Muka Aratau-Kotahi: G652D vs G657A2

1/ He aha te muka aratau-kotahi?

+ Ko te muka aratau-kotahi he muka whatu i hangaia hei kawe i te aratau mārama kotahi anake – te aratau whakawhiti.

+ Ko te diameter matua o te muka whatu aratau-kotahi he 8 ki te 10.5 μm (ko te 9μm te tikanga) ā, ko te diameter hipoki he 125 μm.

+ Ko te OS1 me te OS2 he muka whatu aratau-kotahi paerewa 9/125 μm. E whakamahia ana ngā mea e rua me ngā roangaru 1310 nm me te 1550 nm.

+ Kua hangaia te muka aratau-kotahi mō te tuku tawhiti, tere-teitei, e tautoko ana i ngā tawhiti mai i te 2 km ki te 100–160 km.

+ Te hanganga o te muka aratau-kotahi noa:

Matua:8–9 μm te whānui

Whakatakotoranga:125 μm te whānui

Pūpare:250 μm te whānui

Koti:600, 900 μm rānei te whānui

2/ G652D muka aratau-kotahi:

+ Ko te muka aratau-kotahi G652D te momo muka whatu aratau-kotahi paerewa (SMF), i whakaritea e te ITU-T mō te whakawhitiwhiti tere-teitei, tawhiti-roa.

+ Kei roto ko te hangarau "iti te tihi wai", e whakaiti ana i te ngaronga tohu i te awhe roangaru 1383 nm.

+ E mōhiotia ana mō tōna whānui whānui, tōna ngoikore iti, me tōna hototahitanga whakamuri, he mea tino pai mō ngā whatunga whakawhitiwhiti kōrero, ngā Whatunga Rohe Tāone Nui (MAN), me ngā tono muka ki te Kāinga (FTTH).

3/ G657A2 Muka Aratau-Kotahi:

+ Ko te muka aratau-kotahi G.657A2 he muka aratau-kotahi e kore e piko, e tutuki ana i ngā paerewa ITU-T, i hangaia kia mahi me te iti rawa o te ngaronga tohu i ngā radius piko kikī (tae atu ki te 7.5mm).

+ He tino hototahi ki te muka G.652D, he mea tino pai mō ngā taura taka FTTH kiato-teitei, ngā waea o roto, me ngā tāutanga whānui-piko-teitei, wāhi-iti.
