H901PISA

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.

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.

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

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.

Which control boards does MA5800 use?

MPLA / MPLB
Provides system control, switching, clock processing, security, and uplink interfaces (GE/10GE).
