Ma ke ʻano laulā, ʻo ka transceiver kahi mea hana e hiki ke hoʻouna a loaʻa i nā hōʻailona, ʻoiai ʻo ka transponder kahi ʻāpana nona ka mea hana i hoʻolālā ʻia e nānā i nā hōʻailona e hiki mai ana a loaʻa nā pane i hoʻolālā mua ʻia i nā pūnaewele kamaʻilio fiber-optic. ʻO ka ʻoiaʻiʻo, ʻike pinepine ʻia nā transponders e ko lākou wikiwiki ʻikepili a me ka mamao loa e hiki ai i kahi hōʻailona ke hele. He ʻokoʻa nā transceivers a me nā transponders a ʻaʻole hiki ke hoʻololi. Hōʻike kēia ʻatikala i ka ʻokoʻa ma waena o nā transceivers a me nā repeaters.
Nā Transceiver vs. Transponders: Nā Wehewehena
I loko o nā kamaʻilio fiber optic, ua hoʻolālā ʻia nā transceivers optical e hoʻouna a loaʻa i nā hōʻailona optical. ʻO nā modula transceiver i hoʻohana pinepine ʻia he mau mea I/O (input/output) hiki ke hoʻololi wela ʻia, i hoʻokomo ʻia i loko o nā mea pūnaewele, e like me nā kuapo pūnaewele, nā kikowaena, a me nā mea like. Hoʻohana pinepine ʻia nā transceivers optical i nā kikowaena ʻikepili, nā pūnaewele ʻoihana, ka helu ao, nā ʻōnaehana pūnaewele FTTX. Nui nā ʻano transceivers, me 1G SFP, 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 200G a me 400G transceivers. Hiki ke hoʻohana ʻia me nā ʻano kaula like ʻole a i ʻole nā kaula keleawe no ka hoʻouna ʻana i kahi mamao loa i nā pūnaewele pōkole a lōʻihi paha. Eia kekahi, aia nā transceivers fiber optic BiDi e ʻae i nā modula e hoʻouna a loaʻa i ka ʻikepili ma luna o hoʻokahi fiber e hoʻomaʻalahi i nā ʻōnaehana cabling, hoʻonui i ka hiki o ka pūnaewele, a hoʻemi i nā kumukūʻai. Eia kekahi, ʻo nā modula CWDM a me DWDM e hoʻonui ana i nā nalu like ʻole ma luna o hoʻokahi fiber he kūpono no ka hoʻouna ʻana i kahi mamao loa ma nā pūnaewele WDM/OTN.
ʻOkoʻa ma waena o ka Transceiver a me ka Transponder
He mau mea hana like nā repeaters a me nā transceivers e hoʻololi i nā hōʻailona uila full-duplex i nā hōʻailona optical full-duplex. ʻO ka ʻokoʻa ma waena o lāua, ʻo ia ka hoʻohana ʻana o ka optical fiber transceiver i kahi serial interface, hiki ke hoʻouna a loaʻa i nā hōʻailona ma ka module like, ʻoiai ʻo ka repeater e hoʻohana i kahi parallel interface, e pono ai ʻelua optical fiber modules e hoʻokō i ka hoʻoili holoʻokoʻa. ʻO ia hoʻi, pono ka repeater e hoʻouna i kahi hōʻailona ma o kahi module ma kekahi ʻaoʻao, a pane ka module ma kekahi ʻaoʻao i kēlā hōʻailona.
ʻOiai hiki i kahi transponder ke lawelawe maʻalahi i nā hōʻailona parallel haʻahaʻa haʻahaʻa, ʻoi aku ka nui o kona nui a me ka hoʻohana ʻana i ka mana kiʻekiʻe ma mua o kahi transceiver. Eia kekahi, hiki i nā modula optical ke hāʻawi wale i ka hoʻololi uila-i-optical, ʻoiai hiki i nā transponders ke hoʻokō i ka hoʻololi uila-i-optical mai kekahi nalu i kekahi. No laila, hiki ke noʻonoʻo ʻia nā transponders he ʻelua transceivers i kau ʻia ma hope, kahi i ʻoi aku ka nui o ka hoʻohana ʻia no ka hoʻoili mamao loa i nā ʻōnaehana WDM i hiki ʻole ke hiki ʻia e nā transceivers optical maʻamau.
I ka hopena, ʻokoʻa maoli nā transceivers a me nā transponders i ka hana a me ka hoʻohana ʻana. Hiki ke hoʻohana ʻia nā repeaters fiber e hoʻololi i nā ʻano hōʻailona like ʻole, me ka multimode i ke ʻano hoʻokahi, ka fiber pālua i ka fiber hoʻokahi, a me hoʻokahi nalu i kekahi nalu ʻē aʻe. ʻO nā transceivers, hiki ke hoʻololi i nā hōʻailona uila i nā hōʻailona optical, ua hoʻohana lōʻihi ʻia i nā kikowaena, nā kuapo pūnaewele ʻoihana, a me nā pūnaewele kikowaena ʻikepili.
