Introduction:MODEL7301 Optical Optic Modem converts E1 electrical signal into optical data stream for transport over single mode or multi-mode fiber optic cables. At the opposite end of the fiber, the optical stream is converted back into electrical signals of the appropriate interface such as G.703 & V.35. This fiber optic modem extends the transmission distance up to more than 100Km. The frame format of MOD-E1 is unframed for E1, so it can be used to transmit E1 signal of unframed video. Features:1.Lucency transfer E1(G.703) protocol2.Support optic fiber loop and E1 port loop3.Choice ST, FC, SC connector4.E1(G.703)interface support 120ohm(RJ-45) and 75ohm(BNC)5.Multi-mode 2KM, signal-mode 20-100KMSpecifications: Optic interfaceLine mode type: CMI Line mode rate: 2.048Mbps Operating wavelength: 850nm,1310nm or 1550nm Optic fiber connector: multi-mode adopt ST connectorsingle-mode adopt FC/SC connectorTransmission distance: Single-mode: 20,40,60,80,100,120km Multi-mode: 2km E1 interfaceStandardITU-T G.703 G.704 Data rate: 2.048MbpsWorking: Asynchronism Transparent transferOperating mode: HDB3Impedance: 75, physical interface BNC;120, physical interface RJ45 Protection: 1500V electronagnetism isolateStructureIndependent: 227.4mm (depth) 146.3mm (width) 42.6mm (height) Rack-mountable: 19in 4U standard casing Power supplyInput power:220VAC or 48VDC Power consumption: 2W Environment
