Isixhobo sokubonisa ukukhanya esingasemva senzelwe ukubonakalisa ukukhanya okungasemva ngesixhobo sokuqhagamshela esivela kwifayibha. Zingasetyenziselwa ukuvelisa i-interferometer yefayibha okanye ukwakha i-laser yefayibha enamandla aphantsi. Ezi zixhobo zokubonisa ukukhanya zilungele ukulinganisa ngokuchanekileyo iinkcukacha ze-retroreflector kwii-transmitters, ii-amplifier, kunye nezinye izixhobo.
Ii-retroreflectors ze-optical fiber ziyafumaneka kwiinguqulelo zefayibha ze-single-mode (SM), polarizing (PM), okanye multimode (MM). Ifilimu yesilivere enomaleko okhuselayo kwelinye icala le-fiber core inika ukubonakaliswa okuphakathi kwe-≥97.5% ukusuka kwi-450 nm ukuya kwi-wavelength ephezulu yefayibha. Isiphelo sivalelwe kwi-Ø9.8mm (0.39 in) yendlu yentsimbi engagqwaliyo ebhalwe inombolo yecandelo kuyo. Esinye isiphelo se-casing siqhagamshelwe nge-connector encinci ye-2.0 mm ye-FC/PC (SM, PM, okanye mm fiber) okanye i-FC/APC (SM okanye PM). Kwifayibha ye-PM, iqhosha elincinci lihambelana ne-axis yalo ecothayo.
I-jumper nganye inesigqubuthelo sokukhusela ukuthintela uthuli okanye ezinye izinto ezingcolisayo ukuba zinganamatheli esiphelweni seplagi. Ii-caps zeplastiki ze-CAPF ezongezelelweyo kunye nee-caps ze-fiber ze-FC/PC kunye ne-FC/APCCAPFM kufuneka zithengwe ngokwahlukeneyo.
Ii-jumpers zinokudityaniswa ngee-bushings ezifanayo, ezinciphisa ukubonakaliswa ngasemva kwaye ziqinisekise ukulungelelaniswa okusebenzayo phakathi kweziphelo ezidibeneyo zefayibha.
