Abstract: Methods of forming optical filament circuit patterns with planar and non-planar portions are provided. An optical filament circuit pattern is scribed by moving a filament guide and a substrate relative to one another at a speed between about 110 inches/minute and about 190 inches/minute, and dispensing an optical filament on, or in the vicinity of, a surface of the substrate. The filament or the substrate or both have adhesive surface(s). The adhesive surface is capable of being adhesively actuated by application of energy. Energy is applied simultaneous with, or subsequent to, scribing. Preferably, ultrasound energy is applied having an output power between about 2.0 watts and about 3.5 watts while applying a pressure to the filament between about 1.177 Newtons and about 1.324 Newtons. A portion of the filament circuit pattern is planar and another portion is non-planar. The non-planar portion traverses but does not contact or adhere to a pre-selected area of the substrate.

Abstract: A device includes a housing, two members protruding from the housing, two transmitting optical subassemblies, two receiving optical subassemblies, a multiplexer, and a de-multiplexer. The housing includes two ports for receiving optical fiber connectors. Functionally, the two members act as two standard sized transceivers.

The two members are attached to the housing in such a way so that when the device is plugged into the receptacle of the host device, the two members can translate in three directions and rotate in three directions relative to the housing.

Abstract: An adjustable strain relief boot includes a stationary portion and a moving portion slidably connected to the stationary portion. The adjustable strain relief boot is used to guide an optical fiber away from a connector of the optical fiber. In application, the stationary portion of the adjustable strain relief boot is press fitted onto to the connector.

The fixed angle of departure can be adjusted by the operator from a first position to a second position. The fixed angle of departure is adjustable between forty five and ninety degrees. In a locked position, the moving portion can not move relative to the stationary portion since actuator engagement teeth of an actuator arm of the stationary portion engage teeth of the moving portion.
