To seal a cable junction, an insert is placed between two branch cables of the junction, which is then enclosed by a heat shrinkable envelope. The insert has at least one insert part having a block of heat fusible material attached by one or more flanges of heat conductive material to the branch cables. The block lies between the branch cables at least partially inside the envelope. Then, when the envelope is heated to cause it to shrink, the block fuses, thus forming a seal. For most sizes of branch cables, two insert parts may be used, but three or more may be used for large branch cables. The flange preferably has a tongue extending into the block to assist heat conduction.

An optical fiber distribution apparatus of the type in which optical feeder cables are connected to optical distribution cables through connectors. The optical fiber distribution apparatus includes a frame having a front portion; a plurality of distribution panels each having a free front edge; pivoting mechanisms for pivotally mounting respective distribution panels to the frame with regular vertical intervals for pivotable movement about a horizontal axis: and locking mechanisms for releasably locking each of the distribution panels selectively at one of both a normal position, where each distribution panel is parallel to the other with the free edge thereof positioned substantially not higher than the rotation axis thereof, and a raised position, where the free front edge of each distribution panel is raised above the rotation axis thereof for accessing to a distribution panel just below.
