Mtengo wa 1550EA
1550EA SERIES ITU ONSE C-BAND TURN-ABLE EXTERNAL MODULATION OPTICAL TRANSMITTER
Mawonekedwe
◆ High khalidwe: choyambirira wapawiri mayikirowevu luso latsopano luso, RF predistortion luso inshuwaransi mu mkhalidwe wa khalidwe CNR = 53dB, dongosolo akhoza kupeza yaikulu CTB.CSO.SBS index.
◆ Kusinthasintha: ukadaulo wa modulator wakunja umatsimikizira kugwira ntchito kwa CSO, kupititsa patsogolo mphamvu ya fiber kuwala, kupeza mtunda wautali.SBS: 13-19, OMI, ITU wavelength chosinthika, AGC/MGC chosankhika, gwiritsani ntchito maukonde osiyanasiyana.
◆ Mwachidziwitso: Laser ndi okwera mtengo kwambiri makina zigawo zikuluzikulu, makina okonzeka ndi microprocessor oyang'anira boma la laser, gulu LCD zenera amasonyeza magawo ntchito.
◆ Mtundu wa Network: Sankhani All-piece status monitoring transponder chitsimikizo kuti mukwaniritse mulingo wadziko lonse ndikugwirizana ndi muyezo wa SCTE HMS, umathandizira kuthekera kowunikira kasamalidwe ka netiweki.(Pulagi mu mtundu magetsi): kutengera zotayidwa mbiri pulagi mu mtundu lophimba mphamvu kotunga, akhoza ntchito pa 85 265Vac City Network Voltage, Komanso posankha DC48V magetsi (kusungitsa chofunika);chassis kuzirala kuwongolera kutentha.
