Abstract
(EN)
Disclosed is an optical module (101) which is provided with: a casing (1); a first light outputting section (11), which is fixed to the casing (1) and generates first optical signals (L1); a second light outputting section (12), which is fixed to the casing (1) at an angle different from the angle at which the first light outputting section (11) is fixed, and which generates second optical signals (L2) having a wavelength different from that of the first optical signals (L1); a first branching filter (61), which refracts the first optical signals (L1) and/or the second optical signals (L2) such that the optical axis of the first optical signals (L1) and that of the second optical signals (L2) partially overlap each other; one isolator (80), which is disposed at a part where the optical axis of the first optical signals (L1) and that of the second optical signals (L2) overlap each other, and which performs isolation with respect to the first optical signals (L1) and the second optical signals (L2).
