Optical Fiber Modem is a optical fiber transmission equipment which use optical fiber to long-distance transmit V. 35 or E1 Or RS232/422/485 port signal, provides solution for remote connection of routers It is a kind of optical fiber equipment that usually be used in WAN group net. It provides one V. 35 or E1 Or RS232/422/485 port and one two-core fiber port, supports E1 transparent transmission and E1 frame transmission. Offers 2048K (transparent mode) or NX64Kbps (N=1~31) transmission rate.
