rBT1250
10G Burst Mode Bit Error Ratio Tester
Semight rBT1250 is specially designed for optical line terminal (OLT) test of passive optical network (PON) applications, and supports 1.25G EPON, GPON, 2.5G XGPON, Combo PON, 10G EPON and 10G XGSPON burst bit error testing and analysis.
- High compatibility – Supports various PON OLT rates of 10.3125 Gbps and below
- Support Combo-PON test – Dual reset signal, support Combo-PON test
- SD test – Individual LOS monitoring/SD monitoring/LOS judgment for each channel
- Built-in clock recovery – It can work in the real long fiber environment to avoid the influence of long fiber on time delay and jitter
Features and Benefits
Support Combo PON for burst testing
Dual reset signals, adjustable reset position, Combo pon requires 2 reset signals;


Double packet test
Each data packet has different attenuation, there are jumps between the phases of different data packets, and there are long consecutive “1” and “0” in the data packet;
Need to simulate the worst 2 ONU signal generation.
Built-in clock recovery, support long fiber test
The built-in clock recovery enables the rBT1250 to work in a real long-fiber working environment, which is basically impossible in other solutions commonly used in the industry, because those systems do not support clock recovery,It cannot adapt to the influence of long fiber on delay and jitter.
