In order to further enhance the bandwidth of the data communication system in theodolite  The whole design of the PMD is realized by using Xenpak optical module. Its duty is responsible for converting 4-channel parallel 3.125Gbps data stream into a serial 10.3126Gbps data stream  a single channel serial optical transmission system was designed based on the studying of the 10BASE-X Gigabit Ethernet physical layer technology which meets the IEEE standard. The conversion between the 64-bit 156.25MHz TTL signals and the 4 channel 3.125Gbps PCML differential signals is carried out by FPGA  and sending out it in the form of light signals. The experimental results show that data transmission capacity was achieved a 10Gbps in the single-channel optical transmission system. It can conduct short distance transmission. The system delay is about 31lns. The bit error rates no more than 10-12  which satisfies the system demand. 2010 IEEE.

The applications based on traditional digital cameras have been limited by distance  cost and networking. Gigabit Ethernet is a data transmission standard based on the IEEE 802.3 protocol  brings several benefits to image transmission. In this paper  we compare the main features of Gigabit Ethernet and traditional digital camera interfaces. And  we design a high speed image acquisition system which overcomes these application limitations by allowing cameras to send imaging data over Gigabit Ethernet. In this system  we design a highly efficient  bidirectional conversion device based on FPGA  converts imaging data from a camera to IP packets based on UDP protocol  and sends it to PCs over inexpensive Cat-5 copper LAN cable. At the PC  the Cat-5 cable plugs into a standard Gigabit Ethernet NIC(network interface card)  eliminating the need for a frame grabber. An communications application software is used to acquire the network data  construct and display the image. A simple and efficient acknowledge and resend mechanism was used to guarantee packet delivery. The system architecture and the communication protocol are discussed in details  the experiment and results are presented in this paper. 2010 IEEE.
