Q & A

Q: What the difference between different functional version? 

A: SLQ1 is available in three functional versions, namely, N1, N2, and N4, N4 version also called ND0 version. The N2SLQ16 is discontinued. The difference as below:

Color Interface(CWDM, DWDM)Not supportedNot supportedSupported
single-fiber bidirectional optical modulesNot supportedNot supportedSupported
AU-3 serviceNot supportedSupportedNot supported
inloops/outloops on VC-4 pathsSupportedNot supportedSupported
TCM functionNot supportedSupportedNot supported
Detection and query of the voltageNot supportedNot supportedSupported

Q: What the board substitution relation among different versions?

A: When the AU-3 services and TCM function are not required, the N1SLQ16 and N2SLQ16 can be substituted with each other. The N4SLQ16 supports the board version replacement function to substitute for the N1SLQ16/N2SLQ16.
