EDFA-S20H and EDFA-S20L Modules
EDFA-S20H and EDFA-S20L Modules
This subsection will help you resolve issues that might be experienced on extended variable gain EDFAs, namely the high gain EDFA-S20H and the low gain EDFA-S20L
modules. It is assumed that the measurements for all interfaces are within ADVA Optical Networking specifications. If not, refer to “Finding Your Problem - Follow the
Light” on p.53 in this document.
CAUTION
Follow all the instructions precisely. If you do not supply the specified attenuation on given steps, you will destroy the module being tested.
Note
If your module has an LED status that is not represented in Table 91 on p.487, please contact your ADVA Optical Networking Technical Services
Representative.
Each EDFA-S20H/EDFA-S20L module has four LEDs on its faceplate:
• “P” to indicate the power supply status
• “Mod” to indicate the operating status of the module
• “N” to indicate the operating status of the network port
• “U” to indicate the operating status of the upgrade port
Note
The module should lose power for at least 10 seconds to allow any and all capacitance to dissipate.
