ONT (Optical Network Terminal) ndi optical fiber transceiver onse ndi zida zofunika kwambiri mu optical fiber communication, koma ali ndi kusiyana koonekeratu mu ntchito, zochitika zogwiritsira ntchito ndi ntchito. Pansipa tidzawafanizitsa mwatsatanetsatane kuchokera kuzinthu zambiri.
1. Tanthauzo ndi ntchito
ONT:Monga optical network terminal, ONT imagwiritsidwa ntchito makamaka pazida zomaliza za optical fiber access network (FTTH). Ili kumapeto kwa ogwiritsa ntchito ndipo ili ndi udindo wotembenuza ma siginecha a fiber optic kukhala ma siginecha amagetsi kuti ogwiritsa ntchito athe kugwiritsa ntchito ntchito zosiyanasiyana monga intaneti, foni ndi kanema wawayilesi. ONT nthawi zambiri imakhala ndi mawonekedwe osiyanasiyana, monga mawonekedwe a Efaneti, mawonekedwe amafoni, mawonekedwe a TV, ndi zina zambiri, kuti athandizire ogwiritsa ntchito kulumikiza zida zosiyanasiyana.
Optical fiber transceiver:Fiber optic transceiver ndi Ethernet transmission media conversion unit yomwe imasinthasintha ma siginecha amagetsi opotoka mtunda wautali ndi ma sign atali atali. Nthawi zambiri amagwiritsidwa ntchito m'malo ochezera pomwe zingwe za Efaneti sizingathe kubisala ndipo ulusi wa kuwala uyenera kugwiritsidwa ntchito kukulitsa mtunda wotumizira. Ntchito ya fiber optic transceiver ndiyo kutembenuza zizindikiro zamagetsi kukhala zizindikiro za kuwala kwa maulendo aatali, kapena kusintha zizindikiro za kuwala kukhala zizindikiro zamagetsi kuti zigwiritsidwe ntchito ndi zipangizo zogwiritsira ntchito.

2. Kusiyana kwa magwiridwe antchito
ONT:Kuphatikiza pa ntchito ya kutembenuka kwa photoelectric, ONT imakhalanso ndi mphamvu yochulukitsa ndi kuchepetsa zizindikiro za deta. Nthawi zambiri imatha kunyamula mizere ingapo ya E1 ndikukhazikitsa ntchito zambiri, monga kuyang'anira mphamvu ya kuwala, malo olakwika ndi ntchito zina zoyang'anira ndi kuyang'anira. ONT ndi mawonekedwe apakati pa opereka chithandizo pa intaneti (ISPs) ndi ogwiritsa ntchito intaneti a fiber optic, ndipo ndi gawo lofunikira pa intaneti ya fiber optic.
Optical fiber transceiver:Iwo makamaka amachita photoelectric kutembenuka, sasintha encoding, ndipo sachita processing zina pa deta. Ma transceivers a Fiber optic ndi a Efaneti, amatsata protocol ya 802.3, ndipo amagwiritsidwa ntchito makamaka polumikizira mfundo. Amangogwiritsidwa ntchito potumiza zizindikiro za Efaneti ndipo ali ndi ntchito imodzi.
3. Kuchita ndi scalability
ONT:Chifukwa ONT imatha kuchulukitsa ndi kutsitsa ma siginoloji a data, imatha kuthana ndi ma protocol ndi ntchito zambiri zotumizira. Kuphatikiza apo, ONT nthawi zambiri imathandizira kufalikira kwapamwamba komanso mtunda wautali wotumizira, zomwe zimatha kukwaniritsa zosowa za ogwiritsa ntchito ambiri.
Optic fiber transceiver:Popeza amagwiritsidwa ntchito makamaka pa kutembenuka kwa kuwala kwa magetsi kwa Efaneti, ndizochepa ponena za ntchito ndi scalability. Amagwiritsidwa ntchito makamaka polumikizira mfundo-ndi-point ndipo sichithandizira kufalitsa mawiri awiri a mizere ya E1.
Mwachidule, pali kusiyana koonekeratu pakati pa ONTs ndi optical fiber transceivers ponena za ntchito, zochitika zogwiritsira ntchito, ndi ntchito. Monga optical network terminal, ONT ili ndi ntchito zambiri komanso mawonekedwe ogwiritsira ntchito ndipo ndiyoyenera ma netiweki optical fiber access; pamene ma transceivers optical fiber amagwiritsidwa ntchito makamaka potumiza zizindikiro za Ethernet ndipo ali ndi ntchito imodzi. Posankha zida, muyenera kusankha zida zoyenera kutengera zochitika ndi zosowa zapadera.
