Abstract
A bi-directional optical coupler is provided. The bi-directional optical coupler includes a package having a first side and a second side. A forward coupler and a reverse coupler are included in the package. The forward coupler receives DC electric signals at the first side of the package and transmits DC electric signals at the second side of the package. The reverse coupler receives DC electric signals at the second side of the package and transmits DC electric signals at the first side of the package. The inclusion of two couplers within a single package means that the two couplers are subject to the same temperatures and have similar degradation. For this reason, the two couplers remain matched in terms of efficiency.
