Optical Amplification Operation Verification Procedure - Cisco 15216 EDFA2 Operation Manual

SC/UPC Optical Ports
Connect the second patchcord to TERMINAL OUTPUT. Measure and record the total optical power:
Step 3
a.
b.
If optical power at the end of the TERMINAL OUTPUT patchcord is less than or equal to +4 dBm,
Step 4
connect the end to the ONS 15216 EDFA2 input. If the optical power is greater than + 4 dBm, additional
optical attenuation is required to bring optical power below + 4 dBm.

3.4.3 Optical Amplification Operation Verification Procedure

To verify ONS 15216 EDFA2 optical amplification, use the following procedure:
Connect an optical power meter to the MONITOR OUT port.
Step 1
Step 2 Measure and record the output power. The MONITOR OUT port level is –20 dB less than the signal.
Step 3 Verify that the ONS 15216 EDFA2 input and output power are within the range shown in
For example, if the total input power is between –27 dBm and –5 dBm, expect an output power between
–5 dBm and 17 dBm.

Gain
(dB)
22
Note Unless overridden by the user, the gain per channel is by default set to 22 dB by the ONS 15216 EDFA2.
Gain is fixed at 22 dB as long as total input power is less than or equal to –5 dBm. If your input power
is higher than –5 dBm, see the
