2 Fiber SM SMF28 Ultra Dry Flat Drop Cable PE Black spool of 1,525 meters (5,000 ft) 30" spool

Drop FTTP offers the most flexible solution for fiber to the premise applications. The Drop cable unit allows for easy location after installation. The small profile reduces cost and increases both ease of use and access to small conduits. This product is the low cost solution to the network’s last 100 meters. The durable design incorporates two dielectric rigid rods for tensile and crush protection, bracketing a single enhanced loose tube containing up to 12 optical fibers.
