Ngā Rerekētanga o te Muka Matua

He tinihanga pea ngā taura muka whatu — ahakoa he rite tonu te āhua o waho, ko ngā rerekētanga o roto e whakatau ana i ngā mea katoa mai i te tere ki te wāhi ka taea e koe te whakahaere. Ko ngā taura e toru — G652D, G657A1, me G657A2 — he rite tonu te whānui o te matua 9μm me te whānui o te uhi 125μm, engari he rerekētanga tēnei i reira. Anei tētahi tirohanga tata atu ki ngā mea e rerekē ai rātou me te take he mea nui.

1. Te aro ki te piko

He 30mm te iti rawa o te radius piko o ngā muka G652D, nō reira kāore e pai ki ngā piko koi. Ka heke iho te G657A1 ki te 10mm, ā, ka kuiti ake te G657A2 i te 7.5mm. He nui tēnei rerekētanga mēnā kei te kukume koe i ngā taura i roto i ngā paipa kī tonu, i ngā piko uaua ki te tae atu, i waenganui rānei i ngā pou pakitara.

Mā ngā hoahoa piko-kore i roto i ngā muka G657 ka huakina ētahi atu ara hei whakatinanatanga. Nō reira ka taea e koe te nekeneke haere i roto i ngā wāhi kuiti me te kore e manukanuka ki te hekenga o te tohu. Mō ngā whare he maha ngā piko me ngā takahuri, he tino kanapa te G657A2.

Ki te piko rawa ngā muka, ka heke te mahi a te waea. Me āta tiaki te G652D, engari ka pai ake te tohu o te waea a te G657A1 me te G657A2 ahakoa ngā tau e piko ana. Mā te whiriwhiri i te whakatauranga piko tika ka kore e raru te upoko i te heke mai.

2. Te whakaitiiti

Ko te nuinga o ngā muka G652D he iti ake te whakaiti i te kaha o te muka i ō rātou hoa G657. Mō ia km, ka taea e te G652D te ngaronga 0.35 dB i te 1310nm, ā, he paku nui ake te G657A1 me te A2 engari i raro tonu i te 0.4 dB/km.

He mea nui te iti o te whakaiti i te hononga mō ngā oma roa – pērā i te hono i ngā tāone, i ngā pokapū raraunga rānei. Mō ngā hononga poto, kāore te pikinga iti o te whakaiti i te hononga o G657 e tino whai hua. He iti rawa te ngaronga hononga o G657A1 me G657A2 (0.02-0.05 dB), ā, he ngāwari te pupuri i ngā hononga kia pakari, kia ngāwari hoki.

Mā te whakaitiiti e whakatau te tawhiti ka taea e ngā tohu te haere i mua i te hiahiatanga o ngā pūorooro. Ka ārai te G652D i ngā mate o te haere roa, ka kapi te nuinga o ngā whakaritenga o roto i te whare i ngā momo G657 me te kore he raruraru.

3. Te mararatanga

Ngā Horopaki Whakatakotoranga Pai rawa atu

Mā te whiriwhiri i te muka tino pai mō ia kaupapa ka pā nui ki te tere, te pono, me te utu o tō whatunga. He wāhi pai tō ia muka, G652D, G657A1 me G657A2 e tino pai ai te mahi.

Whatunga Haerenga Roa

He pai ngā muka G652D mō ngā whatunga tawhiti. Nā te iti o te whakaiti me te whānui o te wātea, ka waiho hei whiringa taunoa mō ngā hononga tuara e horapa ana i ngā rau, i ngā mano rānei kiromita. Ka taea e rātou te whakahaere i te tere tae atu ki te 3000 km mō te 10 Gbit/s, ā, tae atu ki te 80 km mō te 40 Gbit/s, nō reira he mea nui mō ngā hanganga waea nui.

Kāore a G657A1 me G657A2 i te tino auau mō ngā ara roa. Ko tō rāua painga matua ko te kore e aro ki ngā piko, ehara i te tawhiti. Heoi anō, i roto i ngā ara he maha ngā pikonga kuiti, he kokonga uaua rānei, ka taea e te radius piko 7.5mm o G657A2 te āwhina ki te ārai i te ngaronga tohu. Heoi, mō te nuinga o ngā ara roa, ko G652D te mea tika, ki te kore te ara e piko ana i roto i ngā tāone nui.

