Opposite ends ( ) of the GRIN lens protrude from opposite ends of the sleeve. The outer tube includes first and second receiving portions ( ). The ferrule is glued into the first receiving portion, and the sleeve is secured in the second receiving portion. A plurality of soldering holes ( ) is defined in a periphery of the outer tube. Soldering is applied to the sleeve through the holes to firmly connect the outer tube and the sleeve together. A position of the GRIN lens relative to the optical fiber can be easily readjusted by re-soldering the sleeve.
