Abstract
Abstract A fiber protector which cooperates with the applied connector to house and protect the extending length of glass fiber of a fiber optic cable. The protector is a cylinder having a first end coupled to the connector. The protector is elongated to receive the extending length of glass fiber and is sufficiently rigid to protect the extending length of glass fiber from the application of force which could cause cracking or breakage of the glass fiber. Additionally, the protector may be formed of a material having thermal conductivity properties which aid in the thermal curing of the resin within the connector ferrule. Heat is then conducted by the protector to the connector body, and thus to the resin within the ferrule. Furthermore, an apparatus may be provided for connection to the heating end of a standard heat gun, and include means for receiving at least one protector to provide thermal communication between the heat gun and the protector. The heat from the heat gun will thus be applied to the protector, and conducted to the body of the connector and thus the resin.

Claim 2
Dependent Claim
105 words
A protector for use with a fiber optic cable at least partially terminated by a connector and having a length of bare fiber extending outwardly from the connector, said protector comprising: an elongated, at least substantially self supporting body having a first end and a second end and defining a cavity therethrough adapted to fully receive the length of bare fiber; and means associated with said body for substantially rigidly, yet releasably, fixing said first end of said body to the connector with said second end of said body extending outwardly from the connector and the length of bare fiber fully received within said cavity.
Claim 3
Dependent Claim
33 words
A protector as in claim 1, wherein said means comprises exterior threads on said first end of said body adapted to operatively engage with interior threads on a coupling nut of the connector.
Claim 4
Dependent Claim
16 words
A protector as in claim 2, wherein said body is in the form of a cylinder.
Claim 5
Dependent Claim
62 words
A protector as in claim 1, wherein said means comprises a pair of projecting lugs extending radially outwardly from said body adjacent said first end and a pair of receiving grooves communicating with said first end of said body, said lugs and grooves adapted to operatively engage with detent grooves and connector lugs, respectively, on a bayonet coupling nut of the connector.
Claim 6
Dependent Claim
16 words
A protector as in claim 4, wherein said body is in the form of a cylinder.
Claim 7
Dependent Claim
94 words
