Cisco ONS 15216 EDFA2/EDFA2-A Operations Guide, R2.4
July 2004
Chapter 3 Installation
3.3.2 Optical Connection Procedure
3.3.2 Optical Connection Procedure
Warning
Follow all directions and warning labels when working with optical fibers. To prevent eye damage,
never look directly into a fiber or connector.
Connect the customer-supplied fiber optic patchcords to the SC/UPC optical ports of the ONS 15216
EDFA2 using the following procedure. Refer to Figure 3-1 while performing this procedure:
Step 1 Clean both ends of the two fiber optic patchcords. Refer to the Cisco document “Cleaning Procedure for
Fiber Optic Connectors” for more information.
Step 2 Connect the first patchcord between the ONS 15216 EDFA2 OUTPUT connector and the FACILITY
LINE connection.
The measured optical output power should be approximately –3.5 dBm.
Step 3 Connect the second patchcord to TERMINAL OUTPUT. Measure and record the total optical power:
a. DWDM/OADM output
b. Terminal transmitter output
Step 4 If optical power at the end of the TERMINAL OUTPUT patchcord is less than or equal to +4 dBm,
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.

3.3.3 Optical Amplification Operation Verification Procedure
To verify ONS 15216 EDFA2 optical amplification, use the following procedure:
Step 1 Connect an optical power meter to the MONITOR OUT port.
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 Table 3-1.
