Distribution network automation terminal DTU controller
The Distributed Station Terminal (DTU) is a core device for distribution network automation, adopting a decentralized architecture. It comes with various models, suitable for ring main units, switch stations, and other applications with 8 and 16 bays, respectively. The basic contents include voltage, current, frequency, power and power factor, and up to 6 groups of modules can be configured. It provides real-time monitoring, remote control, fault detection, and communication for Ring Main Units (RMUs), switchgear, compact substations, cable. This Distributed DTU is designed for protection, measurement, control and communication of interval units in 10kV and below ring main units. Communication Mode Optional: RS-485, CAN bus, Ethernet, IEC 60870-5-103 (IEC-103), IEC 61850 In-house Factory & Technical Team, OEM ODM Custom Electrical. The distribution automation terminal DTU is a distributed, multi CPU, and multifunctional networked measurement and control device.

Typical values for optical modules
The core technical parameters of optical modules include: transmission rate, encapsulation, transmit optical power, receive sensitivity, transmission distance, center wavelength, optical interface type, operating temperature, maximum power consumption, etc. Let's introduce. SFP (Small Form-factor Pluggable) optical modules are compact, hot-pluggable transceivers that enable network equipment to connect seamlessly to fiber and copper links. These modules, including SFP, SFP+, and SFP28, are widely used in enterprise networks, data centers, and carrier-grade deployments. The ROSA, or Receiving Optical Sub-Assembly, is an essential component in optical communications. Currently, there are mainly three central wavelengths of optical modules commonly used: 850nm band, 1310nm band and 1550nm band.
