Fiber Optic Trunk Interface
Page 1 of 3
Product Description
The Fiber Optic Trunk Interface (refer to Figure 1)
converts the building level network (BLN) and floor
level network (FLN) trunk electrical signals (RS-485)
into light energy for transmission over a fiber optic
cable and converts the light energy from a fiber
cable back to RS-485 signals. The device is
designed to work with either the BLN or FLN trunk at
speeds of 300 bps to 230K bps, with a link budget of
11.5 dB.
There are no internal settings or user-serviceable
parts in the Fiber Optic Trunk Interface. The
interface requires a duplex fiber cable between
interfaces (one fiber for transmit and one for
receive). ST style port connectors are included.
The Fiber Optic Trunk Interface is housed in a 1.5” ×
4” × 4” metal enclosure. It contains one power input
receptacle, one three-position trunk port, one fiber
transmit port, and one fiber receive port (refer to
Figure 2). The interface is powered by a 6 Vdc
external power pack (included). All circuits are
supervised and power limited.

• Wire cutters or wire strippers
• 7/16-inch (11.1mm) nutdriver
Expected Installation Time
15 minutes
Prerequisites
CAUTION:
Avoid mounting the interface in a position
that forces the fiber to make turns tighter
than a three-inch radius. The mounting
surface must also be vibration free.
• Fiber cable installed and terminated with
proper connector.

Installation Instructions

• Individual fibers identified as Transmit and
Receive.
• A report from the fiber installer showing the
loss of optic power per section of fiber cable,
including all connectors. The loss must be
less than the required link budget.
• Source of transient protected for 115 Vac or
230 Vac. All field panel outlets are protected
or an MOV protected 120 Vac duplex outlet
(P/N 529-804), or three 250 V operation
(refer to Figure 7) can be ordered.
• The BLN or FLN trunk has been checked for
opens, shorts, and proper shielding.
• The mounting bracket (if used), or other
locally fabricated bracket, is available.
Instructions
1. If wall or rack mounting brackets are being
used, refer to the installation instructions for the
brackets (P/N 538-718).
2. Remove the protective cap from the transmit
port and transmit fiber, and connect the fiber to
the port labeled “TX” (refer to Figure 2). Do not
use any tools to tighten the connectors.
3. Remove the protective cap from the receive
port and receive fiber, and connect the fiber to
the port labeled “RX” (refer to Figure 2). Do not
use any tools to tighten the connectors.
4. Connect the BLN or FLN trunk to the trunk
connector. Then plug the connector into the
port labeled “Trunk” on the interface.
5. Connect the earth ground wire (2’ green wire,
included) from the trunk shield connection to
earth ground. The ground can be either the field
panel chassis using the nutdriver to put the
ground terminal under the chassis mounting nut
or the electrical box which powers the interface.
6. Connect the power connector into the interface
and plug the power pack into a transient
protected source.
The installation is now complete.
