Bộ chuyển đổi E1 sang quang MODEL7301
MODEL7301 Optical Fiber 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.
