Note: 1.The product should be dried and sealed package. It is recommended that it should be use hot air to avoid moisture before using. The Primary drying temperature should be 100ºC, The temperature in using should be controlled at 120ºC, Drying time should be more than 2 hours, For the broken bag or after opening which is absorbed moisture, It should be increased drying time . 2.According to the size requirements of Loose Tube, the process parameters should be adjusted controlled by optical fiber's surplus length. 3.The above results are obtained based on specific production location and specific time to get sample. |
