Abstract:
A telecommunications terminal block includes at least one contact module. The contact module features a front side and a rear side, an upper side and a lower side, a first side and a second side opposite the first side. Furthermore, the contact module features at least one row of contacts extending between the first side and the second side. The contacts are exposed at the front side. For another thing, the terminal block includes wire guides arranged at the upper side and/or lower side of the contact module. The wire guides lead cable conductors from (file front side to the first side or second side. The wire guides are grouped together into arrays, the wire guides of which each lead to a single side. At least two arrays, a first array and a second array, of wire guides, adjoin each other and at least one row of contacts of each contact module and are assigned to this row of contacts. The wire guides of each such array lead to opposite sides.

Abstract:
The invention refers to a telecommunications system comprising a module rack that defines a core bay, a service plane and a rack interface plane where the service plane is transverse to the rack interface plane. The core bay is in part bounded by the service plane and the rack interface plane. The telecommunications system also comprises a series of electronics modules each defining an electronics orientation plane where each of the modules includes two opposed cooling surfaces oriented substantially parallel to the electronics orientation plane. Each of the electronics modules is removably secured within the core bay. The series of the electronics modules forms an array such that their electronics orientation planes are substantially perpendicular to both the rack interface plane and the service plane. The array also defines at least one coolant stream passage across each cooling surface. Further the telecommunications system includes a coolant movement means for moving a coolant through the coolant stream passages and across the rack interface plane. As such, the coolant convects heat away from the cooling surfaces of electronics modules more efficiently and effectively than found in the prior art as it, amongst other things, shortens the distance over which the inlet coolant is required to travel to cool the same functional density and provides a coolant to the passage at approximately a uniform temperature for each module.
