Q: What the difference between different functional version?

A: SLQ16 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:

N1 N2 N4/ND0
Color Interface(CWDM, DWDM) Not supported Not supported Supported
single-fiber bidirectional optical modules Not supported Not supported Supported
AU-3 service Not supported Supported Not supported
inloops and outloops on VC-4 paths Supported Not supported Supported
TCM function Not supported Supported Not supported
