Kodi ma transceiver a fiber optic ayenera kugwiritsidwa ntchito pawiri? Ngati ma transceivers a ulusi ayenera kugwiritsidwa ntchito pawiri, kodi ndi mtundu womwewo komanso mtundu womwewo? Kapena mungagwiritse ntchito mitundu ina iliyonse?
Yankho: Ma transceivers owoneka amagwiritsidwa ntchito pawiri ngati zida zosinthira zithunzi. Komabe, ndizothekanso kugwiritsa ntchito ma transceivers owoneka bwino ndi fibermasiwichi, ma transceivers a fiber ndi ma transceivers a SFP. M'malo mwake, malinga ngati kuwala kwa kuwala kwa kuwala kuli kofanana, kuyankhulana kwa Fiber-optic kungathe kupezedwa ndi mtundu womwewo wa encapsulation wa chizindikiro ndikuthandizira ndondomeko inayake.
Kawirikawiri, ma transceivers awiri-fiber (ziwiri zofunikira kuti azilankhulana bwino) sizigawika pamapeto otumizira ndi mapeto olandira. Ndi transceiver ya fiber imodzi yokha (yomwe imafunikira ulusi umodzi kuti igwirizane bwino) idzakhala ndi mapeto otumizira ndi mapeto olandira.
Kaya ndi transceiver yawiri-fiber kapena transceiver ya fiber imodzi, ndizogwirizana kugwiritsa ntchito mitundu yosiyanasiyana pawiri. Komabe, mitengo yosiyana (100 megabits ndi gigabytes) ndi mafunde osiyanasiyana (1310 nm ndi 1300 nm) sizigwirizana. Kuonjezera apo, ngakhale transceiver yamtundu umodzi wamtundu womwewo ndi awiri-fiber ndi awiri-fiber awiriawiri sangakhale ogwirizana.
Transceiver yapawiri-fiber ili ndi doko la TX (chotumiza) ndi doko la RX (doko lolandila). Madoko onsewa amatulutsa kutalika kofanana kwa 1310 nm, ndipo kulandiranso ndi 1310 nm, kotero kuti ulusi wofananirawo umalumikizidwa pakulumikizana. . Amagwiritsa ntchito ukadaulo wogawika wavelength kugawa ndi kufalitsa ndi kulandira ma siginecha awiri owoneka amitundu yosiyanasiyana pamtundu umodzi wa kuwala. Nthawi zambiri amagwiritsa ntchito mafunde a 1310 nm ndi 1550 nm.
Mitundu yosiyanasiyana ya ma transceivers owoneka imathandizira ma protocol a Ethernet. Amatha kulumikizana ndi ma transceivers amtundu womwewo, koma ma transceivers ena amawonjezera ntchito zina (monga galasi) ndikuthandizira ma protocol ena. Pankhani ya mlandu sichimathandizidwa.
