A cikin yanayi da yawa na gyaran cikin gida, gidaje na FTTH, wannan buƙatar yana da wuya a cika. Masu gini galibi suna matse zare a cikin bututun bango masu kunkuntar, suna ƙirƙirar matse mai ƙarfi a cikin akwatunan ODF da aka ɗora a bango. Amfani da G.652D a cikin irin waɗannan yanayi yana haifar da ɓoyayyun kurakuran hanyar sadarwa waɗanda ke bayyana watanni bayan kammalawa.
A akasin haka, G.657A2 zai iya jure lanƙwasawa akai-akai a radius na 7.5 mm tare da ƙarin asara mai sarrafawa. Masu fasaha a fagen suna jin daɗin ƙarin haƙurin gini. Hanyar sadarwa mai rikitarwa, juyawa da yawa, naɗewar kabad mai ƙanƙanta ba ta sake fuskantar barazanar lalacewar sigina ba. Wannan yana rage farashin gyara matsala bayan shigarwa sosai.

3.2 Nisa da Sauƙin Yin Watsawa da Jimillar Jigilar Kaya

A cikin hanyoyin sadarwa na baya-bayan da ke waje (tushen birni zuwa birni, hanyoyin haɗin tsakiyar metro, tsawon da ya wuce kilomita 20), G.652D ya kasance babban zaɓi.

  3. Guji maɓallan haɗin gwiwa da yawa tsakanin G.652D da G.657A2 akan hanyar haɗin guda.
Tsarin haɗakarwa abu ne da aka saba gani a hanyoyin sadarwa na shiga: G.652D don kebul na ciyarwa na waje, sannan G.657A2 yana sauke kebul daga wuraren rarrabawa zuwa wuraren abokan ciniki. Wannan ƙirar haɗakarwa tana daidaita farashi da aikin lanƙwasawa, wanda masu samar da sadarwa na duniya suka karɓe shi sosai.

3.4 Abubuwan da Suka Shafi Kuɗi da Jimillar Tattalin Arzikin Aiki

Fiber ɗin G.657A2 mai ƙarancin inganci yana da ƙimar farashi idan aka kwatanta da na yau da kullun na G.652D. Ga manyan ayyukan bango na waje waɗanda ke da dubban kilomita na fiber, gibin farashi yana taruwa sosai.
Duk da haka, nazarin farashi ba zai iya mai da hankali kan farashin zare kawai ba. Muna buƙatar kimanta jimillar farashin mallakar:
