    Abstract: An optical signal routing device may include a first lens, second lens and a wavelength division multiplexer (“WDM”) filter positioned between the first and second lenses. The WDM filter may reflect a signal of a first wavelength with a first attenuation and pass the first wavelength signal attenuated by at most a second attenuation to the second lens, the first attenuation exceeding the second attenuation by a first predetermined amount. The WDM filter may reflect a signal of a second wavelength different than the first wavelength with at most a third attenuation, the first attenuation exceeding the third attenuation by at least a second predetermined amount. The device may further include a reflector positioned to reflect the first wavelength signal reflected by the WDM filter toward the WDM filter with at least a fourth attenuation, the fourth attenuation exceeding the second attenuation by at least a third predetermined amount.