Ko te whiriwhiri i te muka tika me whai whakaaro ki te whānui o te hononga, te whakaiti me te āhua o te ara. I ngā oma papatahi, tuwhera, ka angitu a G652D i runga i te utu me te kounga tohu. I ngā tāone nui, me takahuri, me huri ngā taura, tera pea he pai ake te utu mō te G657A2 mō ngā tāutanga māmā ake.

muka-ki-te-kāinga

Ko G657A1 me G657A2 ngā paerewa matua mō te whakamahi i te muka-ki-te-kāinga. Nā te hoahoa kore-piko ka taea e ngā kaiwhakauru te kuhu i ngā taura mā roto i ngā wāhi uaua ki te tae atu, ngā taha rakuraku, me ngā kokonga me te kore e ngaro te tohu. Nā ēnei ka pai mō ngā kāinga noho o te tāone nui me te tāone iti, ina he mea nui te tāutanga ma, kāore e kitea.

E tumanako ana rātou kia tere, kia pono hoki te ratonga ki ō rātou kāinga. Ahakoa piko te taura i muri i ngā pakitara, i raro rānei i ngā papa, ka mau tonu te pono o te tohu mā ngā muka kore-piko. Ka whakaitihia ngā waeatanga ratonga, ā, ka koa hoki ngā kiritaki.

He pai ki ngā kaiwhakauru te G657A1 me te G657A2 nā te mea ka whakaitihia te wā tāutanga me te whakararuraru. I whakaatuhia e ngā au he nui ake ngā whatunga e whiriwhiri ana i ēnei muka mō ngā hanganga hou me ngā whakapainga.

Ngā Pokapū Raraunga

Me nui te whānui o te hononga, me ngā kokonga kikī, me ngā whatanga matotoru hoki e hiahiatia ana mō ngā pokapū raraunga. He tino pai te mahi a ngā muka G652D mō ngā oma pūwāhi ki pūwāhi, kāore he whakapaipai. I te mea ka tata haere ngā whatanga, ka kikī haere ngā huarahi, kei te neke te umanga ki a G657A1 me G657A2 mō ō rāua āhuatanga kāore e pāngia e te piko. Nā tēnei whakawhiti kua taea e ngā pokapū raraunga te kuhu i ngā taura ki roto i ngā paepae iti me te kore e manukanuka ki te hekenga o te tohu.

Mā ngā muka kāore e piko ka māmā ake ngā nekehanga me ngā huringa. Ka tere ake te whakanui ake, te whakahou rānei i ngā waea o ngā pokapū raraunga, nā te mea ka taea e ngā taura te takai me te wetewete me te kore e ngaro te mahi.

Waea ā-roto

I roto, ka mahi ngā muka G652D mō ngā kawe poto. Mēnā he iti te wāhi—pērā i roto i ngā pakitara, i ngā papa, i ngā rūma hiko kī tonu rānei—ka tino pai te G657A1 me te G657A2. Nā te iti o te porowhita piko ka iti ake te pakaru mēnā ka piko pōhēhē te taura ki te huarahi hē.

Nō reira, he mea nui te tahora o te whare, ngā nekehanga e tumanakohia ana, me te wāhi e tika ana mō te taura.

Ka āwhina a G657A1 me G657A2 i ngā whare e ātete ana ki ngā āhuatanga o āpōpō, nā te mea he maha atu ngā taputapu e honoa ana, ā, e hiahiatia ana he tere teitei ake.

Te Tāutanga me te Hononga

He mea nui te tāutanga me te honohono tika mō te mahi a te muka. Mā te tāutanga āta whakaaro, te honohono atamai me ngā taputapu tika ka pakari, ka pono hoki ō hononga, ahakoa kei te mahi koe me G652D, G657A1, G657A2 rānei. He rerekē te mahi a ia momo muka, inā koa i ngā wāhi kuiti me te taumahatanga.

