Flooding Compound for Optical Fiber Cable
LF-90 flooding compound for optical fiber cable is specifically designed for the external filling of loose tube. Its optimum working temperature is room temperature, and as the temperature increases, its viscosity will gradually decrease.
It can remain soft at -50 ℃, does not drip at 80℃ . LF-90 is suitable for cold filling because of its thixotropy .It has low hydrogen generation, zero oil separation, excellent oxidation resistance and long-term stability.

China Telecom Announces Candidates for the 2018 Trunk Cable
Recently, China Telecom's 2018 trunk fiber optic cable project (the first batch) of fiber optic cable procurement projects has been completed. According to the results of the review, there are two successful candidates for fiber optic cable procurement projects.
The first successful candidate: Changfei, the bid price is 1105000.65 yuan;
The second winning candidate: Hengtong Optoelectronics, the bid price is 105,260.64 yuan.
Before that, China Telecom had already launched the introduction of optical fiber cables and outdoor optical fiber cables in 2018, with a total scale of over 50 million core kilometers, worth more than 10 billion yuan.
In addition, Jiangsu Tongding Broadband Co., Ltd. won the bid for China Telecom's 2018 trunk fiber cable project (the first batch) of fiber optic cable splice boxes, and was the only successful bidder. The bid price was 90,206.80 yuan.
