Arrangement and method for terminating a line in a subsea environment

A fiber termination arrangement for terminating an optical line in a subsea environment, the optical line including an outer sheath and a tube disposed within the outer sheath, the fiber termination arrangement comprising:

• an outer housing (202) having a first end, a second end, and an opening that extends in an axial direction between the first end and the second end;
• a sheath seal (302) having a first groove (502) and a second groove (502), the sheath seal (302) positioned within the opening, the sheath seal (302) including:
• a first sheath seal member (404) having a first contact surface arranged to sealingly engage the outer sheath (104), and a first head member (606) sealingly positioned within the first groove;
• and
• a second sheath seal member (410) having a second contact surface arranged to sealingly engage the outer sheath (104), and a second head member (606) sealingly positioned within the second groove;
• a tube seal (304) positioned within the opening, the tube seal (304) including:
• a first tube seal member (1004) having a first tube seal surface (1206) arranged to sealingly engage the tube (110);
• and
• a second tube seal member (1012) having a second tube seal surface (1206) arranged to sealingly engage the tube (110);
• a sheath end cap (206) coupled to a first end of the outer housing (202) to inhibit movement of the sheath seal (302) in the axial direction, the sheath end cap (206) including a first aperture sized to allow passage of the outer sheath (104);
• and
• a tube end cap (208) coupled to a second end of the outer housing (202) to inhibit movement of the tube seal (304) in the axial direction, the tube end cap (208) including a second aperture sized to inhibit passage of components larger than the tube (110).