Ngā Tikanga Whakahaere

Ka taea e ngā muka G657A1 me G657A2 te tu atu ki ngā piko kaha ake i te G652D. He 10mm te whānui o te piko o te G657A1, ko te G657A2 ia ka heke ki raro ki te 7.5mm. Mā tēnei ka taea e rātou te noho pai ki roto i ngā kāpata, i ngā whata, me ngā wāhi he iti te wāhi. Ahakoa tēnei ngāwari, ko te whakahaere taratara, ko ngā piko koi rānei i tua atu i tōna rohe ka taea tonu te pakaru i ngā muka, te kino rānei i te mahi.

Me noho tonu ngā taura ki runga i ō rātou tīra tae noa ki te whakamahinga, kia matara atu i te makuku me te puehu. I te wā e kawe ana, kaua e tukua ngā tīra kia taka, kaua hoki e puranga rawa. He mahi taketake tēnei, engari ka ārai i ngā pakaru moroiti, i ngā whāriki pakaru rānei e kitea ana he tohu ngoikore i te heke mai. I te wā roa, ka tere ake te whakangaro i ngā taura ki te kore e pai te whakahaere, ka piki ake ngā utu me ngā motuhanga nā te whakakapinga.

Kaua rawa ngā tohunga hangarau e wareware ki ngā karapu, ki ngā pito muka ma, me ngā taputapu kukume e tika ana, e kore e pāngia e te ahotea. Mā te tiaki i te wāhi mahi ka kore e nui te raruraru i muri mai.

Hototahitanga Hononga

Ko te hononga honohono te tikanga tino pai mō G652D, G657A1 me G657A2. Mā tēnei ka puta he hononga pakari, he iti te ngaronga. Mō G657A1 me G657A2, ko te ngaronga hononga tata ki te 0.02-0.05 dB—kāore e kitea. He teitei ake te G652D, i te 0.05-0.1 dB, engari he pai tonu mō te nuinga o ngā whakaritenga. Mā te whakaritenga ngaronga hononga tika ka mau tonu te mārama me te pumau o te tohu.

He mea noa te whakaranu i ngā momo muka, inā koa te honohono i ngā G657A1 hou, G657A2 rānei ki ngā raina G652D tawhito. He tino pai te honohono o ēnei, engari he pai te whakamahi i ngā maripi tapatapahi me ngā maripi honohono tino tika. Ka raru ētahi atu tohunga hangarau ki te honohono i ngā momo rerekē nā te mea he iti noa ngā rerekētanga o te rahi o te matua, o ngā paninga rānei. Mā te whakarite whakaaro nui me te whakamahi i ngā taputapu kua whakatikatikaina ka ea te nuinga o ēnei āwangawanga.

Ngā Wero me ngā Otinga Tāutanga

Mā te whakahaere i te taura i roto i ngā whata kīkī, i ngā kokonga koi rānei, ka neke atu a G652D i ōna rohe piko, ka tūpono ki te whati, ki te ngaronga nui rānei. Kua hangaia a G657A1 me G657A2 mō ēnei mahi, kia taea ai ngā ara uaua te whai hua me te kore e ngaro nui te tohu, 0.1-0.2 dB noa iho mō ia piko piri.

Ngā kaupapa FUBAR mō te puehu, te makuku me te rokiroki kino. Mā ngā tirotiro ngāwari—te wetewete i ngā hononga, ngā rīra maroke, ngā piko ngawari—ka roa te haere o ngā taura, ā, ka kaha tonu ngā whatunga.

Ngā Kōwhiringa Hononga me ngā Taputapu

Tīpakohia ngā hononga e tika ana mō tō muka, inā koa mō te G657A2 e hiahia ana kia nui ake ngā wāhanga e ātete ana ki te piko. He pai te mahi a ngā hononga honohono me ngā tapatapahi kounga teitei mō ngā hononga e toru, heoi, mā te whakamahi i ngā taputapu kua whakaritea mō te diameter o tō muka ka hua ake he hononga pai ake.

Ngā Pānga ki te Hoahoa Whatunga

Mā te whiriwhiri i waenga i ngā hoahoa G652D, G657A1, me G657A2 ka tautuhia te āhua me ngā tikanga o tētahi whatunga. Ka pā pea te momo muka ki te wāhi e whakatakotoria ai ngā taura, e tīpakohia ai ngā taputapu me te whakarite i ngā whakahoutanga. He kaha kei ia muka e puta mai ana i ngā wāhi rerekē—ngā wāhi kuiti, ngā mara whakapiri, ngā whatunga tawhiti rānei. Mā te ranunga tika ka taurite te utu, te mahi me te hiranga kia noho whakamua i te huringa hangarau tere.

