at least one epoxy injection port for receiving epoxy to secure optical fibers routed through the fiber holder; and
a main channel that extends between the first and second ends of the main holder body and includes a fiber anchoring region adjacent the second end of the main holder body, wherein the fiber anchoring region includes a non-grooved section for receiving coated portions of a plurality of optical fibers and a grooved section that extends from the non-grooved section to a cross-channel that functions as an epoxy stop.
11. The fiber holder of claim 10 , wherein the first and second side walls each include a precision rail.
12. The fiber holder of claim 10 , further comprising a cover, wherein the at least one epoxy injection port is defined in the cover of the fiber holder.
13. The fiber holder of claim 12 , wherein the cover is retained in the main holder body by a snap-fit connection or a press-fit connection.
14. The fiber holder of claim 12 , wherein the at least one epoxy injection port has a chamfered outer surface at a top side of the cover.
15. The fiber holder of claim 12 , wherein an extended recess is provided at a bottom side of the cover, the extended recess extending across a width of the cover and surrounding the at least one epoxy injection port to encourage the flow of epoxy.
16. A fiber holder for holding optical fibers, the fiber holder comprising:
a main holder body having a length that extends between first and second ends of the main holder body, a width that extends between first and second side walls of the main holder body, and a height that extends between top and bottom sides of the main holder body, wherein the first and second side walls of the main holder body each define a wedge receiving slot that has a tapered interior surface;
the main holder body defining a plurality of fiber positioning grooves that extend along the length of the main holder body and are spaced across the width of the main holder body, wherein stand-off portions are located between the plurality of fiber positioning grooves; and
a cover including wedges on opposing sides thereof, the wedges having a tapered surface, wherein, when the cover is moved longitudinally into a main channel, the tapered surface of the wedges are configured to cooperate with the tapered interior surface of the main holder body to cause the cover to ramp downward against the stand-off portions to clamp the optical fibers routed within the plurality of fiber positioning grooves.
