Abstract
A two-path connection system for monomode optical fibers is applicable to conventional telecommunication systems for connecting subscriber lines. The connection system includes a cylindrical envelope having an internal precision chamber. Two ferrules are engaged in the internal precision chamber, each for receiving a monomode optical fiber for connection. A spacer is engaged in the internal precision chamber which is suitable for securing the two ferrules while precentering them inside the precision chamber.

A two-path connection system for connecting monomode optical fibers comprising:
- a first cylindrical envelope including a first internal precision chamber;
- two ferrules engaged in said first internal precision chamber, each for receiving a monomode optical fiber to be connected;
- a stationary cylindrical spacer engaged in said first internal precision chamber and being suitable for securing the two ferrules and precentering them inside the first internal precision chamber;
- a second cylindrical envelope including a second internal precision chamber in which the two ferrules are engaged;
- and
- a floating cylindrical spacer mounted in said second internal precision chamber, and suitable for securing the two ferrules, while still allowing them to be aligned.
A two-path connection system for connecting monomode optical fibers comprising:
- a first cylindrical envelope that is semirigid and closed, having a first internal circularly cylindrical precision chamber of diameter .phi..sub.1 ;
- two ferrules each having a same diameter d, engaged in said first internal precision chamber and each for receiving a monomode optical fiber to be connected;
- a first stationary cylindrical spacer having a diameter d.sub.1, engaged in said first internal precision chamber such that it comes tangentially into contact with said ferrules so as to secure them and precenter them inside the first chamber;
- a resilient second cylindrical envelope having a second internal circularly cylindrical precision chamber of diameter .phi..sub.2 identical to said diameter .phi..sub.1, in which the two ferrules are engaged;
- a second cylindrical spacer having a diameter d.sub.2 identical to said diameter d.sub.1, mounted at each end in a bracket external to said second envelope and suitable for rotating thereabout such that said second spacer comes tangentially into contact with said ferrules so as to secure them, while still allowing them to be aligned.
A two-path connection system for monomode optical fibers comprising:
- a first cylindrical envelope that is semirigid and closed, having a first internal circularly cylindrical precision chamber of diameter .phi..sub.1 ;
- two ferrules each having a same diameter d, engaged in said first internal precision chamber and each for receiving a monomode optical fiber to be connected;
- a first stationary cylindrical spacer having a diameter d.sub.1, engaged in said first internal precision chamber such that it comes tangentially into contact with said ferrules so as to secure them and precenter them inside the first chamber;
- a resilient second cylindrical envelope having a length 1 and including a second internal circularly cylindrical precision chamber of diameter .phi..sub.2 identical to said diameter .phi..sub.1 in which the two ferrules are engaged;
- a second floating cylindrical spacer having a length l.sub.1 that is not less than said length 1 and a diameter d.sub.2 identical to said diameter d.sub.1 of said first cylindrical spacer, the floating spacer being mounted at each end in a bracket external to said second envelope and suitable for rotating thereabout such that the floating spacer secures said ferrules while still aligning them.
A two-path connection system for monomode optical fibers, comprising:
- a first cylindrical envelope that is semirigid and closed, having a first internal circularly cylindrical precision chamber of diameter .phi..sub.1 ;
- two ferrules being of a same diameter d, engaged in said first precision chamber and emerging axially from said semirigid closed first cylindrical envelope, each ferrule for receiving a monomode optical fiber to be connected;
- a first stationary cylindrical spacer having a diameter d.sub.1, engaged in said first internal precision chamber such that it comes tangentially into contact with said ferrules so as to secure them and precenter them inside the first chamber;
- a resilient second cylindrical envelope having a length 1 and including a second internal circularly cylindrical precision chamber of diameter .phi..sub.2 identical to said diameter .phi..sub.1 in which the two ferrules are engaged;
- a second floating cylindrical spacer having a length l.sub.1 that is not less than said length 1 and a diameter d.sub.2 identical to said diameter d.sub.1 of said first cylindrical spacer, the floating spacer being mounted at each end in a bracket external to said second envelope and suitable for rotating thereabout such that the floating spacer secures said ferrules while still aligning them.
