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.

    This board equipped with S-16.1 SFP, can I use L-16.1 SFP module on this board also?
  2. Global
    Easy to find everything, whether you know you need it or not.
  3. Global
    This board is very nice, and their service is better than other distributors, I will come back next time. like it very much.
  4. Global
    I hope the next logistics can be faster.
  5. Global
    Very satisfied with their service and high quality products, the only disappointed is slowly delivery.
  6. Global
    Great service, would use again without hesitation.
  7. Global
    This is the first time to buy products from Thunder-link, the sale manager is very patient for me, and they presented me some fibers,
    but there still have a error, there is a small scratches on the board, but the sale manager tell me, this scratches appear when test the board before sending to me, In general, the shop is trustworthy
