Unviersal digital optical fibre communication terminal

The utility model general purpose digital optical fibre communication terminal relates to a disk copying machine, in particular to a long distance disk copying machine through the optical fibre copying the disk. The machine comprises a plurality of externally stored actuator or circumscription externally stored actuator faucets, a plurality of read-write internal memories, light modem and light source/photo detector which form a plurality of light communication channels through the interconnection. The light sources/photo detectors are directly connected with the same optical fibre. So the externally stored actuators can read and write the information simultaneously, and the information can be transferred and received via the same optical fibre simultaneously, or a plurality of externally stored mediums can be copied in a long-distance via the same light fibre simultaneously. The machine is combined or works together with other kinds of information input devices. The utility model not only can transfer and receive information independently, but also can produce information and reproduce information. The machine can become an absolute, one point to one point or multiple points to multiple points fixing high speed communication terminal machine.
