The CommScope FOSC 450 Fiber Splice Tray (RH0202-000, Millennium part 521913) holds up to 24 fusion splices in an organized, stackable tray built for FOSC 450 closures. It routes and protects individual fiber splices with defined bend-radius channels, so techs can add or service splices without disturbing neighboring trays. Designed to snap into the standard FOSC 450 splice chassis, it matches the closures already deployed across most outside plant fiber networks. Millennium also stocks 12-splice and 6-splice trays for the same FOSC 450 platform.
