Referring to the drawings of the block diagram in FIG. 1 and FIG. 2 this digital universal optical communication terminal 20 comprises: removable memory storage medium drive 201, 201M, readable and wntable memory 202, 202M, optical Modem 203, 203M, light source/light sensitive receptor unit 204, 204M, optical MultiplexeriDe-multiplexer 205, external removable memory storage medium drive port 207, and works with
optical Uher 3() As referring to FIG.1 and FIG.2 this invention composes removable memory storage medium drive 201 and 201M, such as floppy disk drive, removable hard disk drive.
flash memory card drive, compact disk drive, integrated circuit card (IC card) drive, Magneto-Optcal Disk drive MODD, Rewrtable Optical Disk drive RODD, laser disc drive such as CC)ROM drive, DVD drive, CD-RW drive; DVDRW drive. Readabic and writable memory 202 and 202M can be any type of readable and wr table memory storage medium such as RAM, ELPROM, flash memory, compacted disk memory, hard disk. I hey can be a stand-alone unit, or a part of the removable memory storage medium drive or a part of the optical Modem. Readable and writable memory 202 and 202M also constitute readable and writable memory functions. Optical Modem 203 and 203M use incoming data to modulate the light source and de-modulate the light picked up by the light sensitive receptor to recover the data Light sourceAight sensitive receptor unit 204 and 204M, such as a Surface Light Emitting Diode (LED), Injection Laser Diode (ILD) for light source and Field Effect Transistor (FET) for light sensitive
receptor. External removable memory storage medium drive port 207 is to connect an external removable memory storage drive, such as an external removable hard disk drive or an external compacted memory disk drive, to this universal optical communication terminal 20 which works with optical fiber 30.
FIG. I is a block diagram showing how the invention works in one specific method.
When a user wants to transfer data or distance duplicate a disk with this invention he should load the removable memory storage medium drive 201 with a corresponding medium, such as load a floppy disk drive with a floppy disk which will be distance duplicated or it carries the data he wants to transfer. This invention will accordingly read in the data from removable memory storage medium drive 201 onto the readable and writable memory 202, send it to optical Modem 203, which uses the data to modulate the light source on the light source/light sensitive receptor unit 204, and transfer it through optical fiber 30 to a receiving terminal. At the other end of the optical fiber 30 the receiving digital universal optical communication terminal 20 will pick up the light with its light sensitive receptor on the light source/light sensitive receptor unit 204, demodulate the light with optical Modem 203 to recover the data? and store/save it onto readable and writable memory 2()2 Then the user can retrieve the data Tom the readable and writable memory 202 and copy it to a removable memory storage medium with removable memory storage medium drive 201, such as to a floppy disk with a floppy disk drive.
If the transferred data is the complete image of a disk, such as the complete image of a floppy disk. this invention can thus distance duplicate the disk. Otherwise if it has just transferred some data stored on a disk, or part of a complete image of a disk, it is used just as a data transfemug terminal.
1 he read-n data can also go directly to the optical 'viodem 203 without being rosily stored saved onto the readable and wntable memory 202, as well as the received data may go directly to removable memory storage medium drive 201 This invention can also be connected to an external removable memory storage medium drive, such as an external floppy disk drive or an external hard disk drive, by its external removable memory storage medium drive port 207. If so connected this invention will read in data trom the external removable memory storage medium dove and transfer it accordingly.
This invention can also be coupled to an optical Multiplexer/DeMultiplexer which is connected to plural removable memory storage medium drives, so that this invention can transfer data or duplicate disks simultaneously with plural removable memory storage medium drives through optical fiber Now as refemng to FIG.2 another specific embodiment of this digital universal optical communication terminal 20 working with a type of optical Multiplexer/De-multiplexr 205 is described below: Removable memory storage medium drives 201 and 201M, such as a floppy disk drive and a CD-RW drive, connect separately to readable and writable memory 202 and 202M, and then to the optical Multiplexer/De-multiplexr 205. The readable and writable memory 202 and 202M will separately store/save data read in from removable memory storage medium drives 201 and 201M. The optical Modem 203, 203M and light source/light sensitive receptor unit 204, 204M can be stand-alone units or normally are included, built-in, or parts of the optical Multiplexer/De-multiplexr 205.
Each of the optical Modem and the light source/hght sensitive receptor unit set in the Multiplexer/De-multiplexr forms an independent optical communication channel. Such as the set of optical Modem 203 and light source/light sensitive receptor unit 204 forms an independent optical communication channel while the set of optical Modem 203M and light source/lght sensitive receptor unit 204M forms another independent optical communication channel. Since each channel in Multiplexer/le- multiplexr 205 works with its own channel-fxed optical Modem and light source/light sensitive receptor units each channel actually operates in the same way as described in FIG. 1, only the optical Multiplexer will simultaneously transfer data In all channels through a optical fiber 3O7 with each channel operating on its own data-modulated light on its fixed wave-length.
