A fusion-bonded optical component is created using a laser oscillator for irradiating at least one beam of laser light upon optical components, for example an end of a rod lens and an end of an optical fiber. A head end provides for downstream transmission of telephony and control data in a first frequency bandwidth over the hybrid fibercoax distribution network and reception of upstream telephony and control data in a second frequency bandwidth over the hybrid fibercoax distribution network. The imaging device includes a photosensor that is configured entirely along the contours of the posterior focal plane of the imaging optical system. A first locking circuit is connected between comparable first points in the first and second plurality of amplifiers to ensure that the first points are oscillating in complementary fashion and a second locking circuit is connected between comparable second points in the first and second plurality of amplifiers to ensure that the second points are oscillating in complementary fashion. The controller is coupled to the plurality of pumps and controls power levels of the individual pumps, enabling control of fluid flow rate in the liquid cooling loop. The stator vane further has an adjustment member secured to the stator vane so that it covers the inlet.
