1. A method of assembling an optical fiber assembly, wherein the optical fiber assembly includes a ferrule having a front end, a rear end, and a ferrule bore extending between the front and rear ends, the method comprising:
disposing a bonding agent into the ferrule;
wherein the bonding agent comprises an anaerobic adhesive;
wherein the bonding agent has a viscosity ranging between 50 cP and 7000 CP;
heating a front portion of the ferrule to at least 150° C. while the bonding agent is in the ferrule bore;
inserting an optical fiber into the ferrule bore;
wherein the heating step causes the bonding agent that is in the front portion of the ferrule to cure in less than 1 minute and thereby secure the optical fiber to the front portion of the ferrule.
