First Claim
1. A connector-attached optical fiber cord comprising:
- an optical fiber cord comprising a coated optical fiber and a sheath surrounding a circumference of the coated optical fiber;
a ferrule attached to a front end of the coated optical fiber;
a housing that houses the ferrule and the optical fiber cord such that the ferrule is exposed to an exterior of the housing at a front end of the housing while the optical fiber cord extends out of a rear end of the housing;
a protective tube attached to a portion of the optical fiber cord in which the coated optical fiber is exposed; and
a boot attached to the rear end of the housing and through which the portion of the optical fiber cord is inserted, whereinthe protective tube comprises;
a tube body having a uniform outside diameter; and
