Function :
The BMX external distribution unit is used for the connection of subscriber wires to a multi-pair cable. The connection is made by means of SDP or SD2P protection modules. A partial distribution of the multi-pair cable can be realised by looping. The unit is fixed to the builidng by screws or to a pole with a metal hoop (not supplied). It is supplied with an earthing point.
Description :
The BMX external distribution unit for SDP-SD2P consists of a body, a cover and the connection modules.
The body consists of horizontal rails, module supports in the central part and cable entries in the lower part. A clamp device holds the multi-pair cables in position, and chicane feed sleeves hold the subscriber wires in places. An elastomer cable bushing with push down entries ensures the seal.
The cover is articulated and held in its open position.
The connection module
This clips on the rail. The IDC connection is secured by means of grease which ensures the seal for the connections between a pair of multi-pair cables and a Drop cable type subscriber wire.
The SD2P module is fitted with a triple-pole paraoverload protection. Tests can be carried out, either on the line side or the subscriber side, by means of a test module.
