The BL-P1201RS series ONU is an intelligent GPON/EPON terminal product launched by Bai-link Communication Technology Co., Ltd. for industrial IoT IoT communication multi service fusion networks. BL-P1201RS follows the ITU-T G.984.x standard, IEEE 802.3ah, CTC 2.0, 2.1/3.0 standards, and has good interoperability and operability, compatible with OLT devices from mainstream manufacturers such as Huawei/ZTE/FiberHome/Nokia. This device is developed using mature technology and open network standards, with a quasi industrial design that can adapt to complex high and low temperature difference environments. It has strong anti-interference capabilities and meets the requirements of different network working environments, providing efficient, reliable, and fast solutions for IoT communication access.

BL-P1201RS supports 1×GPON/EPON interface, 1×10/100Mbps+1×10/100/1000Mbps RJ45 interface (optional PoE function), and 1×RS485 serial port. The product adopts modular design, supports multiple customization needs, ensures safety and reliability, has a compact size, and low power consumption. The product power supply supports 100-240V~, AC 50/60Hz input, or optional DC12-58V, meeting the requirements of power distribution environment for equipment power supply.

The BL-P1201RS GPON/EPON network supports multi-level split bus type architecture and tree structure, which can meet the needs of various access environments. Using fiber optic as the transmission medium, the entire process is passively transmitted, ensuring reliable and stable operation, and achieving single fiber bidirectional high bandwidth service carrying. GPON supports 2.5Gbps downstream and 1.25Gbps upstream; EPON supports high bandwidth transmission of up to 1.25Gbps/down, and when paired with GPON/EPON OLT devices, GPON can achieve a splitting ratio of up to 1:128, while EPON can achieve a high splitting ratio of up to 1:64, with a network coverage radius of up to 20KM.

The BL-P1201RS ONU device has a power outage notification function, which means that when the outdoor ONT device loses power, it can notify the OLT of its own power outage event through the OAM's Dying Gasp function.

The BL-P1201RS device is equipped with system and hardware level watchdog functions. When encountering uncontrollable factors such as external electromagnetic interference, which can cause data chaos in various registers and memory, program pointer errors, being out of the program area, retrieving incorrect program instructions, etc., it may fall into a dead loop, leading to normal program operation or configuration errors that cause the device to crash. It can automatically restart the device to restore business operation, thereby reducing the maintenance work of engineers.

The BL-P1201RS device has long emission self detection and self shutdown functions. When the device detects its own long emission, it automatically shuts off the ONT optical module to avoid affecting the normal use of other ONU devices under the same PON port.
