For short distance applications, such as a network in an office building, fiber-optic cabling can save space in cable ducts. Patent Description: TECHNICAL FIELD The present invention relates to optical signal transport devices. An optical fiber is a flexible, transparent fiber made of very pure glass (silica) not much wider than a human hair that acts as a waveguide, or light pipe, to transmit light between the two ends of the fiber. Fiber Optics can be defined as: the system or branch of engineering concerned with using optic fibers. If, on the other hand, signal 1 has a lower bit rate than signal 2, an extra dummy byte is inserted into the payload of signal 2, and the mapping is delayed for one byte. An optic fiber is a filament of glass that transmits light and it most often referred to as simply “fiber”. The transmitter employs pre-biasing circuits and dummy data input. Corporation have also managed 69.1 Tbit/s over a single 240 km fiber (multiplexing 432 channels, equating to 171 Gbit/s per channel). It should be noted that in optical networking scenarios, optical TDMA (OTDMA) is preferred over optical TDM (OTDM), owing to the ease of implementation of OTDMA. The present invention relates to optical amplifiers. A novel transmitter configuration to achieve flexible scalability that is required in future optical access network is proposed. A burst of optical data in a pulse-code-modulation format within a time slot.
