Optical transceiver ndiyo inogumira midziyo yekufambisa kwemasaini.Optical transceivers inofanira kuiswa mufoni optical transceivers, video optical transceivers, audio optical transceivers, data optical transceivers, Ethernet optical transceivers, uye transceivers optical muzvikamu zve3: PDH, SPDH, SDH.

SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy), maererano netsanangudzo yakakurudzirwa yeITU-T, kufambiswa kwemasaini edhijitari nekumhanya kwakasiyana kuti ipe nhanho inoenderana yechimiro cheruzivo, kusanganisira nzira dzekuwanda, nzira dzemepu, uye nzira dzekubatanidza dzinoenderana. .Technical system.

SDH optical transceiverine hukuru hukuru, kazhinji 16E1 kusvika 4032E1.Ikozvino inoshandiswa zvakanyanya mumagetsi emagetsi, SDH optical terminal imhando yemagetsi emagetsi anoshandiswa mumagetsi emagetsi.

Iko kushandiswa kukuru kweSDH optical transceiver
SDH yekufambisa michina yakagadziridzwa zvakanyanya munzvimbo yakakura network network uye yakavanzika network munda.Telecom vanoshanda seChina Telecom, China Unicom, uye Radio neTerevhizheni vakatovaka SDH-based backbone optical transmission network pamwero mukuru.

Vashandi vanoshandisa hukuru-hukuru SDH zvishwe kutakura IP masevhisi, masevhisi eATM, uye optical fiber yakabatanidzwa yekuwana michina kana kurojesa zvakananga maseketi kumabhizinesi nemasangano.

Mamwe makuru-akavanzika network anoshandisawo SDH tekinoroji kumisikidza SDH optical loops mukati meiyo system kutakura masevhisi akasiyana.Semuenzaniso, iyo simba system inoshandisa SDH zvishwe kutakura data yemukati, kure kure, vhidhiyo, izwi uye mamwe masevhisi.
