Abstract: A fiber link recognition method, device, and system, to recognize different fiber links where the method includes sending, by a link recognition device, a first test optical signal, receiving a second test optical signal that is returned after the first test optical signal is sent to a connection port of a first optical node, acquiring a reflection peak of the second test optical signal on a fiber link, determining a port identifier of the connection port of the first optical node according to the reflection peak of the second test optical signal on the fiber link, and recognizing, the fiber link corresponding to the second test optical signal that is returned by the connection port of the first optical node. The method embodiment is used to recognize a fiber link.

Abstract: A receiver optical subassembly includes an optical receiving housing, and a first optical receiver, a second optical receiver, and a first glass are packaged in the optical receiving housing. The first glass is disposed obliquely relative to an optical receiving direction, and includes a light incident surface and a light emergent surface. The first optical receiver and the second optical receiver are opposite to the light emergent surface of the first glass. A first light splitting film is disposed on the light emergent surface of the first glass. A first reflective film is disposed on the light emergent surface of the first glass. The first light splitting film can transmit an optical signal of a first wavelength and reflect an optical signal of a second wavelength.
