Q: What the difference between different functional version? 

A: SLO1 is available in two functional versions, namely, N2 and N3, The N3SLO1 is discontinued. The difference as below:

AU-3 serviceSupportedNot supported
inloops and outloops on VC-4 pathsNot supportedSupported
TCM functionSupportedNot supported
PRBS functionNot supportedSupported

Q: What the board substitution relation among different versions?

A: When the N2SLO1 is not configured with the TCM function and AU-3 services, the N3SLO1 can substitute for the N2SLO1.

Q: What is the difference between different function code?


BoardFeature CodeOptical InterfaceTransmission Distance

Q: Can I change SFP module to reach longer transmission distance?

A: Yes, you can, please contact sales team, for available SFP module and cost.

Q: Can I equip different specification SFP module on different port, to perform different transmission distance for each port?

A: Yes, you can, but that not recommended.

Q: Can I use compatible SFP module on SSN2SLO1(S-1.1,LC) board?

A: Yes, you can, the board might generate alarm, but it won’t affect use.

Q: Can I return/exchange board if not compatible with my system?

A: Yes, please tell our sales team your system and main control board version, before your purchase.

Q: The board is new or refurbished? 

A: Yes, it is original new, not been used.

Q: Do you sell SFP module separately? 

A: Yes, we do.

Q: What is the lead time for SSN2SLO1(S-1.1,LC) board? 

A: In normal condition is 5days, better to confirm with our sales team before your purchase.
