Dome closures FRBU-TB

Tubing fibre management (TB)

Fibre optic splice closure FRBU-TB

Description

The FRBU is a compact ready access dome closure for use in aerial, underground and direct burial installations, available with 2 base configurations (FRBU 9 or FRBU 11) which provide 8 or 10 round cable entries (ports) and 1 oval port for loop through applications.
The closure cover, which can be fitted with a flash test valve and/or grounding feed-through, is available in 2 lengths depending on the number/type of tray selected and the configuration of the trays. It is environmentally sealed to the base using an ‘O’ ring and quick release clamp.
The cable entries are environmentally sealed using a mechanical seal (CablelokTM) or heatshink sleeves.

Base configuration:
PortNumber of portsCable diameter range - CablelokCable diameter range - heatshrink
L12x 5.5 – 20.0 mm2x 10.0 – 24.0 mm
LM12x 4.0 – 15.0 mm2x 8.0 – 22.0 mm
B2 or 44.8 – 16.5 mm6.0 – 19.0 mm
R4 or 81.7 – 9.5 mm4.0 – 11.0 mm

Its compact design, flexible base and quality makes the FRBU popular for splicing small numbers of fibre in FTTx networks, trunk application as well as CCTV installations.

Datwyler supplies the closures ready to use, with fibre management and splice trays in standard configurations.
If a standard configuration is not suitable, the closures can be supplied without splice trays and splice protection which can then be ordered separately.
Cable entry seals (Cablelok and heatshrink) and accessories such as mounting brackets must be ordered separately.
