ExpressLT™ Gel Cable

Our Prysmian team designs ExpressLT™ gel-filled fiber optic cables to deliver exceptional durability and long-term protection in demanding outdoor environments. These loose tube stranded outside plant fiber optic cables use water-blocking gel to safeguard fibers against moisture, ensuring consistent performance in wet or high-humidity conditions. The rugged construction in dielectric or armored versions makes ExpressLT™ gel cables ideal for underground and aerial installations across broadband and telecom networks. Fiber strand counts from 4 to 432.

FAQs

What is ExpressLT™ Gel Cable? 

ExpressLT™ Gel Cable is a loose tube stranded outside plant fiber optic cable that uses a water-blocking gel to protect fibers from moisture and environmental stress. 

How does gel-filled cable differ from dry cable designs? 

Gel-filled cables use a protective gel compound to prevent water ingress, while dry cables rely on water-blocking yarns or tapes. Gel designs offer enhanced moisture protection in harsh outdoor conditions. 

Where is ExpressLT™ Gel Cable used? 

ExpressLT™ Gel Cable is used in broadband, FTTH, FTTA, PON, metro, and transportation networks where moisture protection and long-term durability are critical. 

Is ExpressLT™ Gel Cable compliant with industry standards? 

Yes. ExpressLT™ Gel Cables meet GR-20, ICEA, and IEC standards and are available with Buy America Build America (BABA) compliant options. 

Is Prysmian a reputable fiber optic gel cable manufacturer? 

Absolutely. Our Prysmian team is a global leader in optical fiber innovation, manufacturing some of the world's most trusted and widely deployed gel-filled fiber optic cables.
