Thanks for your question. Both two solutions you menbtioned can meet the transmission need. When the distance and loss of the two paths are the same, we recommend the first way. Please notice that if there's no DCM and EDFA, it will affect signal transmission of the both paths, but amplifying AFTER the OLP is safer. You can choose according to your application environment. от FS.COM 10/09/2018

Hello, please try the following Snmpwalk commands to monitor the FMT chassis card;
1. "snmpwalk -Cc -c public -v1 10.172.1.222 enterprises.40989.10.16", this command is an example of reading the IP address 10.172.1.222 chassis command, here it need your actual IP address shall prevail.
2. If you want to read the chassis of other IP addresses, you also need to modify the IP address, "snmpwalk -Cc -c public -v1 IP(xxx.xxx.xxx.xxx) enterprises.40989.10.16".
3. Please help to confirm if you have entered the correct IP address and command. от FS.COM 06/08/2018

In the normal condition of the main path and the backup optical fiber, OLP card cannot be switched automatically. Only when one of the lines is cut off and the protection line is normal, automatically switch will be achieved. от FS.COM 05/17/2018

O/E/S/C/L band signals can be passed through. But since there is power monitoring and switching threshold judgment in OLP, and the wavelength in OLP is the judgment range for monitoring data. If you doesn't choose the corresponding wavelength, it will cause error in power monitoring and switching threshold judgment. от FS.COM 05/15/2018

Thanks for your question here. The power parameter is less than 5W of this equipment in 48V DC. от FS.COM 01/04/2018

Fiber type (SMF 1310±50nm/1550±50nm, MMF 850±50nm), protected mode ( 1:1, 1+1) and power type (100-240VAC , 36-72VDC) should be confirmed. от FS.COM 07/20/2017

Yes, both OLP and OBP card can be used with FMT managed chassis. от FS.COM 06/27/2017

Optical protection system can monitor the optical power status of network transmission line and network node. In case the current optical power of optical fiber is less than pre-set switching threshold value, then alarm is on and it would switch to standby optical fiber automatically to protect optical transmission system line. от FS.COM 06/05/2017
