Abstract
An optical fiber holder is disclosed herein that includes at least one confinement slot for routing intermediate optical fibers within a housing of an optical assembly module, and preferably, a plurality of confinement slots for maintaining a target/nominal fiber bending radius for one or more intermediate optical fibers within the housing. Preferably, the optical fiber holder is disposed within the housing of an optical subassembly between an optical component, e.g., a TOSA arrangement and/or ROSA arrangement, and optical coupling receptacles, e.g., LC coupling receptacles, for optically coupling with external fibers for sending and/or receiving optical signals.

An optical module comprising:
- a housing having an optical coupling end for coupling to at least one optical fiber and an electrical coupling end for electrically coupling to external circuitry;
- at least first and second optical components disposed within the housing;
- an optical fiber holder disposed within the housing, the optical fiber holder defining at least first and second inner confinement slots and at least first and second outer confinement slots outside of the inner confinement slots, wherein the first inner confinement slot and the first outer confinement slot are located on a first side of a center line of the housing and the second inner confinement slot and the second outer confinement slot are located on a second side of the center line of the housing;
- at least first and second intermediate optical fibers disposed within the housing and optically coupled respectively to the first and second optical components;
- wherein the first intermediate optical fiber extends through the first inner confinement slot and the second outer confinement slot, and wherein the first inner confinement slot and the second outer confinement slot are spaced at a distance such that a bend formed along the first intermediate optical fiber is at or above a minimum bend radius associated with the first intermediate optical fiber;
- wherein the second intermediate optical fiber extends through the second inner confinement slot and the first outer confinement slot, and wherein the second inner confinement slot and the first outer confinement slot are spaced at a distance such that a bend formed along the second intermediate optical fiber is at or above a minimum bend radius associated with the second intermediate optical fiber;
- and
- wherein portions of the optical fiber holder extend above each of the first and second inner confinement slots and the first and second outer confinement slots to hold down the first and second intermediate optical fibers to maintain the first and second intermediate optical fibers in a portion of the housing.
