HRE-500 Stub
The HRE has a 14 AWG, stranded ground wire and a four-pair, 20-foot
gel-filled stub for access to the doubler’s four ports. This 24 AWG stub has
foam skin insulation and a filled jacket. Each conductor has a dual insulation
consisting of an inner coating of natural, insulating-grade, high-density
cellular polyethylene covered by an outer skin of color-coded, high-density
solid polyethylene. Standard color codes allow for pair identification with
color compounds chosen for electrical balance and permanency. The
assembly is flooded with an Electro Thermo Plastic Rubber (ETPR)
compound, filling the air space between conductors.
A non-hygroscopic core wrap protects the core and provides improved
mechanical and electrical characteristics. The inner surface of the core wrap
is coated with the ETPR filling compound. The outer surface is coated with
an amorphous polypropylene compound. The cable core shield is a
corrugated copolymer-coated 8 mil aluminum tape. The outer jacket consists
of a black, low-density polyethylene material providing a flexible protective
covering that withstands exposure to sunlight, atmospheric temperatures,
ground chemicals and stresses expected in standard installations. The cable
complies with the requirements of ANSI/ICEA S-84-608-1994 and has an
outside diameter of 0.38 inches (10 mm).
The stub’s four pairs terminate on an internal assembly that contains the
card-edge connector and gas tube protector board. The stub pairs are routed
through a ferrite coil, which prevents EMI energy from exiting the stub pairs.
Figure 3 shows the identity of the four ports for each cable stub to provide
access. The CO ports connect to the upstream cable pair connections of either
another doubler or the line unit. The field ports connect to the downstream
cable pair connections of either another doubler or remote unit.

Ground Wire
The ground wire is required for both EMI and voltage surge protection for the
installed doubler.
End Cap
There are five compression bolts on the end cap which work to create a
waterproof barrier. When properly torqued, these bolts compress the
neoprene washer (shown in Figure 4) that sits between the enclosure’s two
end plates. The washer expands against the sides of the enclosure to form a
waterproof barrier. This allows the enclosure to be installed anywhere in the
network, including underground locations where it may be submerged in
water.
