Q: Do you support customization?
A: Definitely yes; customization is available according to your product requirements.
Q: Can I get a sample first?
A: We do offer samples before making any production so that the production is up to the buyer's expectations. Samples can be delivered within 5-8 days.
Q: What is your MOQ?
A: 1 piece is available. We can also provide free samples for our valued customers.
Q: What's the max real distance I can cover with this module?
A: Hello, the theoretical environment is 40 km. The actual environment needs to be calculated based on the actual link loss.
Q: Hello, I need to use 40 km 40G ER4 for a transmission distance of 20 km. Do I need to add an attenuator?
A: Hello, the actual link is 20 km without adding attenuation.
