Iyini ikhebula le-Optical langaphandle?
Ikhebula le-optical langaphandle liwuhlobo lwekhebula le-optical fiber elisetshenziselwa ukudlulisa ukuxhumana. Linongqimba olwengeziwe lokuvikela olwaziwa ngokuthi i-armor noma i-metal sheathing, oluhlinzeka ngokuvikelwa ngokomzimba kuma-optical fibers, okwenza aqine kakhudlwana futhi akwazi ukusebenza ezimweni zemvelo ezinzima.
Umehluko omkhulu phakathi kwemicu yemodi eyodwa ye-G652D ne-G657A2 yile elandelayo:
1 Ukusebenza Kokugoba
Imicu ye-G657A2 inikeza ukusebenza okuphakeme kokugoba uma kuqhathaniswa nemicu ye-G652D. Yenzelwe ukumelana ne-radii egobile eqinile, okwenza ifaneleke ukusetshenziswa kumanethiwekhi okufinyelela ahamba ibanga elide lapho ukufakwa kwe-fiber kungadinga ukujika okubukhali namakhona.
2 Ukuhambisana
Ama-fiber e-G652D ahambisana nezinhlelo ezindala, okwenza kube ukukhetha okuthandwayo kokuthuthukiswa kwenethiwekhi nokufakwa lapho ukuhambisana nemishini yakudala kubalulekile. Ama-fiber e-G657A2, ngakolunye uhlangothi, angadinga ukucatshangelwa ngokucophelela kwengqalasizinda ekhona ngaphambi kokusetshenziswa.
3 Izicelo
Ngenxa yokusebenza kwayo okuphezulu kokugoba, imicu ye-G657A2 ilungele ukusetshenziswa kuzinhlelo zokusebenza ze-Fiber-to-the-Home (FTTH) kanye ne-Fiber-to-the-Building (FTTB), lapho imicu idinga ukuhamba ezindaweni eziqinile nasemakhoneni. Imicu ye-G652D ivame ukusetshenziswa kumanethiwekhi omgogodla omude kanye namanethiwekhi endawo yedolobha.
Ngamafuphi, zombili izintambo ze-G652D kanye ne-G657A2 zinezinzuzo kanye nezinhlelo zokusebenza ezihlukile. I-G652D inikeza ukuhambisana okuhle kakhulu nezinhlelo ezindala futhi ifanele amanethiwekhi ahamba isikhathi eside. Ngakolunye uhlangothi, i-G657A2 inikeza ukusebenza okungcono kokugoba, okwenza kube ukukhetha okuthandwayo kwamanethiwekhi okufinyelela kanye nokufakwa okunezidingo zokugoba okuqinile. Ukukhetha uhlobo lwentambo olufanele kuncike ezidingweni ezithile zenethiwekhi kanye nohlelo lokusebenza oluhlosiwe.
