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

A: No, you can’t, STM-64 not support SFP module change.


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 SSN4SLD64(S-64.2B,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 SSN4SLD6402 board?

  1. Ernesto

    Due to location in China, shipping is somewhat longer than may be expected.

  2. Trung

    My client is very satisfied with this order. Now he want to purchase one more STM64 card with 80km sfp, or even you can support more than 80KM, please list them also. Thanks!

  3. June

    I never met a sales manager like Cherry, she is always patient to my questions, and response my question on time.

  4. Coco

    It’s very nice about this board, fast delivery and high quality
