He aha ka modula optical DWDM?

Hiki ke hoʻohana ʻia ka ʻenehana Dense Wavelength Division Multiplexing (DWDM) ma nā wahi like ʻole o nā pūnaewele kamaʻilio, me nā pūnaewele iwi kuamoʻo mamao loa, nā pūnaewele wahi metropolitan (MAN), nā pūnaewele komo hale noho, a me nā pūnaewele wahi kūloko (LAN).

Ma kēia mau noi, ʻoi aku hoʻi nā MAN, hoʻokomo pinepine ʻia nā modula optical liʻiliʻi (SFP) a me nā ʻano modula optical ʻē aʻe i nā ʻano kumu kiʻekiʻe. ʻO ia ke kumu e kakali nui ai ka poʻe i nā transceivers optical DWDM. E haʻi kēia kumu aʻo iā ʻoe e pili ana i ka ʻike holoʻokoʻa o nā modula optical DWDM, a e hoʻolauna iā ʻoe i nā hoʻonā modula optical DWDM ʻo Beiyi Fibercom (WWW.F-TONE.COM).

He aha ka modula optical DWDM?

E like me ka inoa e hōʻike mai nei iā mākou, ʻo ka module optical DWDM kahi module optical e hoʻohui i ka ʻenehana DWDM. Hoʻohana ka module optical DWDM i nā nalu like ʻole e hoʻonui i nā hōʻailona optical he nui i hoʻokahi fiber optical, a ʻaʻole hoʻopau kēia hana i kekahi mana. Ua hoʻolālā ʻia kēia mau module optical no ka hoʻoili ʻana i kahi mamao loa, hiki i ka wikiwiki ke hiki i 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 laulā o nā lako pūnaewele. Kākoʻo nā module optical 10G DWDM iā ESCON, ATM, Fiber Channel a me 10 Gigabit Ethernet (10GBE) ma kēlā me kēia awa. ʻO nā module optical DWDM ma ka mākeke e komo pū me: DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2 a me DWDM XENPAK optical modules, etc.

Hana a me ke kumumanaʻo hana o ka modula optical DWDM

ʻO ke kumu hana a me ke kumumanaʻo hana o ka module optical DWDM ua like ia me nā module optical ʻē aʻe, kahi e hoʻololi ai 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 kūpono ke haʻi ʻia he mau ʻano a me nā hana ponoʻī kona. Ke hoʻohālikelike ʻia me ka module optical coarse wavelength division multiplexing (CWDM), ua hoʻolālā ʻia ka module optical DWDM no ka fiber mode hoʻokahi, a e like me ka mea i wehewehe pono ʻia e ITU-T, aia ia ma ka laulā DWDM nominal o 1528.38 a 1563.86NM (channel 17 a i ke kahawai 61). hana ma waena o nā wavelengths. Hoʻohana ʻia ia e hoʻolaha i nā lako pūnaewele DWDM o ke komo ʻana i ke kūlanakauhale a me ka pūnaewele koʻikoʻi. Hele mai ia me kahi mea hoʻohui SFP 20-pin no ka hana hoʻololi wela. Hoʻohana kāna ʻāpana transmitter i kahi laser DFB well quantum DWDM he nui, ʻo ia ka laser Class 1 e like me ke kūlana palekana honua IEC-60825. Eia kekahi, ua kūlike nā modula optical DWDM mai nā mea hoʻolako he nui me ke kūlana SFF-8472 MSA. ʻO nā hana hou loa i nā ʻōnaehana hoʻoili DWDM e komo pū me nā modula optical pluggable, tunable i hiki ke hana ma nā kahawai 40 a i ʻole 80. Hoʻemi nui kēia hoʻokō i ka pono no nā modula pluggable kaʻawale ke hiki ke hoʻoponopono ʻia ka laulā piha o nā nalu me kekahi mau mea pluggable ma aneʻi a ma laila.

Ka Hoʻokaʻawale ʻana o nā modula optical DWDM

ʻO ka maʻamau, ke kuhikuhi mākou i nā modula optical DWDM, kuhikuhi mākou i nā modula optical Gigabit a i ʻole 10 Gigabit DWDM. Wahi a nā ʻano hoʻopili like ʻole, hiki ke hoʻokaʻawale nui 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 modula optical DWDM SFP i kahi loulou serial wikiwiki me ka helu hoʻoili hōʻailona o 100 MBPS a i 2.5 GBPS. Kūlike ka modula optical DWDM SFP me nā koi o ke kūlana IEEE802.3 Gigabit Ethernet a me nā kikoʻī ANSI Fiber Channel, a kūpono no ka hoʻopili ʻana ma nā wahi Gigabit Ethernet a me Fiber Channel.

