Splice arrangements for optical fibre cables

A cable locking and sealing device has an elongate body of elastomeric material formed with at least one through-passage for receiving a cable and at least one longitudinal slit extending down at least a portion of its length. The interior of the through passage is formed with a series of annular ribs which each taper in depth towards a point adjacent the longitudinal slit. When the device is pulled into an entry port, its elongate body becomes radially compressed thereby holding the cable firmly in place: however, the sealing effect of the ribs against the cable is not compromised by any relative longitudinal displacement of the portions of the body either side of the slit.

Cable sealing and locking device

An enclosure assembly for optical fibre splices or other optical fibre components comprises a plurality of trays disposed in a stack with the trays inclined at a common angle to a longitudinal axis of the stack. Each tray is of generally elliptical shape in plan and is pivotally mounted, adjacent one end of its major axis, to an upright support.
