TERMINATION

In a typical application, the LSX panel serves as a splicing and distribution point to transition from Outside Plant (OSP) or Intra Facility Cable (IFC) to inbuilding circuits connected to with patch cords. The panel may be used in either an interconnect or cross-connect configuration, and in either singlemode or multimode applications.

Figure 1 summarizes the functional components of the LSX termination panel. As shown, an

OSP or IFC cable is routed through the panel to the splice area access door, which serves as a splice deck. On the splice area rear access door, located on the rear of the panel, the component fibers are spliced to the internal pigtails. The factory-terminated internal pigtails transition to the bulkhead, located on the front of the panel. Patch cords installed from the front side of the panel provide the connection to fiber optic terminal equipment.

5.4 Installing a Cable Clamp

Every LSX panel is shipped with a cable clamp that can be used to secure a cable to the chassis. This section contains instructions for the 7-inch and 9-inch high panels. For other panel heights, refer to the instructions provided in the cable clamp kit.

To install the cable clamp, use the following procedure. Refer to Figure 10 for the 7-inch panel and Figure 11 for the 9-inch panel.

Note: The figures show the cable clamp bracket positioned for cable routing from above the panel. For cable routing from below the panel, turn the cable clamp bracket upside down compared to how it is shown in the figure and use the mounting holes designated in the figure as “for under floor cable entry.”

1. Install the cable clamp bracket on the clamp mount plate using two #12-24 screws. Be sure to position the cable clamp bracket corresponding to the note above.

2. Place the two standoffs in the standoff mounting holes in the cable clamp bracket.

Note: There are four standoff mounting holes. Either the two left holes or two right holes

Page 12

can be used together, not the two in the middle. Do not mount two cables side by side.

GUIDE

Cross-connect patch cords on the LSX panels and LGX frame must be carefully routed to ensure they are properly protected. For details, refer to the following subsections.

Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical adapters of the adapter packs. Exposure to invisible laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating adapter or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the adapter or connector.

6.1 Patch Cord Routing Within the LSX Module

Route patch cords vertically down the front of the adapter pack on each panel then left or right through the guides and radius limiters on the LSX panel (see

ADCP-93-095 • Rev B • April 2018

Figure 17).

6.2 Routing Patch Cords on the LGX Bay

When routing patch cords on the LGX bay, allow for a minimum of 6 in. (152 mm) of slack loop in the vertical trough. This loop aids in the tracing of patch cords and also facilitates removing a patch cord from the bundle. Additional fiber slack should be expected when installing a set of pre-connectorized patch cords. Refer to the following topics for patch cord details for a standalone bay, adjacent bays, and non-adjacent bays.

6.2.1 Cross-Connecting Within a Stand-Alone Bay

Cross-connecting within a stand-alone bay (shown in Figure 18) may be required when facility and equipment terminations are intermixed.

Most cross-connection routing within a stand-alone bay should be done with 5 meter (16.5 ft.) patch cords. Shorter 3 meter (9.9 ft.) patch cords can be used when both ends are terminated in the top half of the bay.

Use the following procedure to route patch cords on a stand-alone bay.

1. Loop the patch cord across the upper raceway.

2. Route the right side of the patch cord down through the right vertical trough to the LSX panel where the right side of the patch cord will be terminated.

3. Route the left side of the patch cord down through the left vertical trough to the LSX panel where the left side of the patch cord will be terminated.

4. Route the ends of the patch cords inward from the vertical troughs to the respective points of termination. Connect the two ends of the patch cord at the desired adapters.

Note: On same side terminations, one end of the patch cord will extend across the midline of the bay, as shown in

Figure 18 for patch cords 2 and 3. On opposite side terminations,

the patch cord will not extend across the midline of the bay.

5. Adjust the slack length at both ends of the patch cord to about equal length and dress the excess length within the jumper retainers.

6.2.2 Cross-Connecting Between Adjacent Bays

Most cross-connection routing between adjacent racks should be done with 6 meter (19.8 ft.) patch cords. Shorter 4 meter (13.2 ft.) patch cords can be used when both ends are terminated in the top left of the frame. To route patch cords between adjacent bays (shown in the following procedure.

Figure 19), use

1. Terminate one end of the patch cord on the originating LSX panel and bay, then route the

Page 22

Figure 19. Routing Patch Cords Between Adjacent Bays

patch cord left or right to the nearest vertical trough.

ADCP-93-095 • Rev B • April 2018

2. At the destination panel and bay, terminate the opposite end of the patch cord, then route the patch cord left or right to the nearest vertical trough.

3. Loop the patch cord over the upper raceway or jumper support bracket to the adjacent rack.

4. Adjust the slack length at both ends of the patch cord to about equal length and dress the excess length within the jumper retainers.

6.2.3 Cross-Connecting to Non-Adjacent Bays

Patch cords may be routed through upper or lower raceways to non-adjacent bays in an LGX or LSX lineup. As a general rule, patch cords originating in LSX panels located in the upper half of an originating bay are routed to the upper raceway. Conversely, patch cords originating in panels located in the lower half of an originating bay are routed to the lower raceway.

6.2.3.1 Patch Cord Length Selection

Patch cord length is a concern when cross-connecting to non-adjacent bays because the bays may be at various distances from one another. To select the correct patch cord length, you must take into account the number of bays to be traversed and which raceways will be used to route the patch cord. To select a patch cord based on these factors, refer to

4. Route the end of the patch cord terminated in step 3 up the left or right vertical trough and over the upper raceway across the top of one bay as shown in

Figure 20 and Figure 21.

Note: Use the lower trough as the main raceway since it tends to be less congested. Route the patch cord through the upper raceway for one bay length only.

5. Insert the patch cords in the lower raceway between the origin and destination bays. Adjust the slack loops in the vertical troughs to prevent buildup within the raceway.

Frames with a depth of 15 inches (38.1 cm) are recommended to accommodate the 15 inch depth of the LSX termination/splice panel. The additional depth of the termination/splice panel is due to the due to the additional room required for the splice deck on the rear of the panel. Termination only panels have a depth of 12 inches.

If a 15 inch deep frame is not available, use a rear duct extension kit to extend backward the rear doors of the frame. The new 15 inch deep frame will line up with any existing 12 inch deep (30.5 cm) frame as shown in
