Abstract— We report for the first time proof-of-concept trans- mission experiments for femtosecond pulse code division multiple access (CDMA) operating over kilometer lengths of optical fiber in the
While coherent modulation and demodulation generally refer to an encoder or decoder (resp.) which require access to a synchronized reference signal. Instead of referencing how data is encoded.
Cost-Effectiveness: Coaxial cable is relatively inexpensive when compared to optical fibers, making it a cost-effective choice for many communication and broadcasting systems.
Optical fiber communications use access lines known as fiber-to-the-home (FTTH), fiber-to-the-premises (FTTP), and fiber-to-the-room (FTTR). These access lines
Modern fiber-optic communication systems generally include optical transmitters that convert electrical signals into optical signals, optical fiber cables to carry the

Designing FEC coding/decoding schemes that are able to approach the Shannon limit with low complexity is important to enable future very high-throughput, low power fiber-optic communication
Connecting two optical fibers is done by fusion splicing or mechanical splicing and requires special skills and interconnection technology due to the microscopic
Low-resolution digital-to-analog converters (DACs) and analog-to-digital converters (ADCs) have low costs and low power consumption. Nevertheless, the introduced quantization noise
Thus, pulses of light are the fundamental data encoding technology used in fiber-optic communication systems.
However, the design of error-correcting codes for such a non-Gaussian fiber-optical channel is complicated and is not well investigated in the literature. Multilevel coded modulation (MLCM) uses
At the receiver, the reverse decoding operation is required to recover the original data. The encoding and decoding operations alone consti-tute optical coding. OCDMA is the use of OCDM technology to