For example at the same time when removable memory storage medium drives 201 is reading data and storing/saving it onto readable and writable memory 202, then the data is sent to the optical MultiplexerlDemultiplexr 205 to be transferred through optical Modem 203 and fight source/light sensitive receptor unit 204 to the optical fiber 30; removable memory storage medium drives 201M can also be reading data and storing/saving it onto readable and writable memory 202M, then the data is sent to the optical Multiplexer/De-multiplexr 205 to be transferred through optical Modem 203M and light sourcellight sensitive receptor unit 204M to the optical fiber 30. This
invention with MuitplexeriDe-muitplexer, Therefore, can read In data simulianenL,usly from plural removable memory storage medium drives and transfer them smultanenously through an optical fiber When the said invention operating with an optical Multiplexer/)e-multiplexr receives data from optical fiber 30, the light sensitive receptor of light source/light sensitive receptor unit 204 or 204M in each channel will pick up its own light' de-modulate it with its own channel-lxed optical Modem 203 or 203M to recover the data, and then either send the recovered data directly to each own concerned removable memory storage medium drive 201 or 201M, or save/store it onto the readable and writable memory 202 or 202M to be retrieved and copied later to the removable memory storage medium drive 201 or 201 M Because of the functions of the Multiplexer/Demultiplexr 205 as described above, this invention with Multiplexer/Demultiplexer, therefore, can simultanenously receive data m plural optical communication channels through an optical fiber, and duplicate with plural removable memory storage medium drives simultanenously. I he data read in from the removable memory storage medium drive 201 and 201 M can also go directly to the Multiplexer/De-multiplexer 205 to be sent out. without being first stored saved onto the the readable and writable memory 202 or 202M. As well as the received data may go directly from the Multiplexer/De-multiplexer 205 to the removable memory storage medium drive 201 and 201 M without being first stored/saved onto the the readable and wntable memory 202 or 202M.
The optical Modem can be other type of optical Modem, such as an interference optical Modem for higher speed optical transmission The Multiplexer/De-multiplexer can also be other type of Multiplexer/Demultiplexer, such as Optical Wave Division Multiplexer OWDM' Optical Time Division Multiplexer OTDM, or Densified Optical Wave Division Multiplexer DOWDM. Their basic functions in this invention remain the same.
This invention can also be connected to, or operationally coupled to external optical Modem or external light source/light sensitive receptor as it can be provided with an interface for external optical Modem and external light source/light sensitive receptor.
When working this way, the data read in from the removable memory storage medium drive 201 or 201M will go through the external optical Modem to optical fiber 30; or receives data with this external optical Modem from optical fiber 30. In the same way this invention can also be connected to, or operationally coupled to external optical Multiplexer/De-multiplexer. This invention can be compacted with, or works together with other type of data in-put devices, such as with a keyboard or an electronic typewriter, especially the type of electronic typewriter which is equipped with a floppy disk drive or other type of removable memory storage mediumdrive. When so compacted or so working, the
s by- - d in data from the keyboard or the electronic iypewT'ter can be first saved onto a removable memory storage medium, such as onto a floppy disk, then be read in by this invention with removable memory storage medium drive 201 or 201 M, and transferred.
This invention can be compacted with, or works together with soundivoice recording devices, especially with such type of sound voice recording devices which records the data onto removable memory storage medium such as floppy disk, removable hard disk, laser disc such as CD-WK disc, compact memory disk, flash memory disk, magneto-optical disk, so that this invention can read in the recorded data with its removable memory storage medium dove 201 or 201M, and transfer it I his invention can be compacted with, or works together with digital cameras and video recording devices, especially with such type of digital cameras and video recording devices which records the data onto removable memory storage medium such as floppy disk, removable hard disk, laser disc such as CD-WR disc, compact memory disk, flash memory disk, magneto-optical disk, so that this invention can rea in the recorded data with its removable memory storage medium drive 201 or 201M, and transfer it.
After having received the data and duplicated the removable memory storage medium at the receiving terminal by this Invention, the transferred information can be re-
presented on the same type of devices which recorded the information.
This invention can be compacted with, or works together with image scanner or electrophoto-scanner, or Laser beam scanner, especially such type of image scanner or electrophoto-scanner or Laser beam scanner which records the scanned-in data onto removable memory storage medium such as floppy disk, removable hard disk, laser disc such as CD-WR disc, compact memory disk, flash memory disk, magneto-optical disk, so that this invention can read in the recorded data with its removable memory storage medium drive 201 or 201 M, and transfer it.
If this invention is compacted with, or works with, or operationally coupled to any of the above described data input/record devices, it is capable not only to transfer and receive information and distance duplicate disks, but also capable of creating and re-presenting inforamton by itself. If each removable memory storage medium drive, including the attached external removable memory storage medium drives, is a data nput/out-put point, then this invention can be used as a stand- alone, either a one-point-
to-multiple-points or a centerized multiple-ponts-to-multiple-points optical communication terminal by itscif.
