3onedata MODEL7302 Framed E1 to Optic Fiber Modem Converter


  • Model: MODEL7302
  • Manufactured by: 3onedata

Products Content:

MODEL7302 Optical Optic Modem converts E1 electrical signal into optical data stream for transport over single mode or multimode 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 frame/unframe for E1, so it can be used to transmit E1 signal of frame video or unframe video. The modem is capable of transmitting synchronous data with external clock at speeds from 1 Kbps up to 2.048 Mbps (n*64K), the modem can also be set to transmit asynchronous data at speeds from DC up to 64 Kbps.
