Optical transceiver chishandiso chinoshandura akawanda E1 masaini kuita masaini masaini.Optical transceiver inonziwo optical transmission equipment.Optical transceivers ane mitengo yakasiyana zvichienderana nehuwandu hweE1 (kureva, 2M) zviteshi zvinotapurirwa.Kazhinji, diki diki transceiver inogona kutumira 4 E1s.Iyo yazvino yakakura transceiver yemaziso inogona kutumira 4032 E1s, uye imwe neimwe E1 inosanganisira makumi matatu nhare.Saka, chii chinonzi transceiver optical 2m chinorevei, uye chii chiri hukama pakati peoptical transceiver E1 uye 2M?

Mhando dze optical transceivers, optical transceivers dzakakamurwa muzvikamu zvitatu: PDH, SPDH, SDH.PDH optical transceivers madiki-capacity optical transceivers, anowanzoshandiswa ari maviri maviri, anonzi point-to-point applications, uye masimba avo anowanzo 4E1, 8E1, uye 16E1.SDH optical transceiver ine hukuru hukuru, kazhinji 16E1 kusvika 4032 E1, SPDH optical transceiver, pakati pePDH neSDH.Kazhinji kutaura, transceiver yemaziso yakawanda yePDH optical transceiver, inova photoelectric conversion device.Kazhinji, optical transceiver ine one optical port uye ina 2M rate yemagetsi zviteshi ndiyo yakajairika.Telecom vanoshanda kazhinji vanoishandisa kufambisa masaini ezwi.Pahofisi yepakati, iyo optical terminal inoshandura iyo 2M ​​yemagetsi siginecha kuita chiratidzo chekuona uye ichichiendesa pane optical tambo.Mushure mekusvika kumagumo emushandisi, chiratidzo chemaziso chinoshandurwa kuita 2M chiratidzo chemagetsi, ndiko kuti, sevhisi ye2M inotumirwa kumidziyo yezwi sePCM.Uye fiber optic transceivers inonyanya kushandiswa mukukurukurirana kwedata.Iriwo rudzi rwe photoelectric conversion equipment.Kazhinji, kune anopfuura imwe optical port uye akati wandei Ethernet ports.Inoshandura masaini masaini kuita masaini eEthernet, ayo anoshandiswa kutumira masevhisi edatha kumidziyo yekutaurirana data senge ma routers kana switch.

Kune ma transceivers ekuona, 2M inoreva kuti yekupedzisira 1550 wavelength ine 2M bandwidth, iyo inoshandiswa kuendesa 485 control data, uye kune 1.25G, 155M nezvimwe zvakadaro, ndiyo bandwidth inodiwa pakufambiswa kwevhidhiyo, chaizvo 1 chiteshi chevhidhiyo. inoda 155M.Optical transceivers E1 uye 2M zvinongosiyana chete mukutaura.E1 ndiko kutaura kweboka muEuropean standard yePDH (inoenderana neNorth American standard group ndeye T1, kureva 1.5M).KuEuropean standard E1 rate i2M, saka 2M inowanzoshandiswa kumiririra E1.Zvinogona zvakare kutaurwa kuti E1 izita resainzi uye 2M ndiro zita rinozivikanwa.Munguva yeSDH, chiyero cheVC12 (uye TU-12) muhukama hweSDH multiplexing hwakanga huri pedyo ne2M (chaizvoizvo kwete 2048K), vamwe vanhu vanodanawo izvi 2M, izvo chaizvoizvo zvisina kururama.Kune E1 chiteshi pane mudziyo, inowanzodaidzwa kuti 2M chiteshi, uye inofanira kunge iri E1 kutaurisa kuve nemazvo.Saizvozvo, chiteshi che34M chinofanira kunge chiri E3, uye 45M chiteshi chinofanira kunge chiri DS3 chiteshi.140M chiteshi iE4 chiteshi.