DWDM SFP+

Ua hoʻolālā kūikawā ʻia nā modula optical DWDM SFP+ no nā mea hoʻohana a me nā ʻoihana nui e pono ai ka multiplexing, ka hoʻoili ʻana a me ka pale ʻana i nā topologies pūnaewele point-to-point, add-drop multiplexing, ring, mesh a me nā hōkū. Nā noi ʻikepili wikiwiki, mālama, leo a me ke wikiō, me ka hoʻohana ʻana i kahi ʻōnaehana scalable, flexible, a me ke kumukūʻai kūpono. Hiki i ka DWDM i nā mea lawelawe ke hoʻokō i nā koi o ka nui o nā lawelawe i hōʻuluʻulu ʻia no kekahi protocol subrate me ka ʻole o ka hoʻokomo ʻana i ka fiber ʻeleʻele hou. No laila, ʻo ka modula optical DWDM SFP+ ke koho maikaʻi loa no ka noi bandwidth kiʻekiʻe loa o 10 Gigabit.

DWDM XFP

Ua kūlike ka mea hoʻololi ʻike maka DWDM XFP me ke kikoʻī XFP MSA o kēia manawa. Kākoʻo ia i nā noi SONET/SDH, 10 Gigabit Ethernet a me 10 Gigabit Fiber Channel.

DWDM X2

ʻO ka module optical DWDM X2 kahi module transceiver optical serial hana kiʻekiʻe no nā noi hoʻoili ʻikepili wikiwiki, 10 Gigabit. Ua kūlike kēia module me ke kūlana Ethernet IEEE 802.3AE a kūpono hoʻi no nā noi kamaʻilio ʻikepili 10 Gigabit Ethernet (rack-to-rack, client interconnect). Aia kēia module transceiver i nā ʻāpana aʻe: ka mea hoʻoili me ka laser DWDM EML i hoʻoluʻu ʻia, ka mea hoʻokipa me ke ʻano PIN photodiode, ka pilina pili XAUI, ka encoder/decoder i hoʻohui ʻia a me ka hāmeʻa multiplexer/demultiplexer.

DWDM XENPAK

ʻO ka module optical DWDM XENPAK ka module optical 10 Gigabit Ethernet mua e kākoʻo ana iā DWDM. ʻO DWDM kahi ʻenehana hoʻoili optical e hoʻoili ana ma o nā kahawai he nui ma ka fiber optical like. Me ke kōkua o ka amplifier optical EDFA, hiki i ka module optical DWDM XENPAK ke kākoʻo i ka hoʻoili ʻikepili 32-channel me kahi mamao a hiki i 200KM. Hoʻokō ʻia kahi ʻōnaehana 10 Gigabit Ethernet e pili ana i ka ʻenehana DWDM me ka ʻole o ka pono no kahi hāmeʻa waho i hoʻolaʻa ʻia - kahi transceiver optical (e hoʻololi i ka nalu mai (e laʻa: 1310NM) i ka nalu DWDM) -.

Ka hoʻohana ʻana o ka modula optical DWDM

Hoʻohana pinepine ʻia nā modula optical DWDM i nā ʻōnaehana DWDM. ʻOiai ʻoi aku ke kiʻekiʻe o ke kumukūʻai o nā modula optical DWDM ma mua o nā modula optical CWDM, ʻoi aku ka nui o ka hoʻohana ʻia ʻana o DWDM ma MAN a i ʻole LAN e pili ana i nā koi e hoʻonui nei. Loaʻa nā noi like ʻole o nā ʻano hoʻopili modula optical DWDM. Hiki ke hoʻohana ʻia ʻo DWDM SFP i ka pūnaewele DWDM i hoʻonui ʻia, Fiber Channel, topology pūnaewele apo o OADM paʻa a hoʻonohonoho hou ʻia, Fast Ethernet, Gigabit Ethernet a me nā ʻōnaehana hoʻoili optical ʻē aʻe. Kūlike ʻo DWDM SFP+ me ke kūlana 10GBASE-ZR/ZW a hiki ke hoʻohana ʻia no nā kaula optical 10G. Hoʻohana pinepine ʻia ʻo DWDM XFP i kahi e kūlike ai me 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 nā kūlana ITU-T G.709. 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 nā interfaces switch-to-switch, nā noi switching backplane, a me nā interfaces router/server, a pēlā aku.

Hāʻawi ʻo HUANET i kahi laulā piha o nā huahana no nā ʻōnaehana DWDM. ʻO kā mākou keʻena R&D a me ka hui loea, ma o ka ʻenehana holomua a me nā hiki hana hou ikaika, ua hana 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 pūʻolo like ʻole, nā mamao hoʻoili like ʻole a me nā helu hoʻoili like ʻole. Eia kekahi, kūpono nā modula optical DWDM a HUANET me nā hōʻailona ʻē aʻe, e like me CISCO, FINISAR, HP, JDSU, a pēlā aku, a kūpono hoʻi no nā pūnaewele OEM e pono ai nā kikoʻī hoʻohālikelike. ʻO ka hope loa, loaʻa pū kekahi ʻo OEM a me ODM.
