Proterial Cable America’s Armored NanoCore™ Micro Distribution plenum cables are flexible and easy to handle. In a loose-tube design, we use 250-micron fiber optic strands, enabling a higher fiber strand count within a cable with a compact overall diameter—perfect for tight places and plenum spaces. Each fiber strand is color-coded for easy identification. Subunits with 12 strands are only 2mm in diameter.
NanoCore™ Micro Distribution cable is ideal for MPO (MTP®) style connectors where higher data rates are desired. Lightweight aluminum interlock armor is standard, eliminating the need for an inner duct or conduit and the associated costs of installation, making our plenum fiber optic cable an ideal intra-building cable solution.
Our armored plenum fiber optic cables are RoHS 3-compliant. All multimode and single-mode cables (except OM1) utilize bend-insensitive optical fibers and support applications including Gigabit, 10 Gigabit, and 40 Gigabit Ethernet. Proterial Cable America is proud to use Corning Optical Fiber as our standard optical fiber.

NanoCore Armored Plenum is our go-to choice when you need a high fiber-count, indoor plenum backbone with added robustness from aluminum interlock armor. It is designed for dense runs in data centers, central offices, and campus premises where current or future data rates include 40 and 100 Gb/s, and where eliminating separate inner duct or conduit helps keep pathways cleaner and easier to manage.
Proterial Cable America offers NanoCore Armored Plenum with loose-tube subunits that typically contain 8, 12, or 16 color-coded fibers in 2 mm tubes, allowing high strand counts in a compact outside diameter. Catalog options cover multi-mode OM3, OM4, and single-mode OS2 fibers from 24 up to 144 strands, so you can match the count and fiber type to your data center, central office, or premise backbone design.
The aluminum interlock armor on NanoCore Armored Plenum provides an integral protective layer around the loose-tube core, eliminating the need for a separate inner duct or conduit in typical indoor plenum pathways. That simplifies routing in trays and overhead spaces, helps safeguard the cable during pulls and moves, and still keeps the construction flexible and easy to handle for high-density installations.
NanoCore Armored Plenum is an indoor plenum cable with an OFCP rating and a flame-retardant thermoplastic outer jacket, making it suitable for intra-building plenum spaces, such as return-air ceilings and similar areas defined by local codes. For outdoor runs or combined indoor/outdoor routes, Proterial Cable America also offers an indoor/outdoor armored, tight-buffered plenum design. For projects that specifically require riser-rated or other constructions, our team can recommend products with more appropriate materials from our broader fiber portfolio.
NanoCore Armored Plenum is an indoor plenum cable (OFCP) with a flame-retardant thermoplastic jacket, not a low smoke zero halogen design. If your project requires LSZH, Proterial Cable America offers LSZH options in other product families, including NYCTA-approved transit cables, hybrid and wireless solutions with LSZH jackets, and CMR-LSZH versions of certain copper premise and fiber products. LSZH constructions are engineered to limit smoke and halogen by-products, such as bromine, chlorine, fluorine, and iodine in a fire, thereby reducing toxic emissions. Our team can help you select LSZH-rated part numbers that align with your safety and code requirements.
