Claim 0:
1. A receiver optical sub-assembly comprising:
a first demultiplexer disposed on a direction in which light enters the receiver optical sub-assembly and configured to:
transmit a first optical signal of a first wavelength through a body of the first demultiplexer; and
reflect a second optical signal of a second wavelength from a surface of the first demultiplexer;

a first optical receiver disposed on a transmission optical path of the first demultiplexer and configured to receive the first optical signal of the first wavelength;
an optical lens combination disposed on a reflection optical path of the first demultiplexer and configured to:
receive the second optical signal of the second wavelength reflected by the first demultiplexer; and
guide the second optical signal of the second wavelength;

a second optical receiver configured to receive the second optical signal of the second wavelength from the optical lens combination;
a header; and
a cap disposed on the header,
wherein the first demultiplexer, the first optical receiver, the second optical receiver, and the optical lens combination are disposed inside the cap, and
wherein the first optical receiver and the second optical receiver are coupled to the header.
