Mainly introduced construction and working principle of optical transceiver which transmits two way analog base band signal by Single fiber along with single direction.

In the 1st chapter, the development and actuality of optical transceiver are introduced firstly.

With the development of optical communication technology, digital optical transceiver as a effective and reliable method of transport signal has been applied more and more widely, and the technique has been becoming maturer and maturer.

In this character,it is introduced the LabView which is the graphics languageprogramming the PCL711B, and achieve the temperature collection, and Secondary channel RS232′s interface by way of the light end machine is realized telecommunication of data.

Through the comparison with the ratios of performance and price of two kinds of optical terminals,this paper explains the rational selection and the selection principle of optical terminals during the network project,besides,it also presents the use and maintenance of the optical terminals.

This paper presents a use of opto-electronic hybrid rotary connector and the Optical line terminal realize rotary platform communications and power supply solutions.

This article unifies the actual situation of the Guangming expressway, proposed ASON and "optical line terminal + optical fiber" two different communication plans, and have carried on the detailed description to two plans, finally compares its fit and unfit quality.

With the expansion of OPTV fiber net in rural area,the original rural cable CATV-FM multiplexed net will be replaced by a new broadcast TV systems based on WDM FM optical terminal.
