Qaybta la xiriira gudbinta iyo fayberka waxaa lagu qiimeeyaa in la isku dayo in ay ugu wanaagsan doonto shabakada fayberka ooptyaalka, sababtoo ah qaybta aan la xiriirin waxaa laga helay karaa dhaafinta xudada, kordhinta xataa dhaafinta xudada (BER), iyo kordhinta fogaanta dhaafida. Malaayibtan waxay ka kooban tahay doonta qaybta gudbinta iyo khaabalka fayber ee la xiriira in ay leeyihiin geesaha, nooca (nooca halgeesi ilaa geesaha badan), diradda, iyo nooca xidhka, oo la adaptaa si aad u eg, iyo la xidhiidha. Fayberka nooca halgeesi (SMF) wuxuu leeyahay gees yar (9μm) oo la sameeyay si loo dhaafado fogaan (si ay u dhamaan 100km ama ka badan) iyadoo la isticmaalayo gudbinta oo la sameeyay diradda 1310nm, 1550nm, ama 1610nm. SMF waxaa la xidhiidha gudbinta oo la sameeyay diiwaanada laaser ee (tusaale ahaan, DFB ama EML laaser) oo soo saaraya geesyo hoos oo la xiriira, ka dhiman kordhinta. Tusaale ahaan, gudbinta 10G SFP+ oo la sameeyay 1550nm waxaa loo xidhiidha G.652D SMF ee shabakada metro ama dhaafida fogaan, isticmaalka hooska dhaafinta ee dhacay. Fayberka nooca badan (MMF), oo leeyahay geesyo badan (50μm ama 62.5μm), waxaa loo isticmaala dhaafida dhererka yar (si ay u dhamaan 550m) iyo la xidhiidha gudbinta oo la sameeyay VCSEL ama LED ee la sameeyay 850nm ama 1300nm. MMF-oyinka OM3 iyo OM4, oo la sameeyay 850nm, waxaa la xidhiidha gudbinta 10G, 40G, ama 100G (tusaale ahaan, QSFP28) ee la xidhiidha shabakada dhaqanka, sababtoo ah jumlada bandhigga iyo fogaanta waxay dhammaanayaa dhaafida caddeedka badan ee dhererka yar. Xidhka la xiriira waa qayb kale muhim. Gudbintii oo leeyahay xidhka LC waxaa la xidhiidha fayberka oo la xidhiidha LC, iyadoo la isku dayo in ay ugu hoos yihiin dhaafinta galitaanka, haddii xidhka SC ama ST loo isticmalo shabakada siyaasiyed ama shabakada hore. Xidhka oo la polishaayo (APC) waxaa loogu talagalay shabakada SMF oo la sameeyay diradda oo la xiriira (tusaale ahaan, 1550nm), sababtoo ah ay ka hoos yihiin dhaafinta soo noqnoqda iyaga oo kala duwan (UPC). Diradda la xiriira waa muhim in ay ka hortagaa dhaafinta. Tusaale ahaan, gudbinta 850nm ha noqdo in la isticmalo SMF, sababtoo ah MMF waa la sameeyay diradda, iyo midkasta. Gudbintii WDM (Wavelength Division Multiplexing) waxay uga filan in ay la xidho fayber oo dhammaystaa diradda (tusaale ahaan, ITU T G.694.1 ee C band), iyadoo la isku dayo in kanaladu ma jirto kala jir. Tafatirka hawlgalka waa qayb ka mid ah malaayibta la xidhiidha, soo saaraya jumlada dhaafinta (hawlgalka gudbinta oo ka horista midabka) iyo la isku dayo in fayberka, dhaafinta xidhka, iyo dhaafinta la xidhiidha ay karaan. Tusaale ahaan, gudbinta 40G QSFP+ oo leeyahay hawlgalka 10dB waxaa loo xidhiidha shabakada fayber ee leeyahay jumlada dhaafinta ≤10dB, lagu xidhiidha xilligan oo geesaha iyo tirada xidhka. Qaybta hawlgalka ee jannubka waxay kala wixii xidhka. Gudbintii siyaasiyed oo la qiimeeyay 40°C ilaa 85°C waxaa la xidhiidha fayberka oo la sameeyay (tusaale ahaan, la xidhiidha) ee la isticmalo jannubka ama jannubka xun, haddii gudbintii dhaqanka (0°C ilaa 70°C) ay isticmaala MMF ama SMF caadiga ah. Adeegsiga iyo tijaabinta (tusaale ahaan, OTDR ama midabka hawlgalka) ayaa xaqiijinaya in gudbinta fayberka ay jirto maqaal, iyadoo la isku dayo in ay ugu wanaagsan yihiin shabakada iyo ka goyno xidhiidha.
