The BL-IEP204T has a built-in AC 220V power supply. It is the latest 4-port Gigabit series industrial-grade ONU product developed and launched by Bai-link Communications. This product complies with the ITU-T G.984/988 international standard and the communications industry standard of the People's Republic of China "Access Network Technology-Gigabit Passive Optical Network" standard, and IEEE 802.3ah international standard, the communications industry standard of the People's Republic of China (YD/T 1475-2006), as well as the CTC2.1/3.0 standard of China Telecom EPON equipment, the PON interface supports both EPON and GPON mode access. The ONU automatically identifies the local OLT mode (GPON or EPON) and activates the corresponding PON mode, thereby completing GPON or EPON adaptive switching access. The IEP2400E-T has good interoperability and operability, and can realize interconnection with OLT equipment from mainstream manufacturers in the industry. The equipment adopts mature technology and open network standards to adapt to complex high and low temperature difference environments, has strong resistance to electromagnetic interference, earthquake and shake resistance, meets the working environment requirements of different industrial sites, and provides efficient, reliable and fast solutions for the industrial Internet of Things. The equipment is safe, stable and reliable, creating a rock-solid industrial IoT Internet of Things that is suitable for continuous operation in the industrial communications field.

        The equipment is designed with mature technology and industry standards. It is simple, fashionable and stable. It is made of high-quality materials.
