Outside Telephone Cable

Foam-Skin, Filled, Direct Burial,
Aerial, Duct, BJFAF, BFASF*
RUS/RDUP Spec. PE-89
For direct burial or duct applications where protection from moisture is
required and aluminum shielding is desired. May also be used aerially if
attached to a support strand. BFASF is recommended for high-risk areas
where additional mechanical or rodent protection is required.
RUS/RDUP Designations:
BJFAF - BFCEA/BFASF - BFCEX
Electrical Characteristics
See Table C on page 22 in this section.
*BFASF cable may be subject to manufacturer minimums
and is available by request only. They have
the same core construction as BJFG except for the dual
shielding system: a corrugated, copolymer coated, .008
aluminum tape is applied directly over the core wrap. The
aluminum tape does not butt or overlap at any point along
the length of the cable. An outer shield of corrugated, copolymer
coated, .006 steel tape is applied directly over the
aluminum and overlaps. The shield interfaces are flooded.
Note: T-Screen? Type BJFAF cables may be available
with a core separated design for use with PCM-type
carrier equipment.

Conductors Solid annealed copper in 19, 22, 24 and 26 AWG.
Insulation Conductors are dual insulated with an inner layer of foamed, natural polyolefin covered
by an outer layer of solid, color-coded polyolefin.
Twisted Pairs Individual insulated conductors are twisted into pairs with varying lay lengths.
Core Assembly Cables of 25 pairs or less are assembled into a cylindrical core. Cables larger than 25
pairs are assembled into units, which are then used to assemble the core. Units are
individually identifiable by color coded unit binders.
Filling
Compound
The core assembly is filled with an 80
