Light Closure
Light Closure
Yelco’s Light Closure can be applied in numerous applications in a fiber optics network. As the name suggests, the Light Closure is a smaller and lighter solution, and can be used in any point of the network - either as a distribution point for primary network, or as a customer connection point.
1. Product Characteristics
- The splice trays can hold 24 fusion splices, heat-shrink sleeve or ANT sleeve.
- All the splice trays can hold splitters without compromising the space for the fusion splices.
- 4 round cable ports + 1 oval port.
- The Light Closure is IP68 rated.
- Cables can be sealed using either thermal sleeves and/or mechanical glands.
- Multi-way entry glands allow for more cables to be accommodated inside the closure – 2 to 12 cables multi-way glands.
- Can be wall or pole mounted, with “click” and/or sliding system.

3. Components
3.1 Splice Trays
Designed to hold large amounts of fiber in them, guaranteeing the minimum bending radius of 25mm (ITU-T G652.D fiber type). The trays can be fitted with 2 splice holders, each containing 12 fusion splices, either for standard splice protection sleeves or ANT type protection sleeves.
3.2 Splitters
They can be fitted on the sides of the trays, not compromising the space of the fusion splices.
3.3 Spare Fiber Tubes Storage Basket
In cable-to-cable connections, there may be some uncut tubes on the passing cables and they ought to be comfortably stored.
Because of that, a special basket has been designed. It allows a large number of tubes of fiber, either loose tube or micro-modules, to be stored comfortably and most importantly - in a safer way.
3.4 Special Tray for Connectors
On one side it holds the connectors; on the other side, it allows the fibers to be directed safely within the same structure.
4. Wall and Pole Support
The Light Closure can be installed by directly burying it in the ground or by using specific supports for wall and pole installations.
4.1 Metallic Wall and Pole Support
It is designed in a way so that the installer can intervene in the closure without moving it. Its “horse-shoe” like design allows it to keep the base of the closure fixed, enabling the removal of the dome.
The entire structure can be removed, by removing the 4 pins from the base. The metallic support remains installed on the wall or on the pole.
There is an accessory for the metallic support which serves as a bracket for working on a work bench.
4.2 Wall and pole support with sliding system
The base of the support is fixed on the pole or wall by means of screws or metallic clamps. The “T” shaped bracket is fixed to the dome with 4 screws. The “T” shaped bracket, slides on the base, allowing the Light Closure to slide in and out, when needed.
4.3 “Quick click IN&OUT” system
This system uses the same brackets as the Sliding System but it also has an extra special bracket that allows the Light Closure to be fixed by “clicking” it to the base. This system is mainly useful in tight spaces.
