Design and implementation of optical fiber communication system
The encoded signal is an LVTTL level signal, which is first converted to a PECL level signal by the level conversion module, and then converted to an optical signal by the optical transmitter and receiver
OPTICAL SWITCHING CONTROLLER USING FPGA AS A
Abstract: This paper proposed a design of optical switching controller using FPGA for OCDMA encoder system. The encoder is one of the new technologies that use to transmit the coded data in the optical
Real-time FPGA prototyping of 15GBaud SP-16QAM coherent optical
We demonstrate a real-time coherent optical receiver based on a single field programmable gate array (FPGA) chip. To strike the balance between the performance and hardware resources, we

In order to better serve FPGA users, reduce the difficulty of system development and improve the speed of product development, a general SPDIF receiver controller with low power is designed to realize
fpga4fun
There are two optical quadrature encoders, each made from a slotted wheel, a light emitter and a pair of photodetectors. The mouse includes an IC responsible for the quadrature decoding and the
AISC 181
After combined with domestic and abroad research conditions, this design achieve experimental data transmission by optical fiber, above this basis, this design defining a custom transmission protocol,
Efficient FPGA-based LDPC Encoder Implementation for Optical
The low-density-parity-code (LDPC) code has been suggested as a forward error correction code in the ITU-T G975.1 protocol for optical communications. However,
High-Throughput LDPC Encoder/Decoder for Real-Time Coherent
We demonstrate an LDPC encoder/decoder architecture with a maximum throughput of 2229 Mbps. Implemented on an FPGA, the receiver sensitivity achieves −56 dBm@2G.
Design Approach for a FPGA based Ethernet Bridge for Optical
The main aim of this paper is to present an approach to establish optical fiber communication by employing the standard IEEE 802.3 Ethernet and Optical Sensing circuits that can be implemented
Design and FPGA Implementation of Optical Fiber Video Image
At the same time, Optical module 2 converts optical signals into electrical signals and push them to the FPGA''s GTX reception. After the data received by GTX, a 32-bit data alignment operation is
