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) protocol
2.Support optic fiber loop and E1 port loop
3.Choice ST, FC, SC connector
4.E1(G.703)interface support 120ohm(RJ-45) and 75ohm(BNC)
5.Multi-mode 2KM, signal-mode 20-100KM
