Abstract:
1. A multi-channel optical signal assembly, comprising: a first filter at a first angle relative to an incident optical signal and configured to reflect light in the incident optical signal having a first wavelength, provide a first reflected optical signal, and allow light in the incident optical signal having at least a second wavelength to pass through the first filter, wherein the first angle is 13°±3°; a first mirror at a second angle relative to the first reflected optical signal and configured to further reflect the first reflected optical signal and provide a second reflected optical signal; a first lens configured to focus and/or collimate the second reflected optical signal and provide a focused optical signal; a first receiver coupled to the first lens and configured to receive the focused optical signal; a second filter configured to receive the light in the incident optical signal having at least the second wavelength and reflect a portion of the light in the incident optical signal having the second wavelength at a same first angle as the first filter; a second mirror configured to further reflect the reflected portion of the light in the incident optical signal having the second wavelength at a same second angle as the first mirror to a second receiver; a second lens configured to focus and/or collimate the further reflected portion of the light in the incident optical signal having the second wavelength; and a second receiver coupled to the second lens and configured to receive the focused and/or collimated further reflected portion of the light in the incident optical signal.
