FAQ-Can the 622 Mbits Optical Interface on an OptiX NG-SDH NE Be Amplified by Using the BA2

Publication Date:  2012-07-25 Views:  41 Downloads:  0
Issue Description
Q:
Can the 622 Mbit/s optical interface on an OptiX NG-SDH NE be amplified by using the BA2? 
Alarm Information
Null
Handling Process
A:
The 622 Mbit/s optical interface on an OptiX NG-SDH NE cannot be amplified by using the BA2. On the current OptiX NG-SDH NEs, all the 622 Mbit/s optical boards work with small form-factor pluggable (SFP) optical modules. The modules operate at a wavelength range of 1500 nm to 1580 nm. The BA2, however, can amplify a wavelength range of 1520 nm to 1560 nm. Therefore, the 622 Mbit/s optical interfaces cannot be amplified by using the BA2.
All the SFP optical interfaces on the OptiX NG-SDH NEs cannot be amplified by using the BA2, no matter what rate they operate at. Currently, the optical boards at the only 2.5 Gbit/s rate or lower rate support SFP optical modules.
