Claim 10

In a fiber optic contact which comprises a fiber optic cable having a first free end, and a sleeve member surrounding said first free end and proportioned to support said free end in abutting relation with the free end of another fiber optic cable for optical transmission between them, the improvement comprising, in combination: said sleeve member carrying a spacing sleeve, said spacing sleeve surrounding said first free end, said sleeve member defining first means for engaging an end of said spacing sleeve to limit the advancement of said sleeve member relative to said spacing sleeve.

Claim 11

The contact of claim 8 in which a second fiber optic contact defines fiber optic cable having a second free end positioned in said abutting relation with the first free end of said fiber optic cable within said spacing sleeve, said second fiber optic contact defining second means engaging another end of said spacing sleeve, said spacing sleeve being proportioned so that as said first and second means abut opposed ends of said spacing sleeve, the first and second free ends also abut each other.

Claim 12

The contact of claim 9 in which the first and second free ends are stripped of insulation which is carried by other portions of said fiber optic cables.

Claim 13

The contact of claim 10 in which one of said sleeve members carry outer sleeve means secured at one end to said sleeve member and surrounding and enclosing the abutting free ends of said fiber optic cable, said outer sleeve means carrying said inner spacing sleeve in its bore.

Claim 14

The contact of claim 9 in which said sleeve member carries outer sleeve means secured at one end to said sleeve member and surrounding and enclosing the free end of said fiber optic cable, said outer sleeve means carrying in its bore said inner spacing sleeve.

Claim 15

The contact of claim 12 in which spring means urge said sleeve members of said contacts against the inner spacing sleeve.

Claim 16

The contact of claim 8 in which spring means urges said sleeve member against the spacing sleeve.

Claim 17

In a fiber optic contact which comprises a first fiber optic cable having a first free end, and a sleeve member surrounding said first free end and proportioned to support said free end in abutting relation with the free end of another fiber optic cable for optical transmission between them, and a second fiber optic contact defining a second fiber optic cable having a second free end positioned in said abutting relation with the first free end of said fiber optic cable, the improvement comprising ,in combination: a collet slidably mounted on the sleeve member of said first fiber optic cable; compression spring means carried on said sleeve member between said collet and said first free end, whereby said contact may be retained in said abutting relation by retention means that engages said collet in a position to bias said free end toward said second fiber optic cable free end through the spring means, said sleeve member carrying an inner spacing sleeve, said spacing sleeve surrounding said abutting first and second free ends, said sleeve member defining first means for engaging an end of said spacing sleeve to limit the advancement of said sleeve member relative to said spacing sleeve, said second fiber optic contact defining second means engaging another end of said spacing sleeve, said spacing sleeve being proportioned so that as said first and second means abut opposed ends of said spacing sleeve, the first and second free ends also abut each other, said sleeve member also carrying outer sleeve means secured at one end to said sleeve member and surrounding and enclosing said abutting first and second free ends, said outer sleeve means carrying in its bore said inner spacing sleeve.

Claim 18

In a fiber optic contact which comprises a first fiber optic cable having a first free end, and a sleeve member surrounding said first free end and proportioned to support said free end in abutting relation with the free end of another fiber optic cable for optical transmission between them, and a second fiber optic contact defining a second fiber optic cable having a second free end positioned in said abutting relation with the first free end of said fiber optic cable, the improvement comprising ,in combination: a collet slidably mounted on the sleeve member of said first fiber optic cable; compression spring means carried on said sleeve member between said collet and said first free end, whereby said contact may be retained in said abutting relation by retention means that engages said collet in a position to bias said free end toward said second fiber optic cable free end through the spring means, said sleeve member carrying an inner spacing sleeve, said spacing sleeve surrounding said abutting first and second free ends, said sleeve member defining first means for engaging an end of said spacing sleeve to limit the advancement of said sleeve member relative to said spacing sleeve, said second fiber optic contact defining second means engaging another end of said spacing sleeve, said spacing sleeve being proportioned so that as said first and second means abut opposed ends of said spacing sleeve, the first and second free ends also abut each other, said sleeve member also carrying outer sleeve means secured at one end to said sleeve member and surrounding and enclosing said abutting first and second free ends, said outer sleeve means carrying in its bore said inner spacing sleeve.

Claim 19

The contact of claim 15 in which the first and second free ends are stripped of insulation which is carried by other portions of said fiber optic cables.

Claim 20

The contact of claim 16 in which the spring means urges said sleeve member against the inner spacing sleeve.

Claim 21

The contact of claim 17 in which said second fiber optic contact also defines a second sleeve member surrounding said second free end, said second sleeve member being proportioned to support said second free end in abutting relation with the first free end, said second sleeve member carrying a second collet, and second compression spring means carried on said second sleeve member between said collet and said second free end, whereby said contact may be retained in said abutting relation between the first and second free ends by retention means that engages said second collet in a position to bias said second free end toward the first free end through the second spring means.
