Abstract
This invention provides an optical module that enables to reduce an optical coupling loss when an external force is applied to an optical connector mating with the optical module. The present optical module comprises an optical sub-assembly and an optical receptacle having a cavity for receiving the optical connector and a space for receiving the optical sub-assembly. The optical sub-assembly provides a flange in its outer surface and the head portion thereof passes through the partition wall between the cavity and the space. Between the flange of the optical sub-assembly and the partition wall of the optical receptacle provides an O-ring, whereby the head portion of the optical sub-assembly enables to displace in the cavity and automatically recovers its original position.
Claims8
An optical module to be mated with an optical connector that includes an optical fiber, comprising:
- an optical sub-assembly having a head portion, said optical sub-assembly including an optical semiconductor device therein;
- an optical receptacle having a catty for receiving said optical connector and a space for receiving said optical sub-assembly, said optical receptacle having a groove with a front surface and a rear surface in an inner wall surface thereof, said rear surface being in direct contact with said flange of said optical sub-assembly;
- and
- an elastic member disposed between said front surface of said groove and said flange of said optical sub-assembly,
- wherein said elastic member enables said head portion of said optical sub-assembly to displace within said cavity.
An optical module to be mated with an optical connector that includes an optical fiber, comprising:
- an optical sub-assembly having a head portion, and a groove with a front groove surface and a rear groove surface in an outer surface thereof, said optical sub-assembly including an optical semiconductor device therein;
- an optical receptacle having a cavity for receiving said optical connector and a space for receiving said optical sub-assembly, said optical receptacle including a groove in an inner wall surface thereof;
- a bracket disposed in said groove of said optical receptacle and being in contact with said front groove surface of said optical sub-assembly;
- and
- an elastic member disposed between said rear groove surface of said optical subassembly and said bracket,
- wherein said elastic member enables said head portion of said optical sub-assembly to displace within said cavity.