Te Tohatoha Tahua

He maha ngā kōwhiringa whatunga e akiaki ana i te moni. He iti ake te utu o te muka G652D i te tīmatanga, ā, he mea ātaahua mō ngā hanganga iti te tahua. Ka taea e te G657A1 me te G657A2 te whakaiti i ngā whakapaunga huna a muri ake nei. Hei tauira, ka piko ake ngā muka G657—A1 ki te 10mm, A2 ki te 7.5mm—kia iti ake ai te wāhi e pau ana, ā, he iti ake hoki ngā paepae taura e hiahiatia ana i roto i ngā pokapū raraunga whaiti, i ngā kāpata iti rānei. Ka penapena tēnei i ngā utu taputapu me te mahi.

Ka ea te utu nui o ngā G657 mēnā he maha ngā piko e hiahiatia ana, he maha rānei ngā mara e whakamahia ana e koe. He mea whakaaro nui kia whakaarohia te painga o te whakatupuranga, kaua te utu nui. Mēnā ka nekehia, ka whirihorahia rānei tō whatunga i ngā wā katoa, ka taea e te whiriwhiri i te G657 te whakaiti i te tiaki me ngā raruraru tohu. Me whakarite tonu ō whakapaunga ki ngā hiahia o tō kaupapa, kaua ko te utu tāpiri anake. Whakaarohia ki tua atu i ngā utu hoko tuatahi, ki ngā whakatikatika, ki te wā kore mahi, ki ngā wāhanga tāpiri rānei.

Te Whakatūpato i te Ao o Mua

Me whai tonu ngā whatunga i ngā hangarau hou me ngā rahinga raraunga kua piki ake. Ka āwhina ngā muka G657A1 me A2 i tēnei mea nā te mea he pai tā rātou mahi i ngā wāhi kuiti, e whakarite ana i a rātou mō ngā taputapu kiato teitei me ngā taputapu o te whakatupuranga hou. I te whānui haere o ngā tāone me te whakakīkī i ngā taura ki ngā whare, ka māmā ake te piko iti o ngā muka G657 i ngā whakapainga me ngā huringa me te kore e hutia ngā aho tawhito.

Mā te piri ki te G652D ka whakawhāitihia ngā mea ka taea te whakauru ki ngā wāhi kuiti — he mea e piki haere ana te hiranga i ia tau. Ko ngā au o te waea pūkoro e tohu ana i ngā whakaritenga mōrahi ngāwari. Mā te whiriwhiri i te G657A1, i te A2 rānei i te wā hoahoa o ēnei rā ka iti ake te mamae ina hiahia koe ki te whakanui ake i te tere, i te kaha rānei. He rite ki tētahi tatau tuwhera mō ngā hangarau hou me ngā awa raraunga nui ake.

Te Pono o te Tohu

Ka pāngia te kaha o te tohu e tō whiringa muka. Mā te piko rawa i te muka ka ngoikore te tohu, ka heke, ka hapa. He pai ake te pana a ngā muka G657 i tēnei i te G652D, ka tiakina te kaha o te tohu ahakoa i ngā pikonga kuiti. He mea nui tēnei i roto i ngā whatunga e tere ana te kawe i te nui o ngā raraunga, pērā i ngā pokapū raraunga.

He tino ōrite ngā āhuatanga o ngā muka G652 me G657 mō ngā mea pēnei i te marara me te roanga ngaru, nō reira kāore te whakakapinga e whakaiti i te mahi katoa. I roto i ngā whakamahinga mahi, ko te manawanui piko o G657 te mea nui rawa atu i ngā wāhi katoa e ngokingoki ana ngā taura i roto i ngā wāhi kuiti. Hei pupuri i ngā tohu kia ma, whakamahia ngā piko ngawari, karohia ngā taura kua kōpeke, me te piri ki ngā aratohu a te kaihanga mō te muka motuhake.

