Not only can they deliver incredible data transmission and power, but they come with guaranteed performance. The unique proprietary wrap gives the cable industry-leading +15 dB alien crosstalk headroom and an internal separator reduces internal crosstalk, so the signal that reaches the device remains strong.

Fiber optic cable is a versatile tool for data centers and Superior Essex produces a variety of cable types for any premises need. We offer single mode fiber cables, multi-mode fiber cables and patch cords in loose tube, indoor/outdoor, and aramid yarn designs. Most of our cables can be manufactured to meet the number of fibers the job needs or may need in the future.

Superior Essex lives up to its firm commitment of industry-leading environmental stewardship and product transparency by sustainably manufacturing innovative, high-performing, sustainable communications cables. We produce the most sustainable communications cable products available in the marketplace – remaining sustainable both in product and process by remaining mindful of our raw materials, manufacturing, transportation, installation and end of life practices – because we firmly believe that the technology that interconnects the world should also respect it.
