He aha ka DWDM optical module?

Hiki ke hoʻohana ʻia ka ʻenehana Dense Wavelength Division Multiplexing (DWDM) ma nā wahi like ʻole o nā ʻupena kamaʻilio, e like me nā pūnaewele iwi kuamoʻo lōʻihi, metropolitan area networks (MAN), wīwī hiki ke noho, a me nā pūnaewele ʻāpana kūloko (LAN).

I loko o kēia mau noi, ʻoi aku ka nui o nā MAN, nā mea liʻiliʻi-factor pluggable (SFP) a me nā ʻano modula optical ʻē aʻe i hoʻokomo pinepine ʻia i nā ʻano kumu kiʻekiʻe.ʻO kēia ke kumu e nānā nui ai nā kānaka i ka DWDM optical transceivers.Na kēia kumu aʻo e haʻi iā ʻoe e pili ana i ka ʻike o DWDM optical modules, a hoʻolauna iā ʻoe i Beiyi Fibercom (WWW.F-TONE.COM) DWDM optical modules solutions.

He aha ka DWDM optical module?

E like me ka haʻi ʻana o kona inoa iā mākou, ʻo ka DWDM optical module he module optical e hoʻohui i ka ʻenehana DWDM.Hoʻohana ka DWDM optical module i nā lōʻihi hawewe like ʻole e hoʻonui i nā hōʻailona optical i hoʻokahi fiber optical, a ʻaʻole e pau ka mana o kēia hana.Hoʻolālā ʻia kēia mau modula optical no ka hiki ke kiʻekiʻe, ka lōʻihi o ka lawe ʻana, hiki ke piʻi i ka 10GBPS, a hiki i ka mamao hana ke hiki i 120KM.I ka manawa like, ua hoʻolālā ʻia ka module optical DWDM e like me ke kūlana Multilateral Agreement (MSA) e hōʻoia i ka nui o ka hoʻopili ʻana o nā lako pūnaewele.Kākoʻo nā modula optical 10G DWDM iā ESCON, ATM, Fiber Channel a me 10 Gigabit Ethernet (10GBE) ma kēlā me kēia awa.ʻO nā modules optical DWDM ma ka mākeke e loaʻa pinepine: DWDM SFP, DWDM SFP +, DWDM XFP, DWDM X2 a me DWDM XENPAK optical modules, etc.

Ka hana a me ke kumu hana o DWDM optical module

ʻO ka hana maʻamau a me ke kumumanaʻo hana o ka module optical DWDM e like me nā modula optical ʻē aʻe, e hoʻohuli i nā hōʻailona uila i nā hōʻailona optical, a laila hoʻololi i nā hōʻailona optical i nā hōʻailona uila.Eia nō naʻe, ua hoʻolālā ʻia ka module optical DWDM no nā noi DWDM, a he mea pono ke haʻi ʻia aia kona mau hiʻohiʻona a me kāna mau hana.Ke hoʻohālikelikeʻia me ka'ōnaewele puʻupuʻu nui (CWDM), ua hoʻolālāʻia ka module optical DWDM no ka fiber mode hoʻokahi, a e like me ka'ōlelo maopopoʻana e ITU-T, aia ma ka DWDM nominal range o 1528.38 a 1563.86NM (channel 17 a hiki i ka 17. kaila 61).hana ma waena o nā lōʻihi nalu.Hoʻohana ʻia ia e kau i nā lako pūnaewele DWDM o ke komo kūlanakauhale a me ka pūnaewele kumu.Hele mai ia me kahi mea hoʻohui SFP 20-pin no ka hana wela-swappable.Hoʻohana ʻia kāna ʻāpana transmitter i ka laser DFB nui quantum well DWDM, ʻo ia ka laser hoʻokō Class 1 e like me ke kūlana palekana honua IEC-60825.Eia kekahi, hoʻokō nā modula optical DWDM mai nā mea hoʻolako he nui i ka maʻamau SFF-8472 MSA.ʻO nā mea hou loa i nā ʻōnaehana hoʻoili DWDM e pili ana i nā modula optical pluggable, hiki ke hana ma nā kahawai 40 a i ʻole 80.ʻO kēia hoʻokō e hōʻemi nui i ka pono o nā modula pluggable kaʻawale ke hiki ke hoʻohana ʻia ka laulā piha o nā lōʻihi hawewe me kekahi mau mea hiki ke hoʻopili ʻia ma ʻaneʻi a ma laila.

Hoʻokaʻawale i nā modula optical DWDM

ʻO ka mea maʻamau, ke nānā mākou i nā modula optical DWDM, e pili ana mākou i Gigabit a i ʻole 10 Gigabit DWDM optical modules.Wahi a nā ʻano hoʻopihapiha like ʻole, hiki ke hoʻokaʻawale ʻia nā modula optical DWDM i ʻelima mau ʻano.ʻO lākou: DWDM SFP, DWDM SFP +, DWDM XFP, DWDM X2, a me DWDM XENPAK optical modules.

Nā SFP DWDM

Hāʻawi ka DWDM SFP optical module i kahi loulou serial kiʻekiʻe me ka helu hoʻouna hōʻailona o 100 MBPS i 2.5 GBPS.Hoʻopili ʻo DWDM SFP optical module i nā koi o ka IEEE802.3 Gigabit Ethernet maʻamau a me ka kikoʻī ANSI Fiber Channel, a kūpono no ka pilina ma Gigabit Ethernet a me Fiber Channel kaiapuni.