Kei tua atu i ngā Paerewa

Ahakoa te āhua rite o ngā taura muka whatu, he hohonu ake te kōrero i tāu e kite nei i ngā pepa taipitopito. Ko te whakamahinga o te ao tūturu, ko ngā āhuatanga iti o tā rātou mahi toi, me ngā mea ka puta ina puta i te raina huihuinga—koinei katoa te tohu i tō rātou tūnga i roto i te kēmu. Mā te mōhio ki ēnei rerekētanga ka iti ake te mamae o te ngākau, ka atamai ake hoki ngā kōwhiringa porowhita.

Ngā Āhuatanga Hanga

Ko te āhua o tā rātou hanga i te muka G652D te mea e wehewehe ana i a ia mai i te G657A1, i te A2 rānei. He tikanga māmā noa iho ngā muka G652D kua arotauhia mō ngā tau, koia te take e kitea whānuitia ana i runga i te ipurangi. Ka wehea e te ITU-T te G652 kia whā: A, B, C, D. He mea rongonui te G652D mō tōna tihi wai iti me te whakamahinga roangaru pai ake nā ngā whakarerekētanga o ngā rauemi me te tukanga.

Me aro nui ake te hanga o te G657A1 me te A2. He mea hanga te matua karāhe ki ngā rauemi whakarei piko. Koia te take ka taea e te G657A2 te piko ki raro ki te 7.5mm anake, ko te G657A1 ia ka pēhi ki raro ki te 10mm. He mea nui ngā kōwhiringa rauemi mō tēnei. Ko te kaha ake o te piko, ko te nui ake o te mōrearea o te ngoikore, nō reira ka āwhina te hangarau karāhe me te paninga pai ki te pupuri i te iti o te ngaronga.

Te Mahi o te Ao Tūturu

Ka whakatūria e ngā tau taiwhanga he paepae, engari he ohorere te whakamahinga o te mara. Ko te G652D, me tōna whakaitiiti iti (i raro i te 0.4dB/km) te paerewa koura mō ngā oma roa. Ka kitea e koe i roto i ngā whatunga tuara, ina he iti ake ngā pekepeke i ngā ara tika. Heoi, ka tiaho a G657A1 me A2 i ngā tiriti o te tāone, i ngā whare kīkī rānei. Ko tō rātou radius piko iti—7.5mm noa iho mō A2—ka taea e rātou te neke haere i roto i ngā wāhi kuiti me te iti rawa o te ngaronga tohu.

I whakaatuhia i roto i tētahi rangahau i tētahi whare teitei, he ngāwari noa iho te whakahaere a G657A2 i ngā kokonga koi me ngā paipa kikī, engari ko G652D me whai ngohengohe me te āta tirotiro i te ara. Te Honohono G652D me G657A1) Me matapae he pikinga iti o te ngaronga o te hononga—tata ki te 0.05 ki te 0.1dB, engari he tauwhitinga tika mō te ngāwari o te whakamahi.

He mea nui ngā whakamātautau mara. Mā ngā piko, ngā hononga me ngā kukume e whakaatu ngā rohe kāore i te tirohia i roto i ngā taiwhanga. Tirohia te whakaitiiti, te PMD, te ngaronga hononga me te radius piko iti rawa i mua i te whiriwhiri i te muka. He mea nui te hototahitanga: Ka rite te G657A ki te G652D, ka māmā ake te whakapai ake.

Te Kōwhiringa Tika

Ko te whiriwhiri i ngā taura muka G.652.D, G.657.A1, me G.657.A2 me nui atu i te tirotiro noa i ngā āhuatanga. Ko te mea nui ko te mārama ki ngā kaha me te tūnga o ia momo. Kāore e rite katoa ngā kaupapa — mā te whiriwhiri tika i roto i te kēne, i te karani rānei ka taea te penapena i tō wā me tō moni, ā, ka pai tonu te haere o ngā mea!

Ka taea e tētahi rārangi arowhai māmā te āwhina. Tuatahi, tirohia te iti rawa o te porowhita piko. Me piko nui a G.652.D, tata ki te 30 mm, nō reira ka pai ake te mahi i ngā wāhi he piko ngawari me ngā oma roa. Ka taea e G.657.A1 te mahi ki ngā piko whāiti i te 10 mm, ko G.657.A2 ia ka piki ake ki te 7.5 mm.
