To identify the optical fibers and cables for telecom industry, identification labels are widely used. We keep receiving inquiries for the Permanent Identification Labels for RRU recently from contractors who take care of site maintenance. They complained about the printing disappeared after several months.

Many years ago, telecom contractors purchased and installed the Permanent Identification Labels for RRU themselves. But nowadays, telecom infrastructure suppliers like Ericsson and Huawei prefer to supply the whole solutions.

For indoor application marker label, the work environment is still ok. But for outdoor labels, rainy and sunshine will hurt the surface. Especially for the printing on the labels, acid inside the rain and UV will made the printing disappear very quickly.
