Ngokubanzi, amandla akhanyayo e-transceiver ye-fiber optical okanye imodyuli ye-optical yile ilandelayo: i-multimode iphakathi kwe-10db kunye ne-18db; imowudi enye yi-20km phakathi kwe -8db kunye ne -15db; kunye nemowudi enye yi-60km iphakathi kwe-5db kunye ne-12db phakathi. Kodwa ukuba amandla akhanyayo e-fiber optic transceiver avela phakathi kwe--30db kunye ne-45db, ngoko kunokwenzeka ukuba le fiber optic transceiver inengxaki.

Ungagweba njani ukuba kukho ingxaki nge-fiber optic transceiver?

(1) Okokuqala, jonga ukuba ukukhanya kwe-fiber optical transceiver okanye imodyuli ye-optical kunye nesalathiso sokukhanya kwesibini esijijekileyo sivuliwe.

a. Ukuba isalathisi se-FX se-transceiver sivaliwe, nceda uqinisekise ukuba ikhonkco yefiber i-cross-link? Esinye isiphelo se-fiber jumper sidibaniswe ngokufanayo; esinye isiphelo sidityaniswe kwimowudi yomnqamlezo.

b. Ukuba i-port optical port (FX) isalathisi se-A transceiver ivuliwe kwaye i-optical port (FX) isalathisi se-B transceiver icinyiwe, impazamo ikwi-A icala le-transceiver: enye into enokwenzeka kukuba: I-transceiver (TX) yothumelo lwamehlo i-port imbi kuba i-optical port (RX) ye-B transceiver ayifumani uphawu lokukhanya; enye into enokwenzeka kukuba: kukho ingxaki ngolu nxibelelwano lwefayibha ye-port ye-optical transceiver ye-A transceiver (TX) (intambo ye-optical okanye i-jumper optical inokwaphulwa).

c. Isalathisi esijijekileyo (TP) sicimile. Nceda uqinisekise ukuba udibaniso lwesibini olujijekileyo alulunganga okanye umdibaniso awulunganga? Nceda usebenzise i-continuity tester ukuvavanya (nangona kunjalo, izibane zesalathisi ezijijekileyo zezinye ii-transceivers kufuneka zilinde de ikhonkco yefiber idibaniswe).

d. Ezinye ii-transceivers zineechweba ezimbini ze-RJ45: (i-ToHUB) ibonisa ukuba umgca wokudibanisa kwi-switch umgca ochanekileyo; (ToNode) ibonisa ukuba umgca wokudibanisa kwi-switch ngumgca we-crossover.

e. Ezinye izandiso zeenwele zine-MPR yokutshintsha kwicala: kuthetha ukuba umgca wokudibanisa kwi-switch umgca ochanekileyo; Ukutshintsha kwe-DTE: umgca woqhagamshelo kwisitshintshi yimowudi yokuwela ngaphezulu.

(2) Ingaba intambo yokukhanya kunye ne-optical fiber jumper yophukile

a. Ukuqhagamshelwa kwentambo ye-Optical kunye nokufumanisa ukunqanyulwa: sebenzisa i-flash ye-laser, ukukhanya kwelanga, umzimba okhanyayo ukukhanyisa isiphelo esinye se-optical cable connector okanye ukudibanisa; ubone ukuba kukho ukukhanya okubonakalayo kwelinye icala? Ukuba kukho ukukhanya okubonakalayo, kubonisa ukuba ikhebula le-optical aliphulwanga.

b. Ukubona ukucinywa koxhumo lwefiber optical: sebenzisa isibane selaser, ukukhanya kwelanga, njl. ubone ukuba kukho ukukhanya okubonakalayo kwelinye icala? Ukuba kukho ukukhanya okubonakalayo, i-fiber jumper ayiphulwanga.

(3) Nokuba imowudi yesiqingatha/egcweleyo ayilunganga

Ezinye ii-transceivers zineenguqu ze-FDX kwicala: i-duplex epheleleyo; Ukutshintsha kwe-HDX: isiqingatha se-duplex.

(4) Uvavanyo ngemitha yamandla okukhanya

Amandla akhanyayo we-fiber optical transceiver okanye imodyuli ye-optical phantsi kweemeko eziqhelekileyo: i-multi-mode: phakathi kwe-10db kunye ne-18db; imowudi enye iikhilomitha ezingama-20: phakathi -8db kunye -15db; imowudi enye yeekhilomitha ezingama-60: phakathi kwe-5db kunye ne-12db; Ukuba umbane okhanyayo we-fiber optic transceiver uphakathi kwe-30db-45db, ngoko kunokugwetywa ukuba kukho ingxaki kule fiber optic transceiver.
