LG 250 SEALED FIBER OPTIC SPLICE
CLOSURE
1.0
GENERAL
1.01 The LG 250 Sealed Fiber Optic Splice Closure
provides a unique, flexible fiber splicing system
for Fiber-in-the-Loop or distribution splicing.
Typical types of cables that can be used in this
closure are: central core shielded, central core
dielectric, loose tube shielded, loose tube
dielectric, ribbon shielded, ribbon dielectric.
Also, the closure incorporated a unique cable
clamp design that secures the cable and allows
the dome and C-Half sections to be removed
with out disturbing previously installed cables.
The
LG-250
consists
components. Refer to Figure 1.
1.02 Dome: Protects all internal components.
1.03 C-Half Section: Creates end sealing surface with
center section. Each C-Half section comes with
four (4) hex head bolts for securing for securing
to center section.
1.04 Center Section: Center section consists of five
(5) cable sheath strain relief and central strength
member tie-downs and will accommodate four (4)
LL-2400, two (2) LL-4848 or four (4) LL-4800
splice trays. The Express side incorporates as
storage tray and clear cover for bare or ribbon
fiber. Included and installed in the Center Section
are five (5) sealing port grommet sets. The
Express side of the closure has two (2) and the
Drop/Lateral side has three (3) ports.
1.05 O-Ring: Provides sealing between dome and the
center section assembly.
1.06 V-Band: Provides locking and final clamping
between the dome and center section assembly.

4.0 CABLE PREPARATION
CAUTION: When preparing cable, insure that buffer
tubes and fibers are NOT cut, nicked or kinked. If this
occurs, cut back to eliminate damaged area.
4.01 Express Cables: Remove 66" of cable sheath
and expose buffer tubes, removing shield, Mylar
or Kevlar if present.
Drop (Stub) Cables: Remove 72" of cable
sheath.
(See
measurements).
4.02 Remove all cable coating compounds. Clean
sheath, all primary tubes and dielectric strands
