Ko te whakatakotoranga G.652.D e pā ana ki tētahi momo muka whatu i tautuhia e ngā paerewa o te International Telecommunication Union (ITU-T). Ko te G.652.D tētahi o ngā momo muka whatu e whakamahia whānuitia ana i roto i ngā whatunga whakawhitiwhiti kōrero puta noa i te ao. Anei ētahi āhuatanga matua o te muka whatu G.652.D:

Aratau: He muka whatu aratau-kotahi te muka whatu G.652.D, arā, ka tautoko i te tuku i te aratau mārama kotahi. Mā tēnei ka taea te whakawhitiwhiti tere me te tawhiti mā te whakaiti i te mararatanga tohu.

Diameter Matua: Ko te whānui o te matua o te muka whatu G.652.D he tata ki te 8 ki te 10 maikiromita. Mā te whānui iti o te matua ka taea te tuku tohu mārama ki ngā tawhiti roa me te iti o te whakaiti.

Te Diameter o te Whakatakotoranga: Ko te whānui o te uhi he tata ki te 125 maikiromita. Ka karapotia te uho e te uhi, ā, ka āwhina ki te aukati i te māramatanga ki roto i te uho, ka ārai i te ngaronga o te tohu.

Whakaiti: He iti te whakaiti o te muka G.652.D, arā, he teitei tonu te kaha o te tohu i ngā tawhiti roa. He mea nui tēnei hei pupuri i te pono o te tohu i roto i ngā whatunga whakawhitiwhiti kōrero.

Te mararatanga: He iti te horapa o te muka G.652.D, arā, he rite tonu te tere o te haere o ngā roangaru mārama rerekē i roto i te muka. Mā tēnei ka whakaitihia te hē o te tohu, ā, ka taea te tuku raraunga tere-teitei.

Ngā Roanga Ngaru Whakahaere: Kua arotauhia ngā muka G.652.D mō te whakamahi me ngā roangaru huri noa i te 1310 nm me te 1550 nm, e whakamahia whānuitia ana i roto i ngā pūnaha whakawhitiwhiti kōrero whatu.

Pūtoro Piko: He iti noa te whānui piko o te muka G.652.D, tata ki te 5-10 ngā wā o te whānui o te muka. Mā tēnei ka māmā ake te tāutanga ki ngā wāhi kuiti me te kore e mōrearea te ngaronga o te tohu nā te nui rawa o te piko.

I te nuinga o te wā, e whakamahia whānuitia ana te muka whatu G.652.D i roto i ngā whatunga whakawhitiwhiti kōrero tawhiti nā te mea he tino pai ōna āhuatanga mahi, ā, he mea pai tēnei mō te tuku raraunga tere-teitei i ngā tawhiti roa.
