4.

If utility or service wiring is to be routed through the wall, drill out the appropriate access

holes in the fiber management tray, taking care not to damage the unit.

Note:

The round pass-through holes in the assembly are 3/4" in diameter.

Note:

The fiber management tray can be attached directly to a standard electrical outlet using

the provided mounting holes as shown below.

Wall Mounting the Fiber Management Tray

The GigaCenter can be mounted to a Fiber Management Tray or a Structured Wiring

Enclosure.

Note:

Calix recommends using the wall mount method whenever possible to ensure ongoing

integrity of the fiber connection and outgoing subscriber services.

To wall mount the GigaCenter

DANGER!

High voltage electrical and pressurized natural gas lines may be

present. Make sure you fully understand the locations of these and all other utility

connections before drilling through any surface.

1.

Determine the location of the GigaCenter on any suitable vertical surface.

Note:

Make sure you allow for adequate bend radius on the connector side of the unit.

Note:

Make sure to allow adequate space for service cable routing.

2.

Mark the mounting screw hole locations using the diagram below for reference.

3.

Using a proper sized drill bit for the mounting screws required, pre-drill the mounting

hole locations.

Mounting hole locations for the GigaCenter and the Integrated Fiber Management Tray are

shown below for reference:

Installing the Composite Cable - Wall Mount

With the Integrated Fiber Management Tray mounted to the wall, the incoming composite

fiber must be installed and spliced into the Integrated Fiber Management Tray.

ALERT!

A protective cap or hood must be placed over any radiating

bulkhead receptacle or optical fiber patch cord.

CAUTION!

Use of controls or adjustments or performance of procedures

other than those specified here may result in hazardous radiation exposure.

DANGER!

A Class 1 laser product with an internal Class IIIb hazard is used in

this equipment. Use an optical power meter to identify active fibers. Never

assume laser power is turned off or that the fiber is disconnected at the other

end.

Overview of procedure

Note:

For the purposes of these instructions, it is assumed that a Local Convergence Point

(LCP)has been located somewhere near the planned GigaCenter installation site and that a

5mm fiber pigtail will be used to connect the GigaCenter to the GPON network.



Prepare the pigtail for splicing onto the end of the incoming composite cable.



Prepare the composite cable for splicing.



Fusion splice the pigtail and composite cable together.



Route and secure the spliced components into the Integrated Fiber Management Tray.

To install the composite cable

1.

Route the 5mm fiber pigtail from the LCP

2.

Locate the incoming fiber composite cable and route it through the fiber access slot as

shown below.

3.

Wrap any excess fiber around the fiber management stays inside the assembly. Make sure

the amount of slack available closely matches the example below (the pigtail must be

connected to the GigaCenter without exceeding bend radius specifications).

4.

Use cable ties as necessary to fully secure the excess fiber, being careful not to over-

tighten the cable ties and thereby crimping the fiber.

Installing the GigaCenter onto the Fiber Management Tray

With the 5mm fiber pigtail threaded and secured to the mounted fiber management tray, the

GigaCenter can now be secured to the fiber management tray The proper mating of these

two pieces is critical in ensuring the fiber pigtail is not pinched or kinked during the assembly

process.

During the assembly process, the GigaCenter will slide onto the rails of the fiber

management tray and as the GigaCenter slides down (or across), the 5mm fiber pigtail needs

to be routed around the GigaCenter and connected to the bulkhead fitting.

To assemble the GigaCenter onto the fiber management tray

Note:

Refer to the images below for guidance in assembly the GigaCenter to the fiber

management tray.

1.

Press and slide the fiber access cover down to remove it from the front of the

GigaCenter. Set aside temporarily.

2.

Center the GigaCenter over the fiber management tray and tip the GigaCenter slightly to

one side or the other in order to clear one of the retainer tabs on the fiber management

tray.

3.

Once clear, guide the GigaCenter onto the embossed glide of the fiber management tray.

The glide should be positioned between the 2nd and 3rd channel of the GigaCenter unit.

4.

Rotate the trailing edge of the GigaCenter down while manually bending the remaining

retaining tab out of the way.

5.

With the GigaCenter partially engaged into the fiber management tray, grab the pigtail

end and connect it to the bulkhead fitting on the GigaCenter (Figure 2).

6.

Once clicked into place, wrap the 5mm fiber around and behind the GigaCenter making

sure it does not kink or get pinched between the tray and GigaCenter.

7.

Continue sliding the GigaCenter down (or across) until it is full seated on the fiber

management tray (Figure 3).

8.

Ensure the GigaCenter has cleared the retaining tabs on each end and that the retaining

tabs are "locking" the GigaCenter in place.

9.

Double-check the fiber pigtail is secured and is not pinched or kinked in any way.

10.

Re-attach the fiber access cover.

11.

Locate the screw for attaching the fiber access cover (shipped in a small bag) to the

GigaCenter and tighten.
