ʻO ka transceiver Optical ka mea hoʻokele no ka lawe ʻana i ka hōʻailona optical.Pono e hoʻokaʻawale ʻia nā transceivers optical i loko o nā transceivers optical kelepona, nā transceivers wikiō wikiō, nā transceivers optical leo, nā transceivers optical data, nā transceivers optical Ethernet, a me nā transceivers optical i nā ʻano 3: PDH, SPDH, SDH.

ʻO SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy), e like me ka wehewehe ʻana o ITU-T, ʻo ia ka hoʻouna ʻana i nā hōʻailona kikohoʻe ma nā wikiwiki like ʻole e hāʻawi i kahi pae kūpono o ka hoʻolālā ʻike, me nā ʻano multiplexing, nā ʻano palapala palapala, a me nā ʻano hana synchronization pili. .Pūnaehana ʻenehana.

SDH mea hoʻolele uilahe mana nui, maʻamau 16E1 a 4032E1.I kēia manawa i hoʻohana nui ʻia i nā ʻenehana optical, ʻo SDH optical terminal kahi ʻano o nā mea hoʻohana i hoʻohana ʻia i nā pūnaewele optical.

ʻO ka noi nui o SDH optical transceiver
Ua hoʻomohala nui ʻia nā mea hoʻoili SDH ma ka ʻoihana ākea ākea a me ke kahua pūnaewele pilikino.Ua kūkulu mua nā mea hoʻohana kelepona e like me China Telecom, China Unicom, a me Radio and Television i nā ʻupena hoʻoili ʻike ʻia ʻo SDH ma ke ʻano nui.

Hoʻohana nā mea hoʻohana i nā puka lou SDH nui no ka lawe ʻana i nā lawelawe IP, nā lawelawe ATM, a me ka fiber optical integrated access tool a i ʻole e hoʻolimalima pololei i nā kaapuni i nā ʻoihana a me nā ʻoihana.

Hoʻohana pū kekahi mau ʻenehana pilikino nui i ka ʻenehana SDH e hoʻonohonoho i nā puka puka SDH i loko o ka ʻōnaehana e lawe i nā lawelawe like ʻole.No ka laʻana, hoʻohana ka ʻōnaehana mana i nā puka lou SDH e lawe i ka ʻikepili i loko, ka mana mamao, wikiō, leo a me nā lawelawe ʻē aʻe.
