    Nexans specification

In the context of FFTH deployment, the BlackBox closure is used as an Optical Branch Point. Designed for Straight or Butt Mid-Span installation onto a distribution cable-either crossing or terminating, the closure ensures protection of optical cables splices in undergroung works.

 

Midspan techniques and extraction techniques are well known to bring progressive deployments of optical and FTTH networks. A main cable is laid down, underground, while offering a possible later fiber connection in manholes towards the access network. Thanks to its 4 midspan ports, 2 windows of the same extraction cable can be done, allowing cutting and extracting at the same time in the same closure. These features bring installation time savings.

 

Main functions

1/ Protect the fibres

  • Ensure the fibre radius
  • Protect the fibres and the splices

2/ (Re)Protect the cables

  • Re-protect the main cables
  • Fix the main cables and distributed cables

3/ (Re)seal

4/ Frequent opening

 

Design

The closure is equipped with a body and a cover closed by 4 draw latches. The main cable is prepared on a removable plate which is in turn fastened at the rear of the closure. Mechanical tightness is perform using a double rubber seal and varions lenghts of sealant applied on the main cable depending on their diameter. The branch cables come out of the closure through 4 mechanical tightening ports, each port having the capacity to host one or several cables (see table of sealing kits). The body is equipped with a valve allowing a pressurization after installation to check tightness. The product is available in 3 versions with splicing capacities depending on the type of fibre used (72 OF for G657A2 fiber with fibre-to-fibre management, 36OF for G657A1/A2 fibre and 24OF for G652D fibre).
