Abstract
A rigid, low expansion formable housing composition can be used to package optical waveguide couplers. The housing is in intimate contact with and strongly bonded to the coupler being packaged. The housing composition includes a formable polymeric resin, a glass-ceramic or ceramic or glass filler, and, optionally, strengthening fibers. The filler has a low thermal expansion to compensate for the high expansion of the resin. A moisture barrier layer may be placed around the housing composition, and it is possible to incorporate a shock absorbing material between the housing and the moisture barrier layer.
