Hiki i nā transceivers wikiō kikohoʻe ke loaʻa nā hana he nui, a ʻo kēlā me kēia ʻano hana e pili ana i nā koi kikoʻī ʻenehana, e like me ka wikiō wikiō, ka leo leo, ka asynchronous data index, Ethernet index, kelepona helu a pēlā aku. Hiki i nā hōʻailona ʻenehana kikoʻī ke koi i ka mea hana e hāʻawi i kahi palapala hōʻoia ʻaoʻao ʻekolu, a pono e hana nā ʻenehana loea i nā hoʻāʻo hou e like me nā hōʻailona i hāʻawi ʻia e ka mea hana ma mua o ke kūʻai ʻana i nā mea hana e nānā i nā hōʻailona ʻenehana maoli o nā mea hana a me ka pono o ka mea hana. Ke nānā nei kēia i ka wehewehe pōkole ʻana i nā hōʻailona wikiō ʻelua mai kahi hiʻohiʻona ʻenekinia.

ʻO ka bandwidth wikiō kekahi o nā pilikia i ʻōlelo pinepine ʻia. ʻAʻole lawa ka bandwidth wikiō, ʻaʻole maopopo nā kikoʻī o ka pale kiaʻi, haʻahaʻa ka hoʻonā ʻana i ka pae, a ʻike ʻia ka distortion koʻikoʻi a i ʻole ka nalowale wikiō. ʻO ia ma muli o ke koʻikoʻi o ka bandwidth wikiō i ka maikaʻi o ke kiʻi i hoʻonui ʻia e kekahi mau mea hana hewa ʻole i ka bandwidth wikiō o kā lākou huahana e hoʻopunipuni i nā mea kūʻai aku. No ka laʻana, ʻo kahi transceiver wikiō wikiō i hana ʻia e kekahi mea hana e ʻōlelo ana he 8M ka bandwidth wikiō, akā ʻo 12.5M kona alapine wikiō i hoʻolaha ʻia. Wahi a ka Nyquist sampling kānāwai, e hoʻihoʻi maoli i ka hōʻailona, ​​​​ʻo kona alapine sampling e pono ma ka liʻiliʻi loa i ʻelua mau manawa o ka hōʻailona, ​​i helu ʻia ma kēia ʻano, ʻaʻole hiki ke hoʻonui ʻia ka bandwidth video theoretical o ka transceiver optical o kēia mea hana ma mua o 6.25M i kekahi hihia. No nā hui ʻenekinia maʻamau a me nā mea hoʻohana ma ka nānā ʻana i nā kikoʻī o ke kiʻi, hiki iā lākou ke hoʻoholo i ka bandwidth wikiō o ka hāmeʻa.

ʻO APL ka pae kiʻi maʻamau, a nui ʻole nā ​​​​hui ʻenekinia i nānā nui a ʻike ʻole paha i kēia hōʻailona. Eia naʻe, inā mākou e kamaʻilio e pili ana i kahi pilikia i loaʻa i kekahi mau papahana: ua hoʻouna ʻia ka hōʻailona wikiō ma o ka transceiver optical, ke loaʻa kahi wahi keʻokeʻo nui i ke kiʻi (e like me ka hoʻomālamalama ʻana o ke kāmela e ke kukui ikaika), ke kiʻi ma e haʻalulu ka nānā ʻana, a laila ʻaʻole malihini ke limahana ʻenekinia. ʻO kēia no ka mea he haiki loa ka laulā APL o nā transceivers optical video i hana ʻia e kekahi mau mea hana. Ke loaʻa kahi wahi keʻokeʻo nui i ka hōʻailona kiʻi, hoʻonui ka ʻāpana DC i kēlā me kēia laina o ka hōʻailona kiʻi, a piʻi aʻe ka APL, e hopena i ka emi ʻana o ka amplitude o ka hōʻailona synchronization horizontal. A i ʻole nalo, ʻaʻole hiki i ka monitor ke ʻike i ka hoʻonohonoho laina a haʻalulu ka pale.
