Hengguang Technologies engages in the manufacture of fiber optic transmission equipment with independent intellectual property rights, it also has more than 20 years of experience on PCM30 technique.

Tianjin Hengguang Techonlogy Co Ltd., founded in 1993. At that time, to be under the jurisdiction or command of the 754 factories (Tianjin TOEC). In 1997, as 15 state-owned enterprise reform, one of the successful restructuring of the state-owned holding, Share Capital individuals whose cooperative enterprises. The number of the Group located in the compound area of 67000 square meters field. Number 6, Taishan road, Hexi District in tianjin, teh company has a total of 2600 workers.
Hengguang company currently employees 58 people engaged in optical communications product development testing and engineering services, the main products are optical transmission equipment, PCM equipment, SCADA system. Besides, the shortwave broadband antenna and power counters.
PCM30 has a long history of technology products. The protection circuit occupy more than 30% of the circuit. Because the products have been running throughout the country for nearly 20 years, has accumulated a wealth of operating experience.

SCADA systems against lightning technology, 1 point to the grounding technology, communications coding technology, analog isolation technology, are in the actual project is the valuable experience, constant light can RTU 10 is not bad. For many professionals engaged in industrial automation research institutions find it very starange.





Optical communication technology applied to field of industrial automation, application self-healing of optical communication technology, RTU not only between the master station and the communication never interrupted, but also because the mine fiber characteristics, and the communication speed has been improved significantly, and its cost is less than the cable communications. RTU communication interface can be RS232, can also be E1 interface.
