Abstract
A junction box for linking a first optical communications cord with two or more second optical communications cords, includes a sealable, flat housing having internal formations for organizing optical fibres; terminals, preferably glands, along one edge of the housing for connection to the first and/or second optical communications cords; passive optical components including a 1.times.2 fiber-optic coupler all interconnected by internal optical fibres with the terminals, the internal fibres all being organized together in a single loop parallel to the major faces of the housing; and clamps along the inside of at least one different edge of the housing between the loop and the edge wall of the housing, retaining the passive optical components.