DWDM SFP+

DWDM SFP + optical modules ua hoʻolālā kūikawā ʻia no nā mea hoʻohana a me nā ʻoihana nui e koi ana i ka multiplexing, ka hoʻouna ʻana a me ka pale ʻana i ka point-to-point, add-drop multiplexing, ring, mesh a me nā topologies pūnaewele hōkū. me ka hoʻohana ʻana i kahi ʻōnaehana hiki ke hoʻonui ʻia, hiki ke maʻalahi.Hāʻawi ʻo DWDM i nā mea lawelawe e hoʻokō i nā koi o ka nui o nā lawelawe i hōʻuluʻulu ʻia no kēlā me kēia protocol subrate me ka ʻole o ka hoʻokomo ʻana i nā fiber ʻeleʻele hou.No laila, ʻo ka DWDM SFP + optical module ke koho maikaʻi loa no ka noi bandwidth kiʻekiʻe loa o 10 Gigabit.

DWDM XFP

Hoʻopili ka DWDM XFP optical transceiver me ka kikoʻī XFP MSA o kēia manawa.Kākoʻo ia iā SONET/SDH, 10 Gigabit Ethernet a me 10 Gigabit Fiber Channel noi.

DWDM X2

ʻO DWDM X2 optical module he kiʻekiʻe kiʻekiʻe serial optical transceiver module no kiʻekiʻe-wikiwiki, 10 Gigabit noi hoʻoili ʻikepili.Hoʻopili piha kēia module me ka Ethernet IEEE 802.3AE maʻamau a he kūpono ia no nā noi 10 Gigabit Ethernet (rack-to-rack, client interconnect).Aia kēia module transceiver i kēia mau ʻāpana: transmitter me DWDM EML cooled laser, receiver me PIN type photodiode, XAUI connection interface, integrated encoder/decoder and multiplexer/demultiplexer device.

DWDM XENPAK

ʻO DWDM XENPAK module optical ka mua o ka 10 Gigabit Ethernet optical module e kākoʻo ana iā DWDM.ʻO DWDM kahi ʻenehana hoʻoili uila e hoʻouna i nā ala he nui ma ka fiber optical hoʻokahi.Me ke kōkua o ka optical amplifier EDFA, hiki i ka DWDM XENPAK optical module ke kākoʻo i ka 32-channel data transmission me kahi mamao a hiki i 200KM.A 10 Gigabit Ethernet nenoaiu e pili ana i ka DWDM 'enehana ua hoʻokō 'ia me ka pono ole i hoʻolaʻa waho mea - he optical transceiver (e hoohuli i ka hawewe mai (e laʻa: 1310NM) i DWDM wavelength) -.

Ke noi ʻana o DWDM optical module

Hoʻohana pinepine ʻia nā modula optical DWDM i nā ʻōnaehana DWDM.ʻOiai ʻoi aku ka kiʻekiʻe o ke kumukūʻai o nā modula optical DWDM ma mua o nā modula optical CWDM, ʻoi aku ka nui o ka hoʻohana ʻana o DWDM i MAN a i ʻole LAN ma ke ʻano o ka hoʻonui ʻana i nā koi.Loaʻa nā ʻano hoʻohana like ʻole DWDM optical module packaging type.Hiki ke hoʻohana ʻia ka DWDM SFP i ka pūnaewele DWDM hoʻonui ʻia, Fiber Channel, topology network ring o OADM paʻa a hoʻoponopono hou ʻia, Fast Ethernet, Gigabit Ethernet a me nā ʻōnaehana hoʻoili optical ʻē aʻe.Hoʻopili ʻo DWDM SFP + i ka maʻamau 10GBASE-ZR/ZW a hiki ke hoʻohana ʻia no nā kelepona optical 10G.Hoʻohana pinepine ʻia ʻo DWDM XFP ma kahi e hoʻokō ai i nā kūlana he nui e like me: 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 a me ITU-T G.709 maʻamau.Hoʻohana ʻia nā ʻano ʻē aʻe e like me DWDM X2 a me DWDM XENPAK no nā kumu like.Eia kekahi, hiki ke hoʻohana ʻia kēia mau modula optical DWDM no ka hoʻololi ʻana i ka hoʻololi ʻana, ke hoʻololi ʻana i nā noi backplane, a me nā kikowaena router / server, etc.

Hāʻawi ʻo HUANET i nā huahana piha no nā ʻōnaehana DWDM.ʻO kā mākou ʻoihana R&D a me ka hui ʻenehana, ma o ka ʻenehana kiʻekiʻe a me nā mana hana hou ikaika, ua hoʻopuka i nā ʻāpana optical maikaʻi loa i kā lākou papa no nā ʻōnaehana DWDM.ʻO ka laina huahana transceiver optical DWDM kekahi o kā mākou laina huahana kūʻai maikaʻi loa.Hāʻawi mākou i nā modula optical DWDM me nā ʻano pōʻai like ʻole, nā mamao hoʻouna ʻokoʻa a me nā uku hoʻoili like ʻole.Eia kekahi, kūpono nā modula optical DWDM o HUANET me nā hōʻailona ʻē aʻe, e like me CISCO, FINISAR, HP, JDSU, a me nā mea ʻē aʻe, a kūpono hoʻi i nā pūnaewele OEM e koi ana i nā kikoʻī pili.ʻO ka mea hope loa, loaʻa pū kekahi OEM a me ODM.
