Rea u amohela kenyelletsong ea sehlahisoa sa rona, re thabela ho u tsebisa likhalase tsa rona tsa boleng bo holimo tsa optical. Likhalase tsa rona tsa optical li kopanya moralo oa setaele le lisebelisoa tsa boleng bo holimo ho u fa khetho ea khale le e fapaneng.

Taba ea pele, a re bueng ka moralo oa rona oa foreimi ea feshene. Likhalase tsa rona tsa optical li nka moralo oa foreimi ea feshene, e leng ea khale le e feto-fetohang, ebang e kopantsoe le liaparo tse tloaelehileng kapa tse tloaelehileng, li ka bontša botho ba hau le tatso ea hau. Foreimi e entsoe ka fiber ea acetate, e seng feela e boreleli haholoanyane, empa hape e tšoarella haholoanyane, 'me e ka boloka khanya le boleng ba eona nako e telele. Ntle le moo, re fana ka mefuta e fapaneng ea liforeimi tsa mebala eo u ka khethang ho eona, ebang u rata 'mala o motšo o motšo, o mosootho kapa oa feshene, o ka fihlela litlhoko tsa hau.

Ntle le moralo oa ponahalo ea feshene, likhalase tsa rona tsa mahlo li boetse li ts'ehetsa palo e kholo ea tlhophiso ea LOGO le mokhoa oa ho paka oa likhalase. O ka eketsa LOGO ea motho ka mong likhalaseng ho latela litlhoko tsa mofuta oa hau ho etsa hore lebitso la hau le hlahelle le ho ikhetha. Ka nako e ts'oanang, re boetse re fana ka likhetho tse fapaneng tsa ho paka likhalase, ebang ke lebokose le bonolo kapa lebokose le letle, le ka eketsa boleng le boipiletso ho lihlahisoa tsa hau.

Ka bokhutšoanyane, likhalase tsa rona tsa optical ha li na moralo oa ponahalo ea feshene feela le lisebelisoa tsa boleng bo holimo, empa hape li ts'ehetsa mokhoa oa hau oa ho itlhophisa ho fihlela litlhoko tsa hau tse fapaneng. Ebang ke sesebelisoa sa hau kapa sehlahisoa sa lebitso, likhalase tsa rona tsa mahlo li ka u tlisetsa likhetho le menyetla e mengata.
