Function
By grouping the two functions together, the combined splicing-patching module is used to connect 48 fibers cables while still retaining operational convenience (for SC or E2000 connectors).
The proximity of the two functions also results in a reduction of pigtail lengths.
Design
The combined-function modules a space reserved for splicing of the incoming tubed fibres, as well as a frontal space devoted to jumpering. Splicing is performed with conventional cassettes.
Jumpering is effected on strips which can be preequipped or not with connectors for connection to optical fibres. Each shelf-unit can have up to 24 connectors.
The module is compatible with the different formats on the market, e.g. 19", ETSI, 23" (100 mm size)
Each module has 2 shelf-unit, each capable of handling :
- 24 splices of the fusion type with heat-shrink protection,
- 24 connectors.
The module is of the pivoting type, in order to optimise accessibilty while also allowing minimum movement of the pigtails and of the fibres when the module is opened. This enables the transient attenuation effect to be reduced to a minimum.
The module is made up of the following :
- A fixed chassis, attached to the structure;
- 2 individually pivoting shelf-unit mounted on one axis of rotation,
- Each shelf-unit is equipped with a maximum of 2 cassettes and with a frontal strip with two rows of connectors;
- Tube guide accessories for input/output of the retubed fibres, and/or pigtail-jumper guide accessories for front-panel output;
- A protective cover on the top module.
