWDM optical ndi wokwera kuposa wa ma module a CWDM optical, DWDM imagwiritsidwa ntchito kwambiri mu MAN kapena LAN pankhani ya zofunikira zomwe zikuwonjezeka. Mitundu yosiyanasiyana ya ma DWDM optical module packaging ili ndi ntchito zosiyanasiyana. DWDM SFP ingagwiritsidwe ntchito mu netiweki ya DWDM yowonjezera, Fiber Channel, topology ya netiweki ya mphete ya OADM yokhazikika komanso yosinthika, Fast Ethernet, Gigabit Ethernet ndi machitidwe ena opatsira ma optical. DWDM SFP+ imagwirizana ndi muyezo wa 10GBASE-ZR/ZW ndipo ingagwiritsidwe ntchito pa zingwe za 10G optical. DWDM XFP nthawi zambiri imagwiritsidwa ntchito pamene ikugwirizana ndi miyezo yosiyanasiyana kuphatikizapo: 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 ndi miyezo ya ITU-T G.709. Mitundu ina monga DWDM X2 ndi DWDM XENPAK imagwiritsidwanso ntchito pazifukwa zofanana. Kuphatikiza apo, ma DWDM optical module awa angagwiritsidwenso ntchito pa ma switch-to-switch interfaces, switching backplane applications, ndi rauta/server interfaces, ndi zina zotero.

HUANET imapereka zinthu zosiyanasiyana za machitidwe a DWDM. Dipatimenti yathu ya R&D ndi gulu lathu laukadaulo, kudzera muukadaulo wapamwamba komanso luso lamphamvu lopanga zinthu zatsopano, apanga zida zabwino kwambiri zowunikira m'gulu lawo la machitidwe a DWDM. Mzere wazinthu zotumizira ma DWDM optical transceiver ndi umodzi mwa mizere yathu yogulitsa kwambiri. Timapereka ma module a DWDM optical okhala ndi mitundu yosiyanasiyana ya ma phukusi, mtunda wosiyana wa ma transmission ndi mitengo yosiyana ya ma transmission. Kuphatikiza apo, ma module a HUANET a DWDM optical amagwirizana ndi mitundu ina, monga CISCO, FINISAR, HP, JDSU, ndi zina zotero, ndipo ndi oyeneranso ma netiweki a OEM omwe amafunikira kufotokozera kogwirizana. Pomaliza, onse OEM ndi ODM akupezekanso.
