2008 is a special moment for China, because the Olympics were held this year.  The pomp of having more faces.  GRT is also actively trying to contribute its share.  GRT is an optical fiber product manufacturer integrating research and development, production and sales. Its main core businesses are optical fiber network cards, optical fiber modules, optical wave distribution equipment, optical fiber accessories, etc.  The opening of the Olympic games shows that China is a big country with high technology.  So, how does this come about like some signal transmission and transmission?  What products are used?  These are little known.

Guanghezhida, the predecessor of GRT, became the supplier of optical modules for the Olympic network center.  This ensures that the event information can be received and transmitted on the large screen immediately and accurately.  In this field of information transmission, GRT has contributed its share.

How to transmit a signal, in simple terms: signal transmission requires two servers or PC-like devices, one sending and the other receiving.  Optical modules are needed for sending and receiving.  Because simply speaking, the function of the optical module is photoelectric conversion. The sending end converts electrical signals into optical signals. After being transmitted through optical fibers, the receiving end converts optical signals into electrical signals.

GRT's self-developed modules include 1X9, BIDI, SFP, SFP+, XFP, X2, etc.  GRT has its own R&D and testing teams.  With core technology, quality and performance cannot be surpassed.  In combination with GRT's continuous adherence to national policies and strong support for the research and development of independent brands in the national optical fiber industry, it is a great honor to be the optical module supplier for the network center of the 2008 Beijing Olympic Games.
