Abstract
The optical fiber connector includes a connector housing (), having a splice assembly () therein, and an end cap () attached to one end of the connector housing (), from which leads out a primary coating portion (). A boundary () between a portion of the primary coating portion (), obtained by removing an outer coating () of the inner cover () while leaving an inner coating (), and a portion obtained by leaving the outer coating () of the inner cover (), is located in the interior of the connector housing (). The end cap () is provided in the interior thereof with a tubular portion and an extension extending from an end of the tubular portion, the tubular portion including an insert hole for an insertion of the primary coating portion () approximately coaxially with a guiding hole formed in the splice assembly accommodated in the connector housing () for guiding the primary coating portion () leading out from the splice assembly. The extension includes a strain-control hole, communicating with the insert hole, for receiving said boundary () of the primary coating portion (), and for controlling stress at the boundary ().
