Outside plant cables are not rated for UL CMR or CMP listing and when used inside buildings the National Electrical Code* requires the cable be placed inside metal conduit (NEC article 800-50, exception 2). In addition to NEC regulations, special state, county and local building/fire codes may apply when engineering projects utilizing this type of cable. The NEC allows OSP cable to be extended from the outside a maximum of 50 feet to allow a termination to be made.
