The CommScope FOSC450-D6-6-NT-0-D6V (Millennium part #10548, vendor #931866-000) is a single-ended fiber splice closure measuring 29.646 in long by 10 in diameter, built for underground and buried fiber optic cable applications. Supplied with no pre-installed splice tray and six cable attachment points, it supports gel cable sealing with six ground feedthrough lugs and an integrated test valve for pressure verification. Its impact-resistant polymer housing handles single fusion splicing up to 288 fibers and mass fusion up to 3,456 fibers, making it well suited to large distribution and feeder network expansions. This closure is designed for pole, strand, or wall mounting flexibility in demanding OSP environments.
