 FAQ

• How can you guarantee the quality of the transceiver?

​

All-optical transceivers are produced in the dust-free workshop through strict quality control on

raw material and assembly, and comprehensive testing on the optical spectrum, eye pattern,

bit error rate and ageing in low or high temperature for reliability

• Do your SFP have a quantity warranty?

​

​Yes, all transceivers provide three years quality warranty. For any hardware defects,

our after-sale team will take the issues seriously and figure out the solution for the clients

to return, replace, repair and refund the broken items.

Topstar has marketed SFP transceiver since 2006 and served its clients for over 15 years,
