Patent ID: 8463132

Claim:
An optical device for transmitting and receiving optical signals over optical media, the optical device comprising a housing having: a first optical subassembly comprising: a first substrate; a first photodiode component disposed atop the first substrate, the first photodiode component configured to convert an optical signal received via the optical media and having the first wavelength; a first optical filter disposed atop the first photodiode component, the first optical filter configured to allow the transmission therethrough of optical signals having the first wavelength; and a first optical transmitter component disposed atop the first optical filter, wherein the first optical transmitter is configured to emit an optical signal having a second wavelength for transmission along the optical media; a second optical subassembly comprising: a second substrate separate from the first substrate; a second optical transmitter component disposed atop the second substrate, wherein the second optical transmitter is configured to emit an optical signal having the first wavelength for transmission along the optical media; a second optical filter disposed atop the second optical transmitter component, the second optical filter configured to allow transmission therethrough of optical signals having the first wavelength; and a second photodiode component disposed atop the second optical filter, the second photodiode component configured to convert an optical signal received via the optical media and having the second wavelength.
