The present invention discloses an optical fiber connector, comprising: a housing, a ferrule installed within said housing; an end sleeve, connecting to the rear end of said housing; and an optical cable clamp, installed by insertion within said end sleeve, being provided for the purpose of clamping an optical cable. Said optical cable is secured within said optical cable clamp, and after said optical cable clamp is inserted and secured within said end sleeve, the optical fiber of said optical cable is inserted within said housing and butt-joined with the embedded optical fiber within said ferrule. As a result of this, before the butt-joined optical fibers are locked in, the optical cable has already been secured within the optical cable clamp and fixed to the connector housing. Therefore, the butt-joined optical fibers cannot be separated due to the effects of unexpected pulling force, thus ensuring the optical fiber of the optical cable reliably abuts the embedded optical fiber.
