SmartAX MA5621

The SmartAX MA5621 (MA5621 for short) is the first multi-dwelling unit (MDU) specifically designed for smart grid telecommunication in the industry, which supports natural heat dissipation and provides 2*GE/2*GPON uplink ports and 4*GE/FE+4*RS232 user ports. The MA5621 allows terminal units to remotely collect and transmit required information, for example, to remotely control the power, monitor environment safety, and read meters for billing. The MA5621 also can be used for video monitor services. The MA5621 features a broad temperature range, broad voltage range, low-power consumption, and high stability, and can be used on workbenches and installed in corridors and cabinets.

  • Automatic adaptation to GPON and GE modes: The MA5621 provides two uplink ports that use the small form-factor pluggable (SFP) optical modules to meet different site requirements.
  • Hand-in-hand PON protection..
  • Sealed casting aluminum shell and natural heat dissipation (water-proof, dust-proof, and corrosion-proof).
  • Auto-adaptive GE/FE electrical ports and configurable RS232 serial ports, reducing the number of maintenance times.
  • Support for 6 kV surge protection capability, applying to thunderous and rainy areas.
  • Support for the working temperature ranging from -40℃ to 70℃, meeting extreme weather conditions.
  • Auto-adaptive 9-60 V direct current (DC) input and 90-290 V alternating current (AC) input, facilitating installation.
  • Unified network management and plug-and-play: free of field software commissioning, remote acceptance, remote upgrade and patch installation, and remote fault location.

Dimensions (H×W×D)

44.4mm × 235mm × 180mm

Network-side port The MA5621 provides two uplink ports that use the SFP optical modules and automatically adapt to multiple modes, including GPON and GE. The two uplink ports can be configured as follows:
• 2 × GPON
• 2 × GE (optical)
• 1 × GE (optical) + 1 × GPON
User-side port Four GE/FE (auto-adaptive electrical) ports and four RS232 serial ports (configurable using software)
Operating temperature -40℃ to +70℃
Humidity 5% to 95% (non-condensing)
Heat dissipation mode No fan, natural heat dissipation
Electromagnetic compatibility (EMC) standards • Complies with EN 55022 Class B
• Complies with GB 9254-1998 and GB/T 17618-1998
Power supply AC: auto-adaptive 220 V/110 V
DC: auto-adaptive 12 V/24 V/48 V
Weight 1.5 kg

The MA5621 is installed in an outdoor cabinet for remotely collecting and transmitting required information in the electric system. It connects to two optical line terminals (OLTs) by using two PON ports for redundancy protection and connects to the remote terminal unit (RTU), transformer terminal unit (TTU), feeder terminal unit (FTU), or power meter by using the FE or serial port.
