The BL-P1203RS series ONU is an intelligent GPON/EPON terminal product from Bai-link Communication Technology Co., Ltd., designed for multi-service converged networks in government and enterprise communications. The product supports ITU-T G.984.x standards, IEEE 802.3ah, and CTC OAM 2.0, 2.1/3.0, offering excellent interoperability and operability. It is compatible with OLTs from major manufacturers such as Huawei, ZTE, FiberHome, Nokia, Alcatel&Lucent, and TP-LINK. The equipment is developed using mature technology and open network standards, featuring quasi-industrial design that adapts to complex temperature variations, resist electromagnetic interference, and is shock-resistant and anti-shake, meeting the requirements of various working environments. It provides efficient, reliable, and fast solutions for communication access.

RS485 meter reading device GPON ONU Bai-link BL-P1203RS(XPON/GPON/EPON)

BL-P1203RS supports 1 GPON/EPON interface, 1x10/100/1000Mbps and 1x10/100Mbps RJ45 interfaces, as well as 2xRS485 and 1xRS232 serial ports. The product is designed with modular features, supporting various customization needs. It is secure and reliable, compact in size, and low in power consumption. The product's power supply supports input from 100-240V AC at 50/60Hz, or (customized DC 12-58V), fully meeting the power requirements of distribution network environments.

GPON/EPON networks support multi-level split bus architecture and tree structures, meeting the needs of various access environments. Using optical fibers as the transmission medium, they offer passive transmission throughout the system, ensuring reliable and stable operation. They enable high-bandwidth services over a single fiber in both directions, with GPON supporting downlink speeds of 2.5Gbps and uplink speeds of 1.25 Gbps; EPON supports uplink speeds of 1.25Gbps and downlink speeds of 1.25 Gbps, providing high-bandwidth transmission. When paired with GPON/EPON OLT equipment, GPON can achieve a splitting ratio as high as 1:128, while EPON can achieve a splitting ratio as high as 1:64, with network coverage up to 20KM.

The Bai-link BL-P1203RS ONU device has a power failure notification function, that is, when the outdoor ONT device loses power, it has the ability to notify the OLT of its power failure event through the Dying Gasp function of the OAM.

The device features system and hardware-level Watchdog capabilities. In the event of irresistible factors such as interference from external electromagnetic fields, which can cause data chaos in various registers and memory, it may lead to program pointer errors, moving out of the program area, and retrieving incorrect program instructions. These issues could result in a dead loop. If the device crashes due to configuration errors or normal operation, it can automatically restart to resume business operations, thereby reducing maintenance work for engineers.

The equipment has the function of long light emission self-detection and self-shutdown. When the equipment detects its own long light emission, it automatically shuts down the ONT optical module to avoid affecting the normal use of other ONT devices under the same PON.

RS485 serial port features:

1. The communication is stable and reliable, supporting full-duplex, high-speed and long-time data transmission without packet loss. It supports users to send large amounts of data simultaneously through serial port and network port without interruption, without pausing during transmission, and without data loss.

2. Serial port supports 2 stop bits, supports less than 8 data bits, and supports baud rate of 921.6K bsp.

3. Working mode: It supports TCP Server, TCP Client, UD mode, UDP multicast and TCPServer/Client coexistence. It connects to 6 destination IP addresses as a client and supports 10 client connections as a server.

4.The baud rate supports 1200 921.6Kbps, and special baud rates can be customized. The data bit supports 5 to 9 bits, and the parity bit can be None, Odd, Even, Mark, or Space. The flow control CTS/RTS, DSR/DTR, XON/XOFF, and 1 to 2 stop bits are supported.

5. Supports DHCP, DNS, and no data restart function.

6. Support the Modbus gateway function of Modbu s TCP to RTU.

7. Support Modbus RTU/DLT645 to JSON.

8. Support MQTT connection, support all kinds of public cloud data transmission and other features.

9. Support RS485 multi-host communication mode.
