1 General information
The installation instruction describes the necessary steps to install the FOSC-400BG. The used optical fiber
cables may consist of a loose tube, slotted core, central core or ribbon construction depending on the type
of FOSC kit. Illustrated are the loose tube construction and fusion splicing protected by heat-shrinkable splice
protectors.
The FOSC-400BG can accommodate up to 6 splice tray organizers. One tray can accommodate up to 24
fiber splices.
The closure is a single-ended design made of a thermoplastic material. The base and dome are sealed with a
clamp and an O-ring system. One oval entry port for looped (uncut) cable management and two round ports
for single cable entry/exit are included in the base. Both heat shrinkable cable seals and multi-out cold gel
seals can be used for cable sealing.
The FOSC-400BG can be installed in direct buried, manholes or aerial locations. The kit contents listed in this
installation instruction reflect the standard contents. Alternative configurations are possible.
