Step 2
Open Maintenance Manager and expand the ONS 15201 SCU information.
Step 3 Record the information for the Client Layer Interface Port (CLIP) module in Table B-12 on page B-7 .
Locate the CLIP information in the following places:
•
Table 4-2 provides ITU channel, wavelength, and frequency information for the ONS 15200 system
CLIP module.
• The CLIP module label provides the serial number, channel number, transmit power level, and
information about protection status. “VL” indicates very long range (0 dBm; 3000 ps/nm dispersion
tolerance), “L” indicates long range (+7 dBm laser with 1800 ps/nm of dispersion tolerance), and
“M” indicates medium range (0 dBm with 1800 ps/nm of dispersion tolerance).
•
“U” means unprotected and “P” means protected.
• The frequency is based on 19x.x THz, where x.x is the associated channel number.
•
The splitter ratio appears on the SCU above the DWDM ports.
• If you are planning to use an MU attenuator, insert the attenuator in the middle port on the CLIP
interface (labeled with an arrow pointing away from the CLIP).
Step 4
Compare data in Table B-12 on page B-7 with data provided by the network planner, and verify that the
data is consistent. Complete Step 4 in Table B-11 on page B-7 .
Step 5 Check the output power. Unprotected channels will have an output on only one of the DWDM ports.
a.
Connect an optical-fiber jumper cable from the A-side output port to a wavelength meter or an
optical spectrum analyzer (OSA).
b. Set the wavelength range on the OSA to a value between 1530 and 1560 nm. Record the wavelength
and the output power in
Table B-13 on page B-7 .
c.
Repeat Steps a – b for the B side and record the information in Table B-13 on page B-7 .
Note
The network planner provides the expected output power.
