25G Burst Mode Bit Error Ratio Tester rBT2250-Semight Instruments

Features

Multi-rate
Burst Rate:9.953/ 10.3125/12.4416/
24.8832/ 25.78125 Gbps
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 a real long-fiber environment, avoiding the influence of long-fiber on delay and jitter

Features and Benefits

Upport burst test of Combo-PON，
Double reset signal, the reset position is adjustable, Combo-pon must have 2 reset signals;
Double packet test
Each data packet has different attenuation, there are transitions 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 rBT2250 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 and cannot adapt to the effects of long-fiber on delay and jitter.
