Description / Abstract:


The object of this Specification is to prescribe preferred ratings and characteristics for pressurized aerial, buried or underground fiber optic splice closures; select from EIA-5150i300, "Generic Specification for Optical Fiber and Cable Splices," the appropriate quality assessment procedures, tests, and measuring methods; and to give general performance requirements for this type splice closure. This Sectional Specification must be used in conjunction with a fiber splice sectional to specify a complete optical cable splice. The Specification addresses those requirements necessary to provide external protection for an optical fiber splice, but does not cover the properties of a fiber-to-fiber splice.

Closure Types

This Sectional Specification identifies the characteristics of pressure-tight fiber optic cable splice closures designed for use with fiber optic cables in underground, buried, and aerial telecommunications applications. Moisture access into the cable closure will generally be excluded by means of a positive gas pressure system, normally not exceeding 70 kilopascals (10 pounds per square inch).

Closure Classifications

Splice closures are classified according to the configuration in which cables may enter the ends of the closure as follows:

Straight Splice Closure: Closures that provide openings for only one cable to enter each end of the closure.

Branch Splice Closures: Closures that provide openings for two or more cables to enter one or both ends of the closure.

Butt Splice Closures: Closures that provide openings such that two or more cables enter one end of the closure and no cable enters the other end of the closure.
