INSTALLING FIBER CABLES

Bends in Fiber cables

Plastic and glass filament fiber cables may be bent to avoid

obstacles on the way to the sensing site. Here are some

guidelines about the location of cable bends: The first bend must

be as least 20 mm (0.79 in) away from where the cables enter

the amplifier. The last bend must be at least 20 mm (0.79 in)

bending the sensing head. We recommend a 25 mm (1.0 in)

minimum radius for a right angle bend to maintain the rated

sensing distance. The sharpest allowable right angle bend is over

a 10 mm (0.39 in) radius, but this will result in a shorter sensing

distance. Refer to the bending radius graph.

Do not apply excess force on the Fiber Units.

Do not pull or press the Fiber Units. The Fiber Units have a

withstand force of 1 kg or 3 kg (pay utmost attention because the

fibers are thin).

Do not bend the Fiber Units beyond the permissible bending

radius.

Do not bend the edge of the Fiber Units.

Proper Supports for Cables

To support the fiber cable between the sensing site and the

amplifier, mount the cable using a nylon strap or cable tie. Do not

use a U-shaped strap that will compress or put stress on the fiber

cable. To prevent damage from excessive vibration, take up the

fiber in a loop as shown below.

The Fiber Head could be broken by excessive vibration. To

prevent this, the following is effective:

A one-turn loop can

absorb vibrations.

Appearance

The length can be ordered in increments of 1 m between

6 m min. and 20 m max. (2-m and 5-m fiber length types are

standard for E32-TC200, E32-DC200.)

E39-F10 Fiber Connector

Use the following procedure (refer to the figure) to connect fibers

via the Fiber Connector.

Splice

Retention Unit

Each fiber should be as close as possible before they are

connected.

Sensing distance will be reduced by approximately 25% when

fibers are connected.

Only fibers with 2.2 mm dia. can be connected.
