尼日利亚采购需求：ADSS光缆

I'm looking for high-quality fiber optic cables, specifically with configurations of 2 core, 4 core, and 6 core. Could you provide detailed information on the specifications, available lengths, and your pricing for these options? Additionally, please include any relevant tech sheets or certifications that might help in understanding the performance of these cables. If you have any suggestions for suitable models or alternatives that meet these criteria, I'd love to hear about them!
