Armored Plenum rated Indoor/Outdoor tight-buffer cables are designed for LAN/WAN campus and building backbone infrastructure. These plenum jacketed cables are suitable for indoor and outdoor installations in conduit, below the frost line. The cables are designed for operation across wide temperature variations typically addressed by outside plant cables -40C to 75C. The 900µm tight buffered fibers do not require buffer tube fan-out kits and are ready for direct termination. The fiber types available (OM3, OM4 and OS2) can support Ethernet, Fiber Channel and PON applications.
