Kebul ɗin fiber optic sune siraran zare waɗanda ke aika bayanai ta amfani da haske, Ana amfani da su don intanet, da sauransu. Amma zurfinsu nawa ne? Hmm, ina tsammanin ya bambanta, Wataƙila wurare daban-daban suna da ƙa'idodi daban-daban.

Da farko, ina tuna cewa a birane, akwai ƙarin kayayyakin more rayuwa, don haka wataƙila suna binne su zurfi don guje wa wasu kayan more rayuwa. Yayin da a yankunan karkara, wataƙila ba zurfi ba ne. Amma jira, me yasa za su binne su zurfi a wasu wurare? Wataƙila don kare su daga lalacewa. Kamar, idan yana ƙarƙashin hanya, ba kwa son aikin gini ya tono su. Don haka wataƙila zurfin ya dogara da wurin da kuma yuwuwar tashin hankali.

Ina tsammanin akwai ƙa'idodi ko jagorori don wannan. Wataƙila a Amurka, Hukumar Sadarwa ta Tarayya (FCC) tana da wasu ƙa'idodi? Ko wataƙila an ƙayyade ta ne ta hanyar ƙa'idodin gini na gida. Bari in yi tunani. Haka kuma, ƙasashe daban-daban na iya samun ƙa'idodi daban-daban. Misali, a Amurka da Turai, zurfin zai iya bambanta. Amma mai amfani bai ƙayyade ƙasa ba, don haka wataƙila ya kamata in ambaci ƙa'idodi na gabaɗaya kuma in lura cewa yana iya bambanta.

Ina tuna cewa zurfin binnewa na yau da kullun ga masu amfani da wutar lantarki na iya zama kusan inci 18 zuwa 24. Amma fiber optic na iya samun buƙatu daban-daban. Jira, ina tsammanin a wasu lokuta, kamar ƙarƙashin hanyoyi, suna zurfafa, wataƙila inci 36 ko fiye. Wannan ƙafa 3 ne. Amma a wurare masu laushi, kamar ƙarƙashin fili, wataƙila inci 24 ne. Akwai kuma binnewa kai tsaye idan aka kwatanta da bututun ruwa. Idan kebul ɗin yana cikin bututun ruwa, wataƙila an binne shi a wani zurfin, amma idan an binne shi kai tsaye, wataƙila zurfin daban.

Haka kuma, a cikin yanayi mai sanyi, layin sanyi na iya zama abin damuwa. Dole ne a binne ƙasa da layin sanyi don hana hawa, wanda zai iya lalata kebul. Zurfin layin sanyi ya bambanta; a jihohin arewacin Amurka, yana iya kaiwa ƙafa da yawa, yayin da a wurare masu zafi, ya yi ƙasa. Don haka wataƙila a Minnesota, suna binnewa fiye da na Florida. Amma kebul na fiber optic yawanci ba sa shafar yanayin zafi kamar, misali, bututun ruwa, amma kayan aikin shigarwa da motsi na ƙasa har yanzu suna iya zama abin damuwa.

Wani abu da za a yi la'akari da shi shine Dokar Wutar Lantarki ta Ƙasa (NEC) a Amurka. Shin hakan ya ƙayyade zurfin binnewa don kebul na sadarwa? Ina tsammanin NEC Article 800 ya ƙunshi da'irar sadarwa. Bari in yi ƙoƙarin tunawa. Don shigarwar gidaje, wataƙila inci 24 don binnewa kai tsaye, inci 18 idan a cikin bututun ruwa. Amma ban tabbata ba. Jira, NEC na iya buƙatar inci 24 don binne layukan lantarki kai tsaye, amma wataƙila fiber optics, kasancewar ƙarancin wutar lantarki, suna da ƙa'idodi daban-daban. Wataƙila za su iya zama ƙasa da haka? Amma ina buƙatar duba.

Jira, amma wasu majiyoyi sun ce galibi ana binne kebul na fiber optic a zurfin da ya yi kama da sauran kayan aiki. Misali, a Amurka, zurfin da aka saba da shi shine inci 24 zuwa 36. Amma a wasu lokuta, kamar ƙarƙashin hanyoyi ko wuraren da ke da manyan injuna, yana iya zama zurfi, har zuwa inci 48. Hakanan, lokacin da ake ketare ƙasar noma, ana iya ƙara zurfin don hana lalacewa daga noma. Don haka wataƙila inci 36 a can.

A Turai, ina tsammanin ma'auni na iya zama iri ɗaya. Misali, a Burtaniya, zurfin zai iya kaiwa kusan 450-600mm (inci 18-24) a yanayi na yau da kullun, da kuma zurfi a ƙarƙashin hanyoyi. Amma ya kamata in tabbatar. Haka kuma, ƙasashe daban-daban suna da ƙa'idodi daban-daban. Ostiraliya na iya samun ƙa'idodi daban-daban saboda dalilai daban-daban na muhalli.

Wani kusurwa kuma: ana iya binne kebul na fiber optic ta amfani da hanyoyi daban-daban. Rage rami abu ne da aka saba yi, inda ake haƙa rami sannan a sanya kebul. Ana amfani da haƙa ramin da aka saba yi a kwance lokacin da ba za su iya haƙa rami ba, kamar ƙarƙashin kogi ko hanya. Zurfin da ke nan za a sarrafa shi ta hanyar kayan aikin haƙa rami.

Amma ana iya amfani da wannan a yankunan birane masu shimfida hanya, inda za su iya yankewa da rufewa da sauri. Duk da haka, wannan ya fi ƙasa, don haka wataƙila ba abu ne da aka saba gani ba ga kebul masu nisa.

Don haka idan aka haɗa komai: zurfin da aka saba samu ya bambanta dangane da wuri, amfani da ƙasa, ƙa'idodin gida, da kuma abubuwan da suka shafi muhalli. Lambobin birni da na karkara, hanyoyi da na gidaje, takamaiman ƙasashe. Amsar yakamata ta bayyana cewa zurfin ya kama daga inci 12 (don ƙananan ramuka) har zuwa inci 48 (a ƙarƙashin hanyoyi ko a wuraren da ke da manyan injuna), tare da matsakaicin inci 24-36. Hakanan, ambaci abubuwan da suka shafi layin sanyi, kasancewar wasu kayan aiki, da bututun ruwa idan aka kwatanta da binne kai tsaye.
