Q: Can I get 40km 10GE optical SFP+ modules?
A: Yes, but it not popular deployed in a OLT system, you may contact our sales to get more details.
Q: Can I have GE uplink interface board and 10GE uplink interface board in the same OLT?
A: Yes, you can, 1PCS X2CS board (2 10GE uplink ports) and 1PCS GICF board (2 GE uplink ports) in one OLT chassis.
Q: Can I use OLT main control board SCUN as uplink so as to save the uplink board cost?
A: Yes, you can, but we don’t suggest, as Huawei OLT SCUN load balance is not well supported, so most customers are using SCUN in active/standby mode, if OLT lose power, which SCUN will work as the active SCUN will be randomly, which may affect service, also if the link is down, the active SCUN will not shift to the standby SCUN (it will only shift when SCUN board is down), then service may get affected also.
Q: Can I get technical support from thunder-link.com if we purchase X2CS from you?
A: We will able to provide technical support service for customers whose OLT and optical interface card are both from us, kindly note we will charge for the technical support service. We suggest customers purchase the OLT and X2CS card from the same professional supplier so as to avoid compatible and technical issues.
