A method of deploying a passive optical combiner that is a broad bandwidth spectral wavelength combiner for combining the outputs from multiples transmitter photonic integrated circuit chips and, thereafter, the amplification of the combined channel signals with a booster optical amplifier couple between the passive optical combiner and the fiber transmission link. The method comprises determining a torque output and an operating cost for operating the first and second electrical machines of the hybrid transmission effective to meet an operator torque request when the engine is operating in an engine-off operating state. A visual representation of the patient overlaid with an image of the intervention target, the instrument, and a path for guiding the instrument to perform said medical intervention is displayed in the stereoscopic guidance display. The metal shell includes a top wall and a bottom wall with a rectangular receiving space disposed therebetween for enclosing the first and the second tongue portions.
