Applications：Aerial, Overhead, Outdoor
1. High quality IEC607948 IEEE1138 standards for designing, testing, and producing with grade A materials available to ensure long-term reliability.
2. Engineering support supervising and providing its own line of accessories hardware.
3. Seal stainless steel tube superior protection to the fiber optical to moisture and extreme environmental conditions such as lightning.
4. To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing a high-pressure line over 110kv.
5. Apply to the transformation of old lines.

How to Ensure the Quality and Performance of Your Fiber Optic Cable?
We control the products quality from the raw material to the finish produts All the raw material should be tested to match the Rohs standard when they arrived at our manufacture.We control the quality during the producing process by advanced technology and equipments. We test the finished products according to the test standard. Approved by various professional optical and communication product institution , GL also conduct various in-house testing in its own Laboratory and Test Center. We also conduct test with special arrangement with the Chinese Government Ministry of Quality Supervision & Inspection Center of Optical Communication Products(QSICO).
