Multi Operator Box Design Standard

1.  Objectives 

This paper attempts to describe the needs Bouygues Telecom for the manufacture of boxes optical alternative suppliers to suppliers in place on the FTTH network Bouygues Telecom to obtain from these suppliers, substitution boxes (called ” alternative boxes “in the remainder of the document), compatible and interchangeable, in the case of maintenance in particular. 

This document also specifies the main characteristics of the multi operator boxes.

4.  Contents of Delivery 

 The required service includes: 

•  The evaluation grid completed (see § 9) 
•  The manufacture of prototype housings conform to these specifications 
•  The provision of associated documentation giving the technical specifications (mechanical and optical) prototypes 
•  The test reports of cameras and couplers. 

5.  Certifications and Standards 

 The boxes will comply with the essential health and safety as defined by EU directives, and standards. 

 The alternatives boxes must have the logo of  “laser radiation” code W010.

6.  Requirements 
   1.  Compatibility with the boxes in place 

 Alternative Boxes must be fully compatible and interchangeable with the boxes from other vendors already on the FTTH network for Bouygues Telecom. 

1.  Dimensions 

 The dimensions of the alternative boxes: Width (W) x height (H) x Depth (D) must be identical to the boxes in place:

• 2.  Interfaces 

 Openings for cable entries or passages fiber boxes and garters of

alternative must be identical to those of the boxes in place (less important to the racks).

• 3.  Anchoring Systems 

 Points or anchoring systems between boxes (pins, clips …) and the holes for wall mounting enclosures of alternatives must be identical to the boxes in place:

4.  Esthetic 

 The alternative boxes should have a color identical to the boxes in place to ensure consistency of the overall aesthetics of the installation (less important to the racks).

2.  Optical performance 
   1.  Performance of the couplers (not prohibitive) 

 The table below shows the expected performance of couplers and connectorized installed in enclosures (pigtails and body bushings included).

2. Labeling / marking fiber output coupler 

 The fiber output splitter will be identified by means of rings numbered 1 to n.

 Examples: 

•  Coupler 1×4 => 1, 2, 3, 4 
•  1×16 coupler => 1, 2, …, 15, 16 

 In the case of a configuration with more couplers, color coupler ducts will be different for each module.
