FTTH Fiber Drop Cable—Indoor & Outdoor Application

---

As an access to providing high-speed
Internet speed, Fiber to the home (FTTH) has been highly favored in recent
years. It can achieve high-speed and long distance transmission, from a central
point directly to individual buildings such as residences, apartment buildings
and businesses through installation and use of optical fiber. FTTH drop cable
plays a prominent role during this process. So what is FTTH drop cable? And how
to install? This article would provide a satisfied answer for you.

 

About FTTH Drop Cable

FTTH drop cable contains 1 to 4
colored singlemode optical fibers with 250 µm individually, which
provides a good solution for fiber to the home last mile solution. The cable
contains two Fibre Reinforced Plastic (FRP) strength members and Low Smoke Zero
Halogen (LSZH) jacket with nominal dimension 2 x 3 mm. They are fully meet the
RoHS standards. With its small diameter, light weight and special structure, it
is easy to use, to handle and to pull the fibers out from the cables. It is an
ideal option for direct installation into the houses.

 

Features&Benefits

—Choice of fibre types

 

—Individually coloured optical fibres

 

—Notched 2 x 3 mm construction for easy
stripping

 

—Singlemode optical fibre meeting ITU-T
G.657A1 or ITU-T G.657A2 standard

 

How to Choose Right LSZH Jacket?

You can choose white LSZH jacket for
indoor use and black LSZH jacket for outdoor use within short distance. For the
white cables that are installed where they may be in direct sunlight for
extended periods of time will need to be replaced more often. So we need to
pick black LSZH jacket for they are UV-resistant.

 

Indoor And Outdoor Applications

There are mainly three applications of
FTTH drop cables: internal FTTH applications horizontal and riser, clipping to
surfaces including skirting boards, and short distance external use with black
LSZH jacket. Due to time and space limiting, this article would mainly
introduce the internal horizontal and riser cabling for FTTH applications,
which attach great importance to FTTH cabling.

 

Horizontal Cabling

Drop cable all dielectric for Fibre To
The Home (FTTH or FTTx) application, this means we need intrabuilding conduit.
Conduit can be made of metallic tubing or rigid polyvinyl-chloride plastic.
Conduit runs should be limited to 100 feet, with no more than two 90-degree
bends between pull points or boxes. It runs can be in ceilings or walls or
under floors.

 

To apply the FTTH fiber drop cable, we
need pull boxes. They are installed for fishing the run and looping the cable
for the next length of conduit. Pull boxes are not used for splicing cable.
Fish tapes or pull cords should always be placed in the conduit to ease
installation. Inner duct is an excellent tool for protecting cable and easing
future installations.

 

Riser Cabling

Drop optical fiber cables intended for
vertical applications have a calculated maximum vertical rise value assigned to
them. The vertical rise is the distance the cable may be pulled vertically
before being supported. It is determined by the weight of the cable and its
ability to resist buckling or kinking.

 

You can use split wire mesh grips to
pull cable vertically. The device works like basket or finger grips, supporting
the cable without crushing the core. Cables should be supported by cable ties,
straps or clamps in wiring closets. Whenever possible, begin the installation
from the top, allowing the weight of the cable to help the pull rather than
adding more load.

 

Conclusion

FTTH dramatically and unprecedentedly
increases the connection speeds available to computer users. FTTH drop optical
cable is a special cable that provide a perfect solution for FTTH transmission.
