MGate MB3270-G2

Serial communication device – 2-port advanced serial-to-Ethernet Modbus gateway with 2 RJ45 Ethernet ports, DB9 serial connector, -10 to 60°C operating temperature

Ethernet Interface

• 10/100BaseT(X) Ports (RJ45 connector): 2 (Ethernet cascade or dual subnet configured by software) Auto MDI/MDI-X connection
• Magnetic Isolation Protection: 1.5 kV (built-in)
• Optical Fiber: Read more 100BaseFX Multi-Mode Single-Mode Fiber Cable Type OM1 50/125 µm G.652 800 MHz x km Typical Distance 4 km 5 km 40 km Wavelength Typical (nm) 1300 1310 TX Range (nm) 1260 to 1360 1280 to 1340 RX Range (nm) 1100 to 1600 1100 to 1600 Optical Power TX Range (dBm) -10 to -20 0 to -5 RX Range (dBm) -3 to -32 -3 to -34 Link Budget (dB) 12 29 Dispersion Penalty (dB) 3 1 Note: When connecting a single-mode fiber transceiver, we recommend using an attenuator to prevent damage caused by excessive optical power.Note: Compute the “typical distance” of a specific fiber transceiver as follows: Link budget (dB) > dispersion penalty (dB) + total link loss (dB).
