Abstract
Abstract An optical fiber data link (14) between a missile (12) and a moving platform (10) launch site has a wound stack canister (16) on the platform and a second canister (18) that is aboard the missile. A first version of the platform canister (16) locates the wound stack (20) within an enclosure (26) with the fiber being payed out through an opening (28) in the enclosure which has a curved flared edge portion (30). In yet another version, the platform canister (32) is mounted within a gimbal (38) enabling the fiber payout direction to follow a path that does not result in damage to the fiber.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
89 words
An optical fiber data link for interconnecting a missile launched from a moving platform, comprising: a first dispensing canister mounted to the missile on which a first optical fiber end portion is formed into a stack; a second dispensing canister mounted to the moving platform including, a further stack formed from the opposite end portion of the fiber, and an enclosure having a single opening in the enclosure bottom with enclosure walls defining the opening being flared outwardly forming smooth curved surfaces facing the fiber dispensed through the opening.
Claim 2
Dependent Claim
89 words
An optical fiber data link for interconnecting a missile launched from a moving platform, comprising: a first dispensing canister mounted to the missile on which a first optical fiber end portion is formed into a stack; a second dispensing canister mounted to the moving platform including, a further stack formed from the opposite end portion of the fiber, and an enclosure having a single opening in the enclosure bottom with enclosure walls defining the opening being flared outwardly forming smooth curved surfaces facing the fiber dispensed through the opening.
Claim 3
Dependent Claim
22 words
An optical fiber data link as in claim 1, in which the enclosure and further stack are fixedly mounted to the aircraft.
Claim 4
Dependent Claim
36 words
An optical fiber data link as in claim 1, in which the further stack and enclosure are each generally cylindrical, the cylindrical axes of both being arranged substantially normal to the moving platform direction of movement.
Claim 5
Dependent Claim
83 words
Optical fiber dispensing apparatus for use on a moving platform to form a missile data link, comprising: a drum on which a length of the optical fiber is wound in a stack; a hollow generally cylindrical enclosure within which the drum and wound stack are mounted, said enclosure having an opening through which the fiber passes on payout; and gimbal means mounting the enclosure to the moving platform for providing the ability to reorient the enclosure and drum throughout a substantial solid angle.
Claim 6
Dependent Claim
83 words
Optical fiber dispensing apparatus for use on a moving platform to form a missile data link, comprising: a drum on which a length of the optical fiber is wound in a stack; a hollow generally cylindrical enclosure within which the drum and wound stack are mounted, said enclosure having an opening through which the fiber passes on payout; and gimbal means mounting the enclosure to the moving platform for providing the ability to reorient the enclosure and drum throughout a substantial solid angle.
Claim 7
Dependent Claim
25 words
Optical fiber dispensing apparatus as in claim 4, in which a substantial loop of fiber is formed outwardly of the enclosure prior to missile launch.
Claim 8
Dependent Claim
32 words
Optical fiber dispensing apparatus as in claim 4, in which the enclosure opening through which the fiber passes on payout faces in a direction opposite to that of the missile launch direction.
Claim 9
Dependent Claim
100 words
An optical fiber data link for a helicopter launched missile, comprising: a dispensing canister aboard the missile on which a first optical fiber end portion is wound into a stack; a further dispensing canister carried by the helicopter including, a drum on which an opposiste end portion of the optical fiber is wound; a hollow generally cylindrical enclosure within which the fiber wound drum is mounted, said enclosure having an opening through which the fiber passes on payout; and a gimbal mounting for the enclosure providing the ability to reorient the enclosure and wound drum throughout a substantial solid angle.
Claim 10
Dependent Claim
100 words
An optical fiber data link for a helicopter launched missile, comprising: a dispensing canister aboard the missile on which a first optical fiber end portion is wound into a stack; a further dispensing canister carried by the helicopter including, a drum on which an opposiste end portion of the optical fiber is wound; a hollow generally cylindrical enclosure within which the fiber wound drum is mounted, said enclosure having an opening through which the fiber passes on payout; and a gimbal mounting for the enclosure providing the ability to reorient the enclosure and wound drum throughout a substantial solid angle.
Claim 11
Dependent Claim
25 words
Optical fiber data link as in claim 7, in which a substantial loop of fiber is formed outwardly of the enclosure prior to missile launch.
Claim 12
Dependent Claim
32 words
Optical fiber data link as in claim 7, in which the enclosure opening through which the fiber passes on payout faces in a direction opposite to that of the missile launch direction.
