FOSC 400 closures combine proven fiber management hardware from the earlier FOSC 100 closures, with a completely new sealing system. Base-to-dome seals on FOSC 400 are mechanical for ease of installation and re-entry. Cable seals feature a new heatshrink sleeve and hot melt adhesive system that is installed with a hot-air gun.

  • Compatible with most common cable types: e.g. loose tube, central core, ribbon fiber
  • FOSC splice trays hinged for access to any splice without disturbing other trays
  • Closure can be used in aerial, pedestal and underground (up to 5 meters) environments Compatible with CommScope’s CWDM modules and optical splitter trays
