micro DPU application

Micro-DPU Series

(Single-Channel, Compact Distribution Point Unit)

Product Overview:

The Methode micro-DPU (or μDPU) is a versatile, compact, single-channel distribution point unit (DPU) that can be deployed in a variety of FTTx situations for ultra-fast broadband service delivery. It is an SDN-ready solution with no dependency on proprietary vendor SDKs instead running a mainline distribution of OpenWRT that can be adapted and optimized for specific operator needs.

*ISO 9001 Certified

KEY FEATURES:

Data rates up to 2 Gbps, leveraging the latest 200 MHz G.hn band-plans standardized in ITU-T G.9960 Amendments 1 and 2
Uplink and downlink interfaces implemented as INF-8074 compliant small form-factor (SFP) modules for complete modularity
Downlink wireline options for G.hn over twistedpair or coax and 1G/2.5G Ethernet over Cat-5e
Operating temperature range -40°C to +65°C, 10W maximum power
Flexible power options including both Reverse Power Feed compliant to RPF ETSI TS 101 548 over twisted pair or coax or local 12V DC power
ITU-T K.21 over-voltage protection
Automatic detection of neighbor μDPUs, with synchronization of TDD time slots to eliminate near-end cross-talk (NEXT)
Compatible with MaxLinear cloud-based VectorBoost platform to eliminate far-end crosstalk (FEXT)
Flexible bandwidth provisioning, supporting both fixed TDD ratios or dynamic time allocation (DTA) on both coax and twisted-pair
Directly supported in mainline OpenWrt

Micro-DPU Functional Block Diagram

The micro-DPU consists of a power supply system and a powerful dual core ARM cortex A53 embedded processor optimized for networking applications. The micro-DPU can be powered using a local 12V to 18V supply or reverse power fed from the customer premises using a compatible ETSI TS 101 548 power injector.

micro-DPU Overview

The micro-DPU was originally conceived as a reverse power fed, network managed, GPON fiber link extender. The uplink SFP cage accepts a GPON ONT SFP module with a standard SGMII interface. However, depending on the case use scenario, the uplink can accept any optical or copper SFP module rated up to a link 2.5Gbps with a standard SGMII or 1000BASE-X electrical interface on the SFP 20-pin connector. The downlink SFP cage can be populated with one of several supported G.hn SFP modules, including variants for single-pair SISO, 2-pair MIMO and F-type for coax, or it can be populated with a 1000BASE-T or 2500BASE-T SFP module for downlinks cabled with CAT-5e. For SISO and MIMO phone line connections the micro-DPU can be reverse powered from the customer premises. For Ethernet over CAT 5e or coax case uses, the micro-DPU can be locally powered using a DC-supply between 12V and 18V. When reverse powered, a small patch cable is needed to jump data between the downlink wireline SFP module and the power splitter built into the micro-DPU. This is why the micro-DPU front bezel includes a dual-RJ connector interface. Viewed from the front, the right-hand most RJ connector is for RPF DC-power and data combined while the left-hand RJ connector is for data only. If the micro-DPU is locally powered, the copper media cable must be connected directly to the input of the downlink SFP modules.
