| Monthly Supply Capacity | 500,000 km/month | Large-scale production capacity to support telecom operators, contractors, and infrastructure projects |
Initial documentation delay, but resolved and product quality is solid
Placed an order for 96F direct burial cable for a smart city pilot project. The cable itself performed well — attenuation at 0.19 dB/km at 1550 nm and crush resistance tests passed our internal IEC 60794 verification. However, the IEC compliance certificates were missing from the initial shipment, which delayed our project approval by four days. After escalating to the account team, the documents were emailed within 6 hours and courier-sent the following day. Issue was handled professionally once raised. Subsequent reorder went smoothly with all documentation pre-included. Quality of the product itself is not in question.
