A telecommunications electric circuit having a low return loss and low crosstalk is adapted for use with unshielded twisted pairs of connecting wires. The circuit includes a pair of elongated circuit conductors parallel to each other over a substantial portion of their respective lengths. Each circuit conductor being a trace having a uniform width over a substantial portion of the length of the trace. Each circuit conductor trace having a width equal to the width of the other trace of the pair. Each of the circuit conductor traces has a uniform thickness. The circuit conductor traces are spaced apart a uniform distance which distance is determined from the center of each trace to the center of the other trace. The uniform distance being no greater than twice the width of one of said traces. A compensation trace is spaced from, parallel to and aligned with a portion of each of the respective circuit conductors.

A terminal assembly includes a block and a plurality of clip-type terminals mounted to the block. The block is a dielectric body having a central section and fanning strip sections at opposed margins. The terminals are loosely received through the holes and have wire receiving portions on one side of the central section and lying intermediate the fanning-strip sections and base portions on the opposite side of the central section. A retaining plate engages with the body for enclosing the base portions of the terminals within the dielectric body. The retaining plate further has a plurality of elongate, parallel and spaced-apart raised rib portions arranged for engaging the base portions of the terminals, such that wire receiving portions thereof are held in position projecting through the holes. The terminals comprise clip terminals having a flat body that includes two opposed resilent arms cantilevered from the base of the terminal. The resilient arms are separated by a notch at an upper end for receiving a wire conductor, by a conductor-receiving slot that extends downwardly from a lower end of the notch, and by an enlarged aperture extending downwardly from a lower end of the slot to the base. Oppositely outwardly facing edges of the resilient arms extend downwardly at a divergent angle to the base and inwardly facing edges of the resilient arms defining the aperture diverge at a substantially identical angle, such that the portions of the resilient arm flanking the aperture are of constant width.

Apparatus and method for storing the spliced end sections of optical fibers comprises a tray having a first and second series of channels each for receiving an optical fiber, the first series being spaced from the second series by a gap, a splice block releasably mounted in the gap, the splice block also having a series of channels that substantially span the gap whereby the respective channels of the first series are connected to the corresponding channels of the second series by the channels in the splice block. A tray is used for each group of fibers (one group from each cable) spliced together respectively to connect the cables together. The optical fibers from a first cable are spliced to the corresponding optical fibers in a second cable, the splices being mounted on the splice block. The tray constitutes a means for storing the buffer tubing that is wound up on the tray. A receptacle is provided with a plurality of tray mounting cavities for storage and individual retrieval of each of the trays.
