Note that Mikrotik RouterOS before 7.15beta4 requires the fiber to be plugged before allowing ping/telnet/webGUI to the xPON SFP.
This will trigger an alarm on the OLT at least on the first config.
It is suggested upgrade to 7.15 and activate "Interface/SFP/Ignore Rx LOS", or use a media converter for the first config.

## Bridge Mode

Bridge mode allows full HSGMII speed without any major issues and seems to work in mixed mode too.

Positive results in mixed mode with the following hardware:

|                                                                         | Huawei MA5671A |
| ----------------------------------------------------------------------- | -------------- |
| [6COM 6C-SFP-10G-T-Intel](https://www.amazon.it/gp/product/B07H9Q91WV/) | ✅             |

In any case, the use of a DAC or MikroTik S+RJ10 is always recommended.


## Router Mode

Unfortunately the CPU will have a major impact on end performance with resulting downlink speed topping at ~700Mbps.

Note that when using **Huawei MA5671A with right.com.cn firmware** on a Fastweb Italy IPoE connection you may run into some issues since no VLANs are used. The ONT responds to DHCP requests with **a 802.1Q tag for VLAN 0**, which should be handled by properly bridging the WAN as well. Other providers that do rely on VLANs such as 835 won't probably need to resort to the this workaround.
