Retains mounted on the opposite ends of the frame releasably engage the pan to hold it in position in the frame during shipping and storage and prior to mounting thereof. Also provided is an optical transmission system which employs the above-mentioned Raman amplifier and is suitable for transmitting multiplexed-wavelength signal light. The at least one bellows is connected between the first mass and the second mass and has an interior volume pressurized with a fluid to an internal fluid pressure which is greater than a zero-stiffness pressure such that the vibration attenuation device exhibits a negative lateral stiffness.
