Product Description
1. Product Overview
This 24‑fiber armored MTP/MPO trunk cable is engineered for harsh and demanding installation environments. It features a rugged stainless‑steel spiral armor layer reinforced with aramid yarn, delivering significantly enhanced mechanical strength and extended temperature resistance compared to standard fiber trunk cables. The cable remains flexible while providing robust protection against crushing, bending stress, moisture, dust, oil, gas, and rodent damage. It supports high‑density cabling and high‑speed transmission for data centers, industrial, and outdoor/underground applications.
