Q&A

-------------------------------------------------------------------------------------------------------------

Q: What is the SFP Transceiver?

 

A: SFP Transceiver is hot pluggable, this make it easy to change and easy for maintenance compared with traditional modules.

 

SFP fiber transceiver modules make the fiber optic network or fiber-Ethernet network easier to upgrade or maintain, users can replace a single SFP module during the process instead of replace the whole board with many modules on it.

 

 

Q: How about the SOPTO's SFP products?

 

A: SOPTO is an original manufacturer of SFP transceiver, we have sufficient transceiver modules in stock, and ready to ship upon your request. We have years experiences in offering SFP transceiver, we can provide 3 years warranty as well as life time technical supports for SFP transceiver.

 

Every transceiver module will be tested before shipping, we guarantee all of our SFP transceiver can be 100% compatible with your networking devices.
