Description The FRBU is a compact, cap-ended, ready-access, fiber-optic splice closure for use in underground, direct burial and aerial installations. The mid-range capacity and port flexibility offered by the FRBU make it suitable for FTTC, trunk networks and CATV installation. The FRBU is environmentally sealed to the base using an O-ring and quick-release clamp and can be fitted with a pressure release valve and grounding feed-throughs. The cable entry/exit points in the base are environmentally sealed using either Cablelok mechanical seals or heat-shrink sleeves.

Technical Description The FRBU 11 Port B Length closure is supplied with a Polypropylene base. The base configuration of 10 round ports and 1 oval port covers a cable diameter range of 1.7 – 16.5mm when using Cablelok mechanical seals and 6.0 – 22.0mm when using heatshrink.
The mounting system is manufactured from Grade 304 stainless steel and is supplied with 6 x Hellapon Medium Side Hinged Trays giving a maximum of 72 fibre splices. The tubed closure and the position of the mounting system allows for ease of access and traceability of the fibre on to the trays.
The trays are white which makes it easy to see the colour of the fibre elements as they are routed through the fibre management system and on to the trays.
