90um ama 600um xidhid adag, dun aramid, jaakad ololaysa oo jilicsan.
Fiber-xidhka adagi waa ay fududahay in la iska bixiyo oo waxa uu leeyahay hawl-qabad heersare ah oo dib u ololeeya. Yarn Aramid waxaa loo isticmaalaa sidii xubin xoog leh si ay u siiso fiilada xoog xajin oo aad u fiican.
Jaketka qaab-dhismeedka 8 ee jaantusku wuxuu fududeeyaa laanta.
Maaddada jaakada sare waxay leedahay faa'iidooyin badan, sida inay yihiin ka-hortagga daxalka, ka-hortagga biyaha, shucaaca ultraviolet-ka-hortagga, olol-celiska, iyo aan waxyeello u lahayn deegaanka.
Qaab-dhismeedka dhammaan-dielectric wuxuu ka ilaaliyaa faragelinta korantada.
Naqshad cilmiyeed oo leh farshaxan farsamayneed oo halis ah. Ku habboon SM fiber iyo MM fiber (50um iyo 62.5um).

Xadhkaha OYI waxay ku duuduuban yihiin bakelite, alwaax, ama durbaanno alwaax bir ah. Inta lagu jiro gaadiidka, qalabka saxda ah waa in la isticmaalo si looga fogaado waxyeellaynta xirmada iyo in si fudud loogu maareeyo. Fiilooyinka waa in laga ilaaliyaa qoyaanka, laga ilaaliyaa heerkulka sare iyo dhimbilaha dabka, laga ilaaliyo foorarsiga xad dhaafka ah iyo burburinta, lagana ilaaliyo cidhiidhiga farsamada iyo dhaawaca. Looma ogola in uu haysto laba dherer oo xadhig ah hal durbaan, labada darafna waa in la xidhaa. Labada daraf waa in lagu xidhaa gudaha durbaanka, oo dhererka kaydka ee xadhig aan ka yarayn 3 mitir waa in la bixiyaa.
Midabka calaamadaynta fiilada waa caddaan. Daabacaadda waa in lagu fuliyaa 1 mitir galka dibadda ee fiilada. Halyeyga calaamadaynta galka dibadda waa la bedeli karaa iyadoo loo eegayo codsiyada isticmaalaha.
Warbixinta imtixaanka iyo shahaado bixinta waa la bixiyay.
