1. Connect Jumpers
WARNING: Never look directly into the end of a ber that may be
carrying laser light. Laser light can be invisible and can damage your
eyes. Viewing it directly does not cause pain. The iris of the eye will
not close involuntarily as when viewing a bright light. Consequently,
serious damage to the retina of the eye is possible. Should accidental
eye exposure to laser light be suspected, arrange for an eye
examination immediately.
• Make the connections in the rst cassette as described in this section.
• Then route the jumpers as described in Section 2 or 5for your application.
• Lastly, make the connections in the second cassette following the
instructions in this section.
Step 1: If routing jumpers to an adjacent frame, start with the most densely
loaded frame (source frame). Pull module out to detent position
(Figure 1).
Figure 1
Step 2: Press buttons on each side of the cassette (Figure 2) and lower the
handle.

Step 3: Remove dust caps and clean adapters and connectors per
standard company practices or as described in Section 6. Connect
jumpers as required (Figure 3).
Figure 3
Step 4: Dress jumpers under the aps on the handle and out the left side of
the cassette (Figure 3).
Step 5: Then raise the handle until the buttons on each side engage to hold
the handle up (Figure 4).
Step 6: Lastly, close the cover over the jumper cables.

2. Jumper Routing and Slack Storage when Cross-
connecting in the Same Frame
When cross-connecting jumpers within one frame, use a single-ber
jumper length of 4 m (13 ft) to eliminate the need to cut jumpers to a
specic length.
• Determine location of jumper termination.
• Connect both ends of the jumpers to the selected adapters, then route
slack under both transition spools and over the highest hub that can
be reached without pulling on the jumper.
• If the termination is within the same frame, refer to Figure 5. If the
jumper termination is within another frame, skip to Section 5.

3. Cross-connecting Jumpers in Adjacent Frames
3.1. Cross-connecting Jumpers in Adjacent Rear Cable
Access Frames
When cross-connecting jumpers to adjacent rear cable access frames,
use a length of 6 m (16.25 ft), plus 1.0 m (3.3 ft) for every additional
frame passed.
• Always use rear troughs to transition between frames.
• Distribute ber between different troughs and hubs in the interbay unit
(IBU) to minimize ber loading.

3.2. Cross-connecting Jumpers in Adjacent Front Cable
Access Frames
When cross-connecting jumpers to adjacent front cable access frames,
use a length of 6 m (16.25 ft), plus 1.0 m (3.3 ft) for every additional
frame passed.
• Always use lower troughs to transition between frames.
• Distribute ber between different hubs in the inter-bay unit (IBU) to
minimize ber loading.

4. Cross-connecting Jumpers Using Overhead Trough
System
Use overhead trough systems to route jumpers as shown in Figure 11 when:
• frames are not adjacent to each other in the same frame lineup or
• frames are not in the same frame lineup.
Figure 11
TPA-4455

STANDARD RECOMMENDED PROCEDURE 003-960 | ISSUE 4 | OCTOBER 2017 | PAGE 12 OF 18
5. Jumper Routing and Slack Storage when
Interconnecting between Frames
• Rear cable access frame: Always use rear troughs to transition
between frames.
• Front cable access frame: Always use bottom troughs or overhead
trough system to transition between frames.
• Distribute ber between different troughs and hubs in the IBU to
minimize ber loading.

5.5. Interconnecting Jumpers between Distantly Spaced
Ports
• When connecting ports 1 through 12 of a 24-port cassette or ports 1
through 18 of a 36-port cassette to another cassette’s ports 1 through
12 or 1 through 18, it is recommended to add one additional inner hub
to the routing path.
• It is recommended to use the same routing scheme when connecting
housing 5’s ports to housings 6 through 10 using the inner hubs to
address the dimensional differences.

6. Connector Care and Cleaning
WARNING: Isopropyl alcohol is ammable with a ashpoint at 54ºF.
It can cause irritation to eyes on contact. In case of contact, ush
eyes with water for at least 15 minutes. Inhalation of vapors irritates
the respiratory tract. Exposure to high concentrations has a narcotic
effect, producing symptoms of dizziness, drowsiness, headache,
staggering, unconsciousness and possibly death.
• Always keep dust caps on connectors and adapters when not in use.
• Ensure dust caps are clean before reuse.
• Use optical cleaning materials as standardized by your company.
• Clean the connector before every mating, especially for test equipment patch
cords (jumpers.)
• A minimum level of cleaning is listed below. Local procedures may require
more rigorous cleaning methods.
Step 1: Remove plugs from the connector adapter.
Step 2: Wipe the connector ferrule twice with a lint-free wiping material
moistened with isopropyl alcohol. Then wipe across the end of the
ferrule.
Step 3: Repeat previous step with a dry wipe.
