ʻO ka transceiver Optical kahi mea e hoʻohuli ai i nā hōʻailona E1 i nā hōʻailona optical.Ua kapa ʻia ʻo Optical transceiver i nā mea hoʻoili optical.Loaʻa nā kumukūʻai o nā transceivers Optical e like me ka helu o nā awa E1 (ʻo ia hoʻi, 2M) i hoʻouna ʻia.ʻO ka maʻamau, hiki i ka transceiver optical liʻiliʻi ke hoʻouna i 4 E1s.Hiki i ka transceiver optical nui loa i kēia manawa ke hoʻouna i 4032 E1s, a me kēlā me kēia E1 he 30 kelepona.No laila, he aha ke ʻano o ka transceiver optical 2m, a he aha ka pilina ma waena o ka transceiver optical E1 a me 2M?

ʻO nā ʻano o nā transceivers optical, ua māhele ʻia nā transceivers optical i 3 mau ʻano: PDH, SPDH, SDH.ʻO nā transceivers optical PDH he mau transceivers optical liʻiliʻi, hoʻohana mau ʻia i nā pālua, i kapa ʻia nā noi point-to-point, a ʻo ko lākou mau mana he 4E1, 8E1, a me 16E1.He mana nui ka SDH optical transceiver, maʻamau 16E1 i 4032 E1, SPDH optical transceiver, ma waena o PDH a me SDH.ʻO ka mea maʻamau, ʻoi aku ka transceiver optical i kahi transceiver optical PDH, kahi mea hoʻololi photoelectric.ʻO ka mea maʻamau, ʻo ka transceiver optical me hoʻokahi port optical a me ʻehā 2M rate uila awa ka mea maʻamau.Hoʻohana pinepine nā mea lawelawe kelepona iā ia e hoʻouna i nā hōʻailona leo.Ma ke keʻena kikowaena, hoʻololi ke kikowaena optical i ka hōʻailona uila 2M i kahi hōʻailona optical a hoʻouna iā ia ma ke kaula uila.Ma hope o ka hōʻea ʻana i ka hopena o ka mea hoʻohana, hoʻololi ʻia ka hōʻailona optical i kahi hōʻailona uila 2M, ʻo ia hoʻi, hoʻouna ʻia ka lawelawe 2M i nā lako leo e like me PCM.A ʻoi aku ka hoʻohana ʻana o nā transceivers fiber optic i ke kamaʻilio ʻikepili.He ʻano mea hoʻololi photoelectric hoʻi ia.ʻO ka maʻamau, ʻoi aku ma mua o hoʻokahi awa optical a me kekahi mau awa Ethernet.Hoʻololi ia i nā hōʻailona optical i nā hōʻailona Ethernet, i hoʻohana ʻia no ka hoʻouna ʻana i nā lawelawe ʻikepili i nā lako kamaʻilio ʻikepili e like me nā ala ala a i ʻole nā ​​hoʻololi.

No nā transceivers optical, ʻo 2M ka mea maʻamau ʻo ka lōʻihi hawewe 1550 hope loa he 2M bandwidth, i hoʻohana ʻia e hoʻouna i ka ʻikepili mana 485, a aia nā 1.25G, 155M a me nā mea like, ʻo ia ka bandwidth i koi ʻia no ka hoʻoili wikiō, ma ke ʻano he 1 channel o ka wikiō. pono 155M.ʻOkoʻa wale nō nā transceivers Optical E1 a me 2M i ka ʻōlelo.ʻO E1 ka hōʻike o ka hui ma ka European standard of PDH (e like me ka hui maʻamau o ʻAmelika ʻAmelika ʻo T1, ʻo ia hoʻi 1.5M).No ka helu E1 maʻamau ʻEulopa he 2M, no laila hoʻohana pinepine ʻia ʻo 2M e hōʻike iā E1.Hiki ke ʻōlelo ʻia ʻo E1 ka inoa ʻepekema a ʻo 2M ka inoa maʻamau.I ka wā SDH, ua kokoke ka helu o VC12 (a me TU-12) i ka pilina SDH multiplexing i 2M (ʻoiaʻiʻo ʻaʻole 2048K), kapa kekahi poʻe i kēia 2M, ʻaʻole pololei.No ka awa E1 ma ke kelepona, ua kapa ʻia ʻo ia ʻo ke awa 2M, a ʻo ia ka E1 eloquence e pololei.E like me, ʻo ke awa 34M pono ke awa E3, a ʻo ka awa 45M ʻo ia ke awa DS3.ʻO 140M awa ka E4 awa.
