H901EPHF PX20++

What are the differences between MPLA and MPLB? What versions are available?

MPLA and MPLB both integrated with4*GE/10GE uplink port, the difference is that MPLA supports 100G slot bandwidth, while MPLB supports 200G.
Currently available version are H901/H902/H903/H907MPLB and H901/H902/H903/H905MPLA.

I have MA5800 with CSHF card. If I use XG-PON and XGS-PON ONTs mixed on a port. How can they share the download/upload bandwith?

When XG-PON and XGS-PON ONTs are mixed on the same PON port of an MA5800 with a CSHF card, they share the same optical wavelength for downstream but use different upstream channels.
In the downstream direction, both XG-PON and XGS-PON ONTs receive data from the same 10 Gbps wavelength. So if the XG-PON ONTs are using 5 Gbps, the remaining 5 Gbps can still be used by the XGS-PON ONTs. The total downstream capacity is shared dynamically among all ONTs connected to that port, depending on traffic demand and DBA (Dynamic Bandwidth Allocation) scheduling.
In the upstream direction, it’s different:
XG-PON uses a 2.5 Gbps upstream channel.
XGS-PON uses a 10 Gbps upstream channel.

What QoS features are supported?

The QoS model implemented on the MA5800 is the differentiated service (DiffServ) model.
This model is based on priorities. In this model, the network identifies each data stream and provides corresponding QoS guarantees for the data streams. Traffic classification and priority marking are the prerequisites for using this model.
This model involves simple packet processing and is highly extendible. It is used for the following services:
*VoD
*Streaming media
*VoIP
*Video conferencing
*Private-line services

What's the power module for MA5800 series OLT?

MA5800-X2: PISB-AC power module PISA: DC power module
MA5800-X7/X15/X17: PILA, -48V DC power module

What is the main architectural advantage of the MA5800?

MA5800 adopts a distributed architecture, meaning each service board has independent forwarding capability. This ensures higher performance, enhances reliability, and supports large-scale 10G PON deployments compared with MA5600T’s centralized architecture.
