micro-DPU is the single-port FTTdp "distribution point unit" made by Methode
Electronics
which offers complete modularity with replaceable SFP modules both for uplink
and downlink
(G.hn over twisted-pair, G.hn over coax, 1G and 2.5G Ethernet over Cat-5e
cable).
On-board features:
- 512 MiB DDR3
- 2 x 2.5G SFP via HSGMII SERDES interface to the A3720 SoC
- USB 2.0 Type-C connector
- 4GB eMMC
- ETSI TS 101548 reverse powering via twisted pair (RJ45) or coax (F Type)

There should probably be a more specific compatible string (e.g.
"methode,udpu" prepened here.
