Connecting POTS

If POTS cables are not available, refer to 

Figure 2 

and the following 

procedure to create the POTS cables:

1. Trim the insulation for the subscriber POTS cables.
2. Refer to the illustration below and connect the twisted pair Tip 

(green) and Ring (Red) to the RJ-11 connector using an RJ-11 
crimper.

3. Insert the RJ-11 connector in the appropriate POTS 1 or POTS 2 

jack.

Connecting Ethernet 

The SFU ONT supports four 1 Gigabit (10/100/1000Base-T) connec-
tions (

LAN 1

 to 

LAN 4

). 

If Ethernet cables are not available, use the following procedure and 
table to create the Ethernet cables:

1. Trim the insulation for the subscriber Ethernet cable.
2. Connect the wires per the following table using an RJ-45 

Crimper.

3. Insert the CAT 6 rated cable in the appropriate 

LAN 1

 through 

LAN 4

 ports.

CAUTION

!

LASER RADIATION
1500 nm to 1600 nm
Do not view directly with optical instruments.
This product contains a Class 1M Laser module that complies with 21
CFR 1040.10 and 1040.11 and IEC 60825-1 and -2.

Fiber is installed in an SC connecter located behind a removable 
protector panel on the right-rear of the SFU ONT. Refer to 

Figure 3

 

when installing fiber:

1. Remove the phillips-head screw from the right side of the fiber 

protector panel.

2. Slide the protector cover back to expose the SC connector.

Installation consists of positioning the SFU ONT either on a desktop 
or wall mount, connecting POTS, Ethernet and Fiber, and connecting 
power.

Required tools

Standard technician tools and those listed below are required for 
installing the SFU ONT:

Carpenter’s level

3/32 inch screw driver for connecting SFU ONT power

RJ-45/RJ-11 crimper

A telephony/data communication test set

PON power meter with wavelength filtering

Fiberscope or videoscope

Two #8 Pan Head screws (1 inch or greater in length)

Assorted tie wraps for securing cabling and wiring

For fiber optic connections, the following are required:

Fiber Optical Fusion Splice Tools

ODC Fiber cleaning tool

SC Fiber connector

Desk Top Installation

The SFU ONT can sit on a desktop or be wall mounted. With a desk 
mount, ensure the SFU ONT is not located in direct sunlight and is 
not located next to any thermal obstructions. 

Wall Mount Installation

The SFU ONT can be wall mounted.
To wall mount the SFU ONT, reference 

Figure 1

 and complete the 

following steps:

1. Decide on a location for the SFU ONT. Mount below eye-level 

so the LEDs are visible.

Figure 1. Wall Mount SFU ONT

2. Attach a 1/4 inch mounting board (typically plywood) to the 

wall. If the wall is drywall construction, ensure the mounting 
board is supported by the wall studs.

3. Install two #8 Pan Head screws (1 inch or greater in length) 

using the key holes on the back of the SFU ONT as location 
markers. Leave approximately 1/4 inch protruding from the 
mounting surface.

4. Slide the SFU ONT over the Pan Head screws and exert a small 

amount of downward pressure to ensure that the top of the 
slots are resting on the shafts of the Pan Head screws.
