In a described embodiment, a fiber optic connection system for use in a subterranean well includes two assemblies, each having a fiber optic connector. A biasing device applies a biasing force which maintains the fiber optic connectors operatively connected to each other while the assemblies are secured to each other in the well. ## Claims ### Claim 1 A fiber optic connection system for use in a subterranean well, the system comprising: a first assembly having a first fiber optic connector; a second assembly having a second fiber optic connector; and a biasing device applying a biasing force which maintains the first and second fiber optic connectors operatively connected to each other, wherein the first assembly includes a seal assembly which sealingly engages the second assembly as the first and second assemblies are engaged with each other, the seal assembly being rotatable relative to the first fiber optic connector. ### Claim 2 (depends on 1) The system of claim 1, wherein relative displacement is permitted between the first and second assemblies while the first and second assemblies are engaged with each other in the well and while the first and second fiber optic connectors remain operatively connected to each other. ### Claim 3 (depends on 1) The system of claim 1, wherein the biasing force maintains the first and second fiber optic connectors operatively connected to each other during relative displacement between the first and second assemblies. ### Claim 4 (depends on 1) The system of claim 1, wherein the first and second fiber optic connectors are operatively connected to each other prior to the first and second assemblies being latched to each other. ### Claim 5 (depends on 1) The system of claim 1, wherein the first and second fiber optic connectors are operatively disconnected from each other prior to the first and second assemblies being unlatched from each other. ### Claim 6 (depends on 1) The system of claim 1, wherein the biasing force increases after the first and second fiber optic connectors are operatively connected to each other, the biasing force increasing as the first and second assemblies are latched to each other. ### Claim 7 (depends on 1) The system of claim 1, wherein the biasing force is removed from the first and second fiber optic connectors prior to the first and second assemblies being unlatched from each other. ### Claim 8 (depends on 1) The system of claim 1, wherein an alignment surface aligns the first and second fiber optic connectors by rotating the first fiber optic connector relative to the seal assembly of the first assembly while the seal assembly is engaged with the second assembly. ### Claim 9 (depends on 1) The system of claim 1, wherein the first assembly is connected at an end of a first tubular string, a longitudinal flow passage of the first tubular string extending through the first assembly, wherein the second assembly is connected at an end of a second tubular string, a longitudinal flow passage of the second tubular string extending through the second assembly, and wherein the first and second tubular string flow passages are in sealed communication with each other when the first and second assemblies are latched together. ### Claim 10 A fiber optic connection system for use in a subterranean well, the system comprising: a first assembly having a first fiber optic connector; a second assembly having a second fiber optic connector; the first and second fiber optic connectors remaining operatively connected to each other during limited relative displacement between the first and second assemblies, and the first fiber optic connector operatively disconnecting from the second fiber optic connector prior to the first assembly unlatching from the second assembly. ### Claim 11 (depends on 10) The system of claim 10, further comprising a biasing device which applies a biasing force to maintain the first and second fiber optic connectors operatively connected to each other during the limited relative displacement between the first and second assemblies. ### Claim 12 (depends on 11) The system of claim 11, wherein the biasing force is applied to operatively connect the first and second fiber optic connectors prior to the first and second assemblies being latched to each other. ### Claim 13 (depends on 11) The system of claim 11, wherein the biasing force ceases to maintain the first and second fiber optic connectors operatively connected to each other prior to disengaging the first and second connectors from each other. ### Claim 14 (depends on 11) The system of claim 11, wherein the biasing force increases after the first and second fiber optic connectors are operatively connected to each other, the biasing force increasing as the first and second assemblies are latched to each other. ### Claim 15 (depends on 11) The system of claim 11, wherein the biasing force is removed from the first and second fiber optic connectors prior to the first and second assemblies being unlatched from each other. ### Claim 16 (depends on 10) The system of claim 10, wherein the first and second fiber optic connectors are operatively connected to each other prior to the first and second assemblies being latched to each other. ### Claim 17 (depends on 10) The system of claim 10, wherein the first assembly includes a seal assembly which sealingly engages the second assembly as the first and second assemblies are engaged with each other, the seal assembly being rotatable relative to the first fiber optic connector. ### Claim 18 (depends on 10) The system of claim 10, wherein an alignment device aligns the first and second fiber optic connectors by rotating the first fiber optic connector relative to a seal assembly of the first assembly while the seal assembly is engaged with the second assembly. ### Claim 19 (depends on 10) The system of claim 10, wherein the first assembly is connected at an end of a first tubular string, a longitudinal flow passage of the first tubular string extending through the first assembly, wherein the second assembly is connected at an end of a second tubular string, a longitudinal flow passage of the second tubular string extending through the second assembly, and wherein the first and second tubular string flow passages are in sealed communication with each other when the first and second assemblies are latched together.
