Chapter 4 Turn Up and Test
ERp—Expected receiver power
MTp—Measured transmitted power at the LM OUT port with attenuators attached
HFM—Number of filters the signal passes through, starting at the LM IN port, before it reaches the
CLIP module
2.5—Value (in dB) that must be subtracted to account for the combined loss in the pass-through of
the NAM and the drop in the HFM and the LM.
Note Do not remove the fibers.
Step 7 Set the data rate for each CLIP module if the desired rate differs from the default value (the default is
OC-48/STM-16):
a.
At the NCB:> prompt, type
configure clip clip_xxx
where xxx is the serial number of the CLIP
module. Press Enter. (The CLIP module serial number can be found on the CLIP module, or by
typing the
show inventory
command.)
b. Type
list value
and press Enter. Verify the data rate.
c.
To change the data rate, type
datarate <rate>,
where <rate> is STM-1, OC-3, STM-4, OC-12,
STM-16, OC-48, or gbit_eth. Press Enter.
d. Type
list value
and press Enter to verify that the change was accepted.
e.
Type
exit
to quit the CLIP module.
f. Repeat Steps a – e for all CLIP modules.
Step 8 Check the client side transmit levels:
a. Connect a fiber from the transmit port of the signal generator to the client IN port for the first CLIP
(slot one). The valid input range on the client side receive is -3 to -18 dBm.
b.
Run a jumper cable from the client OUT port of the first CLIP to your power meter.
c. Set the wavelength on the power meter to 1310 nm.
d.
Measure and record the output power of the client side transmit in Table B-9 on page B-5 .
e. Repeat Steps a – d for all remaining CLIPs (connect the test set to the IN port of the current CLIP and
the power meter to the OUT port of the same CLIP).
Procedure: Check Alarms
Continue with the following steps to verify that no alarms exist.
Step 9
Connect all CLIP modules in a daisy chain:
a. Connect a fiber from the transmit port of the signal generator to the client IN port on the first CLIP
(Slot 1). The valid input range on the client side receiver is -3 to -18 dBm.
b.
Run a jumper cable from the Client OUT port of the first CLIP module to the client IN port of the
second CLIP module (Slot 2).
c. Repeat until all CLIP modules are daisy-chained together with the last CLIP module’s OUT port
returning to the test set, as shown in
Figure 4-4 .
